Measure 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 کاملEvaluation soil erodibility in catchment of Torogh dam of Mashhad
Extended abstract 1- Introduction Soil erosion is one of the most important problems in the arid and semi-arid areas in Iran and the knowledge about its content has an important role on the management practices of soil conservation. Topography as one of the soil-making factors affects the physical properties of the soil through the aspect and the degree of the slope. The aspect of the slope c...
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 کاملDetermining the Relation between Soil Erodibility and Spatial Variability of Erosion Properties Using Geostatistical Techniques at the Alqueva Reservoir Area
Soil erosion risk assessment at the watershed of Alqueva is urgently needed to conserve water resources and prevent the accelerated dam siltation. The variation of soil properties is one of the most important reasons for the spatial variability of vegetation cover and erosion. In order to achieve more and better management of rangelands around the largest reservoir of Europe, it is essential to...
متن کاملSpatial variability of soil properties and soil erodibility in the Alqueva reservoir watershed
The aim of this work is to investigate how the spatial variability of soil properties and soil erodibility (K factor) were affected by the changes in land use allowed by irrigation with water from a reservoir in a semiarid area. To this end, three areas representative of different land uses (agroforestry grassland, lucerne crop and olive orchard) were studied within a 900 ha farm. The interrela...
