Organizing a Local Water Resources Technical Group
Participating in a local water resource technical group can be rewarding professionally as well as socially. However, if such a group does not exist in your area, organizing one is an...

The Birth and Success of Orange County's Hydrology and Hydraulics Technical Group
The Orange County.s Hydrology and Hydraulics Technical Group (HHTG) has been very successful ever since it was founded in 1991. The HHTG is incorporated as a Technical Group under the...

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...

Impacts of NAFTA on Environmental Engineering
This paper addresses recent developments in the environmental sector under the North American Free Trade Agreement (NAFTA). The North American Free Trade Agreement (NAFTA) represents a...

Computing Flood Damage Reduction Accomplishment
Following flood events, the damage reduced by a federal flood damage reduction project must be computed to inform the public and assist officials in making decisions. This paper will describe...

Local Sponsorship and Floodplain Management
An outline of Local sponsor for SARP and FEMA floodplain revisions....

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...

Subcatchment Parameterization for Runoff Modeling Using Digital Elevation Models
Numerical algorithms are presented to estimate the length, width and slope of rectangular planes representing irregularly shaped overland contributing areas defined on raster Digital Elevation...

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...
