Lake Bourget regional erosion patterns reconstruction reveals Holocene NW European Alps soil evolution and paleohydrology
Two well-dated ca Holocene-long sedimentary sequences from deepest parts of Lake Bourget provide new insights onto the evolution of erosion patterns at a regional scale in NW European Alps. The combination of high resolution geochemistry – XRF core scanning, calibrated by 150 punctual measurements – and isotope geochemistry (ɛNd) of the terrigenous fraction permitted the reconstruction not only...

متن کاملEvaluation of Soil Erosion and Soil Erodibility Factors for Composted Organics on Highway Right-of-Ways
Runoff and interrill erosion were measured on three composted organics applied at 5-cm and 10-cm depths, a topsoil treatment (15-cm application), and the existing soil on a highway embankment with a 3 to 1 slope. Treatments were tested immediately after preparation and six weeks later to allow for the vegetative cover crop to grow. Rainfall simulations were conducted at an average intensity of ...
متن کاملMeasure Soil Erodibility in Situ
The assessment of the erodibility of soil materials is essential for analyzing and modeling rill, gully, streambed, streambank, spillway, and embankment erosion. A submerged jet−testing apparatus has been developed and used for characterizing soil erodibility in several applications as cited in the literature. The apparatus has been developed based on knowledge of the hydraulic characteristics ...
متن کاملTopographic controls on erosion rates in tectonically active mountain ranges
The functional relationship between erosion rate and topography is central to understanding both controls on global sediment flux and the potential for feedback between tectonics, climate, and erosion in shaping topography. Analysis of a high-resolution (10-m-grid) DEM transect across the convergent orogen of the Olympic Mountains reveals a non-linear relation between long-term erosion rates an...
