A novel method of determining reservoir characteristic curves based on high-resolution resource satellite data was proposed in this paper, using remote sensing processing and analysis technology. According to the physical characteristics of absorption, radiation and reflection of surface water on ultraviolet, visible, near-infrared bands, etc., the satellite images at different reservoir water level and different periods were processed to analyze the relationship of measured water level corresponding to the water area. Based on the relationship, the relevance among reservoir water level, water surface area, and reservoir capacity was established, so as to determine the reservoir characteristic curve. The method was applied and validated at Jinshuitan Reservoir and Shitang Reservoir in the Ou River Basin. The results show that this method has high accuracy, and the maximum relative error between calculating values and measured values at different water level are -2.33% and -2.11% in Jinshuitan Reservoir and Shitang Reservoir, respectively. The method improves the convenience of determining the reservoir characteristic curve greatly, and the storage capacity of the reservoir can be calculated rapidly by this method.

This study assesses the incremental impact of the first transboundary Payments for Watershed Services (PWS) scheme on water quality in China. Due to the absence of a control situation without the PWS scheme, the synthetic control method (SCM) is applied to construct a counterfactual for the prefecture city Huangshan in Eastern China where the PWS is implemented based on the socio-economic characteristics of more than 75 other prefecture cities. The creation of such a counterfactual is crucial in view of the declining trend in water pollution observed before implementation of the PWS scheme. Despite this downward trend in water pollution, an additional effect of the PWS scheme is observed. This result is not obtained when using any of the other prefecture cities as a placebo to test the robustness of this outcome. The application of the SCM in this study is a promising new avenue for the evaluation of PWS schemes elsewhere where similar control conditions are lacking. However, as we show, its applicability depends crucially on the availability of relevant water quality monitoring data.
