Geomorphic and hydrogeologic studies have shown that the material, topographic, ground‐water, and surface‐water characteristics of a particular landscape position are all related. Because topography is related to the local material and surface‐water characteristics and because the ground‐water regimen is related to the local materials and topography, an analysis of the topography should allow the prediction of the material, ground‐water, and surface‐water characteristics of a disposal site within the local area. Topographic consideration of potential solid waste disposal sites thus provides insight about the physical characteristics of the site and shape of the resulting contamination enclave. Seven possible topographic positions for disposal sites are floodplain, valley terrace, valley side, upland crest, upland ravine, upland valley and upland flat interfluve. Upland sites are characterized by the outward flow of both ground water and surface water, whereas valley sites are characterized by the through flow of both ground and surface water. At the present time, upland sites are considered preferable over valley sites because of the greater likelihood of the refuse remaining dry. An analysis of ground‐water flow patterns indicates that the greatest potential for extensive ground‐water contamination exists for upland sites, which are in ground‐water recharge areas; and the least potential for extensive ground‐water contamination exists for properly placed valley sites, which are in ground‐water discharge areas.
