Math Modeling of Mixing Zones in River Systems
A numerical mixing zone model was developed utilizing an implicit finite difference method with a weighted numerical scheme. The model was based on the two-dimensional advection-dispersion...
Computer Aided Drafting in the Water Resources Environment
The movement from traditional mechanical drafting to computer aided drafting in the small consulting business/research environment while necessary from the viewpoint of productivity and...
Interactive simulation of Water Resource Systems
This paper outlines some of the research currently underway at Cornell aimed at the design of an interactive simulation methododology. It describes the general approach to simulation modeling,...
Management Strategy
Meanders of sinuous streams are often cut off by natural action or by man in order to improve conveyance or navigability. Cutoff bendways, as long as they remain aquatic, provide extremely...
Continuous Modelling of Downstream River Erosion Caused by 40 Years of Urbanization
The US EPA Stormwater Management Model (SWMM3) was installed on an IBM-PC compatible network. The adapted program, known as PCSWMM3, and incorporating a simple algorithm for modelling...
Water System Reliability?Balance of Cost and Risk
Reliability of water distribution systems to perform adequately during stress situations is dependent both on operation/maintenance preparedness as well as the limitations of the physical...
A Model Relating Water and Sediment Yield to Upstream Agricultural Practices
A physical-process model is formulated to quantify daily water and sediment yield as related to upstream land use, land management, and soil and water conservation measures. This model...
Ground Water Strategy in California
There is great debate over when and how much new water California needs. Yet of the backbone supply, wells that could serve over 1 million people have been either removed from use or blended...
The Role of Local Government in Water Quality Management
To meet the challenge of providing safe drinking water at a reasonable cost, local governments, together with water utilities, must do more than merely fund the implementation of state...
Advection Calculations Using Spline Schemes
The calculation of advective transport in one and two dimensions is done by the method of characteristics using spline interpolating polynomials at the forward time step. The method has...
Conjunctive Water Use Planning
The phase 'conjunctive use' refers to the integrated management of various water resources within a river basin or other geographic region. The objectives of...
A New Dam in California?Piece-of-Cake!
It initially appeared that a series of insurmountable roadblocks would prevent the City of Morro Bay from constructing a new dam and water supply reservoir on San Bernardo Creek near the...
An Optimization Model for Use in Analysis and Design of Wastewater Treatment Systems
The objective of present wastewater treatment plant design is to provide a cost effective processing system for a given waste-water. Generally each of the unit processes is designed to...
Use of Stochastic Hydrology in Reservoir Operation
The Bureau of Reclamation is incorporating stochastic traces to provide a broader basis for management decisions during drought periods for the Central Valley Project in California. A...
Ecological Impacts of Sediment Transport to Tropical Reservoirs
Sediment transport and siltation influence both the longevity and ecology of tropical reservoirs. The sediment load to these systems is typically seasonal and affects ecological processes...
Automated Control for Central Arizona Project Distribution Systems
Computer based automatic control for three extensive open channel water distribution systems is described. Radio telemetry allows a central computer to execute control logic at individual...
Geohydrologic Considerations in Ground Water Modeling
Ground water modeling is an effective engineering and management tool for evaluating complex hydrogeologic situations in a cost effective manner. Objectives of a particular study dictate...
North American Weather Modification Organizations
The objectives and purposes of most professional, technical and institutional organizations made up of people interested in weather modification as a tool in North American water resources...
Comparison of Minimum Instream Flow Needs
A sound determination of Instream Flow requirements is facilitated by the use of a physical habitat versus streamflow relationship and the analysis of instream flow benefits produced when...
Instream Flow Needs to Protect Fishery Resources
Numerous methods have been developed over the past several decades to assess the effects of flow regulation on fishery resources and to provide a basis for the determination of suitable...
