Conversion trends of rangelands to dry farming and its effects on erosion and sediment yield in Kardeh drainage basin

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 ...

Evaluation of soil erosion and sediment yield estimation various empirical model by observation values (Case study: Babolroud watershed, Mazandaran Provienc)

In this study where done in Babolroud basin, seven models include MPSIAC, EPM, Fournier, Douglas, Kirkby, Geomorphology and Hydrophysical was evaluated to determine the best model  for estimation of soil erosion and sediment yield. These models have not been compared together as integrated in the previous researches. The zoning soil erosion intensity map was prepared for each model using GIS. T...

Estimating sediment yield from a paved forest road (Asphalt) (Case study: Watershed Leyle, Ravansar)

Extended abstract 1- Introduction Forest roads are among the largest sediment transport sources to drainage network. So, estimating the sediments of the road network is an important factor in the evaluation of the impact of the road construction. One of the biggest problems caused by the road construction in the forest is the increase in various forms of erosion, such as Gully erosion and mas...

a study on insurer solvency by panel data model: the case of iranian insurance market

the aim of this thesis is an approach for assessing insurer’s solvency for iranian insurance companies. we use of economic data with both time series and cross-sectional variation, thus by using the panel data model will survey the insurer solvency.
