Sediment Sources Analysis for Peoria Lake Along the Illinois River
The modern-day lower Illinois River flows within a greatly oversized valley formed by an old course of the Mississippi River and glacial outwash events. As a result, the section of the...
Ambient Suspended Sediment Concentration and Turbidity Levels
The temporal variation of suspended sediment concentration and turbidity is an important component of the riverine environment. The maximum rate of discrete volumetric sample collection...
Data Acquisition for Hydrologic GIS
Various data acquisition options for hydrologic oriented GIS are presented. These options include manual digitizing, commercial digital data, satellite products, and automated scanning....
G.I.S. Applications in Nonpoint Source Pollution Assessment
A Geographic Information System (GIS) provides a flexible tool for developing the oftentimes cumbersome soils and land use mapping database required in watershed storm water management...
Geographic Information Systems in Water Resources Management
The management of surface and ground water resources within Southern California is increasingly difficult. As population expands, municipal demands for water are increasing. At the same...
Turbulence and Reynolds Stress Distribution in a Natural River
Turbulence characteristics of ambient flow velocities and their comparison with those generated by the movement of barge traffic within the channel border area in a navigation waterway...
Verification of Clark County Hydrologic Modeling
The Clark County Regional Flood Control District, which includes the Las Vegas, Nevada metropolitan area, has recently adopted hydrologic criteria which are intended to standardize the...
Influence of Wetlands on Streamflow in Illinois
Streamflow records from 30 gaging stations in Illinois were analyzed to assess the influence of wetlands on streamflow. The objective of this research was to determine if streamflow parameters...
GIS Visualization Techniques in Surface Water Resource Planning
Geographic information system (GIS) computer graphic displays of surface water resource conditions provides a means for valuation-by-visualization (VBV) of alternate plans. GIS display...
Diffuser Design for Water Quality-Based Toxics Control
U.S. Environmental Protection Agency regulations require that the discharge of toxic pollutants to the waters of the United States be controlled. These regulatory requirements have made...
Measurements to Calibrate Suspended Sediment Model for Adsorbed Contaminant Transport Study of North Fork Holston River, Virginia
A daily suspended sediment (SS) and mercury transport model was developed for a 25-mile reach of the North Fork Holston River below Saltville, Virginia. Daily streamflow measurements;...
Natural Salt Pollution in the Brazos River Basin
Water quality in several major river basins in the Southwestern United States is seriously degraded by natural salt contamination. The salt originates from geologic formations underlying...
Coastal Watershed Unit Hydrographs and Methods
The results of a study to determine unit hydrograph peak rate factors for South Carolina coastal watersheds are summarized and compared with traditional values. An extension to the SCS...
Wetland Drainage and Streamflow Trends in Illinois
Long-term streamflow records from 30 gaging stations in Illinois were analyzed to assess the impact of wetland drainage on streamflow trends. The objective of the research was to determine...
Verification of WASURO Using the Puerto Nuevo Physical Model Study Results
The Jacksonville District, US Army Corps of Engineers, used the hydraulic design computer modeling program, WASURO, for preliminary design of the Rio Puerto Nuevo Flood Control System....
Rainfall-Runoff Modeling in a Small Urban Watershed
Knights Branch watershed is located in Dallas, Texas, and it covers an area of about 5 mi2 (13 km2). Due to...
Daily Drought Monitoring by the Use of Existing Hydrologic Records
To manage water efficiently in case of drought, an effective drought monitoring method has been of interest. Drought durations and their conditional probabilities are estimated by applying...
An Engineering Analysis of Sedimentation in Tidal Inlets
The engineering comparative analysis of deposition and scour of noncohesive sediments in the neighborhood of bridges over tidal inlets is a unique problem which does not lend itself conveniently...
Numerical Modeling of Proposed Channel Designs (J. F. Baldwin III), California
Ship simulator studies of proposed improvements to navigable waterways are a very important part of any assessment. The John F. Baldwin Channel (JFB) Project (Phase III) is a ship channel...
Drought-related West Tennessee Channel Bank Failures
Massive bank failures occurred in 1988 along a 14-kilometer reach of the lower Obion River channel in Dyer County, West Tennessee where the river flows through an abandoned Mississippi...
