    초록·키워드

    A pedological study was conducted to investigate the impacts of anthropogenic activities on the pedogenesis and morphology of Entisols induced by the construction of Al-Khoud recharge dam in a dry region of Oman. The study involved a detailed soil survey, pedons descriptions, investigation of landscape geomorphology, mechanical analyses, and examination of the mineralogy and micromorphology of the soil fabric using petrographic techniques, viz. SEM and XRD. Dam construction and ensued engineering interventions has resulted in distinct spatial differences in the topography of the soil landscape, topology of wadi surface flow, and the pattern and nature of sedimentations of the Entisols of the area. As a consequence, there was an alteration in dynamics of water movement (runoff-infiltration-evaporation) dictating the nature and type of the physico-chemical and pedogeneic processes, which ultimately influenced the evolution of these soils. The micromorphological and mineralogical data depict formation of a web-like network with narrow bridges of calcic materials between the soil grains. The calcic bridges observed in the Entisols of the Al-Khoud dam area were characteriz ... 전체 초록 보기
