LAB 11: DRYLAND LANDFORMS, HAZARDS, & RISKS

DRYLAND PROCESSES & FEATURES

Wind Erosion processes and effects are briefly noted in this Geoindicators summary report.

Dune Formation and Reactivation are briefly discussed in this Geoindicators summary report.

Dust Storm Magnitude, Duration, & Frequency are briefly discussed in this Geoindicators summary report.

Dunes & Aeolian Processes at White Sands National Monument are described at this site.

Desert Surface Crusts & Fissures are briefly discussed in this Geoindicators summary reprot.

Cross-bedding in eolian sand dunes is studied, modeled, and pictured at this U.S. Geological Survey bedform sedimentology site.

DRYLAND HAZARDS & RISKS

Drought News has up-to-date international news reports on regions affected by drought and their current status.

Land Degradation & Desertification is a CIESIN Thematic Guide that introduces these topics and defines the terms relative to their international application.

Desertification & Climate Change describes the global extent of desertification, notes how regional climate variability can accelerate desertification, and also notes how desertification contributes to global climate change.

USGS Desertification page provides links to useful information on desertification, including a United Nations report on desertification and a plan to combat desertification.

The NASA Natural Disasters Reference Database has background information on drought.

Review of the 1995 Desertification Convention is a long report by Kyle Danish on the international effort of 103 nations to address the global desertification hazard.

United Nations Convention to Combat Desertification has many hotlinks to sites on desertification.

GIS Techniques Using NOAA Data improve efforts to monitor desertification. This site uses excellent imagery to show examples of this monitoring method.

LINKS ON SPECIFIC LOCATIONS DISCUSSED IN THIS LABORATORY

Desertification Potential of Nebraska's Sand Hills is briefly described here. The site includes an aerial photograph of the Sand Hills geomorphology.

Age and paleoenvironments of Nebraska's Sand Hills are determined on the basis of studies of fossil grassland pollen and are discussed in abstracts at this site
