This document presents a study on large scale engineering geological and geotechnical mapping between Kham and the confluence of the Kali Ganga and Mandakini Rivers in Garhwal Himalaya, with an emphasis on landslide studies along the Kali Ganga Valley. The objectives are to map the geology, geotechnical properties, geomorphology, landslides and critical landslide zones, and conduct stability analyses and risk assessment. The methodology involves base mapping, geological mapping, geotechnical sampling, engineering geological mapping, landslide inventory, thematic mapping in GIS, stability analyses, and recommending preventative measures. The outcomes will provide insights into landslide mechanisms in the sensitive MCT zone, identify vulnerable zones,
