A GIS Sewer Database for a University Campus
The development of a geographic information system (GIS) based sewer network database for the Purdue University campus in West Lafayette, Indiana, is discussed in this paper. The database,...
Non-Federal Flood Control Works Inspection Program
This paper presents a general description of the Non-Federal FCW Inspection Program and results obtained from the evaluations already completed. A discussion of the GIS package for data...
Evaluation of System Downstream Control
System downstream control (SDC) has been developed to optimally and automaticaly control canal systems. The objective of system downstream control is to maintain a reference water depth...
Flood Control in the Brazilian Electric System Reservoirs at Parana River Basin
This paper describes the experience of the Brazilian Electric System in flood control at Parana River basin, and presents the factors that required the consideration of flood impacts in...
Engineering Aspects of Wetland Mitigation
Wetland mitigation demands a multi-disciplinary engineering approach, and a systematic collection, evaluation and analysis of data. The design of a constructed wetland addresses these...
Direct Sizing of Small Stormwater Pump Stations
Pump stations are components of stormwater drainage systems that remove collected storm runoff from locations where drainage by gravity is not feasible. Usually pump stations will operate...
Development of the San Joaquin County Hydrology Manual
A hydrology manual was prepared for the County of San Joaquin, California for the determination of storm runoff quantities for the design of flood management facilities, floodplain analysis,...
Sediment Impacts on Yield from a Two-Reservoir System in Puerto Rico
The Dos Bocas and Caonillas reservoirs in Puerto Rico are being considered for conversion from hydroelectric to water supply operation. Both reservoirs are approximately 50 years old and...
US/Mexico Border Drinking Water Study
This report is an outgrowth of a more detailed report, written as part of an Environmental Protection Agency (EPA) study. This report represents my views, and does not necessarily represent...
Emerging Concepts for Management of Salinity and Drainage in Irrigated Regions
The purpose of this paper is to very briefly highlight some physical and design concepts important to management of salinity and drainage in irrigated regions in an environmentally sensitive...
Shallow Ground Water Management with a Modified Subsurface Drainage System
An existing subsurface drainage system was modified to control the flow from the drain laterals and to control the water table depth on a portion of the field. Tomatoes and cotton have...
Efficiencies of Drainage Systems and Improved Water Management
Drainage of agricultural lands has become a contentious issue as concern increases over the actual economic benefits of subsurface drainage in irrigated regions relative to the impacts...
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...
