The rock mass erosion of dam spillways, a phenomenon involving the interaction between hydraulic load water and capability to resist its destruction, remains critical safety issue. resistance can be estimated through several erodibility indices, including those Kirsten, Pells or Bollaert. Several indices have been developed link parameters water, i.e., applied on mass. use average flow velocity...

the mahabad river watershed has been exposed to severe erosion as a result of landuse change. the aim of this study is to quantify the amount of sediment yield and the relationship between land use change and slope. different sources such as geologic and topographic maps, satellite images, hydrometric as well as meteorological data were used to extract and gather the information needed for this...

This work aims to verify the effects of natural structure a residual soil on its erodibility and potential, employing compaction, restore erosion resistance. It is gneiss that occurs in state Santa Catarina, Southern Brazil. Infrastructure earthworks expose this material action water, which can develop severe erosive features. The evaluation was made using MCT methodology based infiltrability m...

Post-wildfires geological hazards are an emerging problem in many places, including areas not typically associated with these events such as the Alpine Region. Hazards connected post-fire processes debris-flows and flood-type threatens people, infrastructures, services economical activities. Apart from a few examples, there is lack of models available to quantify increase susceptibility result ...

Bayan District has a wavy to mountainous topography. The type of soil in the area is classified as Inceptisol, so it very susceptible erosion. An agroforestry system, with various stands perennial crops, been developed area, conservative measure support sustainability land resources. This study aims assess value erodibility Elephant foot yam-based systems five types stands, namely: Teak (A1), C...
