in iran due to the lack of long experience in the implementation of soil conservation and watershed management plans, these measures have not been evaluated quantitatively and specific methods for this purpose have not been provided. in this research effort is to investigate the effect of watershed management operations performed in can basin in 1379, on the amount of erosion and sedimentation ...

Extensive exposures of a light-toned deposit (LTD) occurs on the northeastern interior slope Hellas basin. This is floors all but youngest craters greater than 30 km in diameter study region centered at 83°E and 30°S, as well crater exterior walls, intercrater plains, northern bordering slopes Navua Valles. Stratigraphic relationships indicate that LTD was emplaced terrain-conforming mantle sev...

The use of gravels as syntectonic indicators of thrusting has recently been questioned by foreland-basin models that assign gravels to a post-thrusting interval of progradation, except in very proximal areas. On the basis of precise temporal control provided by magnetostratigraphically dated sections, the history of gravel progradation after a major thrusting and uplift event in the northwester...

the result of wind dynamic (capacity and potential) is transport of soil or sediment particles and subsequent formative desert landforms based on the severity of erosion or sedimentation. the khartouran region, because of its geology, geomorphology and climatology conditions is a special place in the arid region on the closed basin of dasht-e-kavir. it is evident that the ecosystem balance of t...

Modeling of sediment transport in relation to changing land-surface conditions against a background of considerable natural variability is a challenging area in hydrology. Bayesian dynamic linear models (DLMs) however, o€er opportunities to account for non-stationarity in relationships between hydrologic input and basin response variables. Hydrologic data are from a 40 years long record (1951±1...
