Hydraulics of Enlarging Cannonsville Reservoir
This paper describes the hydraulic studies performed for enlarging the Cannonsville Reservoir with a gate system which could raise the normal storage level without having an adverse effect...
A Probabilistic Method for Determination of the Required Capacity of Reservoirs
Evaluation of water supply potential of multi-purpose dams generally involves determination of the required capacity of reservoirs for new dams and analysis of safe yield or reliable yield...
Minimizing the Impact of Salinity Intrusion Due to Sea Level Rise
A rise in sea level will cause saline water to intrude up estuaries including those adjacent to aquifers with major pumping centers. During a drought a significant amount of saline estuary...
Transport Model for Aquifer Reclamation Management
A contaminant transport model which is specifically designed for management applications is developed. A key feature is the transient velocity field needed in the solution of the advection-dispersion...
Modeling Coal Pile Leachate - A Case Study
Ground water transport of coal leachate from an existing unlined coal storage pile was modeled using the USGS 'Computer Model of Two-Dimensional Solute Transport and Dispersion...
Groundwater Quality Modeling at Redlands/Crafton Area
Organic groundwater contamination exists in the Redlands area of the Bunker Hill Groundwater Basin which is of major concern to the health and water agencies in the region. The contaminants...
An Application of EPA EXTRAN Model to a Flood Management Study in South Florida
In performing the flood management studies, somewhat unique concerns in South Florida are the backwater conditions due to tidal or non-tidal tailwater, flow reversals from project canal...
Multiple Parameter Rule Curve for Reservoir Operations
A procedure for deriving operations rules for water supply storage in a multipurpose reservoir, based on physical principles and data analysis, is described. This procedure has several...
A Riverflow-Water Quality Control Model
In order to implement how regulated riverflow (control variable) impacts the salinity (output variable) under a tidal dynamic environment, a multiple input control system is developed....
ESOLIN: A Model to Optimize Water Resource Systems
ESOLIN is a simulation model designed to study and optimize the development and operation of large hydro resource schemes. It was developed as a tool for the development of large hydro...
Effects of Data Extension on Drought Probabilities
A condensed-parameter disaggregation model was applied to the monthly streamflow records on two rivers in Idaho, to investigate the occurrence and probabilities of drought periods. Using...
The GEV Distribution in Drought Frequency Analysis
Three decades have passed since A. F. Jenkinson found the general solution to the Stability Postulate, which is the condition that all the extremes must meet, and after him that solution...
Deriving Streamflow Distribution Probabilities
Streamflow distribution probabilities are often involved in the stochastic analysis of water resources systems. Limited by data availability, certain probability terms can hardly be abstracted...
Muskingum Flow Routing Using Personal Computers
The paper discusses how tedious computations involved in flow routing can be easily implemented on Personal Computers. Parameter estimation and routing calculations for both linear and...
A Hybrid Model for Storage Routing Through Rock Dumps
Construction of permeable structures across stream channels results in temporary impoundment of flood waters upstream of such structures. This happens because the hydraulic conveyance...
Analysis of Drought Indicators
The Pennsylvania Department of Environmental Resources currently monitors five parameters in its regional water supply management program. These are: (1) accumulated precipitation deficit;...
Drought Analysis in the Ohio River Basin
This study formulates the drought series, including drought occurrence time, duration, and deficit volume by the use of daily streamflows and a tracer level of one-half mean value. The...
Mapping of Drought Status in South Florida
The Water Management District (the District) sets regulations to guide water users in conservation of water use in four phases of drought severity. The District's Governing Board is responsible...
Southeastern Drought of 1986 - Lessons Learned
An interim drought management plan for the Apalachicola-Chattahoochee-Flint (A-C-F) river basin was completed in April, 1985, just in time for testing as the drought developed. Objectives...
Results of a Regional Synthetic Unit Hydrograph Study
Selected results of a regional synthetic unit hydrograph study are presented. Using the gamma function to approximate the SCS curvilinear unit hydrograph, peak rate factors were determined...
