补充资料：渠道流量
渠道流量
discharge in canal
qudao Iiuliang渠道流量(diseharge in eanal)单位时间从渠道某一断面处通过的水量，以米“/秒或升/秒计。常采用下列三种典型流量作为设讨一依据: 设计流量又称正常流量，指作为设计依据的某一特定的代表年份，为满足作物需水要求，在灌水高峰期渠道应通过的流量。设计流量是渠道及渠系建筑物设计的主要依据。 加大流量是指在特殊情况下，如改变作物种植比例，临时扩大灌溉面积、或遇到特大旱情等，渠道应能安全通过的最大流量。一般是根据设计流量，适当选择一个加大百分数来确定。它是设计渠顶高程的依据。 最小流量在渠道对种植面积较小、需水量较少的作物单独供水时，或因水源来水不足而必需缩减供水量时，可出现渠道的最小流量。它主要用于校核渠道水位、确定奎水建筑物的位置。 渠道在输水过程中损失于渗漏和水面蒸发的流量，称为渠道的损失流量。它主要与渠床土质，渠道附近水文地质条件，施工方法和质量，渠道断面形式和尺寸，渠道流量以及渠道长度等因素有关。 有毛流量和净流随之别。毛流量是指包括损失在内的流量，而净流量则是扣除损失后应有的流缝。毛流量与净流量总是相对而言的。某一断面处的流量对一于该断面下游是毛流量，而对上游另一断面却是净流量;支渠渠首流量对本支渠而言是毛流量，对干渠而言却是净流量。 推算各级渠道的流量，一般采用由下级向上级渠道逐级推算的程序。有时还可以采用经验值估算渠道的设计流量，例如在中国每1米，/秒的流量，大约可以灌水田0.7一1.5万亩，旱地1.0一3.0万亩。 (李恩羊)
