摘要
提出了一种新的地理信息系统(GIS)方法，在短时间内，在大范围内明确识别空间上高度可能的水力发电地点。该方法的结果在尼泊尔Bhote Koshi流域的一个现有水电站进行了验证。沿着河流一共进行了885次搜索，每次搜索的范围为半径10公里的圆形区域，水头和发电站之间的距离为500米，因此在评估期间确定了2655个极有潜力的地点中的297个。结果表明，52个分集水区具有潜力区，有7个特定水电位置与现有水电项目重叠。该方法仅适用于初步筛选，所得结果对进一步深入开展流域水电潜力工程经济分析的可行性研究具有重要意义。HYDRO Nepal journal of Water, Energy and Environment Issue: 23Year: 2018
A GIS Approach for Rapid Identification of Run-of-River (RoR) Hydropower Potential Site in Watershed: A case study of Bhote Koshi Watershed, Nepal
A new Geographical Information System (GIS) approach is proposed to assess primary potential hydropower site, explicitly identifying highly possible hydropower locations spatially, over a large area in a short time. The results from this approach were validated with an existing hydropower site in the Bhote Koshi catchment in Nepal. Altogether 885 number of searches made along the river streams each covered a circular area of radius 10 km, with distance between headwork and power houses of 500 m intervals, thus, identified 297 highly potential sites out of total 2655 during evaluation. The results indicate that, 52 sub-catchments have potential areas and seven specific hydropower locations overlapped with existing hydropower projects. This approach is suitable for initial screening only and the produced results significantly facilitate further in-depth feasibility study to engineering and economic analysis for hydropower potential of the basin.
