Lagrangian-Eulerian Approach to Modeling Contaminants
A Lagrangian-Eulerian modeling approach predicts potential contaminant distributions resulting from the disposal of sewage sludge at the Deepwater Municipal Disposal Site off the northeast...
A Unified Hydrodynamic-Water Quality Model
To understand the cause-effect relationships controlling water quality in dynamically narrow estuaries, a time dependent branching, laterally averaged (longitudinal and vertical) hydrodynamic...
NID Water Supply and Hydropower Operation Model
A basic requirement of CH2M HILL's Raw Water Master Plan for Nevada Irrigation District (NID) was to determine the dependable water supply available from the District's...
Multivariate Modeling of Hydrological Time Series for Generation of Reservoir Operating Rules
A multivariate model and a disaggregation model are used in this study to generate annual and monthly time series of streamflow data for multiple sites. The parameters of the models are...
Reservoir System Simulation Through Network Flow Programming
A generalized reservoir system simulation model that makes use of a network flow programming technique has been developed for use in planning and operation studies of multi-purpose water...
Optimal Weekly Operation of a System of Three Multipurpose Reservoirs
Marion, Council Grove, and John Redmond Lakes located in the Upper Neosho-Cottonwood River basin are an integral part of the State Water Marketing Program of Kansas. In addition to water...
Engineering and Policymaking: The Platte River in Nebraska
Substantial conflict exists over proposed water projects in the Platte River Basin of Nebraska. A computer simulation model, representing the engineering and environmental dimensions of...
Modeling to Generate Alternatives: A Review
Modeling to generate alternatives (MGA) is a species of multiobjective programming in which some relevant objectives and perhaps some constraints are deliberately left unquantified. The...
Integrating Policy Factors in Stream-Aquifer Models
One of the main issues appearing today in the field of water resources is the management of complex hydrologic systems consisting of surface streams and aquifers. The management problem...
Traveling Trickler Center Pivot Design
There have been a number of proposals to improve the center pivot irrigation system in order to overcome the inherent inefficiency from high evaporation losses and energy requirements....
Intense Storms and the Runoff Coefficient
During prolonged, intense storms the runoff coefficient increases in value and approaches one irrespective of the vegetation and soil characteristics of the watershed. As the runoff coefficient...
Unique Flood and Drainage Problems in Los Angeles
Storm drainage for the coastal cities has to traverse highly used sandy recreational beaches. Due to new requirements on the construction of storm drains to the ocean, a beach outlet has...
Feasibility Study of Flood Control for the Maumee River in Allen County, Indiana
In March, 1982 the Maumee River overtopped its banks flooding parts of the City of Fort Wayne and unincorporated areas in Allen County, Indiana. The estimated damage to the area was about...
Modification of the Step Drawdown Test for Pump Selection
This paper suggests a slightly modified mathematical model for pump tests whose aim is to design the correct pump for a well. The advantage of the model presented is that it incorporates...
A 2-D Model for the Guaiba Estuary (Brazil)
On the northeastern edge of the Guaiba is Porto Alegre, with more than 1 million inhabitants. A navigation channel through the Guaiba Estuary and the Patos Lagoon links the city to the...
Hydrodynamic Simulation of the Upper Potomac Estuary
Hydrodynamics of the upper extent of the Potomac Estuary between Indian Head and Morgantown, Md. , are simulated using a two-dimensional model. The model computes water-surface elevations...
Hydraulic Modeling for Ecological Research
Because of the problems and expenses of a continuous data collection program for large rivers, it was decided to develop an integrated hydrodynamic and biological model for the Illinois...
Organization Design of a Water Resources Institution
An overview of the field of organization design is presented along with a brief description of major macro-organization design theories. Utilizing this information, four water resources...
Effect of Baghdad City Sewage Treatment Effluents on Dissolved Oxygen Profiles of an Iraqi River
The paper presents measured dissolved oxygen (DO) profiles in an Iraqi river in the vicinity of Baghdad City. The effect of the effluent discharges from Baghdad Sewage Treatment Plant...
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...
