- Abstract:
- The Nan-Shi-Keng mountainous stream located in Shidin township, Taipei county is selected to study the influence of remediation work on the stream in this study. The data, including the Digital Terrain Model (DTM), flow depth, flow velocity, substrate and fish distribution, etc., in the mountainous stream were collected. Three habitat types, pool, run, and riffle, are classified by the criteria of Froude number. The method proposed by Chen and Chen was applied to evaluate the variations of habitat types for the stream before and after remediation. The results clearly show a decrease of pool habitat for the stream after remediation. The value of weighted usable area (WUA) for the pool habitat is decreased by 50% after stream remediation.
