In arid urban environments, wastewater flow associated with oxidation ponds has a negative effect on the environment via geological disaster, slope stability and gully erosion. In our study, remote sensing (RS) and geoelectrical data are integrated to understand the wastewater flow paths around waste stabilization ponds built in desert lands. Firstly, the water-logging appearance is distinguished by monitoring land use/land cover changes using four temporal satellite images. Moreover, the wastewater flow paths and land drainage networks relationship is investigated. Secondly, direct current resistivity (DCR) soundings are acquired to characterize the subsurface layers distribution. The DCR soundings are inverted applying non-conventional inversion scheme to reduce the uncertainty of the DCR inversion problem. For subsurface lateral wastewater flow mapping, electrical resistivity tomography method is performed applying the triple-grid technique using unstructured triangular mesh for 2D-profiles inversion. The results demonstrate that the integration of RS and geoelectrical data represents a pertinent approach to understand the wastewater flow paths in desert lands. Although the general wastewater leakage has the same streams flow path, the major wastewater pathways are mainly controlled by subsurface fault zone and shale layer distributions. Hence, the present approach can assess and predict the wastewater flow-related crisis events before they develop.
