Feasibility of Weather Modification for California's State Water Project
The California Department of Water Resources (DWR), in the mid 1950's, contracted with some 30 water agencies to eventually furnish about 4. 2 million acre-feet (MAF) of water...
Evaluation of Basin-Furrow Irrigation Systems
The division of the total flow into basin-furrows is analyzed using both energy and momentum principles. A zero-inertia model is applied to simulate the advance phase using different infiltration...
The Great Lakes Large Basin Runoff Model
The Great Lakes Environmental Research Laboratory (GLERL) developed its Large Basin Runoff Model (LBRM) specifically for modeling runoff and moisture storages in the large river basins...
Optimizing a Minimum Instream Flowby
The Commonwealth of Virginia is currently investigating methods to establish minimum instream flow requirements which may be applied to flow allocations statewide. The Crump Creek Reservoir...
Theory for Development of the TR-55 Tabular Hydrograph Method
Technical Release No. 55 (TR-55), 'Urban Hydrology for Small Watersheds,' was originally developed by the United States Soil Conservation Service (SCS) in the...
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...
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...
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...
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...
Sedimentation Impacts on a Pumpback Storage Facility
Concern over future sedimentation impacts at a proposed pump storage hydroelectric facility at Lake Francis Case on the Missouri River led to use of a numerical model to analyze lake hydrodynamics....
Nonlinear Axisymmetric Uplift of Circular Plates
A formulation of a method of analysis of the nonlinear axisymmetric response of the bottom plate of a liquid storage tank under uplifting forces is presented. At first, the plate is assumed...
Stability of Cylindrical Shells With and Without Cutouts and Subjected to Wind Load
The cylindrical storage tanks with and without cutouts are analyzed using nonlinear finite element analysis. All the cylinders are fixed at the base. Two types of cylindrical tanks without...
Detecting Underground Piping Leaks
Most leaks from underground liquid storage systems occur in the piping rather than the tank itself. The piping system is the most vulnerable component of the system, requiring great care...
Sewers Get a Breath of Fresh Air
Domestic sewage pump stations and treatment facilities have long been plagued by corrosion and odor problems caused by hydrogen sulfide. It is also extremely toxic. Sulfide production...
Harbor Revived
In Racine, Wis., officials' plans to turn a defunct commercial harbor into a recreational boaters' paradise have signaled an economic turn-around for a depressed...
