Assessment of Land Suitability for Surface and Drip Irrigation Systems in the Northwestern Coast of Egypt.

Abstract

T HIS WORK aimed at the assessment of the land suitability for surface and drip irrigation systems in a part of west Matrouh area, northwestern coast of Egypt. For establishing this target, a digital elevation model (DEM) and SENTENAL-2 image were used for identifying the physiographic units of the studied area. The integration between satellite image and soil survey using Arc-GIS10.9 software was done to produce the different maps of this work. These properties were used for assessment the land suitability. The studied area have nine landform units, including coastal plain, alluvial plain, sloping area, escarpment, coarse valley inner, coarse valley outer, low piedmont, Moderately high piedmont and high piedmont. Thirty-one soil profiles were selected to represent these different landform units and described morphologically .Soil samples were collected according to the vertical variations of each profile for physiochemical properties and analyzed. Results of land suitability assessment indicated that, the studied soils could be categorized as suitable (S) and currently not suitable (N1) for surface irrigation. Marginally suitable soils (S3) covered nearly 64% of the total area, while the remaining area was occupied by moderately suitable soils (S2) and those of N1 class (31%). The most limiting factors are texture, soil depth, drainage and excess of CaCO 3 content. The land suitability assessment for drip irrigation system indicated that, the soils are highly suitable (S1) in 2% of the area, moderately suitable in 56% and marginally suitable in 42% of the area. This shows that,the drip irrigation is more benefit than the surface irrigation in this area.

Soil Maps Based on GIS and ALES-arid Model as Tools for Assessing Land Capability and Suitability in El-Sadat Region of Egypt

“…Using the ALES arid-model in arid and semi-arid regions facilitated the finding of the most suitable agricultural system to be adopted (Abd El-Kawy et al, 2010). Land assessment applied to assess the land capacity and land suitability for a specific use in different conditions, can be performed automatically by using ALES software and GIS technique (Abdellatif et al, 2021 andGouda et al, 2018).…”

Parametric Land Evaluation for Different Irrigation Systems in El-Bahariya Oasis, Western Desert, Egypt

“…The aims of land evaluation are the identification of adverse effects and benefits of land uses (Mahmoud et al, 2020 andAbdel Rahman et al, 2017) Geographic Information System (GIS) can be used as an effective tool in many agricultural applications such as cropland assessment for sustainable agricultural land use planning (Aldabaa & Yousif,2020). Abdellatif (2021) carried out an evaluation of the application of surface and Drip irrigation in the Matrouh area, northwest coast of Egypt, the results indicated that the system of drip irrigation increased the suitability of land by 31% compared to surface irrigation. The most limiting factors were texture, profile depth, drainage condition, and the ratio of CaCO3 in profile.…”
