Changes in Runoff Volumes of Inland Terminal Lake: A Case Study of Lake Daihai
Abstract The reduction of the runoff to lake has become a common phenomenon of the inland lakes in northwest China, and the quantitative calculation of the driving factors affecting the runoff change has always been a challenge in lake research. In this pursuit, the present study was performed on La...
