A Long-term Perspective on Drought in the Great Plains and West
Management of water resources requires an understanding of the full range of natural variability and its consequences. The weather record, which spans the last 100 years or so, provides a snapshot of the contemporary history of drought and its... 2006-11-29

Instream Flow Legislation
In the west, state law historically considered water left in the stream to be wasted. Western states, which rely heavily on diversions to meet their water needs, have encouraged full appropriation of rivers and streams. In many cases, however,... 2006-11-29

Price elasticity reconsidered: Panel estimation of an agricultural water demand function
Using panel data from a period of water rate reform, this paper estimates the price elasticity of irrigation water demand. Price elasticity is decomposed into the direct effect of water management and the indirect effect of water price on choice... 2006-09-19

The Public Interest Test for Water Appropriations
Nebraska, like most states, imposes a “public interest” review on applications for water appropriations, changes and transfers. However, Nebraska statutes do not provide any specific public interest criteria for use in evaluating applications for... 2006-11-29

Atrazine in a Stream-Aquifer System: Transport of Atrazine and Its Environmental Impact...
The municipal wellfield for Lincoln, Nebraska, consists of 44 wells located adjacent to the Platte River near Ashland, Nebraska. The herbicide atrazine was monitored in the river and two transects of monitoring wells. The amount of atrazine... 1993-01-01

The Republican, the Platte and Pumpkin Creek: Current Nebraska Water Policy Issues
Potential conflicts between surface water users and ground water users are posing perplexing challenges to Nebraska policy makers. Surface water law is the rule of priority, "first in time is first in right," as administered by the Nebraska... 2006-11-29

Water as Property
The issue of whether water is or should be characterized as property under the law raises considerable controversy. In the western United States, water is typically viewed as a form of property, while in the east it is not. Whether water should be... 2006-11-29

Transformation of Hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) by Permanganate
The chemical oxidant permanganate (MnO4−) has been shown to effectively transform hexa-hydro-1,3,5-trinitro-1,3,5-triazine (RDX) at both the laboratory and fieldscales. We treated RDX with MnO4− with the objective of quantifying the effects of pH... 2011-03-31
