Abstract: Thirty-four sediment samples were gathered from El-Hamrawein Harbour area. The investigating area sediments are composed of 84.86% sand fraction. The gravel fraction ranged from 0.00 to 46.54% and averaged 6.71%. Mud fraction varied from 0.00 to 32.39% and averaged 8.44%. The majority of samples were gathered from deep depths of the area contain a significant amount of mud fraction. This is a result of landfilling and dredging in the harbour area, additional to phosphate ore shipment activities. The carbonate content ranged from 22.10% to 85.78%, averaging 63.43%, indicating impure carbonate content. The sediment's organic......

Abstract: The Pagal Nala landslide located at Lat. 30° 28' 29.00" and Long. 79° 28' 04.16" on the Rishikesh–Mana highway (NH-07) at Tangni in Chamoli district of Uttarakhand is a huge threat to both the Char Dham pilgrimage route and India-China border connectivity. The geologic setting of the region is part of the Berinag Formation of the Inner Lesser Himalaya, consisting of interbedded meta-basalt, quartzite, and limestone. Differential weathering of the lithologies and proximity to the Main Central Thrust (MCT) have caused structurally fractured and jointed rock masses. Geomorphologically, the area is situated in a slope and concave spur zone with comparatively steep slopes (30°–45°) and active gully erosion that aggravates during monsoon seasons. The......
