Geospatial Analysis of Frontal Himalayan Spring Hydrology
Frontal Himalaya region comprises of Siwalik sub Himalaya hills and its foothill piedmont zone between
altitude about 400-600m from mean sea level. Consequently this is a non-glacial hydrological regime. So natural springs are
the key source of water for the stream flows within river basins and constitute the main source of drinking water and
irrigation. Therefore, assessment and inventory on spring hydrology are essential for formulation of successful sustainable
development plans in the region. Keep in view this a model study carried out from Ramnagar Frontal Himalayan (RFH)
terrain through development and integration of multiple GIS modules. The results suggested that most of the perennial
springs exist along the thrust/fault planes and fluvial deposit areas and the most of the non-perennial springs exist along the
fracture/joints and shear zones. The water yield of these springs varies greatly but maximum rate was monitored for thrust
and fault controlled springs.
