“…Soil morphology is affected by climate, land use, farming systems, and seasonal variations (Suther and Leigh, 2020). Generally, soils are studied for their morphology at an appropriate moisture level between field capacity and permanent wilting point for better visualization and understanding of the pedogenic processes.…”

“…Many pedo-morphological properties, such as color value, root abundance, and structure, are dynamic and influenced by land use type and management (Suther and Leigh, 2020). Studies have emphasized to use the pedo-morphological properties for land and soil quality evaluation (Juhos and Madarāsz, 2016;Suther and Leigh, 2020). However, most of the soil quality studies have only used the soil physical, chemical, and biological properties, ignoring the pedological context for the soil quality evaluation (Suther and Leigh, 2020).…”

Suitability analysis of groundwater for irrigation purposes is also necessary for suggesting optimal planning measures because the groundwater is being increasingly used for agricultural production in semiarid regions (Elwan, 2013).…”

The study shows how to use cutting-edge geospatial technology to better assess desert resources and provides a systematic approach that can be used elsewhere under the same conditions. A total studied area of 19320 Faddan in Wadi El-Amal located in Aswan governorate, Egypt. This study area is a desert; however, haphazard planning, management practices, and inadequate investments result in land and water resource degradation. The pedomorphologial, physical, chemical, fertility characteristics of the selected soils were studied based on in-situ, remotely sensed and other data sources. Data on water geochemistry of water samples, collected from three dug wells were also utilized for this study. Five soil mapping units (SMUs) were prepared based on soil depth, rock fragments intensity and size, soil texture, and land topography. The SMUs are: (i) deep moderately fine textured soils with almost flat topography (4760 Faddan; 24.64%), (ii) deep gravelly medium textured soils with gently undulating topography (4740 Faddan; 24.53%), (iii) moderately deep gravelly coarse textured soils with gently undulating topography (3350 Faddan; 17.34%), (iv) shallow cobbly coarse textured soils with undulating topography (2900 Faddan; 15.01%), and (v) very shallow stony coarse textured soils with undulating topography (3570 Faddan; 18.48%). Different evaluation methods were utilized to characterize, evaluate, and plan the studied lands based on the collected data related to soil, water, environmental, political, and socioeconomic criteria. Three different evaluation methods namely qualitative desert land potentiality evaluation (Q L DLPE), the American land capability classification (USDA LCC), and qualitative desert land aptness for crops (Q L DLAC) were used to implement assess the potentiality and capability of the studied lands to produce various suitable crops. Q L DLPE model has grouped the study area into four potentiality classes (high, moderate, slight, and low) while the USDA LCC system classified the study area into three capability classes (class-III, class-IV, and class-V). The characteristics of each soil unit were compared with the requirements of major crops of the study area and suitable crops for each unit were identified. Six land utilization types (field crops, vegetables, citrusfruits, oil crops, forages, aromatic plants) were suggested as value-added crops for cultivation following the precision farming technique. The results of the evaluation analyses were integrated to propose a sustainable plan through integrated desert land use planning (IDLUP) methodology. Accordingly, about of 66.51% of the total study area (12850 Faddan) was determined for agricultural development, while the rest area (33.49%) was excluded from the agrarian expansion and may be used for the housing and constructions. Value-added crops were prioritized as follows: Field crops and vegetables (4760 Faddan) > citrus-fruits and oil crops (4740 Faddan) > medicinal, aromatic plants, and forages (3350 Faddan). The findings suggest strategies for c...

“…It is therefore not known how, and if, Piedmont alluvial fan processes are influenced by basin size, climate change or rock type similarly to their arid counterparts. In addition, while anthropogenic gullying in the Piedmont has been long recognized (Costa, 1975; Daniels, 1987; Spell & Johnson, 2019; Trimble, 1974), older records of Piedmont landscape evolution, which include features such as these fans, have generally been overlooked with only a few exceptions (Arey, 2018; Layzell et al, 2012; Leigh, 2008; Markewich et al, 1990; Mills & Allison, 1995; Pavich et al, 1985; Richter et al, 2020; Suther & Leigh, 2020). Thus, Piedmont alluvial fans represent a potential resource for understanding Piedmont landscape evolution overall.…”

We describe the soils, stratigraphy, distribution and ages of alluvial fans in the North Carolina Piedmont to understand factors contributing to their formation in this low relief, humid‐temperate setting. We find that those contributing factors (i.e., contributing source basin area and rock type; and climate) parallel, but do not precisely mimic those of arid and semi‐arid climate fans. Digital elevation model (DEM) and field observations revealed that about 25% of 209 mapped basin outlets contain alluvial fans. Fans are all < 0.01 km2 in area, with a contributing basin area threshold of ~0.1km2 above which fans are not commonly observed. Fans issuing from basins underlain by more easily weatherable and erodible argillites are generally larger than those that contain more resistant rhyolites. Radiocarbon dates of fan sediments are dominantly late Holocene (13 ages < 3000 ka; two ages between 7000–10,000 ka), with notably no late‐Pleistocene aged fans. We thus infer that fan aggradation is predicated on watershed characteristics – and climates – that favor high sediment supply to discharge ratios. Detailed soil and sediment descriptions from pits located on 15 fans reveal that approximately half exhibit cumulic over‐thickened soil profiles forming dominantly in sheetflood deposits, providing evidence of ongoing, relatively slow deposition. Low iron ratios measured from those fan soils suggests recycling of more developed soils from basin hillslopes. Occasional matrix‐supported debris flow deposits in some fans provide evidence of much less common, rapid (0.5–1 m) fan accumulation. While acknowledging a paucity of detailed climate records in the Piedmont precludes identifying precise mechanistic relationships, our mapping, soils and sedimentologic data suggest that climates favoring modest hillslope erosion without extreme runoff lead to periods of fan aggradation in this transport‐limited landscape. Overall, this work documents significant rock‐type modulated, climate‐driven Holocene landscape evolution in the south‐eastern US Piedmont predating legacy sediment erosion and deposition that has gone largely underappreciated.
