Model-Prototype Study of Overland Flow
Similarity of overland flow hydrographs was investigated. Similarity ratios based on Froude number modeling were tested by using: 1) computed hydrographs by kinematic wave equations, 2)...

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...

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...

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...

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...

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...

Microcomputer Capability: Practitioners' Perspective
Leading practitioners in the water resources engineering field want new graduates who are well grounded in fundamentals and are computer literate. The needs of leading practitioners are...

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...

U.S. Army Corps of Engineers Sedimentation Engineer Manual A. Overview
Until the 1970's, sediment analyses within the Corps of Engineers were mostly confined to estimates of the reservoir sediment storage needed, for the life of the project....

Corps of Engineers EM 1110-2-4000 Chapter 3?Sediment Yield
This paper overviews the chapter on sediment yield, one of the three technical chapters of this new design manual. Corps methods to determine sediment yield primarily feature the use of...

River Sedimentation
This paper discusses Chapter 4 of the U.S. Army Corps of Engineers Engineer Manual of Sedimentation Engineering. The chapter identifies potential river sedimentation problems, associates...

U.S. Army Corps of Engineers Sedimentation Engineering Manual D. Reservoir Sedimentation
This paper discusses Chapter 5, Reservoir Sedimentation, of the U.S. Army Corps of Engineers' Engineering Manual (EM) on Sedimentation Engineering, EM 1110-2-4000. The chapter...

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...
