Geomatics tools and AHP method use for a suitable communal landfill site: Case study of Khenifra region - Morocco

The management of household waste is a major environmental problem in all moroccan communities. this is linked to several factors including the significant quantity of waste produced and inadequate infrastructure. these factors create a significant pressure on the environment and led to negative impacts on natural resources and the health and hygiene of the population. the khenifra region is characterized by diverse and fragile natural environment resources. therefore,it is necessary to preserve and protect this heritage against pollution. this paper describes an approach for sites selection to store solid waste by combination of spatial analysis and multi-criteria decision analysis methods. based in an integration and treatment of exclusion criteria in a geographic information system (gis),we determinate the free surfaces screened,afterward we evaluate them on the basis of the assessment criteria using the ahp (analytical hierarchy process) method. in order to appreciate the socio-economic and hydrological aspect which are favored from geological and land use factors,field controls have been carried out to determine the accuracy and relevance of the suitable places. finally,we chose 3 adequate sites which are considered the most favorable places for controlled discharge installation in khenifra region. © 2017 university of mohammed premier oujda morocco.
