Comparison of Headcut Advance Testing and Soil Test Results
This paper presents the results of a study conducted in a flume to determine headcut advance rates of two base soils compacted at various compaction moistures and placement energies. The...

Influence of a Sand Layer on Headcut Advance
The presence of an erodible material layer in the soil profile has been observed to influence headcut movement in earth emergency spillways. Large-scale flume tests were conducted to examine...

Sandstone Materials Used as Riprap
A study was conducted to determine if sandstone materials could be potentially used as riprap. Nineteen rock samples (16 sandstone samples) were collected in six western states. The rock...

West Columbus, OH LPP Gate Closure Analysis - A Study of the Requirements for Multiple Closures
Providing flood protection by levees and/or floodwalls often requires the use of temporary closures, in lieu of the more expensive relocation of highways and railroads, in order to maintain...

Hydraulic Model Studies of Recessed Curb Inlets and Bridge Drains
A large hydraulic model (64 ft long by 10.5 ft wide) was used to test several geometries of recessed curb inlets and three types of bridge drains. Testing was at 3/4 scale for the recessed...

1993 Ground-Water Flooding in the Havana Area
The Havana area in Mason County, west-central Illinois, experienced nearly continuous rises in the water table beginning in the fall of 1992 which created lakes in depressed areas. Water...

A Study on Mathematical Model for Sediment Yield in Mountain Regions with Large Hillside Slopes
Based on the characteristics of water and soil loss in mountain region with large hillside slopes in southwest of China, the equations of runoff formation and sediment yield are obtained....

Size Characteristics of Debris Flow Deposition
The size distribution of debris flow deposition is extremely wide which may contain nearly all particles from clay and colloid to boulder. Particle size and composition have very important...

Thresholds for Gravel and Cobble Motion
Flows necessary to initiate motion of rocks on a lateral bar along the Gunnison River in Black Canyon of the Gunnison National Monument are observed. Gravel and cobbles are painted and...

Identification of A Field Data Collection Program in Delaware Bay
Verification and the subsequent application of a numerical model requires sufficient field data to demonstrate that the model is reproducing the existing hydrodynamics of the modeled system....

Analysis of Sand Movement on Noto Coast by Geochemical Method
The analysis of sand samples by X - ray fluorescent spectroscopy (abbreviated by XRF) gives the ratio of the geochemical elements to construct the sand samples. This shows the geochemical...

Comparison of Infiltration Equations Using Flooding Infiltrometer Data
Based on three flooding infiltrometer tests, 27 hydrographs produced by HEC-1 were used to compare peak discharge, time to peak, and storm runoff volume using three infiltration functions....

A Better Description of Trap Efficiency for Fine Sediment in Horizontal Settling Basins
Settling basin removes sediment from intake water and enhance the benefit of diversion works. In order to economize construction land and cost as well as for agriculture fertilization...

Assessing Stormwater Impacts
The evaluation of stormwater effects to watershed ecosystems must adopt an integrated approach due to the inherent complexity of assessing such environments, arising from the vulnerability...

Urban Runoff Based on Land Use and Particle Size
As point sources have achieved pollution compliance, the focus of pollution abatement has shifted to nonpoint sources. New Federal regulations require wet-weather monitoring of drainage...

Non-Point Source Pollution Reduction
The paper reports on the results of a study to determine the effectiveness of the best management practices (BMPs) for use in the Tampa Bay Watershed. The study aims to determine the efficiency,...

Summary of Highway Product Evaluation Practices and HITEC Needs Survey
This report (CERF No. 94-5012) contains the results from a survey conducted by the Civil Engineering Research Foundation (CERF), the research affiliate of the American Society of Civil...

Bearing Capacity of Soils
Technical Engineering and Design Guides, as adapted from the U.S. Army Corps of Engineers, No. 7 This U.S. Army Corps of Engineers engineering manual...

Minimizing the Probable Maximum Flood
A newly-developed probable maximum precipitation (PMP) estimate for Wisconsin and Michigan reduced precipitation depths by 20%. Should a given area's probable maximum flood...

Predicted and Measured Behavior of Five Spread Footings on Sand
This publication contains the results of a full scale load testing program used to predict and measure the bahavior of five spread footings on sand. These results were presented at the...
