Hydrogeological studies were undertaken in Garhwal Himalaya of Uttarkashi district; Uttarakhand to characterize the fractured; hard rock aquifer systems by inventorying cold-water springs; thermal spring and Key Observation Wells. Three major aquifer systems are identified in Bhagirathi valley along ChinyalisaurDunda-Uttarkashi-Bhatwari-Gangnani section. Spring discharge analysis has shown that spring magnitude and spring discharge variability are lowest in metavolcanics of Garhwal Group; whereas both of them are highest in slate-phyllite-quartzite aquifer system of Morar-Chakrata Formation. Anomalous seasonal discharge variation in selected springs indicates isolation of spring flow system from the atmosphere; which is correlated with regionally extensive thrust-fault system in Lesser ... view more»
