Delta is a wetland, where rivers empty their watar and sediment into another body of water. It is shaped like a triangle. The size, geometry and location of the receiving basin also plays an important role in delta evolution. Types of delta are following-
1- Fluvial-Dominated Deltas
2- Gilbert Deltas
3- Wave-Dominated Deltas
4- Tide-Dominated Deltas
5- Tidal Fresh water Deltas
6- Inland Deltas
7- Mega Deltas
