Investigation of the Current Status of the Tanshui River System: A summary

2016-08-09

In early times, the development and management of rivers in Taiwan tended to emphasize water conservancy facilities for water regulation, water utilization, flood control, and hazard minimization, with less ecological consideration. In recent years, due to economic growth, the increase in national income, improvement of the quality of life, and the emphasis on environmental protection and ecological preservation, both the government and people call for the protection and preservation of river ecologies. Therefore, regarding the management of rivers, in addition to the minimization of hazards, it is necessary to put more strength on the concern and preservation of river ecologies. Therefore, laws and regulations are made to conserve the ecology and natural resources. However, current information on river ecologies cannot satisfy the planning and design of environmental protection and ecological conservation when conducting hydraulic engineering. Likewise, it is necessary to investigate and supplement insufficient information. Integrating the information, it can provide necessary references for hydraulic engineering departments in the management and hydro-engineering projects of river environments. Therefore, this project has come into being.

This project covers the three tributaries (Dahan Creek, Keelung River, and Xindian River) of the mainstream of Danshui River. Season 1~3 of the investigation of the mainstream of Danshui River (the watershed to river mouth of Dahan Creek and Xindian River) was completed in 2015. Season 4 of the investigation of the mainstream and Season 1-3 of the tributaries (Keelung River, Dahan Creek, Xindian River, and Jinmei River) will be completed in 2016. Season 4 of the investigation of the tributaries will be completed in 2017. Along the mainstream, 4 fixed sample stations are installed (Waziwei, Zhuwei, Wugu, and Jiangzicui) and 1 supplementary sample station (Taipei Bridge). Along the tributaries, 6 fixed sample stations and 4 supplementary sample stations are installed.

This project aims to investigate the river conditions of the Danshui River System to construct an ecological resource databank. Suggestions are also made in accordance with the environmental and ecological statuses and habitats of creatures for the references of engineers in designing and planning to lower the impact of the environment and ecology when conducting regulatory works.

In addition, it is approached from the perspective of environmental protection and ecological conservation to analyze the flood capacity of the mainstream of Danshui River. Paying dual concern to both the ecology and flood control, it is hoped to accomplish a win-win situation.
