Modification to John H. Overton Lock and Dam
The Red River Waterway Project, Mississippi River to Shreveport, Louisiana, will consist of a navigation channel 9 feet (2.7m) deep by 200 feet (61.0m) wide, 5 locks and dams providing...
The Sediment Weighted Histogram Generator and Estimation of Sediment Transport Trends
Long term sediment transport trends may be evaluated using a sediment histogram generator program that was written for microcomputers. Flows can be extracted directly from a compact disc...
Operational Model Development for Salinity Control
The 800 km2 Breton Sound estuary and watershed in Louisiana is being modeled to characterize its salinity regime in terms of hydrometeorological...
An Investigation of Continuity Equation and Flood Routing
In this paper, a flood routing scheme, which gives consideration to the advantages of both the Muskingum method and the unit hydrograph method, is derived by using the continuity equation...
Regionalization of Precipitation Droughts in the Scioto River Basin
By the use of monthly precipitation, droughts are defined based on different truncation levels, namely, 70%, 80%, 90%, and 95%, where a 70% truncation level means that 70% of the recorded...
Status and New Capabilities of Computer Program HEC-6: Scour and Deposition in Rivers and Reservoirs
Last year the Hydrologic Engineering Center (HEC) and the Waterways Experiment Center (WES) incorporated the results from more than ten years of research and development into a new version...
The Hydraulic and Hydrological Interactions Between Urban Sewer Systems and Receiving Waters at High Discharges
In the transition region from sewer to river, the penetration of river flood water into the sewer network or the hydraulic overload of small rivers due to sewer system discharges, may...
Evaluation of the Potential for Release of Residual Coal Tar by Flood Scour at a Superfund Site
To address the potential for release of residual coal tar by flood scour, stream cross-sections, stream discharge and sediment grain size data were collected during the Remedial Investigation...
A Generalized Diffusion Wave Flood Routing Model
A generalized diffusion wave model for flood routing is presented. The model can incorporate detailed data on natural cross sections and river bed geometry. An accurate numerical method...
Maintenance Scheduling for Water Resource Systems: An Application to Advance Maintenance Dredging
A number of investigations have been performed in the recent years to analyze the effect of advance maintenance and to see if it is justifiable. These studies gave promising results but...
Development of a Computer Aided Decision Process for Channel Rehabilitation and Watershed Enhancement Techniques
To assist the engineer in planning and design of channel stabilization measures, an expert system (CADWET) was developed using a commercially available expert system shell program. The...
The Calculation of Flushing Flows for Gravel and Cobble Bed Rivers
Flushing flows are needed to remove fines and sand from a gravel or cobble bed river. A natural stream will have periodic high flows adequate for flushing of fines and sand, but the hydraulic...
Physical Forces Generated by Barge-Tow Traffic Within a Navigable Waterway
Movement of navigation traffic such as barge tows within a restricted inland waterway such as the Illinois, Mississippi, or Ohio Rivers can and will alter the flow field in and around...
Data Acquisition for Determining the Physical Impacts of Navigation
Research is being conducted to determine the physical effects of navigation on the Upper Mississippi River System (UMRS). Extensive field data on various aspects of physical effects of...
Prototype Measurements of Flows Induced by Navigation Tows
Present projections of growth of commerical navigation traffic indicate that annual tonnage per tow and/or number of tows will continue to increase through the foreseeable future. In order...
River Sediment Discharge Study?San Diego Region
Procedures and general results are presented of a recent study performed to estimate the average annual sediment delivery (sand sizes and larger) from sources discharging to the southern...
The Study and Practice of the River Regime Planning and Sediment Management in Gezhouba Project of the Yangtze
Based on the Practice of Gezhouba Project, the first water control project on the mainstem of the Yangtze and the largest hydroproject in China, this paper lays emphasis on importance...
Two-Dimensional Floodplain Modeling
A two-dimensional horizontal finite element numerical model (RMA-2) was applied to a 15 mile (24 km) river channel-floodplain reach in West Germany. Previous applications of such models...
Cumulative Impacts Analysis on a Midwest Fluvial System
The US Army Corps of Engineers recently completed an analysis of the cumulative impacts of erosion control structures on the Platte River in Nebraska. This was done in response to concerns...
Hydraulic Geometry of Mississippi Hill Streams
Hydraulic geometry data based on field and office studies are presented for a series of streams in the Black Creek and Long Creek watersheds in the upland hills of Central and Northern...
