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...

Model Complexity Required to Maintain Hydrologic Response
An increasing number of practitioners are using distributed hydrologic models employing kinematic routing. Watersheds are typically represented by a set of overland flow plane and channel...

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...

Evaluation and Testing of Storm-Event Hydrologic Models
Hydrologic models considered for this evaluation include: Areal Nonpoint Source Watershed Environmental Response Simulation (ANSWERS); a kinematic erosion model (KINEROS); Watershed and...

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...

Runoff Simulation, Homestake II Project
Wetlands issues raised in connection with the proposed Homestake II Project required an extremely detailed evaluation of basin hydrology. The Subalpine Water Balance Model (WATBAL) was...

Finite Element Modeling in Free-Surface Hydromechanics
A finite element semi-discrete approximation is applied to the conservation law form of the two-dimensional, depth-averaged free-surface Navier-Stokes equations governing incompressible...

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...

Urban Drainage Calculation Limits for Small Areas
This paper discusses the selection and application of hydrologic techniques in the design of stormwater facilities, with particular emphasis on the selection of hydrologic procedure for...

Federal Microcomputer Software for Urban Hydrology
The purpose of this paper is to describe the development, availability, and general use of selected urban hydrology microcomputer software developed by: U.S. Soil Conservation Service...

Evaluation of Diffusion Models for Flood Routing
A study has been conducted to define the range of conditions with respect to hydrographs and channels encountered by SCS engineers in flood plain/flood control projects and to test two...

Hydrodynamic Response of an Estuary to Storm Forcing
Previous work on the response/sensitivity of an estuarine hydrodynamic model to the choice of model parameters is extended to include a preliminary consideration of wind-generated waves....

Modeling of a Low Head Hydroelectric Project
In order to shorten the time to develop a hydroelectric project at the Corps of Engineers Hannibal Lock and Dam on the Ohio River for the City of New Martinsville, West Virginia, a turnkey...

The BRANCH Model and the Segara Anakan Study
The Lower Citanduy Irrigation Project in Central Java, Indonesia drains through the estuary called Segara Anakan. Due to sediment accretion, the lagoon is filling. With erosion problems,...

Hydrologic Forecasting in the National Weather Service
A description of hydrologic forecasting procedures of the National Weather Service (NWS) is presented. Also included is a description of various hydrologic products produced by the NWS...

Potential Effects of Global Climatic Change on the Tennessee Valley Authority Reservoir System
Rising concentrations of carbon dioxide (CO2) and other 'greenhouse' gases are likely to increase global temperatures and...

Hydroturbine Efficiency and Cavitation Monitoring
The paper describes a microcomputer-based system for monitoring hydroturbine performance and cavitation level. Remote access to the monitoring system provides convenient, rapid, and accurate...

Bay/Delta Hydraulic Model?Thirty Years of Service
The San Francisco Bay and Delta is an extremely complex estuarine system. During the past thirty years, the San Francisco Bay/Delta Hydraulic Model has proven to be a valuable scientific...

Three-Dimensional Modeling of a Stratified Estuary
Development around Choctawhatchee Bay, and reduced productivity, loss of seagrass beds, and higher salinities, prompted the Northwest Florida Water Management District to conduct an investigation...

Harbor Restoration Through Improved Circulation
After several episodes of massive fish kills in Old Pass Lagoon on the Florida Gulf Coast, an investigation was undertaken to identify the problems and propose cost-effective solutions....
