Hydraulic Analysis of the McCook Outlet Manifold
A 1:40-scale model of the proposed McCook Outlet Manifold was tested at the U.S. Army Engineer Waterways Experiment Station (WES). Subsequently, flow conditions in the manifold were calculated...

Total Sediment Loads of Tropical Rivers
Unmeasured and total sediment discharges were computed for 107 sets of data from the Amazon and Orinoco Rivers and their major tributaries. Unmeasured loads were generally small except...

Sedimentation and Flood Protection for the Lower Yellow River
The Lower Yellow River is known for its disastrous floods in the past. After 4 decades without major floodings, rapid economic and population growths along the River have drew concerns...

Dune Profiles Before and After Storm Events in Coastal Massachusetts
It is well known that short-term changes in dune profiles can have a major effect on the severity of storm damage to coastal areas. In light of this, the standardized methodology developed...

Refined Modelling of Water Quality Constituents in a Semi-Enclosed Coastal Wetland Basin
Details are given of the refinements to a numerical model to improve the representation of the advective transport of water quality constituents. The higher order accurate scheme adopted...

Development of the Lake Okeechobee Watershed Phosphorus Transport Model
The Lake Okeechobee watershed phosphorus model was developed to route flows and phosphorus loadings associated with point and nonpoint sources through a watershed transport system, and...

Orange County Florida Landfill Dilute Leachate Wetland Treatment and Restoration System
The Orange County Landfill began operation in 1971 as an EPA demonstration project for the purpose of defining landfill operations in high groundwater table areas. To prevent groundwater...

Environmental Control of Wetland Plant Communities
We have determined hydrologic regimes at a variety of sites while conducting studies to identify factors controlling wetland plant community composition and distribution. We have had relatively...

Surface Flows Over Intertidal Marshes
A marsh-flow measuring device has been designed to quantify the flow across the marsh surface. The fluorometric technique by tracking the visible substance (Rhodamine red dye) applied...

Development of a Two-Layered Groundwater Model for the Taipei Basin
The objective of this paper is to develop a groundwater model for flow simulation in the Taipei basin. A conceptual model of the basin is first developed; the model consists of an upper...

Development of San Gorgonio Pass Groundwater Flow Model I. Model Calibration
A groundwater flow model is being developed for use in management of a planned groundwater storage and recovery program for the Beaumont Storage Unit of the San Gorgonio Pass groundwater...

Modeling Saltwater Intrusion Control Measures in the West Coast Basin
In the 1960's and 1970's the West Coast Basin Barrier was constructed to protect tha major coastal groundwater basin from further salt water intrusion, which had been occurring as a result...

A Model for Low-Drag Landslides
Field observations and experimental records indicate that the primary mode of motion of many large landslides is that of sliding rather than flowing. Most of the shear during sliding is...

Uncertainties of Tailwater in an Inundation Study: Dam Upgrade Optimization for Hazard Reduction
When an upgrade is required for a dam with an inadequate spillway system, the potential impact of tailwater during an extreme storm in an inundation study should be considered. This paper...

Debris Flow Velocity Estimation Methods for Natural Hazard Assessment
Debris flows are a special category of fluid and mass flow phenomena in which natural runoff entrains extremely high concentrations of sediment. The sediment-water mixture has properties...

Federal Levee Effects on Flood Heights Near St. Louis
A physical model of the Middle Mississippi River was used to perform quantitative analyses of Federal levee effects on flood heights. Contrary to some opinions of the general public, these...

Case History: 100-Year Flood Event in San Francisco
San Francisco experienced a 100-year storm in the winter of 1981-2. This is a report of the flooding damage from this event and the actions that the City took to resolve the flooding problems....

Analysis of Cabinet Gorge Dam
After a 1987 inspection of the Cabinet Gorge Dam, Part 12 consultants contracted by Washington Water Power (a private utility based in Spokane, Washington) made several recommendations...

Dam Safety Modifications for Clear Creek Dam Manuscript for ASCE Hydraulics Division 1993 National Conference on Hydraulic Engineering
Clear Creek Dam, an unsafe thin arch dam, was stabilized by constructing a concrete gravity buttress on the downstream face. During the Bureau of Reclamation's (Reclamation) Safety Evaluation...

New Austrian Dam Side-Channel Spillway
The Loma Prieta earthquake of 17 October 1989 damaged the chute spillway at the Austrian Dam near San Jose, California. The replacement spillway, with a higher design discharge of 11,500...
