Reservoir Sediment Sluicing?Laboratory Study
Experiments are being conducted in a 12.2 meter long, 0.38 meter high, 15 centimeter wide flume to examine the behavior of reservoir sediment deposits in response to sluicing. Crushed...
Evaluating LNG As a Fuel for Diesel Shrimp Boats
Liquefied Natural Gas (LNG) is being evaluated as a viable fuel for diesel engines. A shrimp boat is being used to evaluate the LNG system. LNG has an economic advantage to diesel fuel;...
Use of Fish Liver Pathology as a Tool for Environmental Assessment (`siabstract)
Despite the recognized value of fish liver pathology as an environmental assessment tool, little guidance is available on the design and interpretation of such studies. Proper study design...
Beach Restoration at Malaga Urban Area: Pedregalejo Case Study
The existence of a beach is a primary factor for the development of the adjacent urban areas. The present paper deals with the restoration project of Pedregalejo Beach (Malaga-Spain) and...
Evaluation of Compacted Inert Paper Solids as a Cover Material
The following paper presents the results of a laboratory test program which focused on compacted sludges or inert paper solids (IPS) as recommended cover (cap) material over existing IPS...
Engineering Aspects of Soil Erosion, Dispersive Clays and Loess
This collection of papers deals with selected engineering aspects of soil erosion, dispersive clays and loess. Two types of erosion are considered?surface and subsurface (piping)?with...
Experiments on Culvert Flow
Laboratory experiments are described which were performed on small-scale models of smooth circular culverts of length-to-diameter ratio varying between 13 and 52, and longitudinal downward...
Laboratory Study of Mud Flows
In the study reported depth profiles and tip velocities were measured for a series of unsteady mud flows generated in a laboratory flume using a dam break scenario. Observation of a wide...
Scour Downstream of High Level Emergency Spillways
The Corps of Engineers has numerous high level emergency spillways (HLES) including some that have the potential for excessive scour downstream during certain flow events. 'Excessive...
Modeling Materials for Protecting Earth Weirs
This paper reports laboratory experiments on various materials used to protect earth weirs. Dumped rock, gabion mattresses, and shaped blocks on a gravel layer were subjected to high velocity...
Improved Robustness of the NWS DAMBRK Algorithm
The combination dam breach and flood routing numerical model called DAMBRK has been developed by the National Weather Service (NWS) for forecasting river flooding events (Fread, 1984)....
Laboratory and Field Determined Seepage (
In order to obtain quick and reliable estimates of seepage, an attempt was made to establish a relationship between one or more of the properties of concrete canal lining and seepage....
Sewer-Septic Tank Hybrid Promises Savings
Until recently the only options for sewage were the septic tank/leach field or conventional sewers. In some cases a hybrid of the two, called the septic tank/effluent drain, is less costly...
Rim-Drive Turbine for Low Head Applications
A turbine design and testing program was undertaken with the objective of developing a standardized turbine/generator arrangement that would be well suited to the 10 to 30 foot head range....
