Aquatic Environments and Water Resource Management – A Report on Taiwan-Canada Technological Exchange

2018-11-20

In recent years, the maintenance of biodiversity and the survival of river creatures have begun to be considered in the planning of river engineering and the utilization of water resources. The issues of leaving the proper volume of water for river creatures and maintaining a suitable environment as a habitat for their survival will be important facets for river management in the future.

On August 27 – 30, 2018, the Water Resources Planning Institute of the Water Resources Agency invited Dr. Andrew Paul, an environmental flow expert from the Environment and Parks Bureau of Alberta, Canada visited Taiwan to conduct technological exchange. On the 27th, sponsored by the Water Resources Planning Institute of the Water Resources Agency, Dr. Paul presented the speech “Putting it All Together: Incorporating Environmental Considerations into Water Management Decisions.” He shared the making of habitat suitability curves as well as environmental flow for fishes. Among those who attended were the representative of Alberta, Canada in Taiwan, the Endemic Resources Institute of Council of Agriculture, domestic fish experts, scholars from universities throughout Taiwan, NGOs and other groups, totaling more than 60. On the 28th, the Endemic Resources Institute shared a talk presented by a guest from Canada, “Under-Ice Habitat Selection by Mountain Whitefish (Prosopium Williamsoni) in Northern Alberta: Application of Resource Selection.”

On the 29th, the Water Resources Planning Institute of the Water Resources Agency held expert conference, “A Study of River Native Fish Habitat Suitability Curves and Establishment of Database”, in which Dr. Paul, a Canadian expert, delivered a talk on “Habitat Suitability Criteria Curve Workshops: A Perspective from Alberta.” It provided an opportunity for experts to learn about the process of stipulating the habitat suitability curve in Canada, and how it is applied to environmental flow.

On the 30th, an academic exchange, “Environmental Flows–Five Components of Understanding Environmental Flows” was held at the Department of Hydraulic and Oceanic Engineering, National Cheng Kung University. They also went to inspect the Gaoping River basin: Kouai River, Hongtuqi Bridge, Tengkengkao Bridge, Gouping Bridge, and more for suggestions on future engineering design.

On this occasion, a Canadian expert was invited to Taiwan for technological exchange and sharing their Canadian experience. Since 2009, the Water Resources Planning Institute of the Water Resources Agency had conducted the investigation of the microhabitat and life history of native fish species to construct the habitat suitability curve (HSC) for fishes. Currently, HSC are completed for nearly 30 native fish species, which can be seen as base data for habitat restoration and environmental flow of rivers. In the past, the results of the research endeavors of the Environment and Parks (AEP) of Alberta, Canada were applied to the HSC and River 2D project. This event promoted technological exchange between Taiwan and Canada. The experts and scholars who attended the expert conference affirmed the dedication and efforts on river ecosystem given by the Water Resources Planning Institute of the Water Resources Agency in recent years.
