Wetland Hydrology Management in Australia
Changes to the hydrologic regime of wetlands is a vital factor affecting the natural diversity and conservation values of wetlands. The management of wetland hydrology thus forms an integral...
Hydrologic Runoff Models for the Arid Southwest United States
Recently, hydrologic study criteria manuals (or hydrology manuals) were prepared for the arid southwest regions of Clark County (Las Vegas vicinity, Nevada), Maricopa County (Phoenix vicinity,...
Flood Elevation Limits in the Rocky Mountains
An analysis of 77,987 station-years of streamflow-gaging station data from 3,748 stations in the Rocky Mountains indicates that there is a latitude-dependent elevation limit to substantial...
A Computer System to Operate Coastal Structures
The Central and Southern Florida Flood Control Project (C&SF) was designed and built by the U.S. Army Corps of Engineers and is operated and maintained by the South Florida Water...
Stochastic Modeling for Drought Analysis
Periodic as well as annual stochastic streamflow models have been fitted to the highly variable flows measured at Krishnarajasagara (KRS) on river Cauvery (Southern India), which is monsoon-dependent...
Peaks Over Threshold Model for Seasonal Flood Variations
The peaks over threshold (POT) series model has been used in hydrology to analyse extreme phenomena such as floods or precipitation amounts exceeding a certain threshold level. The results...
Robust Estimators in Hydrologic Frequency Analysis
This paper applies a specific robust estimation procedure known as 'trimming' in flood frequency analysis. The trimming technique consists in censoring the series of recorded floods by...
Incorporating GIS Technology in Standard Flood Hydrology Applications
The potential for application of Geographic Information Systems (GIS) to hydrologic analyses has received increasing attention in recent years. Published literature on hydrologic applications...
A GIS Application to Hydrology
This paper illustrates an application of Geographic Information System (GIS) in estimating input parameters for Penn State Runoff Model (PSRM), a watershed rainfall-runoff simulation model....
The Use of Geographic Information Systems and Models on Personal Computer and Workstation Platforms, in the Development of a Wellhead Protection Program, Salinas Valley, California
The Salinas Valley is located on California's Central Coast. The ground water basin supports 850,000,000 M2 of irrigated crops which have a market...
GIS Landscape?A Solution for Wellhead Protection
Wellhead protection is an emerging issue for water suppliers based largely on the 1986 Amendments to the Federal Safe Drinking Water Act (SDWA). State governments are developing wellhead...
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...
A Physically Based Methodology for Regional Flood Frequency Analysis
The problem of flood frequency estimation in ungauged catchments is approached by using statistical procedures jointly with derived distribution techniques. The application of this methodology...
Dynamic Perspective on the Capillary Barrier Effect at the Interface of an Upper Fine Layer with a Lower Coarse Layer
The theoretical principles behind the determination of infiltration rate into a coarse layer overlain by a tight layer are reviewed. As a descending unsaturated wetting front hits the...
Simulation of the Propagation of Conserevative Contamination
The hydrodynamic model of the pollutant transport in water bodies was developed and adopted for Volga water supply system of Moscow, which includes five reservoirs and a channel. The model...
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...
Muskingum Basin Reservoir Pool Frequency Analysis
The purpose of the study was to develop a consistent and defendable elevation frequency analysis of pool elevations for sixteen reservoirs within the basin. A significant level of interest...
Survey of GIS Applications in Surface Water Hydrology
Geographic information systems (GIS), computerized tools for management and manipulation of spatially referenced data, are increasingly being used for engineering analysis and design of...
An Operational GIS to Support State-Wide Hydrologic and Nonpoint Pollution Modeling
A geographic information system(GIS) that is structured for hydrologic and nonpoint pollution modeling(GISHYDRO) became operational in the Maryland State Highway Administration's Division...
New Directions in Integrated Hydrologic Modeling with GIS
In 1988, the Florida Institute of Phosphate Research funded a project to develop an integrated hydrologic model to more adequately represent mine reclamation hydrology. Five years later,...
