The bedrock and surficial geologic map of the Satan Butte and Greasewood 7.5' quadrangles was completed in a cooperative effort of the U.S. Geological Survey (USGS) and the Navajo Nation to provide regional geologic information for management and planning ...

Christchurch City Council requested GNS Science to carry out geomorphic mapping of the near-surface materials and processes present in the Port Hills of Christchurch. The purpose of this work is to provide information relating to near-surface geological materials ...

Electrical resistivity imaging and geological mapping were used to study the geology and delineate geologic structures at the Northeastern part of Ago Iwoye, Southwestern Nigeria. Two areas which include Mini-Campus Olabisi Onabanjo University (MCOOU) and ...

The protective effect of forests against rockfall cannot be neglected in risk management. This is, of course, under the condition that a considerable slope length in the transit area is forested and that a tree diameter distribution which can provide sufficient ...

Firstly, the report will discuss landslide susceptibility mapping methodologies including geomorphological mapping, physically-based models, heuristic and statistical approaches, review methodological comparison studies, terrain division approaches, temporal ...

Rock fall hazard assessment and hazard mapping are essential for the risk management of vulnerable areas. This paper analyses some issues concerning fragmental rock fall hazard mapping methodologies.

Landslides are a recurring problem on hillslopes throughout the Puget Lowland, Washington, but can be difficult to identify in the densely forested terrain. However, digital terrain models of the bare-earth surface derived from LIght Detection And Ranging ...

The accuracy of forest stand type maps derived from a Landsat Thematic Mapper (Landsat TM) image of a heterogeneous forest covering rugged terrain is generally low. Therefore, the first objective of this study was to assess whether topographic correction of ...

The need for hydrological research, basic as well as applied, is substantial to help rationally manage the world’s water resources. To satisfy this need, and the interest of Member States, UNESCO, in 1975, launched a long-term intergovernmental programme, ...

The present study is linked to the Ancient Pacific Margin NATMAP program and is part of a multi- disciplinary effort by the B.C. Geological Survey Branch within the region. Ray et al. (2001) and Dunne et al. (2001) are conducting a detailed examination of ...
