Management exploitation condition of Amu-Bukhara machine channel

Abstract

In this article discussed current exploitation condition of the largest irrigation and drainage network of the Republic of Uzbekistan - Amu-Bukhara Machine Channel. Main importance of this work – is to develop of an intensive method for predicting emergencies arising during the exploitation condition during the vegetation period, the possibility of applying the method of mathematical modelling in controlling exploitation condition. The aim of the study is to develop a modern, convenient, simple and accessible mathematical tools, which will give reliable material for predicting the flow dynamics in the channel and making the right decision in emergency situations when complex exploitation of irrigation and drainage systems. The research methodology consists of a review of the existing systems of hydrodynamic equations which describes the flow motion, and adoption from them divergent system of equations. Have been developed mathematical model and a computer program which allows solve a wide spectre of tasks for modelling of flow in an irrigation and drainage system with various difficulties with taking account daily regulation.
