Underground Drainage of Urban Runoff from Natural Depressions
A unique subsurface system was designed and implemented for draining such a natural depression in the City of West Lake Hills, Texas. This subsurface drainage system uses a part of the...
Evaluation of Stormwater Management Structures in Maryland Proportioned by SCS TR-55
Various state and local agencies in Maryland are requiring that the Soil Conservation Service Technical Release 55 be used to evaluate impact of urbanization on peak rates of discharge....
Design Criteria for Detention Basins in Urban Drainage
Many communities require the use of detention basins in order to manage the increased runoff discharge in all newly developing watersheds. The authors have shown earlier that the typical...
Detention Basin Design Using Continuous Simulation
A continuous simulation model is proposed for use in the design of detention basins. The model accepts standard National Weather Service hourly rainfall data as input. The hourly rainfall...
The Storage Matching Technique of Detention Basin Design
In recent years, use of continuous rainfall - runoff simulation with historic rainfall data has become much more popular for the design of detention basins and reservoirs. While it may...
Seasonal Rule Curve Reservoir Operation
This paper addresses the potential for increasing the beneficial use of existing reservoirs in the state of Texas through seasonal rule curve release policies. Seasonally varying operating...
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...
