Purposefulness of determining the construction sites of lattice-stone structures using network analysis process (Case study: Khorramabad County)

Nowadays, due to the large amount of funds allocated to the reform clauses in the construction of watershed management projects, the review of priorities in locating critical points before the implementation of structures should be done comprehensively and accurately. Accurate knowledge of erodible points and effective factors in it is a necessary measure, which can be minimized by timely watershed management measures, whether structures or other structures or a combination of them, the severity of damage caused by erosion and sedimentation of basins. Therefore, careful selection of priorities and policies in the activities of watershed structures has a significant impact. In this study, which was carried out with the aim of basic management and planning, lattice-stone structures in Khorramabad city in order to control erosion and sediment from four criteria: hydrological, topographic, economic and social and other indicators related to erosion and fault, which are 14 sub-indicators. By using the network analysis process to weight these parameters and enter it into the GIS. 0.14, 0.141 and 0.126, which can be used to prevent the risks of erosion and sediment, which is visible in 4.5% of the study area.

In general, according to the general objectives of this study, which is to identify the points of formation of lattice-stone structures and its roles in reducing damage caused by floods, erosion and sedimentation in villages, roads, farms, gardens, etc. Prevention of life and financial injuries According to the present study, a scientific, appropriate and simple solution has been presented.Keywords: check dam, location, Khorramabad, network analysis process.
