Conceptual watershed model developed to examine water quality as it is affected by soil erosion from agriculture and urban areas (Young et al., 1987). AGNPS has three major components: hydrology, soil erosion and nutrient pollution. The hydrological function provides prediction of runoff volume and peak flow rate. The soil erosion function includes soil erosion and sedimentation. The nutrient f...

The microtopography of the soil surface (mm to dm range) is a crucial factor in understanding and monitoring soil erosion. It influences the dissipation of rain-drop energy, determines the hydraulics of surface runoff, and it is changed by transport and sedimentation of soil particles. We used a high-resolution terrestrial laser scanner to assess erosion risks due to mechanized logging with cra...

In many ways, sediment transport dynamics in mountain environments differ from those of the lowlands. The high relief and the steep slopes are an obvious feature of mountain areas. The cold climate is another factor controlling runoff and erosional processes, and the distribution of vegetation is also controlled by the prevailing climate. Above the tree line, processes of erosion are more inten...

The terrestrial Quaternary stratigraphic record of British Columbia is largely a product of brief depositional events separated by long periods of nondeposition and erosion. Thick, stratified Quaternary sediments are present mainly in valleys and coastal lowlands and accumulated during periods of growth and decay of the Cordilleran Ice Sheet. At glacial maxima, till was deposited over large are...

Among the various hazards created by nature on the earth’s surface, the one caused by flood and river bank erosion is more common and quite devastating. Like, earthquake and volcanic eruptions, it also affects human activities in various ways wherever it occurs. Erosion, transportation and deposition are the main functions of a river. Through these activities, it creates different landforms and...

One of the most frequently quoted ecosystem services of seagrass meadows is their value for coastal protection. Many studies emphasize the role of above-ground shoots in attenuating waves, enhancing sedimentation and preventing erosion. This raises the question if short-leaved, low density (grazed) seagrass meadows with most of their biomass in belowground tissues can also stabilize sediments. ...

The Late Cretaceous to Early Tertiary subsidence history of the Northern Calcareous Alps (NCA) records the effect of two independent basin formation mechanisms at the northern leading margin of the Austroalpine unit. The terrestrial to shallow-marine sediments of the Lower Gosau Subgroup were deposited mainly within small, fault-bound basins during a phase of strike-slip faulting from the late ...
