Résumé
The current investigation aims to study the geomorphological and pedological characteristics including soil classification and land capability evaluation for soils in the area located at southeast of ELSadat city, Menoufia governorate, Egypt. Calculating soil available water using soil water characteristic curve (SWCC), testing and validating Van Genuchten (VG) model in simulating SWCC, developing regression equations to predict the expected soil salinity over time and land use/land cover change detection within 20 years are also carried out. The integration of Remote Sensing (RS) and Geographic Information System (GIS) techniques was used to perform this work. This work could be presented important information about the potentiality of land resources for proper sustainable agriculture of these soils. The interpretation of geomorphic map produced using RS and GIS technology indicated that, there are three main identified geomorphic units including eight landforms in this area. These units are Alluvial Plain (Depression, Low and High Terraces), Aeolian Plain (Low, High Terraces and Plateau) and Pedi Plain (Low and High Terraces). Nineteen soil profiles were selected representing these landforms. The land and site features are observed and registered. Most of soil profiles were dug deep down to 150 cm. Profiles were morphologically described, and then disturbed and un disturbed soil samples were collected representing the subsequent layers in each profile for integrated physical and chemical analyses. Also, some available irrigation water samples were collected and analyzed especially for land capability evaluation.
