Issues In Managing Erosion: The Spring Timber Sale Case Study El Rito Tanger District, Carson National Forest, New Mexico, Neil W. Gray

Water Resources Professional Project Reports

The effect of logging, within the Carson National Forest in the Upper Rio Grande Basin of north central New Mexico, on soil erosion rates and downstream water quality and quantity within the acequia systems of the rios Tusas, Vallecitos and Ojo Caliente. Complicating the situation is that the Rio Tusas, of which Spring Creek is a tributary, has been identified as not meeting state water quality standards. The probable source of pollutant/threat is assessed as "rangeland agriculture" and the causes of non-support or threat status is "turbidity, siltation, reduction of riparian vegetation, streambank destabilization" (NMWQCC, 1998).

An Examination Of Gasoline Pollutants From Two-Cycle Marine Engines Within Lake Mead National Recreation Area, Brian Carter

UNLV Theses, Dissertations, Professional Papers, and Capstones

Jet skis are a very popular "toy" to have in the United States. They account for almost a third of all boat sales, and their numbers are growing rapidly. Unfortunately jet skis use two-cycle engines that pollute at unacceptable levels. Jet ski motors can emit up to 25% of its fuel right back into the water. This alarmed me and I wanted to take a deeper look into how bad jet skis pollute Las Vegas' primary water source. Lake Mead. I looked into how a two-cycle engine differs from a regular engine and I looked at the actual pollutants a …

Storm And Base Flow Water Quality For Bear, Calf, And Tomahawk Creeks, Kenneth F. Steele, David N. Mott

Arkansas Water Resources Center Technical Reports

Because of the conversion of 92,780 acres of forest to pasture land in the Buffalo River watershed over a 27 year period, there is concern about the affect of agricultural activities on the water quality of the river. Three tributaries (Bear, Calf and Tomahawk creeks) located about mid-length of the Buffalo River were chosen to investigate the affect of agricultural activity on water quality because these streams provide the greatest amounts of fecal bacteria, nitrate+nitrite and phosphorus to the river, despite comprising only 13% of the watershed.

Effect Of Parameter Distributions On Uncertainty Analysis Of Hydrologic Models, C. Thomas Haan, Daniel E. Storm, T. Al-Issa, Sandeep Prabhu, George J. Sabbagh, Dwayne R. Edwards

Biosystems and Agricultural Engineering Faculty Publications

Increasing concern about the accuracy of hydrologic and water quality models has prompted interest in procedures for evaluating the uncertainty associated with these models. If a Monte Carlo simulation is used in an uncertainty analysis, assumptions must be made relative to the probability distributions to assign to the model input parameters. Some have indicated that since these parameters can not be readily determined, uncertainty analysis is of limited value. In this article we have evaluated the impact of parameter distribution assumptions on estimates of model output uncertainty. We conclude that good estimates of the means and variances of the input …
