Sand covers only about 20 percent of the Earth's deserts. Nearly 50 percent of desert surfaces are gravel plains where removal of fine-grained material by the wind has exposed loose gravel and occasional cobbles. This web page, produced by the U.S. Geological Survey, features text and photographs that describe desert landforms, soils, plants, and the role of water in the formation of desert landscapes.

No solution lasts long in an entrepreneurial milieu whose underpinning is "creative destruction". Y

Advances in nanotechnology
In this podcast, Professor Moriarty discusses nanotechnology, and how it has led to a convergence of the traditional sciences. He talks about the commercial applications of nanotechnology such as hard disk technology in laptops, stain free materials and fabrics, self-cleaning windows and advanced water filtration. He also touches on some of the myths about nanotechnology as well as some of the real dangers of Nanotechnology and the steps governments are taking to regulate it. Professor Moriarty
Water Science Curriculum
Water Science offers a two-semester water resource management curriculum for second year technical students or undergraduates in water resource management, water science, or environmental resource management programs. Water Science is divided into 6 major units. Each unit is divided into modules encompassing approximately a week's worth of lectures and labs.
Art and Life in Africa Project
This site presents a program that places art in the context of people's lives so our students will understand how important and effective a tool art is in solving problems and overcoming adversity.
