A Reservoir Yield Evaluation in an Arid Climate
Yield calculations rarely can be more accurate than roughly plus or minus twenty percent. The same uncertainty is dramatically greater in arid climates where the average annual runoff...
Complex Geomorphic Response to Minor Climate Changes, San Diego County, CA
Precipitation in San Diego County, California over the past several hundred years has been characterized by excursions between periods of relatively low precipitation having durations...
Design Storms and Sizing of Flood Control Facilities
Design stroms which embody the rainfall characteristics of an area are used for the sizing of drainage facilities. The selection of a design strom may significantly influence the design...
Flood Control Improvements on Alluvial Fans
Floodplain management on alluvial fans has become an increasingly important issue with continued growth and urbanization in the southwest. The design of flood control facilities for new...
Risk Analysis as a Tool to Determine Spillway Design Capacities
Lyman Dam is an earth and rockfill structure located on the Little Colorado River approximately 11 miles south and upstream of St. Johns, Arizona. Several studies examining the safety...
Observation of Sediment Resuspension in Old Tampa Bay, Florida
Equipment and methodology have been developed to monitor sediment resuspension at two sites in Old Tampa Bay. Velocities are measured with electromagnetic current meters and suspended...
Shop Creek Stormwater Quality Enhancement Project
The advent of NPDES regulations for stormwater discharges creates a need to verify, on a regional basis, the effectiveness of emerging water-quality control technologies such as extended...
A Branched Mass Transport Model of the Sacramento-San Joaquin Delta, California
A new branched mass (salt) transport model is used to simulate salt transport in the Sacramento-San Joaquin Delta, California. The model uses a two-step procedure to determine the salt...
Example of the Stable Channel Design Approach
This paper shows an example application of a new method being packaged by the US Army Engineer Waterways Experiment Station to aid in the design of stable flood-control channels. A stable...
Stable Channel Analytical Design Method
The Flood-Control Channels Research Program is being conducted at the US Army Engineer Waterways Experiment Station to develop systematic methods for design of stable channels for small...
Guidance on the Selection and Use of Sediment Discharge Formulas
The purpose of this paper is to discuss the sediment function module of the computer program SAM. SAM is being developed as a product of the US Army Corps of Engineers Flood Control Channels...
Design and Construction of Soil-Cement Drop Structures
Soil-cement has been used as an effective and economical slope protection material for embankment dams and stream banks. This paper describes the use of soil-cement in the construction...
Bed Sediments and Bed Forms of the Lower Mississippi River
Approximately 500 bed material samples were collected from the thalweg of the Lower Mississippi River. At each sample location, a sonic record of the bed was obtained. From the appearance...
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...
Evaluation of the ARS Low Drop Grade Control Structure
The ARS low drop grade control structure was developed by Little and Murphy to provide efficient energy dissipation and effective grade control for streams in northern Mississippi. The...
Guard Gate Tests at Tieton Dam
The emergency gate hoist system on the guard gates at Tieton Dam, near Yakima, Washington, was tested as part of the United States Bureau of Reclamation Safety Evaluation of Existing Dams...
Innovative Spillway Design
The Lake Alan Henry Dam, near Lubbock, Texas, will consist of an earth filled embankment, a service spillway and an emergency spillway. The service spillway is designed to handle flows...
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...
Can Erosion Control Meet Regulatory Standards?
An erosion control design method for rainfall/surface erosion is presented that enables the designer to determine design loads and the resulting erosion control requirements. Design loads...
