Extended abstract 1- Introduction      Soil erosion, as one of the most important environmental problems in the world, has a devastating effect on all life, natural resources and it's under human management. Considering that one of the important goals in the management of drainage of basins such as Gabric basin is preventing soil erosion, and also one of the important factors when designing d...

1 Abstract We present results of self-consistent experiments of basin formation by extension and basin inversion through subsequent contraction. Our viscous-plastic finite element models include feedback interactions between crustal deformation, the development of local shear zones, and sedimentation and erosion. The extensional basins show a high degree of sensitivity to crustal strain softeni...

Cohen, A. S., 1989. Facies relationships and sedimentation in large rift lakes and implications for hydrocarbon exploration: examples from lakes Turkana and Tanganyika. Palaeogeogr., Palaeoclimatol., Palaeoecol., 70: 65-80. Two African lakes, Turkana and Tanganyika, illustrate a spectrum of sediments and facies architectures which can occur in large rift lacustrine basins. They demonstrate cont...

The rivers from the Himalaya supply large quantities of particulate and dissolved materials to the oceans. Among the various rivers, the Brahmaputra ranks highest in contributing to the sediment budget of the Bay of Bengal. The erosion rates among the sub-basins of the Brahmaputra vary over 1–2 orders of magnitude, the highest being in the Eastern Syntaxis basin which is eroding at an enormousl...

Converting rangelands to arable land such as dry farming is widely practiced in many places in Iran. This activity could possibly contribute to the increase in downstream sedimentation. The effects of this activity on downstream watersheds are not well documented for many strategic areas in the country. One such area which is proposed for this study is the Kardeh drainage basin, located in the ...
