Stochastic process in Hydrology / Yevjevich, V.

Public ISBD Titre : Stochastic process in Hydrology Type de document : texte imprimé Auteurs : Yevjevich, V. Mention d'édition : W R P Editeur : W R P Année de publication : 1972 ISBN/ISSN/EAN : CI-04832 Note générale : This report understakes 7 chapters. chapter 1 treats the basic concepts and classification of hydrologie process : deterministic, stockastic, and their combinaisons. Chapter 2 demonstrates the techniques of autocorrelation and lag cross correlation as applied to hydrology. Chapter 3 illustrates the spectral and cross spectral analysis of hydrology series. Chapter 4 treats the surplus, deficit and range, and chapter 5 refers to theory of runs. Chapter 6 partially departs from treating techniques for the analysis of stockastic processes in hydrology, and presents the problems of transient coponents in hydrologic series. Chapter 7 succintly teats the problems of intermittent series, or series made such by truncating them and studying only one or both of the two truncated parts. Chapter 8 briefly discusses the place of electronic computers in hydrology and the use of the experimental statical method in generaling samples of known or inferred hydrologic stochastic process.

Mention d'édition : Waters Ressources Publications Editeur : Waters Ressources Publications Année de publication : 1971 ISBN/ISSN/EAN : CI-04836 Note générale : Hydrologic phenomena are simulated as stochastic hydrologic systems in terms of mathematical models whose components are represented by stochastic processes. The proposed stochastic hydrologic model is based on a mathematical formulation of the principle of system continuity composed of component stochastic processes of precipitation, runoff, evapotranspiration plus losses and bazsin storage. Based onvarious assumptions two stochastic waterohed system models are formulated and analysed to illustrate the application of the proposed stochastic hydrologic model. As numerical examples for analysis, the french the French Broad river basin above Bueat Creek, North Carolina is used as the watershed for the annual stosrm - flood model, and the upper Sanganuon river.
