The Water Erosion Prediction Project: Erosion Parameter Estimation
The USDA Water Erosion Prediction Project (WEPP) includes a large field program for collection of experimental data to evaluate soil erodibility. Rainfall simulation techniques are used...
Input Processor Package for Water System Studies
An input processor package for a water distribution simulation model has been developed and field tested. This preprocessor enables users with little or no computer use experience to directly...
Storms and the Occurrence of a Turbidity Interface/Maxima in a Fresh Water Estuary
A combination of Landsat, field data and modeling analyses reveals a turbidity interface/maxima in the lower reaches of a freshwater tributary or 'estuary.' Mode...
Modelling Changes in Coastal Morphology
A description is given of a newly-developed coastal sediment transport model. Features of the model are the inclusion of cross-shore transport and non-potential suspended load, the latter...
Mid-Scale Laboratory Tests on a Two-Dimensional Movable-Bed Sand Model
A two-dimensional physical model was used to simulate wave-induced scour in front of a concrete dike sloped at 1:4. The tests were conducted at the U.S. Army Engineers Waterways Experiment...
Highly Concentrated Sediment Loads of the Yellow River
A set of high concentration data for the Yellow River in China is examined and compared with low concentration data and laboratory experimental results....
Alluvial Stream Bank Erosion?A 10-Year Study
Results of investigations of bank erosion along alluvial streams between 1977 and 1989 are given. Natural processes were found to dominate, with piping an important but hitherto unrecognized...
ASCE Task Committee on Analysis of Laboratory and Field Sediment Data Accuracy and availability
Alluvial channel observations for laboratory and field conditions have been collected throughout the twentieth century. These data have not been adequately evaluated as to accuracy or...
Task Committee on Analysis of Laboratory and Field Sediment Data Accuracy and Availability
One of the main purposes of the ASCE Task Committee on Analysis of Laboratory and Field Sediment Data Accuracy and Availability is to assemble worldwide sedimentation data from field and...
Field Data Collection and Analysis of Hyperconcentrations and Mud Flows
Hyperconcentrated flows and mud flows exhibit properties quite dissimilar from Newtonian fluids. In order to further our understanding of such phenomena, field data have been collected...
Earthquake Effect on Sediment in Rivers and Deltas
Many authors have studied the age and distribution of the Holocene deltaic deposits of the Mississippi River. Several others have written about the magnitude and the recurrence interval...
Scour Assessment at Bridges
Due to the key role that bridges play in the national transportation system, the Federal Highway Administration has developed a scour evaluation program. This program, issued in the form...
Identifying Causes and Predicting Effects of Bank Erosion
A number of causes of bank erosion in natural and disturbed environments are listed and described. Practical methods of predicting rates and directions of erosion in natural environments...
Hydraulic Mechanisms of Riverbank Erosion
Recent efforts are described to develop an improved understanding of bank failure due to piping in noncohesive layers in riverbanks. The efforts included field surveys and laboratory tests....
Geotechnical Aspects of River Bank Erosion
The principal geotechnical mechanisms of river bank failure are identified on the basis of extensive field investigations on many different river systems. The role of each factor depends...
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,...
A Real-time Approach to Groundwater Monitoring, Prediction, and Remediation
This paper outlines a integrated approach to the problem of predicting and controlling groundwater contamination. The key to this approach is to derive contaminant predictions by combining...
Experience with Cavitation in High Pressure Slide Gates
The Bureau of Reclamation has many years of experience in the design and operation of high pressure slide gates. This paper discusses the historical use of high pressure slide gates by...
Borden Field Data and Multivariate Geostatistics
A large-scale field experiment on natural gradient transport of solutes in groundwater was conducted in an unconfined sand aquifer in Borden, Ontario by extensive monitoring after the...
Model Study of New Madrid Pumping Station
The proposed pumping station on the New Madrid Floodway consisted of a draft tube type sump design (referred to as a formed suction inlet) to eliminate swirl and provide a more uniform...
