USGS science for the Nation's changing coasts; Shoreline change assessment [ More info] Shorelines are always changing, yet we use these areas heavily. This shows what we measure and how, to help adapt to changing coastal zones.
Using science to strengthen our Nation's resilience to tomorrow's challenges: understanding and preparing for coastal impacts [ More info] Specific steps that USGS is taking to gather scientific information that will help coastal communities prepare for changes, both sudden, like hurricanes, and gradual, like rising sea level.
Using terrestrial light detection and ranging (lidar) technology for land-surface analysis in the Southwest [ More info] Tripod-mounted lidar makes it inexpensive and efficient to measure and map geographic features that change with time, such as sand dunes and erosional features, and soil microtopography.
