Abstract

Damage and imbalance in nature result from excessive exploitation of the land, leading to severe disasters, a backlash from nature itself. “Living with hazards” has become a global response to climate change adaptation strategies, which are gradually replacing construction-oriented disaster prevention facilities as a result of non-structural disaster thinking. Comprehensive reviews and improvement measures must be implemented, particularly at the local level. Rainstorms caused by climate change can be connected with regional open spaces, such as farm ponds and parks, which can divert water flow through trenches to form water networks that should be able to moderate the impact of floods. Farm ponds in Taoyuan County were taken as the subject area in this study. By means of investigation and analyses of current locations of farm ponds and flood hazard GIS simulations based on different precipitations, the study reports on how farm ponds can achieve flood detention, flood adjustments, and flood regulation via water network systems that are formed by water level connectivity and the regulation of storm management. Moreover, with further research of flood hazard maps to better understand different precipitation levels and historical disaster scopes by field investigation, the researcher hopes to outline the fundamentals of flood detention. The research is expected to provide a regulatory tool combining farm ponds, trenches, and canals to be implemented for storm management within spatial design.
