A total of 263 riverbed potholes were studied at five sites with Precambrian Chhota Nagpur granitic-gneiss, tonalite gneiss and sandstone under Permo-Carboni­ferous age of Gondwana rocks. Fluvio-hydrological, geospatial and statistical techniques were used to determine the diameter – depth dynamics on lithology with structural diversity of the Rarh region of peninsular India. The diameter–depth relationship is required for site-specific regional projects such as excavation, channel-bed dredging and dam construction, specially in the stability analysis of environmental and hydraulic engineering projects. The result shows positive correlation between diameter and depth of different sites such as circular, oval and elongated sculpted forms. Lithology and multidimensional structural elements accelerate the growth and enlargement of potholes on various riverbeds of the Rarh region of India.

Abstract


A total of 263 riverbed potholes were studied at five sites with Precambrian Chhota Nagpur granitic-gneiss, tonalite gneiss and sandstone under Permo-Carboni­ferous age of Gondwana rocks. Fluvio-hydrological, geospatial and statistical techniques were used to determine the diameter – depth dynamics on lithology with structural diversity of the Rarh region of peninsular India. The diameter–depth relationship is required for site-specific regional projects such as excavation, channel-bed dredging and dam construction, specially in the stability analysis of environmental and hydraulic engineering projects. The result shows positive correlation between diameter and depth of different sites such as circular, oval and elongated sculpted forms. Lithology and multidimensional structural elements accelerate the growth and enlargement of potholes on various riverbeds of the Rarh region of India.
