Automated System for Generalization of Streamgage Major Hydrologic Characteristics over a Long-term Period

A. V. Kokorev, A. V. Rozhdestvenskii†, and A. G. Lobanova

Anew automated system of engineering hydrologic calculations is considered. It is intended for generalization of hydrologic observations data over a long-term period and for practical use in projecting and design, as well as when solving various hydrological problems of engineering hydrology. Great attention is paid: to computation of probability curves from heterogeneous hydrometric observations data and accounting for historical information about record values of hydrologic characteristics; to estimation of random and systematic errors of sample parameters determination and of design quantiles, what is of most importance. The technique being the base of automated system completely corresponds to the regulatory document The Code of Rules (SP) 33-101-2003 “Determination of Major Design Hydrologic Characteristics.”
