Natural hazards on alluvial fans: the debris flow and flash flood disaster of December 1999, Vargas state, Venezuela Natural hazards on alluvial fans: the debris flow and flash flood disaster of December 1999, Vargas state, Venezuela
Large populations live on or near alluvial fans in locations such as Los Angeles, California, Salt Lake City, Utah, Denver, Colorado, and lesser known areas such as Sarno, Italy, and Vargas, Venezuela. Debris flows and flash floods occur episodically in these alluvial fan environments, and place many communities at high risk during intense and prolonged rainfall. In December 1999...

Utilizing Mars Digital Image Model (MDIM) and Mars Orbiter laser Altimeter (MOLA) data for photogrammetric control Utilizing Mars Digital Image Model (MDIM) and Mars Orbiter laser Altimeter (MOLA) data for photogrammetric control
The USGS is producing digital elevation models (DEM) and topographic maps of Mars at scales of 1:250,000 to 1:1,000,000. The initial source material will be Viking Orbiter images, with a later transition to Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) when stereo coverage from that source is available for topographic mapping. The digital terrain models and topographic maps...
