Selection of Sediment Transport Relations Part III: Numerical Ranking of Sediment Transport Relations
The emphasis of this paper is the methodology for the selection of sediment transport relations and is applicable for analysis of any sediment transport relation. However, to illustrate...

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...

Improving the Speed of Double Lockages
The size of tug and barge combinations on the Upper Mississippi River and Illinois Waterway frequently exceed the dimensions of the lock chambers they must pass through. The locks on these...

The Sawmill Creek Watershed Restoration Project
The Sawmill Creek project is a comprehensive watershed restoration effort. The goal is to demonstrate that existing programs can be coordinated in order to improve water quality, and habitat...

Are Erosion Control Programs Reducing Sedimentation?
In the Midwest, the USEPA National Watershed Monitoring Program is determining the effectiveness of land management strategies to improve water quality and biological diversity. The illinois...

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...

Distributed Hydrologic Modeling of Humid Regions
Distributed physically-based hydrologic modeling of humid watersheds with shallow soils is complicated by non-Hortonian runoff production mechanisms. This paper presents a numerical experimental...

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...

The Case for Water Markets as the Best Means for Effective Water Allocation
Water markets have a potential for providing flexible and efficient mechanisms for allocating water among alternative uses. In order for markets to emerge It is necessary for private rights...

ASCE Regulated Riparian Code and Florida's Regulated Riparian Experience: The Role for Voluntary Reallocation
The American Society of Civil Engineers (ASCE) model state water code for states under riparian common law offers a comprehensive administrative permitting process for allocating water...

The Case Against Markets
Markets are much in vogue as ideal institutions for managing water both nationally and internationally. True markets, however, have seldom existed for water rights and there are good reasons...

Recreational Impoundments Retrofit of Existing and Design of New Facilities
Water has been a critical component of most human endeavors, and its value as a recreational amenity is well-known. An increasing number of recreational impoundments are being considered...

Construction of Performance Contours on the Storage-Yield Plane of a Within-Year Reservoir System
The reservoir storage-reliability-yield (S-R-Y) relationships developed in the past have considered only the probability of failure to meet the target requirements, but not the likely...

Water Use Recession in San Diego Region
Water use in the San Diego region was studied using historical records collected over a period of a half century. The results indicated that the water use in this region was historically...

A Practical Approach to Watershed Sanitary Surveys
A step-by-step approach for conducting watershed sanitary surveys can be successfully applied to watersheds of all sizes. The approach involves preparing a watershed map, contacting regulatory...

Better Management in the Water Supply Sector Through Indigenous Institutions
The following discussion briefly explores how improved institutional performance in Africa's water sector can be promoted through reconciliation of indigenous and formal institutions....

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...

Design Guidelines for UV Disinfection Facilities
Current design methods for UV disinfection facilities depend largely on experience with minimum input design variables, such as water UV transmittance and required disinfection efficiency....

Numerical Modeling of Flows in Ultraviolet Disinfection Channels
Current design methods for UV disinfection facilities depend largely on experience with minimum input design variables, such as water UV transmittance and required disinfection efficiency....
