三门峡水库加入调水调沙阵营,将和小浪底产生怎样的微妙互动?2022-07-05 10:47·大河报大河报·豫视频记者 刘瑞朝图片来源于网络2022年度的黄河调水调沙正在进行中。7月4日,三门峡水利枢纽(三门峡水库)加入进来,为小浪底水库调水调沙提供后续的持续的动力支持。那么,三门峡水利枢纽泄洪调水,与小浪底调水调沙之间有什么样的关系?黄河调水调沙又是怎么一回事儿?又为什么选择小浪底水库担任“领衔主演”?调水调沙20余年来,黄河下游发生了怎样积极的变化?防洪形势如何得到了改善?为此,大河报?豫视频记者将为大家一一揭秘。图片来源于网络【动态】三门峡水利枢纽开闸泄洪 最高下泄量将达4500立方米每秒7月4日13时,三门峡水利枢纽,精准开启闸门,滔滔黄河水,喷薄而出。根据官方说法,三门峡水利枢纽接过了今年黄河调水调沙的接力棒,为小浪底调水调沙提供后续动力。根据了解,三门峡水利枢纽这次调水调沙,是按照黄委会的调度指令,参与黄河的调水调沙。从7月4日13时起,按照2000立方米每秒下泄量,4个小时后达到4000立方米每秒下泄量。调水调沙结束后,按照黄委会调度指令转为汛期正常运用。根据估算,此次下泄水量将达到7.2亿立方米。这对延长小浪底水库使用寿命,增加黄河下游减淤、过洪能力具有重要意义。图片来源于网络【析因】泥沙治理是治黄症结所在 调水调沙将塑造相对协调水沙关系黄河调水调沙,已经走过了20余年的时间。2002年以来,黄河防总在充分考虑黄河下游河道输沙能力的前提下,利用万家寨、三门峡、小浪底水库的调节库容,组织调水调沙,对水沙过程进行有效控制和调节,让不适应的水沙关系尽可能协调,以便于输送泥沙。通过调水调沙,减轻下游河道淤积,最终实现下游河床不抬高的目的。那么,什么是调水调沙?调水调沙,是在现代化技术条件下,利用干支流水库进入下游的水沙过程进行调控,塑造相对协调的水沙关系,减少水库河道淤积,恢复并维持中水河槽。黄河为什么要进行调水调沙?众说周知,黄河是我国第二大河,也是世界上含沙量最大的河流。中上游的黄土高原,土质疏松,水土流失严重,黄河流经此处,携带大量泥沙进入下游,直接造成河道淤积,带来诸多安全隐患。根据公开的实测数据显示,1919—2020年黄河多年平均含沙量每立方米达31千克,中游潼关站多年平均输往下游的泥沙约11亿吨。虽然近些年来黄河输沙量在显著减少,但泥沙问题依然是黄河治理的症结所在。小浪底调水调沙资料图,河南河务局提供【解读】位于黄河干流最后一段峡谷末端 小浪底是防治下游水害重要工程之所以选择在小浪底水库实施调水调沙,是因为它位于黄河干流最后一段峡谷的末端,是防治黄河下游水害的重要控制性工程。2001年工程建成后,小浪底水库形成一个总库容达126.5亿立方米的大型水库。通过与三门峡等周边水库联合调度,实现了下游河道的持续冲刷,有效遏制了下游河道长期以来的淤积态势。黄河水利委员会相关人士透露说,从2002年开始进行黄河首次调水调沙后,小浪底水库累计排沙23.9亿吨,下游河道冲刷泥沙30.5亿吨,有效减轻了黄河下游河道防洪压力,同时,这还减轻了黄河下游防洪压力,基本解除了黄河下游凌汛威胁。小浪底调水调沙资料图【关系】三门峡水利枢纽泄洪 为小浪底调水调沙提供动力支持很多人有这样的疑惑,黄河调水调沙不是小浪底水库的事吗?怎么又牵涉到三门峡水利枢纽?三门峡水利枢纽开闸泄水,在调水调沙体系中又发挥着怎样的作用?大河报?豫视频记者了解到,三门峡水利枢纽是黄河水沙调控体系中的重要组成部分。由于它在黄河中游河段处于优越的特殊地理位置,在汛期洪水过程有较强泥沙调节能力,所以,在与万家寨、小浪底水库联合调水调沙运用中,三门峡水库起着十分重要的承上启下作用。在调水调沙过程中,三门峡水利枢纽逐步加大下泄流量直至敞泄,利用三门峡水库汛限水位以上约5亿立方米水量,冲刷小浪底水库库尾泥沙。这也就是说,位于小浪底水库的三门峡水库,通过调水为小浪底水库调沙提供动力支持。同理,三门峡水库调沙,也需要其上游的万家寨水库通过调水提供动力支持。这将为小浪底水库人工塑造异重流并排沙出库,提供强大动力,直接控制小浪底入库水沙过程和增强小浪底调水调沙后续动力,将有效改善小浪底库区淤积分布和增加水库排沙。图片来源于网络【效果】主河槽最小过流能力大幅提高 下游河道主槽平均降低2.6米调水调沙有多重目的。维持黄河下游中水河槽,实施黄河生态调度和三角洲生态补水。同时,在确保后期抗旱用水安全的条件下,优化水库淤积形态,实现三门峡、小浪底水库排沙减淤。另外,调水调沙检验下游河道整治工程适应性,进一步探索不同运用条件下水库排沙和下游河道泥沙输移规律,丰富调水调沙理论。20余年来,黄河水利委员会连续开展黄河调水调沙,初步遏制了黄河下游河道主槽不断萎缩的状况,平均降低2.6米。主河槽最小过流能力,也从2002年汛前的1800立方米每秒恢复到了5000立方米每秒左右。与此同时,20余年的调水调沙,减少了中小洪水漫滩概率,减轻了滩区灾害损失。【释疑】调水调沙并不是浪费水 而是有效利用了腾库容的水有人认为,调水调沙势必会放掉大量的水,这是不是一种浪费?其实,每年6月黄河进入汛期,按照《中华人民共和国防洪法》要求,7月10日之前必须将水库的一部分水放掉,使水库水位降至汛限水位,为后续发生洪水时留足防洪库容,守住水旱灾害防御底线。水流的挟沙能力与流量的高次方成正比。无论是对水库还是对河道,塑造较大的流量过程下泄,才能把水库排出和下游河床冲起的泥沙送入大海,达到冲刷下游主河槽、恢复过流能力的目的。这样看来,本来用作腾库迎汛的一部分水,被用于塑造最有利于冲淤减沙的流量,致使黄河主河槽过流能力显著提高,下游防控调度空间进一步打开,防洪安全更有保障了。下载豫视频APP,一键找记者来源:大河报·豫视频 编辑:王凤华
