Diel variations of physic- chemical factors were investigated at BARAM (900msl) in Glacial fed Mountainous Goriganga River of Pithoragarh district, Uttarakhand, where Gossi Garh joins Goriganga River. In the present study, ambient temperature, water temperature, Dissolved Oxygen, pH, and carbonate alkalinity were found to increase during day hours which decreased during night hours. Free carbon dioxide (CO) was completely absent throughout the study period i.e. for 24 hours. Water temperature showed a positive correlation with air temperature and pH, whereas dissolved oxygen showed positive relationship with carbonate, bicarbonate and total alkalinity during the day and night hours. Moreover, a complex interaction of various environmental factors also plays an important role to decide the fate of diel variation of abiotic factors.
