NON-REVENUE WATER (NRW) AND 3D HIERARCHICAL MODEL FOR LANDSLIDE

H. HARIRI ASLI, A. HOZOURI

Abstract


The landslide is triggered by a specific event such as a heavy rainfall, an earthquake, a slope cut to build a road, and many others. The landslide can cause Non-revenue water (NRW) in water reservoirs, water transmission pipelines and water distribution network.  In present work, based on the analytical methods for landslide phenomenon, the water facility accidents and water loss were investigated for the highland city named Masal in the north of Iran. The Geospatial Information System (GIS) as a conceptualized framework provides the ability to capture and analyses spatial and geographic data in present work. The ArcGIS software analyzed the geospatial data. The Analytic Hierarchy Process (AHP) as an analysis algorithm was applied for finding the percentage of landslides based on the GIS. As a final result, the slopes of 10 to 30 degrees accounted for the highest percentage of landslides. These slopes were assumed as hazard and important cases for the water facilities disaster

Keywords
