中文摘要 | 本研究應用水文及穩定模組(Combined Hydrology and Stability Model , CHASM) 於不同植 生坡地進行水分移動之案例分析。本研究將環境變數區分為不同的坡形、土壤質地、雨型等, 並加入坡地保育處理方案以探討其入滲與水分移動狀況。研究結果顯示,坡型變化(平面坡、 凸坡、凹坡、山邊溝)轉折處入滲深度較深,其中又以山邊溝入滲效果最佳。土壤質地方面, 以礫石的入滲深度最深;至於植生方面,以無植生的入滲深度最深,草本入滲深度最淺。 |
英文摘要 | Combined Hydrology and Stability Model (CHASM) was applied in this study to analyze different cases for water movement in vegetated slopes. This research separates the environmental conditions into different parameters, such as slope shape, soil texture, rainfall type, and slope conservation treatments, to discuss the infiltration and movement of water. The results show that the deepest infiltration was at the curvature changes of the slope (plane slope, convex slope, concave slope, hillside ditch). Hillside ditch has the best efficiency in infiltration. For the parameter of soil texture, gravel material slope shows the deepest infiltration among others. For cover parameter of vegetation, slope without vegetation shows the deepest infiltration; in contrast, slope with herbaceous vegetation shows the least infiltration depth. |
