Success Point IAS Academy, Ankit Bansal - Eligibility Criteria, RRB In the estuary, there is little precipitation throughout the year. For example, Konkan coast. Under pristine conditions these embayments, where sea water is measurably diluted with freshwater from the surrounding uplands, are naturally enriched with nutrients from the land and sea. The estuaries absorb these high energy events. Mathematically, this balance is expressed in a non linear differential equation. Estuaries have an important role in absorbing, trapping and detoxifying pollutants. For example, beaches critically need regular supplies of sand to avoid shore line erosion and even the loss of beaches.

It is strongly affected by tidal action. (E.g: Hooghly, Narmada, Krishna, Godavari, Pulicat etc.). We review the main ecological services across a variety of ECEs, including marshes, mangroves, nearshore coral reefs, seagrass beds, and sand beaches and dunes. Course, Foundation - estuarine ecosystems. The estuarine salinity field is determined by the balance between advection by the mean flow and turbulent tidal diffusion. The plants (like algae), which are available in the vicinity of estuaries, take up excess nutrients (e.g. Some of the major sea ports are also situated within many estuaries in India. Part of natural heritage: Estuaries are also important as part of natural heritage. One of the major routes through which this regulation takes place is via carbon sequestration. Course, Success Point IAS Recruitment Notification, TNPSC - Exam The western boundary of this estuary is not clearly defined geographically, due to the lack of a comprehensive definition of an estuary in general (Elliott and McLusky 2002). 100 Case Studies by S.

Answer Key, GPSC The major factors which impact upon the growth and distribution of organism in an estuary are its salinity and the amount of flooding. This has been postulated that estuaries around the world can help in meeting 7% of the world’s energy demand if energy is produced by using the salinity difference. Seawater then fills this sink-hole, creating an estuarine ecosystem. Estuaries with their wetlands, creeks, lagoons, mangroves and sea-grass beds are rich in natural resources including fisheries.

Critical role in Flood Control: Estuaries have an important role in flood control. Exam Notification, UPSC The estuaries have a multi-dimensional role and are vitally important. If the estuary is an open system, the tides play a significant role in diluting and regularly flushing out the waste that is carried into estuaries.
