Irrigation Hydrology: Crossing Scales
Hydrology is the science concerned with distribution, circulation, and properties of water of the earth and its atmosphere, across the full range of time and space scales. Subject matter...

Integrated Water Management for the 21st Century: Problems and Solutions
Most of the projected global population increases will take place in third world countries that already suffer from water, food, and health problems. Increasingly, the various water uses...

A Paradigm Shift in Irrigation Management
In coming decades, irrigated agriculture will be called upon to produce up to two thirds of the increased food supply needed by an expanding world population. But the increasing dependence...

Water Quality Aspects of Irrigation and Drainage: Past History and Future Challenges for Civil Engineers
This paper presents a brief history of irrigation and drainage related to ASCE activities on its Jubilee. This paper discussed legislation and policies that affect irrigation and drainage...

Review of Stabilization of Clays and Expansive Soils in Pavements and Lightly Loaded Structures�History, Practice, and Future
Expansive clay soils�those that change significantly in volume with changes in water content�are the cause of distortions to structures that cost taxpayers several billion dollars annually...

Unleashing the Flow
A 70-year-old, two-lane roadway that stretches from Miami to Tamp Bay is impeding the flow of water through the Everglades. By studying eight possible solutions in detail, engineers determined...

Assessing Long-Term Pollutant Concentration Trends in Urban Runoff for TMDL Planning and Regulatory Assessment
Loads of some pollutants in many urban watersheds include a substantial component originating with non-point sources and stormwater runoff. TMDL planning includes estimating those loads,...

Assessment of Water Quality Monitoring Sites by an Optimization Method
Allocation of sampling sites is the initial and the most crucial step of the water quality monitoring network design and redesign process. Several different approaches have been used within...

A Dynamic Climate Downscaling Prediction System for N.E. Brazil
The International Research Institute for climate prediction (IRI) is collaborating with several levels of government and various local and foreign researchers in several key disciplines...

Impact of Ground Water Management on the Hydropattern of Wetlands
In this paper, we examine the effect of altering the pumping rates of a large municipal well field, on the hydropattern of the near by PENSUCO wetland. A flow model developed earlier using...

Leakage Control?Finding a New Resource from the Existing One
It is estimated that by the year 2005, one person in two will have an insufficient supply of one of the world's most precious elements: water. Worse still, it is predicted that this shortage...

Practical Groundwater and Conjunctive Water Optimization
The Simulation/Optimization MOdeling System (SOMOS) makes it easy to do groundwater optimization modeling for a variety of scales and situations. The SOMOA module uses analytical equations,...

Rate of Under-Registration Due to Failures of Large Meters
Leaks and meter under registrations are suspected as primary components of unaccounted-for water in Korea. In 2001, national unaccounted-for-water rate is reported as 26.6%. More than...

Transparency and Integrity in Water Management
The purpose of this Paper will be to explore, define and discuss the matter of transparency, integrity and effectiveness in water and associated land management. In view of the complex...

A Decision Support System for Drought Management Planning
Traditional drought management planning has focused on curtailment of demand by instituting voluntary or mandatory restrictions on water consumption when regional hydroclimatic indicators...

How Should the U.S. and Mexico Manage Their Transboundary Water Quality?
The purpose of this workshop is to discuss with ASCE members the progress in developing a Standards document and Management Plan document associated with water quality management across...

Overall EWRI/ASCE Standards Process
The American Society of Civil Engineers is an ANSI-accredited standards development organization (SDO) and as such develops consensus-based standards in a wide-range of technical areas...

Thermal Cyclone Washing for Remediation of Petroleum Contaminated Soils
Thermal Cyclone Washing (TCW) is a soil remediation technology developed and tested at the University of Alabama in Huntsville. TCW is a combination of thermal, chemical, and physical...

Decision Support System for Daily Real-Time Operations in the Geum River Basin, Korea
A joint international collaboration between the Korea Water Resources Corporation (KOWACO) and Colorado State University (CSU) has resulted in development of a decision support system...

The Accuracy of Extrapolated Design Estimates with Hydrologic and Environmental Models
Extrapolation error in water resources and environmental modeling has not been the subject of adequate study in the past. In research and design, estimates obtained from regression models...
