Groins and Vanes Developed Basing Upon a New Concept of Bank Protection
At curved bends, scour at the outer bank always accompanies deposition at the inner bank. A highly efficient river course for flood flow is considered to have a small lateral gradient...
Estuarine Mud Flow Modeling
This paper presents a model for the simulation of selective withdrawal of estuarine mud. This research is part of the investigation of the design of a mud pumping plant as an alternative...
A Stochastic Approach to Sediment Transport in Alluvial Rivers
A dimensionless sediment transport function relation for alluvial rivers has been developed using stochastic approach. The dimensionless function may be applied to estimate suspended load,...
Determining River Stages with Consideration of Backwater Effects
In a recent hydraulic investigation on the Cache River basin, the stages of the Mississippi River at the Beechridge station were found to be necessary downstream boundary conditions for...
Bank Protection at the Middle and Lower Yangtze
The Middle and Lower Yangtze runs through alluvial plains about 1800 km. There are mainly three types of river reaches: straight-slightly sinuous, meandering, and braided. This paper outlines...
Bank Erosion: A Review of British Research
The paper summarizes recent contributions from British geomorphologists and hydrologists. This includes field measurements of processes, modeling of corrasion and mass failure, interactions...
Mechanics of River Bank Erosion and Protection State-of-the-Art Report 3: Federal Republic of Germany
Regulation and bank protection on German rivers and waterways have a long tradition. Major elements are alignment, revetments, groynes, longitudinal dikes and scour protection in bends....
State-of-the-Art Report: Mexico
Design recommendations for groins and spur dikes are presented. For groins the most important ones are: to build them with sloping crests, orientated downstream and maximum spacing of...
Control of Bank Erosion in The Netherlands. State-of-the-art
In the Netherlands the protection against flooding and the effects of inland navigation have always been extremely important. Many problems related to these items, among them erosion and...
Effects of Vegetation on Floods at Four Arizona Sites
Four examples show the effect of vegetation on stage, discharge or frequency of floods. An 8-year growth of trees on the streambed at site 1 increased channel roughness enough to cause...
The Colorado River Simulation System
The Colorado River Simulation System (CRSS) is a comprehensive computer tool designed to assist water resource managers in long-range planning and management of the Colorado River Basin....
Design and Operation of Guard Gates
Guard gates for hydroelectric intakes and low-level outlets are normally intended for operation only under balanced heads. In the case of failure of regulating gates, the guard gate may...
Model Study of Potential Debris Problems at the Proposed Diversion of Clover Fork River, Harlan, Kentucky
A study was conducted at the Waterways Experiment Station in Vicksburg, Mississippi, using a physical and a numerical model, to evaluate the entrance conditions at a proposed tunnel diversion...
Hydraulic Model and Prototype Experience on Old River Overbank Structure
Physical hydraulic model tests of the Old River overbank structure were conducted to investigate the hydraulic performance of the stilling basin and evaluate riprap stability and scour...
Probabilities of Hydrologic Extremes and Risk Analysis
Extreme floods of very low probabilities, e.g., 10-6 and 10-7, are estimated using data on annual flood peaks...
Joint Probability Calculation of Storm Depths
A methodology is presented to estimate exceedance probabilities of rainfall depths over large areas using joint probability. The joint probability estimate combines the frequency distribution...
Issues of Detectability of Climate Change Impacts on the Runoff of a Southeastern River Basin
Can we detect and predict changes in hydrology caused by climate changes? Assuming credible predictions of climate change, can we predict corresponding hydrologic effects? Are uncertainties...
Simulation of Precipitation by Weather-Type Analysis
A new approach that uses weather-type analysis as a basis for stochastic precipitation modeling was developed and tested for Philadelphia, Pennsylvania. The weather types permit the identification...
Effects of Runoff Changes and Sea Level Rise on Salinity in the Delaware River Estuary
The objective of this study is to investigate changes in the spatial distribution of salt in the Delaware Estuary resulting from climate induced changes in freshwater inflows and in the...
Estimation of the Probability of a Precipitation Event Occurring Over a Specified Watershed
A methodology is proposed for making rational flood control decisions when the physical characteristics of the upstream watershed are known and the characteristics of the extreme precipitation...
