The EPA is conducting studies on the base flow of rivers to effectively maintain and improve river ecology. The results will serve as a reference for environmental impact assessments concerning river flow and river remediation.
River flow in Taiwan has a wide range of variance at times very high and other times low and dry. This is further complicated by dams or barriers in upstream and midstream locations. During drought periods, downstream flow is exhausted, greatly affecting the original shape of the river as well as fish habitat. These changes can seriously impair river ecosystems can be seen as a result of inadequate consideration toward the normal flow of rivers (commonly referred to as “base flow”).
The EPA states that the National Council for Sustainable Development, Executive Yuan, in its Sustainable Development Action Plan asks competent authorities responsible for allocating water rights to consider the environmental base flow of each river segment. Moreover, according to Article 38 of the Development Environmental Impact Assessment Working Guidelines, developers must first assess base flow for construction of weirs, dams, hydropower, or drawing off water. When developing water resources, the maintenance of river base flow must be assessed in order to maintain river ecology. Both water quality and quantity are equally important in efforts to improve river ecology. The EPA states that sharp reductions of pollution discharge have already improved water quality. Now the EPA is carrying out investigative studies on base flow to serve as a reference for environmental impact assessments of river flow and river remediation.
River base flow can be analyzed and assessed for impact on fish habitat via historical methods, experiential methods, hydrological methods, and habitat methods. The EPA uses these methods to analyze the base flow of four rivers: the Hsindian River in northern Taiwan, the Zhuoshui River in central Taiwan, the Kaoping River in southern Taiwan and the Beinan River in eastern Taiwan. On 18 June 2008, the EPA invited organizations and experts in the fields of water resources, fisheries, water quality protection and natural ecology to conduct a study on the characteristics of base flow of rivers in Taiwan and examine principles for determining river base flow. Preliminary suggestions included ensuring ecological functions of base flow, only considering rivers with artificial constructions such as river weirs or dams. Natural streams were not included in the discussion. It was also recommended that the minimum values of either 3 CMS or daily flow duration of Q97 be adopted as base flow. In future river remediation projects the EPA recommends that the above principles are followed to maintain river base flow.
Currently lenient regulations on water rights are causing insufficient river base flow. While waiting for water agencies to adjust water rights, the EPA will widely encourage the establishment of water conservation agreements with enterprises so that the saved water can replenish base flow and increase river base flow to meet ecological needs.
