Lower Santa Ana River Hydraulic Design for Levee Overtopping
The purpose of overtopping or freeboard design is to minimize damages and catastrophic failure from floodwaters overtopping levees. This case study is presented to show the approach taken...
Scale Effects at Intakes Due to Boundary Layer Growth
Boundary layer development in hydraulic models of intakes based on Froude criteria can be poorly scaled because it is viscosity dependent. The potential for scale effects can be estimated...
Physical Modeling of Heated Discharges into a Stagnant River
An alternative cooling system study was performed for the Damietta Combined Cycle Plant in Egypt. The alternatives included spray canals, helper cooling tower and once-through cooling....
Self-Aerating Spillway Flow
The concept upon which most past analyses are based is that a continuum exists in aerated flow from 100 percent water, to air bubbles in water, to a water-air mixture, to an air-water...
Calibrating a 2-D Fate and Transport Model of Watts Bar Reservoir
A branched two-dimensional water quality model has been developed and tested for the Watts Bar Reservoir, including the Clinch River and Emory River embayments. The general stratified...
1-D and 2-D Analysis of Flood Plain Encroachment
The paper reports on a study into the effects of a local encroachment in a broad regular flood plain. The results of a one-dimensional analysis were compared with the results of an equivalent...
Application of Geographic Information Systems for Flood Risk Mapping
This paper presents an overview of the Federal Emergency Management Agency's (FEMA) efforts to automate flood risk mapping performed in support of the National Flood Insurance Program...
GIS Applications to the Water Resources Development Program of the U.S. Army Corps of Engineers
The ability that a Geographic Information System (GIS) offers to quickly reference multiple data sets to an overall base map and to one another provides the potential opportunity to greatly...
Jet Injection Model Studies for the City of Los Angeles
The Hypersion Treatment Plant for the City of Los Angeles is currently undergoing an expansion project. A major component of this system is a sludge recycling system. And it is essential...
Southwest Pass Training Structure Alternatives
The U.S. Army Engineer Waterways Experiment Station system of computer programs, TABS-2, was utilized to evaluate various structural plans for increasing channel velocities and sediment...
Grid Requirements for Numerical Models Containing Training Works
The numerical modeling of the rapid changes in flow variable in open channel flow systems containing training works, such as dikes, requires special attention in grid development. This...
A
A two-component turbulence model is introduced for depth-average flow calculations in shallow open-channel flows. This model treats the bed-generated turbulence as a background component,...
Far-Field Numerical Model Studies for Boston's New Secondary Treatment Plant Outfall Siting
By the late 1900s, Boston is scheduled to have built a new secondary treatment plant that combines the waste streams from two existing plant, and discharges the resulting liquid effluent...
Hydraulic Design Aspects of the Boston Outfall
The diffuser outfall under design for Boston must have the ability to be purged of seawater upon commissioning or following an accidental flow stoppage. The criteria governing the flushing...
Infiltration Trenches for Urban Runoff Control
A two-dimensional finite element model has been developed to simulate the transient flow in a variably saturated porous medium for the study of infiltration trenches. Parameters such as...
A Rational Approach to Selecting an Optimal Design Storm for Flood Control
A rational methodology is presented herein for determining the optimal design storm frequency when planning for flood protection in new urban areas. The technique was developed from an...
Effectiveness of Wet Detention and Retention Ponds for Improving Stormwater Quality
The most commonly used structural measures for stormwater quality management and control are retention basins, wet detention ponds, and detention with filtration ponds. This paper explores...
Glacial Basin Flow for a Power Operation Model
A power operation model was developed and used to estimate the project energy generation and reservoir level fluctuations. In order to precisely simulate the daily project operation, daily...
Real-Time Water Control Plan for a Flood Control Reservoir
A reservoir operation plan is prepared for a single-purpose flood control reservoir. Real-time precipitation data recorded at the dam is utilized to control the reservoir gate operations....
Utilization of Expert Systems for the Operation of Reservoir Systems
This paper illustrates how knowledge-based expert systems can obtain, organize, document, store, and utilize valuable complex reservoir systems experience, obtained by experienced water...
