宜昌站泄流能力变化对葛洲坝设计洪水影响

宜昌水文站是葛洲坝、三峡水利枢纽的设计依据站。葛洲坝水利枢纽动工修建和运行 ,对该站水位流量关系中低水部分产生了影响。探讨了该河段泄流能力的变化对葛洲坝水利枢纽设计洪水有无影响的问题。用1 967～ 1 999年实测资料对宜昌站以汛期平均水位为参数的水位流量关系曲线簇进行了检验 ,大部分年份最大日平均流量、3、7、1 5、30d洪量的偏差在± 4 %之间 ,说明曲线簇推流具有相当的精度。证明了宜昌河段中低水泄流能力的变化对葛洲坝水利枢纽设计流量和校核流量基本没有影响     

南流江流域水资源特点与保护对策

随着工农业发展和人口的增长，南流江流域水资源供需矛盾日益突出，水资源的可持续利用日益显得重要，针对流域水资源特点，提出加强水资源统一管理，实施跨流域调水，加强水资源保护等对策。     

国际水资源保护和管理的最近动态——水与可持续发展

阐述了可持续发展及其要求 ,水在可持续发展中的作用 ,国际关于水资源保护和管理的最近动态。最后提出 ,可持续发展是经济社会以及人口、资源和环境的协调统一 ,应从根本上将“先污染后治理”及“防治污染”改为“避免污染”的战略 ;从传统的整体规划向机能整体性规划发展 ;保护和建立河流系统环境 ;着手研究和解决全球环境问题。

关于非线性浅水波理论中的孤立波解

本文在[1]的基础上,详尽地得到了Boussinesq方程和KdV方程的孤立波解,并对波高和波形进行了细致的分析。为了更好地比较,本文还给出了高阶摄动的孤立波解。     

环保型水性上光油的研制与应用

目前，涂布上光技术已被越来越多的印刷厂家所采用，促使上光油的需求量不断上升。经过近几年的努力，我院研制的环保型水性上光油已取得了突破性的进展，完全能够替代溶剂型水性上光油和油性上光油，由于水性上光油具有无毒、无味、透明感强、无有机挥发物（VOC）的排放，成本低、原材料来源广等特点，在使用中能赋予印刷良好的光泽性、耐折性、耐磨性和化学品性，尤其是它所具有的环保性能特别适合食品、药品和烟草等行业包装印刷材料的加工。     

Water quality assessment of a recently refilled reservoir: The case of Bütgenbach Reservoir, Belgium

Bütgenbach Reservoir is situated in the High Ardennes plateau in eastern Belgium (50°25′N; 6°13′E). It is used principally for flood control and for production of hydroelectric energy. It has been subjected to a previous series of studies because of its eutrophication problems and their impacts on the local economy. Bütgenbach Reservoir was emptied during spring 2004 for dam restoration, being refilled in mid‐September of the same year. Selected physicochemical and biological parameters (temperature, dissolved oxygen, pH, inorganic and organic nutrients, chlorophyll‐a) were measured fortnightly during the lake's productive season (mid‐April to mid‐October 2005) at three sampling sites throughout the water column. The water quality conditions after refilling of the lake were compared to previous studies accomplished at the same sampling sites (prior to emptying the lake). The actual trophic status was mesotrophic to eutrophic, based on the combination of total phosphorous and chlorophyll‐a concentrations, as well as water transparency. Bütgenbach Reservoir generally exhibits good water quality, based on the French water quality system SEQ‐eau. A longitudinal decrease in water quality was observed from upstream to downstream, because mainly of the differences in lake bottom morphology and water residence time, and their impacts on nutrient distribution in the lake.     

Effect of Channel Changes in the St. Clair River During the Present Century

Periodic man-made changes in the outlet of Lake Huron through the St. Clair River date back to the middle of the last century. These artificial channel changes have been well documented during the present century. They consist of dredging for commercial gravel removal in the upper river during 1908–25 and uncompensated navigation improvements for the 7.6-m (25-ft) and 8.2-m (27-ft) projects completed in 1933 and 1962, respectively. The total effect of these changes on the levels of Lakes Michigan and Huron (hydraulically one lake) and on the upper St. Clair River profile was determined with dynamic flow models. The ultimate effect of the above dredging was a permanent lowering of the Lake Michigan-Huron levels 0.27 m (0.89 ft), which represents a tremendous loss of freshwater resource [32 km³ (7.7 mi³)].
