- Subsidence risk due to groundwater extraction in urban areas using fractal analysis of satellite images Ramiro Rodríguez Jorge Lira I. Rodríguez Ciencias de la Tierra faults subsidence groundwater Contamination fractal analysis Agriculture in urbanized areas of semi arid regions without surface water bodies depends on an intense use of groundwater. In Irapuato City, Mexico, there is a great concentration of agriculture and urban supply wells. The intense regional pumping regime is inducing subsidence. Eighteen subsidence fault systems were found with a total length of 27 km. More than 200 houses present damages. The presence of toluene in groundwater suggests that faults facilitate the migration of contaminants. A morphological analysis of agriculture land distribution in the urban area was carried out using satellite images. This morphological analysisshows the relevance of agriculture terrain distribution within the urban area. The morphologicalanalysis is applied on previously segmented crop fields as derived from the satellite image. Thisanalysis allowed calculation of agricultural land distribution and confirm the presences of wells. 2012 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56823351005 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.2 Vol.51
