中文摘要 | 灌溉,即為增進土地之生產力,以人為之方式取水、輸水,其目的在於提供作物 生長所需之水分,藉補降雨之不足;而配水乃基於田間供需平衡之條件下,以最適當之方式將 水量公平、合理、適時及適量的分配到各田區中。 本文之研究擬以機動性之配水方式進行即時配水作業,應用Factor K之方法,在水源變 動之情況下將配水作業分為枯水期與豐水期二個階段,於枯水期僅提供作物生長所需之水量 為目標,在豐水期則於渠道安全之範圍內儘量取水,除了提供生產所需之水量外,將多餘之 水提供給生活及生態之用水,冀以達到生產、生活、生態三者兼顧及立即反應水源情況之機 動性配水方式。 |
英文摘要 | Irrigation aims to enhance the soil productivity through artificial methods of diverting, drawing and conveying water to supplement soil moistures when rainfalls are insufficient to meet the crop growth needs. Irrigation water distribution is a practice to distribute water equitably and reasonably at appropriate time with adequate rate and amount, taking into account the principle of balanced water supply-demand for the cropped farms. This study attempts to develop a more flexible water distribution model by factor K method which differentiates water distribution operations in water deficiency and abundance periods, under the situation of changing flows of water sources. During the dry period, the irrigated water will be merely to supply an amount of water just for sustaining of crop production; while during the water abundance period, the irrigation plans or schemes will arrange to draw the available water within the limit of canal capacity to supply crop needs, living uses and ecological uses. These show the characteristics of the mobility of the water distributions model presented in the study. |
