This study investigates the directional characteristics of momentum flux, τ, under diverse wind-wave conditions in the Bay of Bengal (BoB). Using high-frequency data from an eddy covariance flux system deployed on a moored buoy, we identify various cases of wind-swell alignment and their resulting τ directions, with emphasis on seasonal variations. During June-August (JJA), when winds and swells are generally aligned, τ lies b...

Accurate estimation of air-sea fluxes is essential for advancing ocean modeling, observational studies, and understanding air-sea interactions. To address this need, the Indian National Centre for Ocean Information Services (INCOIS) developed and deployed a Flux Reference System (INCOIS-FRS) onboard ORV Sagar Nidhi . This article provides an overview of the system, its components, data acquisition methods, flux computation tec...

Uma Oya, which has the highest watershed of the Upper Mahaweli discharges into Rantambe reservoir. Uma Oya may have been polluted as it drains a large portion of agricultural lands. A preliminary study was conducted from April to October, 2007 sampling six randomly selected sites to determine the status of water quality of Uma Oya as baseline data. pH, water temperature, dissolved oxygen, electrical conductivity and turbidity...
