water regime
Examples
- Hydrology regime and river channel evolution become complex because of double influences of river flow and tide . there is little appropriate method so far . therefore , when the impact us assessed of water project on flood control , the following aspects should be focused on , river evolution and stability of project - sections , design tidal level , flood - tide combination scheme , pre - project and post - project impacts on river channel , water level and flow condition
长江河口段为潮流河段，径流潮流的双重作用使得区域水文情势、河道演变规律错综复杂，开展防洪影响评价研究时，河道演变及工程段稳定性分析，设计潮位的分析计算，洪潮组合方案拟定，工程前后对河道及水位流态影响的模拟等均是目前尚无十分成熟的方法，需要进一步研究的课题。 - The paper discusses the methods of multi - objective ecological operation of reservoirs , which covers the establishment of legislation systems ; water demands for the basic ecological functions of downstream river channel ; reservoir discharge patterns simulating natural hydrological regimes ; regulation and control of sedimentation and eutrophication of reservoirs ; mitigation of the influences by water temperature stratification ; the operation techniques in pollution prevention and connectivity reinforcement of water systems
