Benefits of low-impact development in rural areas

In Taiwan, it is easy to encounter typhoons or heavy rain events with high rainfall intensity, and urban areas are prone to flooding and causing disasters. Rural areas are no exception. Flooding can cause crop necrosis. The reason may be attributed to the rural areas’s old drainage system or not yet complete drainage system, so the goal is to find the most suitable low-impact development facilities through model simulation, evaluate whether various low-impact developments are feasible, and how much flooding depth and savings can be reduced after installation. How much water is used for future irrigation as a decision-making benefit, and the scope of the setting is planned according to the flow sharing plan set by the government, hoping to provide effective improvement in rural areas.
