The morphology of passive continental shelves is dictated by the input of sediments from rivers and their redistribution by waves, currents, and gravity-driven flows. The pathways followed by sediments sculpt a landscape whose diversity is rarely matched on Earth’s surface. Sediments are released to the shelf from triangularly shaped, elongated, and dendritic deltas. Barrier islands rise from g...

This paper presents an automated classification system of landform elements based on object-oriented image analysis. First, several data layers are produced from Digital Terrain Models (DTM): elevation, profile curvature, plan curvature and slope gradient. Second, relatively homogenous objects are delineated at several levels through image segmentation. These object primatives are classified as...

Landslides are important components of global geoheritage, but awareness their significance and value in such terms seems scanty the scientific community. normally identified among various features geological geomorphological interest, often considered a source hazard. However, they seldom as geosites part geoheritage. This paper aims at filling these gaps by highlighting importance landslides ...

We investigated the role of abiotic factors in controlling patterns of longterm windthrow in the pristine coastal temperate rain forests of southeast Alaska. Our objectives were to test the extent to which long-term patterns of windthrow can be predicted spatially at the landscape scale by using four abiotic factors (slope, elevation, soil stability, and exposure to prevailing storm winds), eva...
