| 1 | 南京市高淳区城市水网防洪及雨洪资源利用模拟研究显示文摘城市水网的防洪功能是城市社会经济发展的重要保障,同时,现代城市普遍面临水资源短缺问题,其防洪需求应与水资源利用相结合,提高雨洪资源利用效益。固城湖是高淳区最重要的水源地,若无闸门和泵站调控,在丰水年易受洪水威胁。通过闸门和泵站调控后,可将固城湖水位控制在13 m(50年一遇防洪标准)以内;通过水网的雨洪资源利用,在保障防洪安全的前提下,固城湖丰水年可新增供水量约4400万m^3。研究建议在未来的城市建设中进一步加强雨洪资源利用的研究,兼顾水网的防洪效益和水资源利用效益。 | 徐驰 董庆华 张宏雅 张浮平 | 2020 | 中国农村水利水电2020，，5： | 2 |
| 2 | 北疆供水工程应急闸控下的水力响应分析显示文摘为了研究北疆长距离供水渠道应急闸控措施的选取,通过构建一维非恒定流数学模型,对应急闸控下的水力响应进行分析,针对不同应急情景提出闸控方案。结果表明:事故渠段上下游节制闸紧急关闭时,上游闸后及下游闸前水位变幅很大,渠段内水位波动剧烈;适当减小闸前控制水位以引导渠段退水闸的开启,可有效削减闸前水位壅高值,但闸后水位降幅增大;渠首引水闸快速关闭可以有效减小事故段退水和削减闸前水位壅高的压力,非紧急工况下,渠首引水闸保持小流量供水可以维持分水口用水且利于全线恢复供水;事故段上、下游节制闸关闭速率越大,事故段水体控制效率越高,但闸前壅高、水体稳定时间都会相应增大。 | 齐佳硕 崔娅茹 王双银 张雨山 王曦 | 2021 | 水利与建筑工程学报2021，19，1： | 1 |
| 3 | A cultivated area forecasting approach in artificial oases under climate change and human activities显示文摘The cultivated area in artificial oases is deeply influenced by global climate change and human activities.Thus,forecasting cultivated area in artificial oases under climate change and human activities is of great significance.In this study,an approach named GD-HM-PSWROAM,consisting of general circulation model downscaling(GD),hydrological model(HM),and planting structure and water resource optimal allocation model(PSWROAM),was developed and applied in the irrigation district of the Manas River Basin in Xinjiang Uygur Autonomous Region of China to forecast the cultivated area tendency.Furthermore,the catchment export of the MIKE11 HD/NAM model was set to the Kensiwate hydrological station.The results show that the downscaling effects of temperature can be fairly satisfying,while those of precipitation may be not satisfying but acceptable.Simulation capacity of the MIKE11 HD/NAM model on the discharge in the Kensiwate hydrological station can meet the requirements of running the PSWROAM.The accuracy of the PSWROAM indicated that this model can perform well in predicting the change of cultivated area at the decadal scale.The cultivated area in the Manas River Basin under current human activities may be generally decreasing due to the climate change.But the adverse effects of climate change can be weakened or even eliminated through positive human activities.The cultivated area in the Manas River Basin may even be increasing under assumed human activities and future climate scenarios.The effects of human activities in the future can be generally predicted and quantified according to the cultivated area trends under current human activities and the situations in the study area.Overall,it is rational and acceptable to forecast the cultivated area tendency in artificial oases under future climate change and human activities through the GD-HM-PSWROAM approach. | ZHANG Shaobo CHEN Fulong CHEN Jie WANG Jing LI Shaofei LONG Aihua | 2019 | Journal of Arid Land2019，11，3： | 1 |
| 4 | 基于BP与PSO的河口双边界条件逆向推求方法显示文摘在入海河道的防洪调度计算过程中,经常会遇到在确定河口计算区间某一断面水位条件下逆向推求双边界(上游流量、下游潮位)条件的情形。针对基于MIKE 11模型的传统试算法逆向推求河口双边界条件时计算效率与搜索效率低的问题,提出采用BP神经网络和PSO算法来改进传统试算法的优化方法。该方法首先通过MIKE 11模型建立河口双边界与某一断面水位的离线数据库,然后利用BP神经网络建立河口双边界与该断面水位的高精度非线性映射关系,最后以该断面的确定水位为优化目标,采用PSO算法逆向推求进而确定双边界条件的映射关系。晋江河口的实例研究表明:该优化方法与传统试算法相比,在保障计算精度的前提下,计算时长约减少至原来的十分之一,大大提高了计算效率。研究成果可为河口地区防洪调度提供参考依据。 | 易梓杨 郦建锋 钱进 陆卞和 张语航 李丰铎 | 2023 | 人民长江2023，54，2： | 0 |
