Planning and Implementing a Wide Area Flood Warning System: The IFLOWS Experience
The Integrated Flood Observing and Warning System (IFLOWS) is an interactive hydrometeorological data collection and processing system. It consists of three major subsystems; data acquisition,...

PROFS Role in Modernization of the National Weather Service
This paper describes the overall modernization procedure and the computing infrastructure that will support hydrologic operations in a prototype workstation that will be available in National...

WATFLOOD: A Real-Time, Microcomputer-Based Data Management and Flood Forecast System
WATFLOOD is a menu-driven micro-computer based flood forecasting system incorporating data management programs to enable real-time use of weather radar for flood forecasting. The main...

Geographic Information Systems for Hydrologic Modeling
Geographic information system techniques provide flexible and powerful capabilities for computer processing of spatial data sets integral to flash flood forecasting. Video digitizing or...

Effecting Timely Responses to Urban Flash Floods
Problem identification and decision aid development are important first steps in putting together an effective flood warning plan. Until adequate data exists to allow refinement of runoff...

Simulation Model for Economic Irrigation Project Planning and Design
The principle design parameters considered are: water supply configurations (quantity, source and storage); shapes and sizes of the area to be served; on-farm irrigation techniques; cropping...

100 Years of Sedimentation Study by the USGS
On January 15, 1889, the U.S. Geological Survey began collecting sediment data on the Rio Grande at Embudo, New Mexico. During the past 100 years the U.S. Geological Survey's...

History of the Federal Interagency Sedimentation Project
Since 1939, the date of the Project's inception, the team has operated under the direction of two lead agencies - the U.S. Geological Survey and U.S. Army Corps of Engineers....

Sediment Transport Modelling from Grain Size Data
Grain-size analysis can be useful in determining some of the hydrodynamic aspects of the evolution of a natural sand body. The suite statistics approach minimizes single-sample anomalies...

Highly Concentrated Sediment Loads of the Yellow River
A set of high concentration data for the Yellow River in China is examined and compared with low concentration data and laboratory experimental results....

Sediment Transport Modeling Considerations
In addition to understanding the theory and concepts of mathematical modeling, the engineer or scientist must also have knowledge of the river to be studied, the available data, and the...

ASCE Task Committee on Analysis of Laboratory and Field Sediment Data Accuracy and availability
Alluvial channel observations for laboratory and field conditions have been collected throughout the twentieth century. These data have not been adequately evaluated as to accuracy or...

Task Committee on Analysis of Laboratory and Field Sediment Data Accuracy and Availability
One of the main purposes of the ASCE Task Committee on Analysis of Laboratory and Field Sediment Data Accuracy and Availability is to assemble worldwide sedimentation data from field and...

Criteria for a Sediment Data Set
The transport of sediment through a hydrologic system or basin is an extremely complex phenomenon. Many factors affect this movement. Criteria are established for an 'ultimate' or complete...

Field Data Collection and Analysis of Hyperconcentrations and Mud Flows
Hyperconcentrated flows and mud flows exhibit properties quite dissimilar from Newtonian fluids. In order to further our understanding of such phenomena, field data have been collected...

A Watershed Model of Sediment Transport?Load-I
A watershed sediment transport model has been formulated and optimized upon storm hydrographs and the associated sediment load data for several watersheds that have been urbanized and...

Local Scour at Bridge Abutments
Comparison of local scour depths at bridge abutments computed using different equations yields a large variation in predicted values. To consolidate the fragmented results of previous...

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...

Determining River Stages with Consideration of Backwater Effects
In a recent hydraulic investigation on the Cache River basin, the stages of the Mississippi River at the Beechridge station were found to be necessary downstream boundary conditions for...

Statistical Frequency Analysis of Flood Records
The U.S. Geological Survey, like other Federal agencies, uses Hydrology Subcommittee Bulletin 17 for guidance in statistical frequency analysis of flood records. This paper describes the...
