渠道坡降渠道坡降slope of canalqudao Pojiang渠道坡降(slope of eanal)渠道上、一下游两个断面之间渠底沿水流方向下降或上升的高差与该染段水平长度的比值。也称渠道比降。合理选择渠道坡降,不仅关系到渠道输水能力的大小和渠道的稳定性,而且也影响渠道和建筑物的工程量以及灌溉面积的大小。因此,渠道坡降应根据渠道沿线地面坡度,上、下级渠道水位衔接要求,渠水含沙量及渠道沿线土质等因素,综合分析后合理选定。当水源供水的含沙量较大时,应以防淤作为选择坡降的主要依据;在平原区或提水灌区,供水的含沙量很小时,应以减小水头损失、增大灌溉面积作为主要依据;若地面坡降较陡,土质较轻时,应以防冲作为选择坡降的主要依据。综合利用渠道的坡降还应考虑其它用水部门(发电航运等)的特殊要求。(李恩羊)
