|Title:||HYDROGEOLOGICAL AND VLF STUDIES OF SPRINGS IN EASTERN AND NORTH-EASTERN PART OF DABKA MICRO-WATERSHED, DISTRICT NAINITAL|
EARTH SCIENCE ENGINEERING
|Abstract:||Physicochemical behavior of natural spring waters varies from place to place depending on the lithology of the area, climate and the rates of weathering and erosion. Greater. rates of• weathering leads to more dissolution of ions into solution'form the surrounding.. rocks when the spring flows through them in surface.' or sub-surface conditions.' The chemical concentration of major ions in the spring samples is an indication of the surrounding lithology and defines the water quality, chemistry and is important for deciphering whether: it can be used for domestic and industrial purposes. Spring flows may originate in an area from sub-surface fracture or seepage zones which can be traced to the origination of the source. Interconnected sub-surface fractures enhance the flow rate in an area. The present study conducted in Eastern and North-Eastern part of Dabka watershed, North-' west of Nainital, Uttarakhand involves deciphering the physicochemical character and quality of the spring waters in the region. Geophysical methods using -electro-magnetic properties of conductive beds was used to interpret possible sub-surface anomalies and fracture'zones in-the region which may indicate water bearing reservoirs. ABEM VLF..Wadi-_instrument.was used- in the process to delineate the fractures and the conductive water .bearing- beds. 'Their structural concordance with the Main boundary Thrust passing through the southern part of the. watershed if established would increase the potentiality of finding more water reservoirs in the. vicinity. iii|
