Erosion patterns in a sediment layer.

چکیده
We report here on a laboratory-scale experiment which reproduces a rich variety of natural patterns with few control parameters. In particular, we focus on intriguing rhomboid structures often found on sandy shores and flats. We show that the standard views based on water surface waves do not explain the phenomenon, and we evidence a different mechanism based on mud avalanche instability.

Soil Erosion Model Implication (Case Stady: Minab Basin)
Soil erosion is an inevitable phenomenon that additive erosion caused Soil degradation. Additive Soil erosion is one of the major obstacles to achieve the development of agriculture and natural resources. Thus, knowledge of the status and trends of soil erosion and sediment production in the watersheds is one of the most important tools for planning and decision-making. Models are the most popu...
متن کاملUnderstanding rill erosion rate in dry-wet condition
Rill erosion is considered to be the most important process affecting soils created by the concentrated flow of water. In this research to quantify sediment transport and runoff in natural rills, two rill experiments under dry and wet conditions were accomplished in November 2013 in the Golestan Dam. Filed experiments lead to a closer understanding of the dynamics and power of different soil er...
متن کاملEstimating river suspended sediment yield using MLP neural network in arid and semi-arid basins Case study: Bar River, Neyshaboor, Iran
Abstract Erosion and sedimentation are the most complicated problems in hydrodynamic which are very important in water-related projects of arid and semi-arid basins. For this reason, the presence of suitable methods for good estimation of suspended sediment load of rivers is very valuable. Solving hydrodynamic equations related to these phenomenons and access to a mathematical-conceptual mode...
متن کاملLong term coastal erosion and shoreline positions of Sri Lanka
Coastal zone of Sri Lanka is a key to sustainable development of the country. The erosion of country’s coastal zone has been identified as a long standing problem. Therefore, coastal sediment dynamics around the country has to be identified to develop an appropriate coastal zone management plan. Remote sensing and GIS techniques can be used for quantitative and qualitative analyses of coastal p...
متن کاملPartitioning total erosion on unpaved roads into splash and hydraulic components: The roles of interstorm surface preparation and dynamic erodibility
Field rainfall simulation experiments at two sites are used to partition sediment transport on unpaved roads into splash and hydraulic erosion components. Rain splash processes contributed 38–45% of total sediment output, with instantaneous contributions being variable throughout 60-min high-energy events. For lowand medium-magnitude rainstorms, splash erosion on roads is initially controlled b...
