White River Fish Screen Project?Hydraulic Modeling
In 1983, Puget Sound Power and Light Company (Puget Power) proposed in a license application to FERC for the overall White River Project replacement of the existing fish screens constructed...
An LPI Numerical Implicit Solution for Unsteady Mixed-Flow Simulation
A Local Partial Inertia (LPI) technique is developed as an option within the National Weather Service (NWS) FLDWAV dynamic flood routing model to enhance its capability to model unsteady...
Hydraulic Performance of Open Channel Breaching
Flood flow in natural channels with floodplains is often confined in the main channel by the presence of levees. The hydraulic performance of these kinds of channels can be seriously affected...
SpatioTemporal Stochastic Open-Dhannel Flow
The de Saint Venant equations are solved as stochastic partial differential equations whose parameters (hydraulic resistance, bed slope, cross-section geometiy, inflow hydrograph, seepage,...
Analysis of Bank Stabilization in Steep Complex Streams Using A Two-Dimensional Model
In cases where the channel is fairly uniform, and not divided, one-dimensional hydraulic models, such as HEC-2, generally give adequate results for scour evaluations and bank protection...
Santa Clara River Fluvial Analysis
The Santa Clara River watershed, located in Los Angeles County, has been subject to rapid increases in population and urban development, resulting in channelization, new bridges, and increased...
Effects of Approach Flow Conditions on Pump Sump Design
An important obstacle to the development of a generalized sump design is the variability of flow conditions in approach areas. The geometry and alignment of the areas immediately upstream...
An Update on Surface Renewal Estimation of Evapotranspiration
The surface renewal (SR) method for estimating sensible heat flux density (H) has been shown to give good estimates of evapotranspiratiou (ET) when used in an energy balance equation with...
Potential Flow Instability Theory and Bed Forms
An extended, generalised version of two-dimensional linearised potential flow theory of fully unsteady fluid flow-sediment bed interaction is presented. In contrast to previous potential...
An Analysis of Characteristics of Basset Force on Particles Accelerating in Arbitrary Flow Field
In present study of solid-liquid two phase flow, the effect of Basset force on a particle moving unsteadily in a non-uniform flow is not very clear. For this reason, the properties of...
State of Delaware-Scour Evaluation Program
The Delaware Department of Transportation (DelDOT) is evaluating the potential for scour at bridges which have a National Bridge Inventory (NBI)-Item 113 Code Rating of 6 (scour susceptible)....
Training for Bridge Inspectors in Stream Stability and Scour
The Federal Highway Administration (FHWA) is now requiring a comprehensive evaluation of bridge scour as part of the National Bridge Inspection Standards (NBIS). FHWA has established January...
Hydraulic Studies for a Large Wetland
Coastal wetlands are highly biologically productive and provide spawning and feeding habitats for many aquatic organisms. As has happened to freshwater wetlands, about half of the tidal...
Habitat Preservation and Enhancement Associated with San Diego Creek Flood Control Channel Improvement
San Diego Creek, an important regional flood control channel in southern Orange County, California, flows 2.4 kilometers through the mixed-use areas of Irvine Center (San Diego Freeway...
Santa Ana River Salt Marsh Restoration: Orange County, California, U.S.A.
As part of the All-River Plan of the Santa Aria River, the 92 acre Santa Ana River Marsh (Marsh) was constructed at the Pacific Ocean outlet in Orange County, California. This project...
Treatment of Wet Weather Discharges in Columbus, Georgia
The City of Columbus, Georgia and the Columbus Water Works (CWW) instigated a combined sewer overflow (CS 0) control program to protect the Chattahoochee River against adverse impacts...
Rock Riprap for Grade Control
Rock chutes (riprap channels on steep slopes) are used as grade control structures to safely conduct a water flow to a lower elevation. Common procedures used for design of rock riprap...
Grade-Control Structures for Salt River Channelization
Soil cement grade-control structures have been designed and constructed in conjunction with channelization projects along the Salt River in Phoenix, Arizona. The structures were designed...
The Impact of Numerical Precision on Optimal Groundwater Hydraulic Control
The numerical precision retained in the formulation of groundwater hydraulic control optimization problems can have significant impacts on the accuracy of the solution. Sources of imprecision...
Drought Experiences of Ohio and Their Applications in the DAR-JAI River Basin of Taiwan
The shortage of water due to droughts could cause tremendous environmental and economical impacts to the affected area such as the unsuitability for aquatic life and the inadequacy for...
