Tennessee-Tombigbee Waterway and the Environment
An interdisciplinary studies process was instrumental developing the controversial Tennessee-Tombigbee Waterway in an environmentally responsible manner. The paper describes measures incorporated...
Hydraulic Study for the Construction of Artificial Islands in Peoria Lake, Illinois
Long-term sediment accumulation in the lake reduced the average depth of the lake from 8 feet in 1903 to 2.6 feet in 1985, which resulted in the deterioration of aquatic habitats and recreational...
Modelling the Effects of Wind on Pavement Runoff
Phase I of this study, the primary focus of this paper, consists of the development of a mathematical model to predict runoff depths from a pavement under uniform wind conditions. The...
Snow-Melt Triggered Debris Flows Affecting Utah's Megalopolis
During the abnormally wet years of 1983 and 1984, debris flows were triggered late in spring on the west flank of the Wasatch Mountains and elsewhere in Central Utah. These debris flows...
Emergency Response to the 1983 Debris Flows Along Utah's Wasatch Front
The wet cycle experienced in Utah culminated in approximately one thousand landslide triggered debris flows caused by rapid melt of unprecedented snow accumulation in the Wasatch Mountains,...
Environmental Degradation of Spawning Gravels in the Tucannon River
The important relationship between upstream soil and water conservation measures and salmonid habitat conditions in the Pacific Northwest is illustrated by way of computer simulations...
Watershed Runoff Forecasting Technique
Based on historical records of up to 57 years, a computer model was developed to establish the precipitation - runoff relationship for four reservoir systems in the Northeast portion of...
Comparison of Peak Discharges of Hydrologic Models
The objective of this paper is to evaluate the predictive capabilities of hydrologic models in estimating the magnitudes and frequencies of flood peaks by comparing them with the values...
Unit Hydrograph Relationships for Small Urban Texas Watersheds
Snyder's unit hydrograph methods are used in a HEC-1 multiple sub-area routing model where the sub-area sizes average one to two square miles in size. However, the Snyder's...
Kissimmee River: Engineering Approaches for Restoration
The Kissimmee River, located in central Florida, was channelized for flood control during the 1960s. Movements by environmental interest groups have produced strong sentiment to restore...
Sensitivity of CUHP-PC Computer Model
The Colorado Unit Hydrograph Procedure (CUHP) consists of effective rainfall reduction and hydrograph convolution processes. The primary assumption is an one-to-one response between rainfall...
Kankakee Dam Discharge Characteristics
The low-head dam on the Kankakee River has flashboards which are installed as the discharge decreases in early summer, to maintain the upstream pool level. In response to concern over...
A Measure of Reservoir Efficiency
The notion of reservoir efficiency is defined for a water supply reservoir operated according to the standard policy, that is, one where the release is constant whenever physically possible....
Stage-Frequency Analysis of Closed-Basin Lakes
Devils Lake in North Dakota is used as a case study for the model development and application. The basis of the relationship developed in this study is the separation of the annual maximum...
Analytical Studies of the Schoharie Bridge Failure
Analytical studies consisted of geomorphic, hydrologic, hydraulic, and erosion analyses including mathematical modeling with HEC-1 and WSPRO, the new FHWA water-surface profile model....
Schoharie Creek Bridge Model Study
On April 5, 1987, a major storm occurred in the Schoharie Creek watershed and the resulting flood caused the bridge to fail. The hydraulic model of the bridge was performed to simulate...
The Life and Science of R. A. Bagnold
The purpose of this paper is to highlight and honor the exciting life and many significant contributions made by Brigadier Ralph A. Bagnold to our understanding of hydraulics and sediment...
Hydrodynamic Modeling of Shallow Lagoons and Lakes
There exist many shallow lagoons and lakes in Florida. With an average depth of 3 meters or less, circulation and transport within these water bodies are significantly influenced by the...
An Approach for Modeling the Upper Chesapeake Bay
To resolve the bay geometry with a minimum number of grid points, boundary-fitted coordinates are employed. A major question is how to prescribe tidal boundary conditions at the Bay Bridge...
Task Committee Activities on Microcomputer Software in Urban Hydrology
This Task Committee of the Surface Water Hydrology Committee has been established with the primary objective of developing an inventory of presently available software and to recommend...
