Financing Transit: Benefit Assessment in Los Angeles
The Southern California Rapid Transit District (SCRTD) has successfully used benefit assessment to fund a portion of the Los Angeles subway project and to provide the critical private...

The Extension of the Docklands Light Railway
The Docklands Light Railway is a publicly funded automated light rapid transit system that was opened in 1987, linking the fringe of the financial district of the City of London to an...

Public/Private Partnership for Development of the South Brunswick Station
Because of projections for continued residential and commercial growth and a large gap between stations, NJ TRANSIT decided to construct a new station in the Township of South Brunswick....

The Chicago-Kansas City Tollway: Lessons for Future Projects and Policy
The paper discusses an innovative mixed public-private financing plan and implementation plan for an investor-owned toll road connecting Chicago and Kansas City. The two plans utilize...

Assessing Nonpoint Pollution Potential of Surface Waters Using a Geographic Information System
The use of Geographic Information Systems (GIS) to determine the susceptibility of surface waters to nonpoint pollution is described. The Geographic Resources Analysis Support System (GRASS)...

Utility of a GIS in Watershed Management?A Case Study
A geographic information system data base was established for a small watershed in Shelby County, Tennessee, for both surface and subsurface water attributes. The surface water portion...

An Integrated GIS and Model for Assisting the Managers of an Army Training Area
The ARC/INFO geographic information system (GIS) has been combined with the ARX spatial expert system and the SMSP soil moisture-soil strength model to assist the managers of a major training...

Effects of Water Erosion Processes on Drainage and Irrigation Systems
This study examines the relationship between geomorphic processes and drainage/irrigation projects. It illustrates the method of geomorphic analysis by the study of a drainage project...

Biodiversity in Riparian Communities and Watershed Management
Riparian communities are demonstrated to be regional centers of biodiversity and biomass. Examples are taken primarily from bird and lizard communities in the Southwest, since these vertebrates...

Sprinkler System Design for Frost Protection
Both undertree and overtree systems for frost protection by sprinkling are currently being used. The criteria based on experimental results and theoretical modeling have been reviewed...

Rehabilitation and Modernization of Irrigation Projects is Often a Cover-up for Poor Quality Construction and Maintenance
Decreasing land and water resources available for irrigation projects is placing greater empasis on rehabilitation and modernization of irrigation projects. Inferior quality of the initial...

Understanding Delivery Performance Before Rehabilitation
In the initial stages of project formulation, decisions are made regarding the method for allocating water, and the method for physically distributing water. Any major rehabilitation effort...

Upgrading of the Orange Cove Irrigation District Water Distribution System
The Orange Cove Irrigation District covers about 28,000 Acres in the Central Valley of California. It is supplied from the Friant-Kern Canal. A semi-closed low pressure pipeline system...

Performance Measures for Irrigation Water Delivery
Performance measures are developed which facilitate analysis of irrigation water delivery systems in light of the objectives of adequacy, efficiency, dependability and equity and of water...

Canal Automation for Flexibility on Sloping Canals
This project and tested a method which would allow flexible water deliveries from medium-large canals. The canal gate movement algorithm CARDD (Canal Automation for Rapid Demand Deliveries)...

Clean vs. Dirty Water Effects in Irrigation Systems
Seepage losses in irrigation systems may be significantly affected by the suspended solids concentrations of the water. Low-solids clean water increases losses; high-solids dirty water...

Application of Neutron Soil Surface Water Monitoring for Plant Establishment
Soil surface water content measurements are tedious and time consuming, and to improve on such tasks, a neutron surface moisture probe was modified by using cadmium shielding. This prevented...

Simple Water Measuring Device for On Farm Irrigation Evaluation
Laboratory experiments were conducted for the calibration of three flumes of different sizes. The logarithmic transformation in linear regression yielded excellent results for the stage-discharge...

Delivering Appropriate Quantities of Water to the Farm
To study how well an irrigation district was able to meet farmer demand, water deliveries along two monitored lateral canals were compared to the orders and bills for these events. The...

Evaluating Groundwater Pollution Potential Using Geographical Information Systems
A procedure for developing groundwater pollution potential maps using a geographical information system (GIS) is introduced. The concept of pollution potential mapping is discussed, along...
