Himalayan mountains are one of the most seismo-tectonically active zones on surface earth. Recurring moderate and high magnitude earthquakes not uncommon in this region. This paper maps earthquake vulnerability region using integrated multi-criteria decision models. Factors which may influence a can be categorized social, geotechnical, structural, physical parameters. We have used analytical hi...

Abstract The South-to-North Water Diversion Project (SNWDP) is a cross-basin large-scale water infrastructure, whose operational management faces many complex risks. This study constructs an safety risk analysis model based on fuzzy VIKOR-FMEA. First, the expert team used linguistic variables to evaluate severity of each failure mode (S), frequency occurrence (O), and difficulty detection (D) i...

Abstract Exploration and prioritization of potentially mineralized areas by integrating different geoscientific datasets help to manage the time costs an exploration project. In this study, copper explored were done on Kerman belt, which was formed due subduction Arabian plate under Iranian plate. After processing layers (geology, hydrothermal alteration zones, stream sediment geochemistry, air...
