The wushan bank of three gorges reservoir has been divided into floodplain section , changing section from high level to below level and above flood level section 针对水库库岸再造预测的特点，将三峡库区巫山县段的岩质库岸划分为漫滩段、枯洪水位变幅带、常见洪水位以上段3种类型。

Then it makes a summary of the terrestrial carbon deposition and points out several potential land - origin carbon traces including dam capture , deposition happening in floodplain , estuary and near - shore area , and terrestrial carbon precipitation 之后对陆地碳沉积机制进行了归纳，指出了包括大坝截留，河漫滩、河口近岸带沉积及陆地碳沉降等几种可能的陆源碳踪迹。

In addition according to the comparison of typical floods the impact of floodplain morphology to the flood propagation was studied . no continuous water body in main channel and floodplain and the change of floodplain morphology and the increased flood detention capacity caused the time of flood propagation increasing and the flood types changing in abnormally 同时通过对典型洪水的对比分析，研究了滩地边界条件对洪水运行的影响，认识到由于主槽与滩地水体不连续以及滩地地形的改变，滩地蓄洪能力增大，造成洪水传播时间增长和洪峰峰型的异常变化。

The geographic information systems ( gis ) allows the modulation and simulation of different scenarios and the graphic representation of the different alternatives . in order to present and explain to a non expert public like politicians and the population in the floodplain , multimedia technology will play a valuable role trying to make the decision making process more participated (四)在水利工程管理方面，从旧有的单纯的水利工情数据库扩展到以水利工情信息为基础数据背景的工程风险管理系统，对各类防洪工程在洪水状态下的安全性进行评估、城市防洪工程规划、城市发展与防洪工程相结合、工程实施投资效益分析、工程建设对环境质量的影响等等。

By the analysis and study , it is showed that : 1 ) the lower weihe river main channel was at a balanceable state between aggradation and degradation and floodplain of the lower weihe river is a tiny aggradation state before the construction of the sanmenxia dam ; 2 ) the severe aggradation of the lower weihe river bed is mainly caused by the increasing riverbed elevation at tongguan after the construction of the sanmenxia dam ; 3 ) the main reason leading to the increasing riverbed elevation at tongguan is the unreasonable operation of the sanmenxia reservoir ; 4 ) the rate of the riverbed aggradation at tongguan reach and the lower weihe river reach are speeded by adverse condition of incoming water and sediment recently 然后以实测资料为基础分析研究了三门峡建库前后潼关高程的变化规律以及渭河下游河道的冲淤演变规律，分析研究表明：建库前渭河下游主槽处于动态冲淤平衡状态，滩地处于微淤状态；建库后，渭河下游河道发生严重淤积主要是由于潼关高程的抬升造成的；潼关高程的抬升主要是由于三门峡水库的不合理运用造成的，近期不利的水沙条件加剧了潼关河床的抬升速度和渭河下游的淤积。

Sparedescription : based on the author s research and information from the usa and japan , the development trend of flood control and disaster mitigation in economically developed countries is introduced , including the follow aspects : flood risk management , floodplain management , flood control standard , city rainfall flood storage , levee construction technology , public participation , flood insurance , management of storage and detention zones , flood control investment , study on flood control and disaster mitigation , and formulation of related laws and regulations 描述:根据美、日等国最新文件和资料，结合作者多年的研究，简明地介绍经济发达国家在防洪减灾方面的最新发展趋势.内容涉及洪水灾害风险管理、泛滥原管理、防洪标准、城市雨洪调蓄、堤防建设技术、公众参与、洪水保险、蓄滞洪区管理、防洪投入、防洪减灾科学研究、法规建设等诸多内容

Though the water levels cross one section are almost equal , the velocities differ greatly . at the some cross - section , the velocity in the in the quirk may be double as that on the floodplain . the water surface will rise hi the southern branch because of the improper diffluence ratio , if using the designed diffluence col 淮河入海水道河口段水位值横向分布相差无几，而流速的横向变化较大，泓滩平均流速差最大可达一倍以上，在现有的分流口设计条件下，若按设计的南北汊分流比，南分流口有壅水现象发生，如果南汊分流增大到800m ~ 3 / s左右时，则水流较为通畅。

On the basis of remote sensing technique ' s good characteristic with large - area , multi - time , multi - photograph variety , manifold abundant spectral information and high ground resolution , the fault tectonics frame , river geomorphy ( such as terrace , floodplain , shoal , etc ) and suspended load , etc . were explained after analyzed the fault tectonics , river geomorphy , characteristic in the tm image by gray bar statistics , primary component analyses , tm741 image integration , line convolve enhancement and model recognition etc . especially 9 piece of fault tectonics were explained in this thesis , in succession , the impacts of the factors severally were analyzed 遥感技术具有大范围、多时相、多片种、多层次、含有丰富的光谱信息及具有较高的地面分辨率的特点。本文利用该技术，运用灰阶统计特征分析和主成分分析、 tm741多波段融合、线性卷积增强、模型提取等一系列遥感解译分析方法，分析了断裂构造、河流地貌(阶地、漫滩、沙洲)及悬浮物等在tm遥感图象上的影像特征，解译出了安徽南部断裂构造格架、河流地貌和悬浮物的分布，并新解译出了9条近东西向的断裂。

3 . a three - dimensional - acoustic doppler velocimeter has been used to measure the velocity and turbulence in a compound channel with vegetated and unvegetated flood - plains . particulary in the interface region between main channel and floodplain . the distribution in three coordinate directions of velocity and turbulence intensities and the renolds stresses are presented . the momentum transfer at the main channel flood - plain interface can be described as an apparent shear stress which can be quantified as a function of the local turbulence at the interface 采用adv对滩地种树前后滩槽交界区域的流速场进行了量测。分析了滩槽交界区域的垂线流速、紊动强度和雷诺应力的变化。将滩槽交界的动量传递描述为一表观应力，这个表观应力可以看作是交界面处的脉动函数并将其定量化。
