Development Of Membrane Film Fiber Optic Based Sensors For The Remote Monitoring Of The Quality Of Surface And Groundwater, Leonidas G. Bachas
Development Of Membrane Film Fiber Optic Based Sensors For The Remote Monitoring Of The Quality Of Surface And Groundwater, Leonidas G. Bachas
KWRRI Research Reports
The objective of this study was the development of chromo- and fluoroionophores and their subsequent use in sensors capable of surface and groundwater monitoring. Several reagents (modified crown ethers and porphyrins) were synthesized based on principles of chemical recognition and used for metal and pH sensing. The modified crown ether reagents include a chromogenic or fluorogenic group. The selectivity of these reagents is controlled by the size of the crown ether ring and the type of the chromogenic or fluorogenic side-arm. In addition, a fluorogenic crown ether was synthesized that incorporates a fluorogenic side-arm and a perfluorinated carbon chain. The …

Gis Characterization Of Beaver Watershed, H. D. Scott, J. M. Mckimmey
Technical Reports
Beaver Reservoir watershed is located in Northwest Arkansas including portions of Madison, Washington, Benton, Carroll, Franklin and Crawford counties. This watershed is important to the Northwest Arkansas region because it supplies most of the drinking water for the major towns and cities, and several rural water systems. The watershed consists of 308,971 ha with elevations ranging from approximately 341 m to 731 m above mean sea level. It includes the Springfield Plateau and the Boston Mountains provinces within the Ozark Plateau physiographic region. There are approximately 581 km of streams, 532 km of shore line, and 3712 km of roads …

Groundwater Investigations In The Jerramungup Shire, S B. Martin
Resource management technical reports
Drilling was carried out with a dry rotary auger rig, with a depth limit of 31 m for the first 28 piezometers and 40 m thereafter. Farmers assisted in the site selection and construction of the piezometers in most cases and will in the future be responsible for monitoring their piezometer(s) regularly. The average depth to bedrock was 18 m and the average dept to groundwater was 9 m, with an average salinity level of 3600 mS/m. The average total salt storage was approximately 2800 tonnes per hectare.
