Analysis of Analytical Hierarchy Process Method to Prioritize and Determine the Most Important Factors Influencing Sediment Yield in Semi-arid Region of Iran
Journal Title: International Journal of Farming and Allied Sciences - Year 2015, Vol 4, Issue 1
Abstract
In order to evaluate the Analytic Hierarchy Process (AHP) method to prioritization and determines the most important factor on sediment yield the results were compared with Linear regression analysis (LRA). For this purpose selected 18 experimental erosion plots with an area of 40 m2 in control and sample sub-catchments of Kakhk experimental catchment located in the Gonabad region of the Khorasan Razave Province in the northeast of Iran. than was selected topographical, hydrological, soil texture, land cover and rainfall factors and determine the most important factor on sediment yield have been used of both AHP and LRA. In AHP weighting the selected factors and ranking them based on their weights. By LRA was assessed the relationship between sediment yield and each of selected factors. Then were prioritized and ranked them based on their correlation coefficient. The results showed that only both AHP and LRA reports runoff depth as the most important factor on sediment yield. But because of the non-linear relations and complex interactions between the criteria that influnce on sediment, AHP method only able to identify the most important factor and Ranking criteria based on may be different with fact on land. Therefore in sediment yield AHP method can only provide a general overview of the subject.
