Significance of Lateral Elevation Gradients in Tidally Affected Tributaries

Distributed Parameter Hydrologic Modeling and NEXRAD for River Forecasting: Scale Issues Facing the National Weather Service
With the advent of NEXRAD (Next Generation RADar), the National Weather Service has the opportunity to move from current lumped parameter modeling to more of a distributed parameter hydrologic...

Spatial Spring Runoff Modeling in a River Basin for Purpose of Forecasting

Bird Use of an Evaporation Basin and a Mitigation Wetland
A 58-ha freshwater wetland was constructed to mitigate for decreased avian reproductive success and survivorship caused by a 296-ha selenium contaminated evaporation basin. To decrease...

Fluidized Bed Denitrification of Secondary Effluent during Wastewater Reclamation in Southern California
A pilot scale fluidized bed denitrification bioreactor was operated for a period of three years as one unit process in a series designed to repurify secondary effluent for subsequent indirect...

Evaluation of Modelling Needs for Central Valley Project Operations
The Bureau of Reclamations Central Valley Operations Office (CVO) has responsibility for planning, implementing, overseeing, and coordinating the various operations of the Central Valley...

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...

CSO Planning Model Development and Verification Strategy
A model verification technique is described that uses modeled and monitored overflow occurrences defined in terms of the same long-term frequency statistics that are used to evaluate CSO...

Indianapolis Uses New Radar Technology to Refine Hyetographs for CSO Model and SSES Studies
Indianapolis is the first city in the country to install the French-developed technology designed by urban hydrologists to accurately measure rainfall between rain gauges. Installed in...

Infiltration Properties at Two Sites in the Konza Prairie
The spatial variability of soil hydraulic properties that govern infiltration were investigated at a pristine site and an agricultural site in the Konza Prairie Research Area of east-central...

Aquifer Transmissivity Computations Based on Data from Pump-and-Treat Facilities
Contamination from petroleum hydrocarbons spilled from USTs is a concern in urban areas that depend on shallow unconfined aquifers for their water supply. Studies on the transmissivity...

Modeling Climate Change Impacts on Water Resources
As part of the Electric Power Research Institute's (EPRI) comprehensive evaluation of the economic effects of climate change in the United States, we have developed methods...

Optimization and Simulation in Design and Operation of Reservoirs
Due to stochastic nature of rivers, their volumetric yields are random variables. Spatial and temporal redistribution of Water makes the reservoir construction a must. Therefore, water...

Engineering Aspects of Wetland Mitigation
Wetland mitigation demands a multi-disciplinary engineering approach, and a systematic collection, evaluation and analysis of data. The design of a constructed wetland addresses these...

Expected Moments Alogrithms for Flood Frequency Analysis
The Expected Moments Algorithm (EMA) is a new but conceptually simple approach for the treatment of nontraditional data in flood frequency analysis. Nontraditional data includes censored...
