River Kaoping is the largest river in Taiwan. Within the basin, 54% is designated as the drinking water source protection area. It is the main source of water supply the area of Kaohsiung City, Kaohsiung County and Pingtung County due to regional development of population growth, increasing amount of waste water from the township, livestock and industry keep pouring into the River Kaoping. Farming activities such as fruit and beetle nut plantation creates various pollutions that cause deterioration of river water quality. For this reason, Environmental Protection Administration initiated the dismantling project which started in 1999 and completed in 2001. The result was a great improvement in water quality, given that 98% or 470 thousands of pigs were removed from the upper basin. In order to ensure the success of the project, this project was proposed to investigate the potential water pollution sources and possible pig farming spots, using aerial photos and satellite images and relevant data sets. Integrated Water Management Model (IWMM) was used to estimate the amount of pollution of Kaoping River basin and propose strategies for subsequent improvement on water quality. In this project, a three-dimensional display and simulation system was provided for further training, using the data collected in this project
