Coho Salmon and Water Management in the Klamath Basin 6

The purpose of this chapter is to assist the broadest possible readership in understanding the ongoing controversy regarding the stipulation of minimum flows in the lower Klamath River between April and September 2001 to protect threatened coho salmon. It is not intended to be an evaluation of the National Marine Fisheries Service’s (NMFS) Biological Opinion (BiOp) on Klamath Basin coho salmon....

Herbicides in ground water beneath Nebraska's Management Systems Evaluation Area.

Profiles of ground water pesticide concentrations beneath the Nebraska Management Systems Evaluation Area (MSEA) describe the effect of 20 yr of pesticide usage on ground water in the central Platte Valley of Nebraska. During the 6-yr (1991-1996) study, 14 pesticides and their transformation products were detected in 7848 ground water samples from the unconfined water table aquifer. Triazine an...

Land Subsidence and Fissuring Due to Ground Water Withdrawal in Yazd-Ardakan Basin, Central Iran

The Yazd-Ardakan basin in Central Iran has two separated aquifers. The shallow unconfined aquifer is supplies 40 Qanats. The deep saturated confined aquifer is the main water storage. Due to over-withdrawal, water table has been decreasing during last 25 years. Recent study shows that the shortage of the aquifer is about 16 meters and land subsidence is 0.5 1.2 meters. Long deep cracks are foun...

Geomorphological and Geo-Electrical Investigations for Ground Water Resources in Pulang River Basin, Andhra Pradesh

An endeavour is made in the present study to identify the groundwater potential zones in the Pulang River basin, Cuddapah district based on the Geological and Geo-electrical investigations. The Geomorphological features and lineament patterns are also studied in locating favourable sites for groundwater. The Geoelectrical soundings conducted at hundred locations in the basin area are interprete...
