Estimation of Flash Flood Potential for Large Areas
A methodology for determining the potential for flash floods in small basins within large geographical areas is presented. Geographical Information Systems (GIS) technology is used to...

1995: Where the Past (Paleoflood Hydrology) Meets the Present, Understanding Maximum Flooding
Paleoflood hydrology has become accepted in the scientific, engineering, and regulatory communities and increasingly is being used to complement engineering hydrology throughout the Rocky...

Monitoring Scour at Bridge Piers in Snohomish Co., WA
Washington State, Snohomish County Public Works Department is using a new Fixed Mechanical monitoring device, to augment its current program of monitoring scour at bridge piers. The Public...

Estimation of the Probable Maximum Rainfall and Snowmelt Floods Via Physically Based Model of River Runoff Generation
Disastrous floods can be caused by unusual combinations of hydrometeorological factors and river basin conditions that have not been observed during a long observation period. The physically-based...

System of River Floods Warning in Ukraine
The diversity of climatic, geomorphologic, and soil conditions causes significant space differences in the conditions of river flood formation in Ukraine. The Carpathians region is the...

Application of GIS Technology to Floodplain & Habitat Analyses
A long-term flood control and maintenance plan for the Mojave River, located in southern California, is currently being developed to satisfy permit requirements for state and federal regulatory...

Design of Riparian Habitat Replacement in Active Floodplains
Conventional flood control engineering techniques and approaches that have been traditionally been applied are now challenged by the public and no longer readily available as floodplain...

Suspended Sediment Loads in Dry and Wet Years
Many factors other than water discharge influence the suspended sediment load in rivers. The climate condition is one of the factors. It is expected that the relation between Qs...

Overview of the US Army Corps of Engineers Flood Control Channels Research Program
The objective of the Flood Control Channels Research Program, currently being conducted at the US Army Engineer Waterways Experiment Station, is to develop design guidance and systematic...

Use of Channel Forming Discharge Concepts for Flood Control Channel Design
Evidence suggests that for perennial and ephemeral rivers that are in regime, bankfull flow is strongly correlated with channel morphology. Evidence suggests that this discharge is also...

Vegetative Roughness in Flood Control Channels
Laboratory flume tests and field evaluations were undertaken as a part of the Flood Control Channels Research Program to determine hydraulic roughness values for various types of floodplain...

Hydraulic Effects of Habitat Structures in Flood Control Channels
Three field sites have been established and laboratory flume experiments begun to assess the effect of habitat enhancement measures on water-surface profiles and local scour in flood control...

Application of Mathematical Models for Flood Forecasting in Sri Lanka
With the introduction of microcomputers, the application of mathematical models in water-resources planning and forecasting became increasingly popular during the last decade in Sri Lanka....

Operational Aspects of Warning
Uzbekistan is referred to as the region where the most dangerous natural phenomena are: mudfloods, floods, and avalanches. During the last decades the areas of their manifestation were...

A Paradox at the Rocky Mountain Arsenal, Colorado: Benefits of Applied Research
The Rocky Mountain Arsenal (RMA), which is located north of Denver, Colorado, was a manufacturing site for chemical weapons during World War II and pesticides for several decades after...

Simulation of Interaction between Canal Regulation and Groundwater
l-D canal routing module has been developed to perform the operation of controlled structures for regulating flow in the canal network system and incorporated in the Three-Dimensional...

Reservoir Sediment Management Practices of the Los Angeles County Department of Public Works
The Los Angeles County Department of Public Works (Department), which includes the Los Angeles County Flood Control District, owns and operates 15 major flood control dams. Most of these...

Debris Basin Design Procedures
Debris basins are widely used in the southwestern areas of the United States, with the majority of the structures located in the Southern California area. More and more development is...

The Last Two Extreme Floods in Germany—Analyses and Consequences
The last two extreme floods in Germany occurred in December 1993/January 1994 and January 1995 within the River Rhine basin with both floods having different causes. In a comparison study,...

Flash Floods and Their Warning in Vietnam
At present, in Vietnam flash floods occur on small mountainous catchments and cause considerable damage to lives and property, to the national economy, and to the environment. The flash-flood...
