A review of erosion and sediment transport models
Information on sediment and nutrient export from catchments and about related erosive processes is required by catchment managers and decision-makers. Many models exist for the consideration of these processes. However, these models differ greatly in terms of their complexity, their inputs and requirements, the processes they represent and the manner in which these processes are represented, th...
متن کاملWeek 3 ( Feb 12 ) : Erosion and Sediment Transport
Sweeney, K.E., Roering, J.J., Ellis, C., 2015. Experimental evidence for hillslope control of landscape scale. Science 349, 51–53. This study derived laboratory experiments to test the landscape evolution theory, which states that climate sets the scale of landscape dissection through the competition between diffusive and advective processes. Convex hillslopes are produced through diffusive pro...
متن کاملFeedbacks between erosion and sediment transport in experimental bedrock channels
Natural bedrock rivers flow in self-formed channels and form diverse erosional morphologies. The parameters that collectively define channel morphology (e.g. width, slope, bed roughness, bedrock exposure, sediment size distribution) all influence river incision rates and dynamically adjust in poorly understood ways to imposed fluid and sediment fluxes. To explore the mechanics of river incision...
متن کاملProglacial lake sediment records of Holocene climate change in the western Cordillera of Peru
Sediment records from proglacial lakes between 9 and 10 S in the western Cordillera of the Peruvian Andes document the waxing and waning of alpine glaciers since the end of the Lateglacial stage. These records from the southern tropical Andes provide supporting evidence that the early Holocene (between 12 and 8 ka) was relatively warm and dry, and the middle Holocene (between 8 and 4 ka) was ma...
متن کاملClastic sediment flux to tropical Andean lakes: records of glaciation and soil erosion
We developed records of clastic sediment flux to 13 alpine lakes in Peru, Ecuador, and Bolivia, and compared these with independently dated records of regional glaciation. Our objectives are to determine whether a strong relationship exists between the extent of ice cover in the region and the rate of clastic sediment delivery to alpine lakes, and thus whether clastic sediment records serve as ...
