Water: US Strategic Response to Conflicts Over a Finite Resource 25-Feb-2009 39 pages
Authors:  Theodore W Munchmeyer; ARMY WAR COLL CARLISLE BARRACKS PA
The full text of this report is available for sale.Useable water is a limited commodity needed to sustain life. Nations throughout history have threatened the use of force on each other over access, quality and the quantities drawn from shrinking available sources. Many current publications argue future wars will result not from access to oil, but from disagreements on finite water resources. However, despite the rhetoric, few if any conflicts can be considered the sole reason for nations to ...

Sampling and Mapping Soil Erosion Cover Factor for Fort Richardson, Alaska. Integrating Stratification and an Up-Scaling Method MAR 2006 34 pages
Authors:  Guangxing Wang; George Gertner; Alan B. Anderson; Heidi Howard; ENGINEER RESEARCH AND DEVELOPMENT CENTER CHAMPAIGN IL CONSTRUCTION ENGINEERING RESEARCH LAB
The full text of this report is available for sale.When a ground and vegetation cover factor related to soil erosion is mapped with the aid of remotely sensed data, a cost-efficient sample design to collect ground data and obtain an accurate map is required. However, the supports used to collect ground data are often smaller than the desirable pixels used for mapping, which leads to complexity in developing procedures for sample design and mapping. For these purposes, a sampling ...


Cold Regions Data Acquisition and Analysis for Section 227 National Shoreline Erosion Control Development and Demonstration Program Miami Park South, Allegan County, Michigan SEP 2005 29 pages
Authors:  Michael G. Ferrick; Lawrence W. Gatto; Christopher R. Williams; ENGINEERING RESEARCH AND DEVELOPMENT CENTER HANOVER NH COLD REGIONS RESEARCH AND ENGINEERING LAB
The full text of this report is available for sale.Bank recession resulting from erosion and mass failure is a consequence of hydraulic forces and geotechnical processes. One important set of processes is soil freeze-thaw (FT) cycling and associated ground-ice growth and melt. In regions where seasonal frost forms soil FT processes usually cause more bank recession annually than other processes. The magnitude of FT effects is variable depending on soil type water content and freezing rate. The stability of ...

Authors:  OFFICE OF TECHNOLOGY ASSESSMENT WASHINGTON DC
The full text of this report is available for sale.Agricultural productivity has increased markedly in recent years-more rapidly, in fact, than productivity in the overall U.S. economy. Many attribute a large part of this growth to public sector agricultural research, which is carried out primarily by land grant universities and the U.S. Department of Agriculture's research agencies. Despite this success, however, new budget constraints, scientific advances, and public demands for environmental safety are presenting the agricultural research system with ...

Many stochastic models for these fertility trends have been proposed and shown to be efficient competitors to classical blocking designs. In this paper we shall restrict attention to trials where plot fertilities are correlated in only one direction. In the ...


Market Allocation of Agricultural Water Resources in the Salinas River Valley DEC 90 105 pages
Authors:  John P. Neagley; Robert T. O'Brien Jr; NAVAL POSTGRADUATE SCHOOL MONTEREY CA
The full text of this report is available for sale.The current drought conditions that the Central California coast has been facing and the increasing threat of saltwater intrusion have forced the Salinas Valley to consider alternatives that provide for conserving and allocating limited groundwater resources. Currently, groundwater resources are treated as a common pool resource where there are no clearly defined property rights for groundwater and there is no regulation of use. This thesis examines the question of how ...


Runoff Prediction Uncertainty for Ungauged Agricultural Watersheds DEC 90 19 pages
Authors:  David M. Goldman; Miguel A. Marino; Arlen D. Feldman; HYDROLOGIC ENGINEERING CENTER DAVIS CA
The full text of this report is available for sale.A physically based stochastic watershed model is used to estimate runoff prediction uncertainty for small agricultural watersheds in Hastings, Nebraska.

Authors:  Victor E. Diersing; Jeffrey A. Courson; Steven D. Warren; David J. Tazik; Robert B. Shaw; CONSTRUCTION ENGINEERING RESEARCH LAB (ARMY) CHAMPAIGN IL
The full text of this report is available for sale.Military training exercises are generally scheduled without consideration of annual variation in climatic conditions. Thus, many heavy, mechanized maneuvers are inadvertently conducted when soils are likely to be wet. This causes needless damage to soil and vegetation which reduces the amount of additional training use the land can receive. This report presents the results of an investigation of the utility of long-term precipitation and temperature data for military land-use planning. ...


An Analysis of the Surface Hydrology in the Galena Watershed: 1940-1987 12 APR 90

The full text of this report is not available and therefore is not for sale. This information is provided for reference purposes only.This study attempts to evaluate the influence of soil conservation practices on the surface hydrology in the Galena watershed. Poor soil conservation practices within the watershed from the mid-1800s until the mid- 1900s increased surface runoff while decreasing baseflow. The poor soil conservation practices affected soil erosion, flood magnitudes, channel morphology, and sedimentation processes. The influence of poor soil conservation practices within the Galena watershed reached a maximum during the ...
