Estimation of Streamflow into Lake in a Representative Data-scarce Lake Basin in the Ordos Endorheic Region in the Yellow River Basin, China
Abstract
Lakes are an important part of the water cycle in endorheic (landlocked) basins, as well as a sensitive indicator of environmental change. Hydrological prediction in data-scarce endorheic (landlocked) lake basins is one of the important issues in hydrological sciences, which is of great significance for hydrological process analysis, lake water resources management, and regional ecological environment protection. In this study, we chose the ungauged Bojiang Lake basin as the study area, which is the representative data-scarce basin in the Ordos Endorheic Region in the Yellow River Basin, China. We applied remote sensing technology to obtain a set of lake area data during 1988-2013, then used the conversion formula of the lake area-volume based on lake topography survey to establish the corresponding lake volume, and finally used the water balance model to calculate the streamflow into the lake. Thus, by effectively coupling remote sensing interpretation of lake area, an empirical formula, and water balance model, we propose an integrated approach to estimate the streamflow into Bojiang Lake during 1988-2013. This set of streamflow data can be used for subsequent analysis of hydrological processes, watershed hydrological simulation, etc. This integrated approach could provide a useful reference to quantify lake streamflow in data-scarce endorheic lake basins.
