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...

Wastewater Reuse: An Alternative for Potable Water
Adverse economic conditions throughout the world have resulted in a shift of priorities causing water supply and sanitation schemes to relegate down the list of adequately funded projects....

Appropriate Sanitation Technology Advisor: A Planner's Tool in Less Developed Countries
The goal of the expert system (ES) prototype described in this paper is to create an advising method for planners, engineers and officials in Less-Developed Countries (LDCs) to utilize...

Protection against Flooding: A New Delta Plan in the Netherlands
The Netherlands are situated on the delta of three of Europe's main rivers: the Rhine, the Meuse, and the Scheldt. As a result, the country has been able to develop into an important industrial...

Design Guidelines for Bioengineered Bank Stabilization
Design of bioengineered slope stabilization measures in riverine environments to minimize rates of stream bank erosion requires accounting for hydrologic, hydraulic, geomorphic, geotechnical,...

River Restoration Considerations Beyond Channel Design
Restoration of river systems in highly disturbed environments poses unique challenges beyond channel design. The Jordan Creek Restoration project in Idaho was conducted in a valley disturbed...

Results of a GIS/HEC-1 Interface Module
Great strives have been made in recent years to automate the S.C.S. curve number weighting process required for large-scale watershed modeling utilizing Geographic Information System (GIS)...

Field Verification of Dem-Derived Watershed Response
Rainfall-runoff data from an NAEW Experimental Watershed are used to test the feasibility of deriving the watershed response from the digital elevation model of the watershed. Using Clark's...

Development and Implementation of a Capital Improvement Program for a Small Water Utility
The City of Las Cruces water utilities is being exposed to accelerated population growth and is faced with inadequate capital infrastructure to meet increasing demands. The City's...

Water-Related Hazards: India's Experiences
The geographical position of India (N 8? and 37?; E 70? and 97?) and its physical features are such that a variety of climatic conditions prevail over different parts of the country. Its...

Upper Mississippi River System Environmental Management Program (EMP)
Introduction The Upper Mississippi River Navigation System (UMRNS) is one of the largest Public Works projects existing within the continental United States of America. The system, which...

Optimization Modeling of Complex Surface Water Collection Systems
The New York City (NYC) water supply system is currently being modeled using Linear Programming (LP) optimization techniques. A series of simulations were performed to investigate the...

Flood Damage Estimates Using GIS Spatial Analysis
The catastrophic flooding in the midwest during the Summer of 1993 and in California in the Spring of 1995 resulted in flood damage estimates in the hundreds of millions to billions of...

3D Flow Structures?From Laboratory to Field Applications
One laboratory experiment and one field application have been modeled. For each one different sources of errors in the model results could be detected. It may be concluded that the applicability...

Model for Water Quality in Periphery of Distribution Systems
A model is presented for water travel time and chlorine concentration in periphery dead ends of the water distribution system. The model is developed under the premise that residential...

The Management Improvement Program: An Irrigation District's Perspective of the Demonstration Program
In November 1990, the Maricopa-Stanfield Irrigation and Drainage District agreed to participate in the first application of the Management Improvement Program (MIP) for irrigated agriculture....

The Cost of Highway Bridge Scour in the State of Minnesota
Different states are faced with different conditions with respect to geology, topography, climate, native vegetation types, bridge ownership, and bridges management systems, which in turn...

Simulating DBP Precursor Transport in Sacramento Delta
Fate and movement of disinfection by-product organic precursors in California's Sacramento-San Joaquin Delta was simulated for a 365-thy period with a hydrodynamics and transport...
