补充资料：灌溉渠道
灌溉渠道
irrigation canal
guan’gai qudao灌溉渠道(irrigation eanal)联接灌溉水源和灌溉土地的水道。按其控制范围和灌溉面积大小不同，常分为若干级(见灌溉系统)，组成完整的灌溉渠道网。 灌溉渠道可分为明渠和暗渠两类:明渠修建在地面上，具有自由水面;暗渠为四周封闭的地下水道，可以是有压水流或无压水流。明渠占地多，渗漏和蒸发损失大，但施工方便，造价较低，因此应用最多。暗渠占地少，渗漏、蒸发损失小，适用于人多地少地区或水源不足的干旱地区。但修暗渠需大量建筑材料，技术较复杂，造价也较高。 灌溉渠道需具有一定的过水能力，以满足输送或分配灌溉水的要求;同时还必须具有一定水位，以满足控制灌溉面积的要求。灌概渠道的数量多，工程量大，影响面广，因此除应有合理的规划布局外，还应对其设计流量、流速、坡降以及纵横断面尺寸等进行精心设计。(李恩羊)
