A Study of Efficiency Evaluation of Integration of Water Resource and Spatial Planning in Flood Management to Manage Public Runoff as a Shared Responsibility

Abstract

In recent years under the trend of increasing flooding disaster risk caused by climate change a new concept of runoff sharing has been proposed in Taiwan which is an operation method of allocation based on the area of the catchment area based on the hydrological point of view and considering the hydrological characteristics However the scope of the watershed is also a spatial unit of human economic activities The social and economic development and the distribution of runoff responsibilities obviously present a mutual measurement relationship Also land has a certain social responsibility to handle its own runoff This paper develops the evaluation framework of runoff responsibility efficiency with the connotation of eco-efficiency treats water as a resource and regards the process of using environmental resources in runoff management strategies to obtain the overall benefits of the basin as an input-output environmental efficiency relationship Taking the sub-catchment area sub-catchment area and the different spatial classification of the whole watershed as the basis for setting the scenario plan the corresponding runoff responsibility distribution model is obtained individually and at the same time responding to the trade-offs of each sub-catchment area in the face of different hydrology and land conditions Best distribution efficiency
