Identification of mathematical model of hydrological processes on hydropost «Selyshe» of the river Southern Boog

Abstract

The task of identification of regression mathematical model for recalculation of the long-term observed data of discharges and water levels of the river Southern Boog of hydropost «Sabariv» on hydropost «Selyshe» which has arisen after liquidation of hydropost «Sabariv» is considered. After unsuccessful attempt of identification of dependence between the data of these two river stations which were observed simultaneously, the assumption of influence of discharges water of Sabariv hydroelectric power station (HPS) has been stated. The mathematical model of hydrological processes on hydropost «Selyshe» which takes into account influence of both Sabariv HPS, and hydropost «Sabariv» is identified multipleparameter nonlinear regression. The new model will enable to expand a number of observed data of hydropost «Selyshe» by the data of hydropost «Sabariv» that will give considerable ecological and economic benefit.
