Modeling Groundwater Contaminant by Unstructured FVM
This study focuses on the numerical solution of the integral form of transport equation on unstructured grids. The algorithm is developed in direct finite volume concept and constructed...

Searching for Optimal Combinations of Stormwater Detention Basins
Hydrology of urban areas is dominated by two distinct characteristics: (1) a preponderance of impervious surfaces created primarily by pavement and roofs, and (2) the presence of constructed...

Canal Control and Automation for the Central District System
The Central Nebraska Public Power and Irrigation District system provides irrigation and hydropower benefits in south-central Nebraska. Because of its complexity, the system relies heavily...

Risk-Based Planning and Management of Maintenance Dredging
The U.S. Army Corps of Engineers (Corps) Institute for Water Resources (IWR) is developing and applying a risk-based approach to address maintenance dredging cost, reliability, and budgetary...

Numerical Modeling of Water Flow over Porous Media
The momentum transport phenomena at the interface of porous media and fluid are numerically investigated. The single domain approach is used with matching boundary conditions; i.e., the...

Application of an Optical Monitor in Automatic Control of Coagulation Dosing in Water Treatment Operations
The feasibility of applying an optical monitor in the automatic control of coagulation was assessed in this study. Prior to simulation testing, a series of batch tests was performed to...

Design and Implementation of On-Farm Surface Drainage Projects in the Humid Tropics of Mexico
In the humid tropics of southeastern Mexico, the Mexican National Water Commission (CNA) has constructed a network of collector drains for stormwater runoff removal. At the same time the...

A New Strategic Management of Pumping Station in Sewer Systems
Pumping stations are literally the heart of most sewer system operations and sewage treatment plant processes. Current studies show that a small improvement of pump efficiency will offer...

CHEMFLO Modeling of Aquifer Bioremediation in Vadose Zone
This paper deals with bioremediation in the vadose zone with an emphasis on using numerical models as a tool to ensure that the concentration of nutrients is maintained at a required level....

COASTMAP: An Integrated System for Environmental Monitoring, Modeling and Management
The development of COASTMAP, an integrated system for environmental monitoring, modeling and management for fresh and marine waters, is presented. The system allows the user to collect,...

Overview of DoD Research in Groundwater Modeling
The U.S. Army Engineer Waterways Experiment Station leads a multi-agency research program for the Department of Defense (DoD) which continues the development of integrated, comprehensive...

Computational Tools for Subsurface Conceptualization
Development of subsurface conceptual models for use in groundwater flow and transport modeling requires that existing data in the form of boring logs, cone penetrometer (CPT) logs, geophysical...

The DOD Groundwater Modeling System: A Conceptual Model Approach
A suite of new simulation tools have been developed in the version 2.0 of the Department of Defense Groundwater Modeling System (GMS). These add considerable complexity to the GMS which...

Ecological and Biological Considerations in River Restoration
When planning river restoration projects, proper consideration must be given to the target resources of concern. This should include provisions to meet the physical, hydraulic, and biological...

Developing Parameters for a Quasi-Distributed Runoff Model Using GIS
The widespread availability of radar precipitation data is driving rainfall-runoff modeling from lumped-input to distributed-input methods. As a consequence, model parameterization is...

A System Approach for Identifying and Improving Hydraulic Numerical Modeling Reliability
A system response approach which uses Fourier transform through a multiple-input/ single-output (MISO) nonlinear system to evaluate the model performance of verification and simulation...

Hydrodynamic Changes Associated with Navigation Traffic on the Upper Mississippi River System
Research has been conducted at the Illinois State Water Survey for the last five to seven years to collect field data from the Illinois and Mississippi Rivers to determine the extent and...

Spatial Statistics for Rainfall Forecasts Assessment
Assessments of rainfall forecasts were developed using GIS-based spatial statistical procedures applied to calibrated radar-rainfall fields in central Oklahoma. The overall objective of...

Automated Tools for Spatially Distributed Rainfall/Runoff Modeling
A watershed modeling system (WMS) has been developed to address the needs of surface water rainfall/runoff computer simulations. WMS, developed at the Engineering Computer Graphics Laboratory...

Status Report ? Task Committee on GIS Models and Distributed Models of the Watershed
In recognition of the trend toward the adoption of geographic information system (GIS) technology in analyzing hydrologic problems and the obvious applications of GIS in incorporating...
