为了准确分析调水工程对水环境的影响,以太湖流域望虞河调水工程为例,针对典型调水过程,对望虞河流域河网进行概化,基于一维水动力模型,模拟分析河网水动力特征,在此基础上,根据研究区域污染源现状,选取典型水质影响因子,通过一维水质模型,分析研究区域调水过程与河网水质特征的响应过程.结果表明:引水调度有效地抬高了研究区域河网水位,平均水位上升1~9cm,在引水时段累计引水3.543亿m3;引水调度期各断面NH3-N平均浓度增量在0~0.187 mg/L之间,除古市桥港入望断面,其余分析断面污染物浓度增量均有大幅度下降.该研究能够为望虞河调水工程的运行管理提供一定的参考依据,同时对望虞河流域治污也有重要的指导意义。

农村供水信息化监管与自动化监控具有广泛的应用前景,但由于起步较晚,技术水平参差不齐,系统建设缺乏依据,各地系统建设多是各自为政、缺乏统一规划和研究,信息利用率低、系统之间共享度较差。本文主要从总体架构设计、软件功能与性能要求、通信与接口设计三个方面对系统标准设置要求进行了探讨。本文根据不同层级农村供水工程管理单位的监管需求,提出了不同层级的监管系统建设方案和监管软件功能、性能要求,兼顾考虑目前市场

本文建立了动床实体模型,研究抚河下游尾闾整治工程实施后抚河新开挖河道段和青岚湖区的水流泥沙运动规律及河道冲淤趋势.选取抚河李家渡站2006年、2008-2012年的径流和输沙数据作为试验系列年的水沙条件,并采用系列年循环试验的方法开展连续试验.结果表明,在试验所示的第30年,抚河新开挖河道段的河槽位于河道左侧的格局逐步形成,其后逐年15m等高线以上出现淤积;试验的第30年,青岚湖淤积发展至湖上段,
山区浅水河道漂石局部区域的水流产生显著的分区,主要包括壅水减速区(T1区)、水流挤压加速区(T2区)、尾涡区(T3区)和尾流扩散区(T4区).利用三维声学多普勒测速仪(ADV)测量了不同水流条件下漂石局部区域水流运动参数,并分析了相对淹没度(h/D,平均水深与漂石有效直径之比)为0.56和1.19时水流的垂向流速和紊动能分布特征.实验表明:T1、T3区流速由减到增,T2、T4区由增到减;所测流速分
