These maps portray landslides, geomorphic features related to landsliding, relative landslide potential, geology, and stream channel geomorphic conditions in the Elk River watershed, Humboldt County, California.
Digital geospatial data sets for two maps (Plate 1, Elk River watershed, Humboldt County, California, geologic and geomorphic features related to landsliding; and plate 2, Elk River watershed, Humboldt County, California, relative landslide potential with geologic and geomorphic features).
This collection of vector and raster data layers contain the results of landslide mapping of the Albion River Watershed, Mendocino County, California; includes geologic and geomorphic features related to landsliding and relative landslide potential.
The analysis was conducted under a Geographic Information System GISS) environment, and the landslide potential was defined by the information value proposed by Jade and Sarkar [Eng. Geol. 36 (1993) 91].
Using LiDAR from the Oregon Coast Range, we found gentler channel gradients, wider valleys, lower gradient hillslopes, and less shallow landslide potential in an above-barrier catchment compared to a neighboring catchment devoid of persistent knickpoints.
These documents, Geologic and geomorphic features related to landsliding, Freshwater Creek, Humboldt County, California; and, Relative landslide potential map, Freshwater Creek, Humboldt County, California, were completed by James N. Falls in 1999 and issued as Open-file report 99-10 and 99-10a by the California Division of Mines and Geology.
There are various application of an accurate hazard map like deciding insurance rates, business and land-use planning, estimations of stability and landslide potentials of hillsides, allocation planning of funds for education and preparedness for concerned general public and society.
Where N 1, N 2, N 3 and N 4 are No of cell units representing the presence of landslides and potential landslide predictive factor, presence of landslides and absent of potential landslide predictive factor, absence of landsides and presence of potential landslide predictive factor and absence of both landslides and potential landslide predictive factor respectively.
Gomeza and Kavzoglub (2005) presented an approach for assessing the landslide risk potential, mainly for shallow landslides (Gomeza and Kavzoglub 2005).
Geological and geomorphological methods to identify landslide hazard potential are especially important in a region experiencing rapid urban development, widespread land use change and the construction of water resources projects on major rivers.
Further, for very deep earthquakes, the fault length is not really a significant factor in this context – only the magnitude would have an impact on the landslide triggering potential (through the use of AI).
