Abstract

Water resources management and drainage face a great barrage with the higher and higher density of urban development. However, for development of a modern city, the ecology, landscape, and detention ponds are necessary and welcome features. Furthermore, how to expand the functions of the above ponds as multi-purpose shallow constructed lakes might be helpful. There are conflicts between different purposes practically, such as ecology and detention, ecology and water supply. Then it is necessary to adjust the operation strategies of each consideration purpose to reach a maximum efficiency. This study applies the pressure-state-response (P-S-R) framework which is developed from OECD to analyze the available operation rules for water supply, flood detention, and ecosystem maintenance. Furthermore, a suitable strategy could be compromised between the above purposes, and necessary facilities could be designed. A study case is herein proposed and analyzed throughout P-S-R processes, and then the indicators and considerations are offered at the end. Keywords: pressure-state-response, shallow constructed lake, water supply, flood detention, ecosystem maintenance.
