Integrating satellite and climate data for U.S. drought mapping and monitoring: First steps Integrating satellite and climate data for U.S. drought mapping and monitoring: First steps
Although droughts are normal, recurring climate phenomena, they challenge our current ability to plan, predict, monitor, and provide relief to drought stricken areas. Because of the spatial and temporal variability of droughts, we need to improve the tools available to map and monitor them on many scales from local to national. A team of researchers from the US Geological Survey’s EROS...

A prototype drought monitoring system integrating climate and satellite data A prototype drought monitoring system integrating climate and satellite data
Droughts are natural hazards with varying patterns in space, time, and intensity. Their dynamic character challenges our ability in planning, predicting, monitoring, and providing relief to affected areas. Because of the spatial and temporal variability and multiple impacts of droughts, we need to improve the tools and data available for mapping and monitoring this phenomenon on all...

Is it More Important to Characterize Heterogeneity or Differences in Hydraulic Conductivity Measurements? Is it More Important to Characterize Heterogeneity or Differences in Hydraulic Conductivity Measurements?
As a first step toward understanding the role of sedimentary structures in flow and transport through porous media, this work deterministically examines how transport simulations compare to observed transport through simple, artificial structures in a laboratory experiment. Small-scale laboratory-measured values of hydraulic conductivity were used to simulate transport in an intermediate...

Depositional sequences and facies in the Torok Formation, National Petroleum Reserve, Alaska (NPRA) Depositional sequences and facies in the Torok Formation, National Petroleum Reserve, Alaska (NPRA)
Brookian turbidites (Cretaceous through Tertiary) have become oil exploration objectives on the NorthSlope of Alaska during the past decade, and it is likely this focus will extend into the National Petroleum Reserve-Alaska (NPRA). A regional grid of 2-D seismic data, sparse well control, and field work in the Brooks Range foothills provide constraints for an ongoing effort to establish...

Effects of water use diversion regulation and conservation on sediemtn transport with comparisons from the United States Effects of water use diversion regulation and conservation on sediemtn transport with comparisons from the United States
Too much sediment and too little water are related problems in China’s Yellow River Basin. Sediment yield in the basin averages about 2,100 t/(km2·a), greatest is of the world’s large rivers although the Yellow River ranks 31st in mean flow. A quarter of the sediment deposited in the 780-km lower reach, causing bed levels to rise an average of a meter per decade wang and other. Sediment

11 things a geologist thinks an engineer should know about carbonate beaches 11 things a geologist thinks an engineer should know about carbonate beaches
This is a review of the geological aspects of carbonate beaches that a geologist thinks may be useful for an engineer. Classical geologic problems of carbonate beaches, for example how ancient examples are recognized in rock sequences, are of little interest to engineers. Geologists not involved in engineering problems may find it difficult to know what an engineer should understand...

USGS high resolution topo-mapping of Mars with Mars Orbiter Camera Narrow-Angle images USGS high resolution topo-mapping of Mars with Mars Orbiter Camera Narrow-Angle images
We describe our initial experiences producing controlled digital elevation models (DEMs) of Mars with horizontal resolutions of ≤10 m and vertical precisions of ≤2 m. Such models are of intense interest at all phases of Mars exploration and scientific investigation, from the selection of safe landing sites to the quantitative analysis of the morphologic record of surface processes...
