| Abstract | Possible variations of hydrological conditions of a small water flow located in the territory of workingout mine field are analyzed. Usolka river in the territory of SKRU-1 mine field of "Uralkaliy" OJSC was considered as an object for investigation. In order to obtain correct estimations, an imitation quasi-1D hydraulic model of Usolka river in Sen-Venan mode, realized in HEC-RAS 4.1.0 software complex, was used. Initial data about current relief were scanned from the large-scale topographic maps, wile the data about land subsidence in the territory of SKRU-1 mine field were presented by "Galurgiya" OJSC. ArcMap v.9.3 software complex has been used for processing of topographic data. Influence of land subsidence processes on variation of hydraulic conditions of Usolka river was analyzed. Necessity of execution of concrete measures on minimizing of negative consequences is estimated. |
