MODELING WATER INTAKES IN A SEMI-CONFINED RESERVOIR IN ORDER TO MANAGE THE RECLAMATION REGIME IN THE VICINITY OF AN OPEN COLLECTOR

Abstract

This article presents materials on the creation of a model of water intakes in a semi-limited reservoir in order to study the regularities of failures of an open collector-drainage network, as well as the impact of a decrease in their performance on the reclamation state of irrigated lands, taking into account the regulation of the reclamation regime of the soils of the Shuruzyak collector in the Syrdarya region. The authors consider a single well and a group of interacting wells located in any way, as well as a linear row of wells, of a very significant length near the Shuruzyak collector. The performed calculation shows an estimate of the balance with the identification of individual constituent sources, which ensure the flow rate of wells, which is most reliably produced by constructing filtration grids (graphically or based on modeling) using the method of adding currents. When calculating onshore water intakes in all the considered schemes, including those where the water intake is provided entirely by the inflow of groundwater from the coastline, the effect of an open collector must be taken into account. A decrease in the level under the action of pumping out of wells in such conditions should theoretically occur at all points of the formation, not only in the “capture zone”, limited by the neutral streamline, but also outside it, up to the collector.
