Evaluation of some software measuring displacements using GPS in real-time
John O. Langbein
2006, Open-File Report 2006-1235
For the past decade, the USGS has been monitoring deformation at various locations in the western United States using continuous GPS. The main focus of these measurements are estimates of displacement averaged over one day. Essentially, these consist of recording at 30 seconds intervals the carrier-frequency phase-data (equivalent to travel-time)...

Impacts of landslide dams on mountain morphology
Robert L. Schuster
2006, Book chapter, Landslides from massive rock slope failure
Landslide dams can influence mountain-valley morphology significantly in the vicinity of the dam sites, as well as upstream and downstream. The effects are: (1) impoundment of lakes that result in changes in stream gradients, (2) deposition of lacustrine and deltaic sediments in these impoundments that causes changes in surficial morphology...
Use of models to map potential capture of surface water
Stanley A. Leake
2006, Conference Paper
The effects of ground-water withdrawals on surface-water resources and riparian vegetation have become important considerations in water-availability studies. Ground water withdrawn by a well initially comes from storage around the well, but with time can eventually increase inflow to the aquifer and (or) decrease natural outflow from the aquifer. This...
