Abstract:Landfill site selection is a critical issue in the urban planningprocess because of its enormous impact on the economy, ecology, and theenvironmental health of the region.
Landfill site selection process aims tolocate the areas that will minimize hazards to the environment and publichealth. The purpose of this study was to evaluate the location of the currentlandfill and to determine suitable landfill site selection by using thegeographical information system. The final index model was grouped into threecategories as “low suitable”, “moderate” and “best suitable” using the weightedoverlay tool. Chapter 1 1.1 Background:One of the most important causesof environmental pollution is certainly an inadequate waste management.
Thethree factors that have primarily influenced this problem area are: everincreasing amount of municipal solid waste, increasing amount and types ofhazardous waste, as well as lack of awareness on the importance of actingpromptly in this field. Particular problemsin waste management occur in developing countries, where the awareness of theimportance of environmental protection has not yet achieved a satisfactorylevel and where, out of economic or political reasons, professional guidelinesassociated with waste management are not observed. Problems emerge either dueto a lack of legislation, or obsolete legislation, lack of trained personnel,inadequate waste management infrastructure, financial constraints in theestablishment of a modern waste management system, population lacking theawareness about solid waste management, impossibility of selecting appropriatespace for landfill development, lack of standards, etc. Waste management is a complex process which implies acontrol of the entire waste management system (from waste generation, throughcollection and transportation of waste, to waste treatment and disposal), alongwith the support of legislation and appropriate institutional organization.As a result of the increase in population, industrial and agriculturaldevelopment, improved living standards and the change in household andhousehold consumption, hospitality and failure to follow the proper rules insolid waste management Khartoum is producing huge amounts of solid waste daily;1.
2 Importance of landfill siteselection: In planning, landfillsite selection occupies extremely important place. In the widest sense, thenatural, social, political, economic and technical factors have an importantrole in landfill site selection, thus it follows that the selection is to bemade by a multidisciplinary team of experts. Given that landfill constructionis considered as a noneconomic activity, a special task is to select landfillsite from the aspect of the use of buildable land and its price, as well as othernatural or urban values which have an important role in relation to rationalityand planned landfill remediation or its rehabilitation, i.e.
reconstruction5. 1.3 Problem statement:According to the Supreme Council for the Environment of thestate, Khartoum produces between 3,500 to 4,500 tons per day (about 150,000tons monthly). The solid waste is transferred to a Intermediate station and then it gottransferred in a huge waste trucks to the master landfill which is located inthe south of Khartoum about 4 km to the northeastof a village called “Taybat el-hasanab”.
When many chemicalscombine, they create a toxic liquid. When animals and plants come into contactwith this toxic mixture, they are very seriously harmed. The master landfill ofKhartoum city is surrounded by agricultural areas, animals and residentialareas, and this is a harmful neighborhoodwhich is threatening their lives with danger.1.4 Study area:KHARTOUM IS THEcapital city and administrative region of the Republic of the SUDAN, located atthe confluence of the Blue and White NILE rivers. Khartoum is thesecond-largest city in North Africa, with an estimated population of 2.5million in the city proper, and up to 7 million in the Greater Khartoumdistrict, which includes Khartoum General, Khartoum North, and Omdurman, eachcity linked by bridges.Khartoum is locatedat latitude 15°33?53.

1 KhartoumPopulation:Khartoum, together withthe two cities, Omdurman and Khartoum North (Bahri), these cities jointlycalled the tri-capital, constitute the National Capital of the republic of Sudan,their population has grown to over 5 million people. But the population ofKhartoum city only is 1,974,647 .Figure 2. Map representing the density of Sudan states. 1.
5 Objectives:1. To know the sites of the existing waste dumps in the Khartoum area from an environmental and geographical perspective.2. To evaluate the current sites of the waste dumps and how much they conform to the standards, specifications and conditions of health and environment.3. Knowing about the standards and conditions used to plan the best landfill sites.
4. To produce a local digital map of Khartoum showing the best locations of waste dumps using GIS.5. To provide a range of suggestions and recommendations that may benefit planners and decision makers.
