THE IMPORTANCE OF HYDROLOGICAL DATA AND FORECASTING TO THE NATIONAT, ECONOMY AND THE DEFENSE OF THE COUNTRY Er~ The life of mankind is closely related to water. Since the dawn of history, man grasped the importance of water and its indispensability to life itself, deified it, worshiped it, and wove it into many of his legends, water is the cotraveler of every culture. Its presence was instrumental in the creation and the growth of cities; its absence resulted in deserts. It has always been instrumental in the propagation of life, and it con- tinues to play this part to our very day. In his urge to dominate nature, man, gradually discarding his religious prejudices, embarked upon a struggle with the des- tructive forces of water, for the subjugation of its riches and power to his own use, and continuously, from year to year, in the course of centuries, he penetrated its mysteries and registered wondrous victories over it. Water is not always benevolent to man. In the course of time it occurs that flooded rivers strike at the peaceful flow of the economic life of the people, inundate cities, tillages, crops, and wipe out great values, carrying death and destruc- tion in their wake. Water is one of the mighty elements of nature, and in or- Declassified in Part - Sanitized Copy Approved for Release 2012/05/07: CIA-RDP82-00039R000200080011-0 Declassified in Part - Sanitized Copy Approved for Release 2012/05/07 : CIA-RDP82-00039R000200080011-0 dsr to utilize its potentialities In the most rational manner, in keeping with our objectives, it is not only necessary to know the past and present characteristics of its cycle, but also to be t able to foresee the future characteristics. This forecasting } ability allows the necessary time to take measures providing for the rational utilizatim of waters, as well as for countermeasures against the oncoming disasters. Hydrological forecasts of the cycles of rivers and seas, and hydrological data in general, are required by the most varied branches of the national economy and the defense of the country, assuming a paramount, frequently decisive, importance in time of war, Hydrological forecasts are particularly important with re-s lation to the problem of floods, which constitute a national ca1a. mity. Figure 1 is a cut showing the flooded city of Omsk on the Irt'tysh River. The flood occurred on 4 May l92, when, due to obstructions, the water level attained the unusual height of 79$ centimeters, piling up damages into the millions and causing a great loss of lives, The highest flood on record until then oc-curred in 1892, with the flood level at 652 centimeters.

In 1931, the swollen waters of the Dnepr River caused treM ous destructian. A number of villages and some cities were mend inundated; many important industrial plants were threatened; tele- graph lines were partially destroyed and comrnun.cations disrupw ted; and only becai.xse of exceptionally strong countermeasures, the losses, in a number of cases, were kept to a minimum. Of great interest to the hydrological forecasting service are the limits of the rather frequently recurring floods in Lenin- grad, particularly the disastrous flood of 23 September 1924 (see ttNews of the Central Hydrometeorological Bureau TsUMOR, No 1925). An unprecedented flood occurred in January 1937 in the Uni- ted States of America, when the Ohio and Mississippi rivers went on a rampage (Ch. F. Brooks and A. G. Tyssen, t'The meteorology of the great floods in the eastern part of the United States," the Oeag~raph'.caeviel~r, XXVII, 1937) . The flood lasted about two weeks (beginn:i.ng with January 22) and was the greatest in the his-- Cory of the United States. American newspapers devoted much space to the description of the details of this disaster, which em- braced a large part of the territory of the United States. The underlying causes of this flood are considered to be an unusually severe winter with great. accumulations of snow. The sudden thaws and ample rains brought about the unprecedented overflow of the Declassified in Part - Sanitized Copy Approved for Release 2012/05/07: CIA-RDP82-00039R000200080011-0 .. i Declassified in Part - Sanitized Copy Approved for Release 2012/05/07 : CIA-RDP82-00039R000200080011-0 Ohio and Missi,ssippi? rivers. .

In Cincinnati, Ohio, a city of the streets were transformed into swirling rivers, half a million, with trolley car, bust and automotive traffic completely at a standstill, with factories and plants idle. Three gasoline sto- rage tanks in the northern part of the city blew up under the tre-- of the swirling waters, with the resulting fires mendous pressure spreading to a considerable part of the city. The areas affected by the flood were struck by epidemics: tens of thousands suffered with the grippe, pneumonia, etc. buildings were destroyed by the currents, and Numerous over a million people found themselves without shelter.

However, due to the forced ~ draught mobilization of a huge amount of technical - f~cili.~ies, some the flood were saved.

Cairo was guarded against the river by an embankment 18.3 meters high to begin with. Yet, it took the forced draught construction of an additional 0.9 to 1.2 meter embankment superstructure to save the city from the flood. The basic underlying cause of these disasters in the United States is considered to be the arbitrary manner in which the forest and water resources are controlled. The predatory destruction of the forests, embracing huge areas, constitutes the principal reason for the recurrence of droughts and floods, di- sasters from which the United States of America have been suffer. ing so extensively during the recent decades. In France, too, rivers such as the Rhone, Garonne, and the Loire, bring at flood stage considerable suffering to the population of the surrounding areas. The cut shown in Figure 2 shows the inundation in the wes- tern part of India, along the railroad line at the city of Barod. The photograph clearly indicates the extent of the disaster. Figure 2.

Thus the forecast of the Volga River flood an 1926 made possible tamely preparations in a number of places and saved prof nning into the millions, which othervrise would have been party ru a destroyed. In the cases where great floods are known to occur, spe- cial flood-combatting conlmission',~ in close liaison with the hyw drolog'ical forecasting service, are set up for the purpose of initiating on time the proper countermeasures. Thus, in 1931, the Kura and the Araks rivers loosed a flood unprecedented by its force and duration. The countermeasures un- dertaken found their reflection in a decision by the Council of People's Commissars AzSSR dated 23 duly 1931? This decision takes of the fact that, due to the timely countermeasures, only note 2,000 hectares were inundated as against an area of 22,000 hec- tares in the flood of 1920. Item 3 of the above decision is quoted herewith: tiThe class-consciousness of the kolkhoz and the poor-and-middle peas- ant masses, their understanding of the politico economical pro- blems posed by the Party and the Government on behalf of the toil- ing peasant masses in the business of the socialist reconstruction of agriculture, resulted in the organization of these masses and , t" '' Declassified in Part - Sanitized Copy Approved for Release 2012/05/07 : CIA-RDP82-00039R000200080011-0 Declassified in Part - Sanitized Copy Approved for Release 2012/05/07 : CIA-RDP82-00039R000200080011-0 in their hexoic struggle against the flood of 1931. "Entire districts, individual kolkhoze$, villages, ko1~ khoz members, and individual owners, under the skilled leader- sliip of local party and Soviet organs, without in any manner de- tracting from their efforts in the current spring sowing cam-s paign, conducted a heroic struggle against the flood. HA considerable number of kolkhoz members and individual owners from the Agdash area labored several days on end without rest very often in chest--deep water, in their valiant attempt to rescue the Soviet cotton crop from the swirling waters of the Kura. "The timely assistance of the area, rural, party, and So-. viet organizations, the selfless devotion of the engineering and technical personnel, also the personnel of the political organs and the militia of the AzSSR -.- all these accounted for the posi- tide results attained in the unusually severe flood of 1931? ttThe timely investigation of the entire course of the Kura River segregated the spots of the greatest potential danger, where the necessary material and inventory stocks were concentrated, a 24-hour continuous patrol established, a technical and human line of communication established along the entire rock-crumbling front, etc. " Tt was due primarily to the efforts and organizational activities of the supervisory administrative andpolitical per-- Declassified in Part - Sanitized Cop Approved for Release 2012/05/07 : CIA-RDP82-00039R000200080011-0 Declassified in Part - Sanitized Copy Approved for Release 2012/05/07 : CIA-RDP82-00039R000200080011-0 sonnet, that the cotton crop and the peasant labor invested were saved from disaster." The heroic struggle with the June 1936 flood in Central Asia is described in the "Pravda of the Fast" issue of 3 Tune 1936: "In the morning of May 31, the riverbed of the Kara-Darya at Kampyr-Ravat was suddenly shifted to the right of the bridge, over which the narrow-gunge railroad ran across the Khanabad stream, "After thvee hours of pounding by the swollen stream, the pier showed signs of buckling, and at 1400 hours it was washed away. Toward the evening the fourth and -sixth piers of the bridge were washed away. The bridge spans, deprived of their supports, were hanging precariously over the swirling river. At great risk, workers, crawling along the shaky spans, finally succeeded in throwing across some metal cables for the temporary support of the spans.' "In the Fergansk area the water forced its way through the right bank of the Bishka reservoir, flowing along a mountain slope. After two days of incessant toil, the breakthrough was plugged." "The work of protecting the 26--kilometer run of the Kuvasay branch railroad proceeds continuously without a letup." "The situation at the Tentyaksay Dam is stir, very tense.

The most ancient of the civilized peoples left behind them memorials of hydraengineering construction such as dams, aqueducts, and irrigation systems. There is no doubt that such hydroengineering construction required not only the understanding and knowledge of the current cycle of the bodies of water in- volved, but also the ability to forecast the cycles to came, During the period of Napoleon I, a French expedition to Egypt discovered two water-level gauging stations dating back about 4000 years, These gauging stations (nilometers) were un- der the jurisdiction of the priests, who watched the water marks and forecast the crops by the height of the latter, for upon the Nile attaining its flood stage depended the deposition of the fer- 12 - Declassified in Part - Sanitized Copy Approved for Release 2012/05/07 : CIA-RDP82-00039R000200080011-0 Declassified in Part - Sanitized Copy Approved for Release 2012/05/07 : CIA-RDP82-00039R000200080011-0 tie river sits that bore the plentiful oxops in the valley of the Nile, (Foot of e; In France, at the beginning of the 111 cen. fury, a water gauging installation was called a nilometre. See, for exmmp1e, Thomassy, Essal sur, l', dx 1oie, 159, Paris, page 2,) However, in historical chronicles we find little reference to the water level and any other forecasting of the hydrological cycle of rivers, On the other hand, in a whole series of books dating back to antiquity, we find elaborations upon the various methods of weather forecasting based upon animal signs, the moon, the stars, and the like. Thus, hydz'olagical forecasting, as a part of the science of hydrology, has no such elaborate "history" as weather fore- casting - the origin and development of this science pertain to a later day. However, there is no denying that the study of ri- ver cycles and attempts at hydrological forecasting were made in the dim past, Samuii Georg Gmelin, in his Travels over Russia for the ln- -~rwipNy.~ti.wa`awrwnw ~_____ ~ wwYnwr~ww yes ;i.tionw,~af the Three Kingdoms of Nature , in 1771, writes "The day of 25 April, as per my experiments, T consider to be the time when the water in the Volga near Astrakhan' begins to rise; a highly dependable sign, following which the above-~mentjoned change is to come., is the subsequent color of the Volga, which b 13 - I j?j Declassified in Part - Sanitized Copy Approved for Release 2012/05/07 : CIA-R DP82-00039R00020008001 1-0 Declassified in Part - Sanitized Copy Approved for Release 2012/05/07 : CIA-RDP82-00039R000200080011-0 other wprde, Gme1a.n had o~ase~ed ~. comes comp~,ete~.y white.~~ In isa fld stag of the impending max:tmumoo e that an a,ndicata.an o a.mata~.y in the water, becoming apparent appxo~ strong turbidi'~y m flood stage, an obsexvata.on a1s0 20 days ahead of the maxima made by the author thxoughau'b the period of 1923_1932.

This service was engaged in the study of the rivers of France with a view toward establishing the characteristics of their cycles, general as well as special; knowledge of these characteristics was necessary to insure the proper development of hydrological forecasting. The same service was also concerned with meteorological phenomena with a view toward establishing the link between the hydrological and meteorological phenomena; for example, between the amount of atmospheric precipitation and the water volumes of the rivers, etc. In Germany, as far back as 1853, simultaneously with the introduction of the telegraph, the foundations were laid for a hydrological data service, concerned primarily with floods of the Rhine, Elba, Oder, and other rivers. And only in l8$6 were the first attempts at full--scale forecasting made. Throughout the period of 1$70-1890, Germany suffered sev- eral disastrous floods in the basins of the Rhine, Oder, Elba, and other rivers. These forced the creation of some temporary commissions to begin with, and later on, some permanent organi- zations for the study of the causes of these disastrous floods as well as for the development of countermeasures. A commission was set up in Eaden in 1893, with the engi- -l5 classified in Part Sanitized Co Declassified in Part - Sanitized Copy Approved for Release 2012/05/07 : CIA-RDP82-00039R000200080011-0 veers Gonzelli and Teyri in chaarge, for the study of the flood problem of the Rhine In Prussia, the special Water Committee (Nasser Au$sohuss), which was established after the disastrous floods of 1885 and 1F391, was instructed by the GoVernment in 1 92 to find the an- swers to the following direct questions "What are the causes of the recent floods, and does the existing Prussian system of con- trolling and regulating the rivers constitute a contributing fac- tor to the floods and to the disasters in their wake? If the answer is what are the changes to be introduced into the existing system of river control? " Under the supervision of the renowned German hydrologist Keller, the Water Committee began the extensive work of investi- gating the rivers. As a result of this research, the Committee came up with exhaustive answers. These were published in a se- ries of monographs pertaining to the basins of the Oder, Elba, Memel, Pregel, Vistula, Weser, and Ems. In 1902, the W_ assor Aussohuss was abolished, and subse-- quent research was conducted by the Landa talt fur Gewasser_ kunde (Water Economy Control Bureau) in Berlin. Some of the re- cent research worthy of attention are the investigations of the Oder floods over the period of 1903-1913, and of the problems linked with the construction of reservoirs that control the run-- off in the Oder basin. A still more recent work is the detailed monograph by Helmann and Eisner devoted to the summer flooding lb Declassified in Part- Sanitized Copy Approved for Release 2012/05/07 : CIA-RDP82-00039R000200080011-0 Declassified in Part - Sanitized Copy Approved for Release 2012/05/07 : CIA-RDP82-00039R000200080011-0 he iii Oongress of Russian Waterways Personnel, SPR, 1896.) Beginning with 193, the Kazan' water region of the Mini stry of Communications introduced regular telegraphic information on problems of navigation. The data was telegraphed to Kazan' from Rybinsk, Faro- slav&, Kostroma, Kineshma, Gorodets, Nizhn:1.y-Novgorod, Chebok- sar, Simbirk, Samara, Syzran', Vol'sk, saratov, Tsarits-ya, As- trakhan', Perm', Christopol', and Ufa, From Kazan' the data was transmitted in the form of a telegraphic bul;Letin to Rybinsk, Nizhniy-Novgorod, Saratov, and Astrakhan'. The telegraphic bulge-- tin indicated: (1) the water level at the water gauge, and (2) the depth and the name of the shalowest sandbank, if, since the previous bulletin, the change in its depth was in excess of 5 centimeters. Prior to the Great October Revolution, there was very lit- tie hydrological forecasting in Russia. Some individual hydrolo- gists placed their forecasts in various departmental memoranda, in publications, in individual booklets, and in special bulle- tins. This work was conducted in a sporadic manner and without any unified plan. Within the first decade after the Great October. Revolution, such works became somewhat more frequent, but were still few in number. The following forecasts were published: P. B. Mul'tanovskiy, "The expected 'height of the flood stage 1g. , r~ !
