One of the critical segments of the Indian coastline currently being studied for its intricate hydro and sediment dynamics is the Konkan coast, which makes up the bulk of the Western Ghats. The study region focuses on the numerical modelling of the Goa, South Maharashtra, and Karwar coastal stretches. This work includes calculating sediment transport rates in the north Konkan coast's nearshore sections and the 2D coupled numerical modelling of hydrodynamics and sediment transport. Waves, tides, currents, and winds were taken into consideration. One month of post-monsoon simulations from mid-December 2018 to mid-January 2019 was performed using the model. It was discovered that the model findings were in excellent agreement with the data. Sediment circulation was found to be mainly in a north and cross-shore direction. The sediment transfer was evaluated between several depth contours, including 0–2, 0–5, 0–10, 0–20, and 0–30 m of water. Over 386 kms, the average sediment transport rate for the area between 0 and 2 metrres of water was roughly 4.75 Mm3/year. According to the model's findings, there is significant sediment movement between 10 and 20 m of water (133 Mm3/year). During the simulated period of post-monsoon 2018, it was discovered that the total sediment transfer throughout the coastline length between 0 and 30 m of water was about 144.5 Mm3/year.
