Detection and Assessment of the Waterlogging in the Dryland Drainage Basins Using Remote Sensing and GIS Techniques

Abstract: Waterlogging and elevated soil salinity commonly develop in the cultivated and arable areas of the Sahara, particularly within closed drainage basins. Multi-temporal remote sensing data of the Landsat Thematic Mapper (TM) and Enhanced Thematic Mapper (ETM+) for the Farafra Oasis in the Western Desert of Egypt were collected and processed to detect land cover changes, cultivations, and the extent of water ponding and seepage channels. The Shuttle Radar Topography Mission (SRTM) Digital Elevation Model (DEM) has… Show more

“…neglecting groundwater flow impacts and assuming a continuous spatial autocorrelation of river network properties). Secondly, other geomorphologic indices could have been used for the same objective (El Bastawesy et al , ). Furthermore, we need to take into account the spatial autocorrelation observed between close watersheds, probably due to substrates and precipitation fields continuous in space.…”

“…The geomorphologic properties of watersheds condition the use of fresh water upon which human and natural ecosystems depend for their sustenance. Although many factors may constrain water fluxes, the pattern responsible for most of the flow availability should be accurately quantified (Rodriguez‐Iturbe and Rinaldo, ; Olden and Poff, ; Cudennec and Fouad, ; El Bastawesy et al , ); this step becomes even more difficult when hydrological systems are poorly gauged (El Bastawesy et al , ; Blöschl et al , ; Hrachowitz et al , ). To analyse flow paths is critical in developing countries such as Haiti, where a large population depends on the water resource, either for its drinking needs, for food production or for flood and erosion mitigation (Frelat et al , ; Shamir et al , ).…”

“…DEM was employed to offer varieties of data that assist in produced landforms map, soil types and hydrology information. Drainage networks and sub-catchment boundary of the studied areas were extracting from DEM in order to investigate the spatial relationship of agriculture fields and the catchment-drainage networks [17].…”
