中文摘要 | 本研究的重點即以室內人工降雨機的輔助,探討不同石塊覆蓋率(0,5,10,20,30%) 及坡度(5,10,20度)影響下對蓄水池截水儲水能力的影響。本研究進行降雨模擬試驗時, 降雨模擬機之土槽頂部鋪成紅土坡,其下鋪有乾淨的含水層砂,如此形成一模擬半受壓╱半 自由含水層(semi-confined/semiunconfined aquifer)。在此紅土坡上挖有五個蓄水池及五口觀 測井,用以量測降雨逕流入蓄水池的截水儲水量及地下水位;連接於降雨模擬機之蒐集器 (collector or measuring tank)用來量測地表逕流量。 本研究的實驗結果顯示,坡度、石塊覆蓋率、地下水位、地表逕流量、及蓄水池的截水 儲水能力等彼此之間具多變化性、無規則性。在不同坡度及不同石塊覆蓋率下,地下水位、 地表逕流量、及蓄水池的截水儲水能力等變化並沒有一定的趨勢,它們彼此之間無一明顯的 門檻值(threshold value)。 概括言之,當坡度為5度時,在部份降雨況下,石塊覆蓋率的增加會減少地表逕流量、 降低地下水位與增加蓄水池之截水儲水能力;當坡度為10度時,石塊覆蓋率的增加會減少 地表逕流量、增加地下水位與減少蓄水池之截水儲水能力;當坡度為20度時,石塊覆蓋率 的增加則會增加地表逕流量及地下水位,而減少蓄水池之截水儲水能力。另外,不論有無石 塊之覆蓋,當地表地質材料之透水係數為加細砂或紅土時,坡度增加則地表逕流量減少,但 可使蓄水池之儲水量增加。 |
英文摘要 | In this study, a rainfall simulator was used in the laboratory to determine the interception capability of ponds with different percentages of stone covering (0, 5, 10, 20, and 30%) and different slopes (5, 10, and 20°). Red soil was placed on top of clean aquifer sand. A simulated semi- confined/semi-unconfined equifer was formed in a soil tank connected with the rainfall simulator. Five ponds and five observation wells were dug along a red soil slope to measure groundwater levels, interception and storage of the ponds from rainfall runoff. The runoff collector (or a measuring tank) connected with the rainfall simulator was used to measure the surface runoff. The results showed that the interrelationships of the slope, percentage of stone covering, groundwater level, surface runoff, and the capability of interception and storage of the ponds were varied and irregular. No systematic patterns were detected for the changes in groundwater level, surface runoff, and capability of interception and storage of the ponds with different stone covering percentages and different slopes. No threshold values were apparent. For a 5°slope, an increase in the percentage of stone covering and a decrease in the amount of surface runoff and groundwater level increased the capability of interception and storage of the ponds. For a 10°slope, an increase in the percentage of stone covering and decrease in groundwater level decreased the amount of surface runoff and the capability of interception and storage of the ponds. For a 20°slope, an increase in the percentage of stone covering and decrease in the amount of surface runoff and groundwater level decreased the capability of interception and storage of the ponds. In addition, irrespective of the percentage of stone covering, and with hydraulic conductivity of the top material close to fine sand or red soil, an increase in slope gradient decreases the surface runoff and increases the storage of ponds. |
