Pasture can be used as creating surface water by accumulating flooding water and water from snow melting in a region where surface and groundwater area limited such as Gobi and steppe regions. Accumulated water in a pond or dam also can be used to manage streamflow in a region where stream and river flow frequently dried due to water shortage. In this study, we study a possibility to increase flow rate of the Selbe River and to supply additional water into the river when the river is dried. We used Rossomahin’s method, which is Q_max=3.2AF^0.52, to estimate maximum flow rate in the Selbe watershed. Water balance method was used to determine how much water would be accumulated in pond. Also we used Matlab software algorithm to the flow rate estimation, and then two results (water balance and Matlab) were compared. According to the results, we can conclude that there are several possible locations found to create ponds for water accumulation in the Selbe watershed. Pond’s capacity and dimension are determined based on the pond’s purposes. For example, pond capacity should be less than 1000 m3 for the pasture irrigations for proper utilize pasture.
