Estuary: A Natural Filter Emphasis on A Mathematical Model of Pollution in Mandovi River

Abstract

An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it and with a free connection to the open sea.  These freshwater estuaries also provide many of the ecosystem services and functions that brackish estuaries do, such as serving as natural filters for runoff and providing nursery grounds for many species of birds, fish, and other animals. Estuaries are among the most productive ecosystems in the world. Mandovi River in Goa is one such important Estuary. A mathematical model is presented to protect the Ecosystem
