Abstract

Surface runoff is the water flow which occurs when soil is infiltrated to full capability; it is also the excess water, from rain, snowmelt, or other sources which contribute for the runoff. It is an essential constituent of the Hydrological Cycle. In peninsular India, Western Ghats is a major geomorphologic feature which divides the water between west and east flowing rivers. The Udyavara Drainage is the river which originates on the footstep of Western Ghats and flow down the steep scarp on the west and discharges water and sediment into the Arabian Sea. In this investigation secondary data of four major river/streams (see Table 1 for data and Source of data) have been used for empirical quantifications of runoff. The paper focuses on the computing of Udyavara drainage basin, which is a realistic estimation of runoff contribution to the hydrological cycle of Udupi Dist, South west Coast of India. The runoff has been quantified using Lacey’s formula (Reghuhath, 1996). The factor such as average rainfall, monsoon duration factor, catchment characteristic factor and temperature are used to enumerate the runoff. Studies have shown anomalously high Gradient Index value of Western Ghats. (GI=1188.00) by Raghavan and Sreedhar Murthy (1991). In case of Udyavara River the stream is typical of a low coastal plain stream with Low GI Value which has a direct impact on Ground Water and Hydrological Cycle of Udupi District Southwest Coast India
