Tide synchronous abundance of total suspended matter (TSM), currents and hydrodynamic modeling during September of 1999 have been evaluated to decipher source to sink pathways in the macrotidal Gulf of Kachchh. Despite being located in the arid region with low rainfall (50 cm y sup(-1)) and insignificant fluvial input, gulf waters are enriched in suspended matter. The TSM distribution is highly dynamic and changes with prevalent tidal conditions. Generally, all along the northern flank, the gulf waters remain turbid irrespective of tidal conditions. Moreover, TSM is showing inland reducing trend in the inner regions of the gulf. We have also observed significant amount of suspended matter across shelf dispersal of TSM in the central region, particularly during low and high tide conditions. Derived from the spatial variations in TSM, prevalent hydrography and clay mineral abundance, an advection of flux of river Indus into the gulf by flood tide currents is deduced.
