Comparison of DAMBRK With DWOPER for Computing Water Surface Elevations at Stream Junctions
The National Weather Service computer programs DWOPER (Operational Dynamic Wave Model) and DAMBRK (Dam-break) are one-dimensional models using an implicit finite difference method of solution...
Peak Outflow From a Breached Embankment Dam
A relation for rapidly predicting the peak outflow rate from a breached embankment dam has been presented. The prediction equation is based on reliable data from 19 embankment dam failures...
A Frictional Resistance Model for the Analysis of Non-Point Source Pollution Processes
This study experimentally investigated the effect of a permeable bed for steady, laminar and smooth turbulent free surface flow on the Darcy-Weisbach friction factor. Flow velocities and...
Effects on Reservoir Water Quality Caused by Changes in Inflow Plume Hydrodynamics
In this paper, the effects of environmental changes on the hydrodynamic behavior of the Las Vegas Wash inflow into Lake Mead are discussed from the view-point of water quality. It is hypothesized...
CORMIX1: Expert System for Mixing Zone Analysis of Pollutant Discharges Into the Water Environment
The Cornell Mixing Zone Expert System (CORMIX) is an integrated software package for the analysis, prediction, and design of aqueous toxic or conventional pollutant discharges into watercourses....
Water Quality Monitoring of Highway Construction
The primary objective of water quality monitoring, as it relates to highway construction, is to obtain quantitative information to ensure that runoff from the construction site does not...
Single-Channel Alluvial Fan Hydraulics with Application to Design of Medium-Density Projects
Methods to identify flood hazards on alluvial fans are provided by the Federal Emergency Management Agency (FEMA) in their Flood Insurance Study, Guidelines and Specifications for Study...
Hydraulic Design of the Unser Boulevard Crossing
As an integral part of the design process, a comprehensive hydrologic, hydraulic and sediment transport analysis was completed of the proposed Unser Boulevard crossing of Calabacillas...
Partnership in Environmental Design for Brush Creek Flood Control
Brush Creek drains a highly urbanized area in metropolitan Kansas City. A large physical model was used to develop a channel modification design for flood control. The Parks and Recreation...
Regional Flood Plain Management
A flood plain management plan for White Rock Creek in the Cities of Dallas and Plano, Texas was developed. New technologies such as three-dimensional topography, CADD, and remote sensing...
Greenhouse Effect on Estuarine Saltwater Intrusion
A report by the British Department of the Environment calls for research into the effect of a rise in world temperatures on sea levels. Model studies should investigate changes in the...
Interfacial Instability in Highly Stratified Flows
The stability of highly stratified shear flows is dependent on several parameters including the thickness of the interfacial transition layer. Experimental results show that the thickness...
Land Drainage and Estuarine Salinity Response
An investigation is being conducted to (1) quantify the short-term effects of freshwater agricultural drainage on salinity in a tidal creek and (2) evaluate the off-site effects of water-control...
Riprap Stability in Channel Bends
A systematic test series is underway in a large test channel to define the stability of riprap on the outer bank of channel bends. A 'practical equilibrium' concept...
The Effects of Bank Protection on River Morphology
Revetment of bends with radius of curvature to width ratios (R/W) between 1.9 and 3.3 on Red River AR, and Sacramento River CA, does not cause the expected thalweg deepening and channel...
The Role of Vegetation in River Bank Erosion
The purpose of this paper is to describe briefly how streambank vegetation, both roots and shoots, modify the 'skin' or surface layer and how this in turn affects...
Groins and Vanes Developed Basing Upon a New Concept of Bank Protection
At curved bends, scour at the outer bank always accompanies deposition at the inner bank. A highly efficient river course for flood flow is considered to have a small lateral gradient...
Estuarine Mud Flow Modeling
This paper presents a model for the simulation of selective withdrawal of estuarine mud. This research is part of the investigation of the design of a mud pumping plant as an alternative...
Numerical Model Studies of Wetland Hydraulics for Bolsa Bay, California
The Bolsa Bay area, near Los Angeles, presently consists of three distinct regions separated by two sets of culverts. A development is being considered, in which a balance between housing...
Beach Erosion Protection Methods: Case Study of Dar City Tanzania
Coastal Tanzania has been experiencing severe beach erosion. Beach erosion is much felt in coastal cities like Dar es Salaam, Tanga etc. Beach erosion in Dar es Salaam has caused damage...
