1987-88 Actions on El Paso vs. New Mexico
It has been determined by the City of El Paso that water wells near the Texas-New Mexico borders should be used to supplement their water supply in the years 2000-2020. Opposition to the...

Wetland Impacts of Center Pivots in Wheeler Co., NE
This paper describes an investigation of wetlands impacts from an intensive center-pivot irrigation operation in a 17,000 acre portion of Nebraska's Sandhills region. Well...

Microcomputer Capability: Practitioners' Perspective
Leading practitioners in the water resources engineering field want new graduates who are well grounded in fundamentals and are computer literate. The needs of leading practitioners are...

Gas Transfer at the Water Surface: Measurements of Gas Concentration Fluctuations
The paper describes measurements of fluctuating gas (oxygen) concentrations by means of a polarographic microscope near the air-water interface. The objective is to demonstrate the feasibility...

Jet Grouting: The Pace Quickens
Over the past year, use of jet grouting in the U.S. has nearly quadrupled. A versatile tool, it has performed well in settings as diverse as a railway tunnel, industrial waste site and...

Recovery Efficiency From Single-Well Injection/Recovery Tests in a Limestone Aquifer of High Secondary Porosity
An analytical advection-diffusion model was developed to assess the feasibility of injecting and recovering water in a limestone aquifer of high secondary porosity. The model was calibrated...

Ground Water Recharge Through Wells
Surface runoff water accumulates in natural depressions called playas on the Southern High Plains; most of it is wasted by evaporation. The water is turbid, but otherwise of good quality...

Subsurface Injection of Storm Water Runoff into an Underground Storage of Bangkok
Subsurface injection through a well into sand and gravel formations of the Bangkok aquifer of untreated canal water whose composition considered similar to that of storm water runoff,...

Tucson Recharge with Existing Potable Water System
In 1987, a study was undertaken to evaluate the potential for using the City of Tucson's existing potable water distribution system and production wells for recharge of treated...

Performance of an Artesian Glacial Drift Aquifer with Induced Recharge
The City of Kalamazoo, Michigan, has constructed induced recharge facilities at sites of several of its twenty-one well fields as part of a program for supplying potable water to Kalamazoo...

Optimizing Limited Water Resources Through Conjunctive Use
The City of Santa Barbara is faced with potential water supply deficiency caused by decreasing supplies and a mild increase in demand. This paper discusses some of the results of a study...

Artificial Recharge to the Floridan Aquifer System, Orlando Area, Central Florida
Approximately 400 drainage wells exist in Orange County, central Florida. The rate of recharge through drainage wells is limited by the rate of surface flow to the wells; the hydraulic...

Ground Water Monitoring for Resource Management
Management of the ground water resources provided by the multi-layered aquifers underlying Orange County, California has required a new approach to ground water monitoring. The Orange...

Infiltration Wells in the Lakes Around the Future Markerwaard Polder
Drainage and reclamation of the Markerwaard polder in the Netherlands may cause damage to buildings and infrastructure in the eastern part of North-Holland because of subsidence. Drawdown...

Evaluating Potential Artificial Recharge Projects
The success of an artificial recharge project can be directly tied to the quality of planning of the potential projects and/or sites. The paper's purpose is to identify the...

Techniques for Delineating Subsurface Organic Contamination: A Case Study
Selection of techniques to detect and map subsurface organic contamination depends on the type of source, contamination, and hydrogeologic setting. Ideally, an investigator, manager, or...

Best Management Practices for Point and Nonpoint Sources of Groundwater Contamination
Management strategies have included regulations to guide or limit development in aquifer recharge areas and in the capture zones of public wellfields, engineering requirements to minimize...

The Delineation and Management of Wellhead Protection Areas
The delineation and protection of a management zone around specific wells or wellfields will undoubtedly become more common as the 1986 Amendments to the Safe Drinking Water Act are implemented...

Restoring Chesapeake Bay Living Resources
Following nearly ten years of study and analysis of the degraded Chesapeake Bay ecosystem, a new emphasis has emerged in 1986 - linkage of water quality to living resource problems, with...

Satellite-Tracked Buoy Activities in Saudi Arabia
During the pollution threat on the Gulf caused by the collapse of the NOWRUZ oil field well in February 1983, the Meteorology and Environmental Administration (MEPA) established an Oil...
