List of Backwaters of Kerala

Estuaries are semi closed water bodies connected to the sea, within which seawater is measurably diluted by fresh water. Interaction of two chemically and physically different water masses gives rise to complex sedimentological process ,morphological response, biological process and chemical characteristics. The backwaters of Kerala are a unique ecosystem in Kerala wherein lagoons, lakes, canals, estuaries and deltas of several rivers meet the Arabian Sea. The backwaters are made up of over 900km of interconnected waterways, rivers, lakes and inlets.
