The Research of Hydrologic Management with GIS: A Case Study of the Aogu Wetland, Chiayi, Taiwan

Aogu Farm was built on reclaimed land. Because of its rich ecological resources,
Aogu was defined as a "Major Wildlife Habitat" in Chiayi County by the Forest Service
and is also expected to reduce carbon in the plan for the flatland forest. Power pumps
are currently used to irrigate and cultivate the area. However, after becoming the
Forest Recreation Area in the future, Aogu Farm has to reduce the influence of human
beings. However, if the Taisugar Company doesn¡¦t support the plan of Forest Service or
abandons farming and stops the pumping power, the Aogu Wetlands will suffer the
crisis of coastal inundation. Hydrological models have their own characteristics. For
example, inundation models for regional drainage using one-dimensional channel flow,
two-dimensional overland flow, and runoff in the mountains all can be assessed to
solve the inundation problems in the coastal lowlands. Nevertheless, the Aogu
Wetlands, the Case Study area, has both a dry season and a wet season even in the
lowland. When rainstorms occur, the area is unable to discharge the water by gravity
but can depend only on pumps to discharge the water into the sea. Therefore, based
on the need to manage water, hydrological surveys must be conducted to assess the
hydrological impact of continuous rainfall on the Aogu Wetlands and to provide
reference information to assist in the management. In the thesis, I use both the
Geographic Information System (GIS) and the Storm Water Management Model
(SWMM) as analysis tools. Moreover, the different regions are further divided into
watershed and the route of drainage, establishing two kinds of models of watershed
hydrology for precipitation simulations. Finally, to compare these two methods, the Arc
Hydro and SWMM models are used in watershed analysis.
