A Statistical Climate Inversion Scheme and its Application in Hydrologic Impact Assessment Studies Associated with Global Climate Variability
The use of deterministic atmospheric, general circulation models (GCM's) to understand potential global climate change under doubled CO₂ forcing...

Flash-Flood Forecasting by Using the HEC1F Model
The application of a lumped conceptual model, the well known HEC1F, for flash-flood forecasting and warning to the Venetikos river basin in Northwestern Greece, is presented. The combination...

Distribution of Flood Volumes Beyond Design Discharges
Quantitative prediction of flood volumes beyond design discharges is important for hydrologic design of river constructions, such as bridges and culverts, because these are the volumes...

Combining Orographic Precipitation and Runoff Models for Improving Reservoir Operations
This paper reports on a study being conducted by the Bureau of Reclamation whose end objectives are improved quantitative precipitation forecast (QPF) for use in hydrologic runoff models...

Travel Time in Mountain Basins
An empirical relationship is developed for estimating travel time in high gradient stream channels with natural beds of large gravel, cobbles and random boulders and which are flowing...

A Potential Problem with Mean Dimensionless Hydrographs at Ungaged Sites
A flood hydrograph for an ungaged stream site can be estimated from a mean dimensionless hydrograph and estimates of instantaneous peak discharge (Q) and total storm runoff volume (V)....

Establishment of a Habitat Monitoring Program to Assess Potential Impacts of Diversion of POTW Effluent
As part of the permitting process for a gas-fired power plant, the environmental impacts of diverting POTW effluent from the receiving water for cooling tower makeup was investigated....

RCHARC: A New Method for Physical Habitat Analysis
The Riverine Community Habitat Assessment and Restoration Concept (RCHARC) is applied to the Gavin's Point tailwater of the mainstem Missouri River as part of studies by the U.S. Army...

Minimum Streamflow for Habitat?A Case Study. Menikganga River Diversion Project?Sri Lanka
Determination of minimum streamflows to be left in the stream channel for the sustenance of the downstream habitats becomes a difficult task when quantitative requirements of such habitats...

Statistical Analysis of Extreme Hydrological Droughts
The study examined several works about extreme droughts for their validity with different parameters by the statistical experimental method. The results showed that the analytical method...

Stochastic Modeling for Drought Analysis Using Thomas-Fiering Lognormal Three Parameter Model
Three variations of Thomas-Fiering log normal 3-parameter(TFLN3) model are fitted to the unregulated south-west monsoon-dependent monthly streamflows measured at Krishnarajasagara (KRS)...

PMF Estimation for a Sparsely Gaged Watershed
This paper describes a procedure used to determine the design-basis and probable maximum flood (DBF and PMF) for Jiguey Dam located in the Dominican Republic. This dam is situated upstream...

Monongahela River Mapping & Flood Hazard Study
The study described here represents a unique collaboration and cost-sharing effort between two Federal agencies: the U.S. Army Corps of Engineers (USACE) and the Federal Emergency Management...

Development of a Raw Water Master Plan Model to Assist Long Range Drought and Water Conservation Planning for the City of Louisville, Colorado
The City of Louisville, a municipal corporation charged with meeting the water demands of almost 5,000 water accounts and faced with a diminishing supply of available senior water rights...

Lower Missouri River Water Quality Model for Evaluating Flow Alterations
A modified version of the US Environmental Protection Agency's (USEPA) one-dimensional (longitudinal) stream water quality model, QUAL2E, was applied to the lower Missouri River to evaluate...

Predicting Basin-Wide Tailwater Temperature Patterns by Combining Mechanistic and Statistical Water Quality Modeling
A simplified method for predicting water temperature patterns downstream of a peaking hydropower dam is described for the Fort Randall Dam tailwater of the mainstem Missouri River as part...

Additional Years of Record and Peak Discharge
The effect of additional years of stream gaging records is analyzed for stream gages in Nebraska. Frequency estimates are based on procedures outlined in Bulletin 17B, including skew coefficient...

Mean Areal Precipitation Estimation Using Radar
The accuracy of mean areal total storm precipitation (MAP) over small urban basins (30-100 km²) in the Denver, CO metro region was examined using...

Water Resources Management Using a Geographic Information System over a Wide Area Network
To assist in the management of water resources in the Santa Ana River Basin, in Southern California, the Bureau of Reclamation in Denver, Colorado and the Santa Ana Watershed Project Authority...

Reservoir Regulation and Real-Time Models for Trinity River Flood Prevention and Control
After unprecedented flooding from the Spring of 1989 through 1991 in the Trinity River basin, the Texas legislature allocated funds for flood related studies in Senate Bill 1543 (1991)....
