What is the main force that directly causes the deposition that continually change the coastline of Texas?

The main force that directly causes deposition along the Texas coastline is the action of waves and currents, primarily driven by wind. As waves break on the shore, they transport sand and sediment, which can accumulate to form beaches, dunes, and other coastal features. Additionally, river discharge and tidal forces contribute to the sediment budget, influencing deposition patterns over time. This dynamic interaction of natural forces leads to the continuous reshaping of the coastline.
