Deciphering ecological effects of major catastrophic events such as earthquakes, tsunamis, volcanic eruptions, storms and fires, requires rapid interdisciplinary efforts often hampered by a lack of pre-event data. Using results of intertidal surveys conducted shortly before and immediately after Chile's 2010 Mw 8.8 earthquake along the entire rupture zone (ca. 34–38°S), we provide the first quantification of earthquake and tsunami effects on sandy beach ecosystems. Our study incorporated anthropogenic coastal development as a key design factor.

Beaches along most of the shorelines of the world, exhibit variations in their geometric form over different time scales in response to the prevailing dynamic forces due to waves, tides and associated currents. The periods and intensity of erosion and accretion alternate over time and are generally coupled to nearshore wave conditions. The nearshore parameters, viz. wave runup, wave setup and wave energy, have been evaluated during storm and normal conditions of SW monsoon (June-September) and NE monsoon (November-February) by empirical parameterization along the Visakhapatnam coast.

A special beach nourishment project to recreate the coastline has been introduced by the Coast Conservation Department (CCD) for the first time in Sri Lanka to combat coastal erosion, CCD Deputy Director (Planning) Gamini Hewage told the Daily News..
He noted that a one km coastal stretch from Palliyawatte to Uswetakeyyawa had initially been selected to carry out this project.
Under this project, sand pumped from the deep sea will be used to fill the coastline recreating the beach. This is done using a sand pump vessel.

PANJIM: Union Minister for Tourism Subodh Kant Sahai has said that issues pertaining to garbage treatment and lack of proper sewerage system need to be tackled as a mission such that Goa can proudly claim that it has the cleanest beaches in the world.

Sahai, who is in Goa for the 42nd International Film Festival of India, gave assurances to Goa Chamber of Commerce and Industry, that Centre will give every possible support in this direction.

The ruling Biju Janata Dal, which faces the allegation of facilitating land grabbing bids by party men, industrial houses bureaucrats — both serving and retired — has at last done some face saving exercise. It has restored 1,301 acres of prime land on Puri beach to government, nearly 65 km from here.

The recovered lands, the current market price of which is estimated to be `1,300 crore, were fraudulently transferred to private individuals by some revenue department officials in connivance with some top influential local politicians.

The residents of Chellanam are trying to overcome the fate of forever being on the fringes of development priorities by forming a project to tap the tourism potential of their village.

Ask Chennai's fisherfolk and they will tell you that the road to hell is built on stilts. Various Central and state government agencies plan to construct three controversial expressways on stilts in the coastal city. These roads will displace more than 1 lakh people — mostly urban poor — and create a 100 km maze of elevated expressways, all of which will be built over river banks and the city’s famed beaches.

In pursuance of the constant monitoring of the environmental impact of the oil spill at Mumbai, the Maharashtra Pollution Control the Board (MPCB) had taken water samples on Juhu Beach on 8th August and sent them for lab analysis.

Environmentalists say spill will affect mangroves

Authorities said on Monday that the oil spill from the bulk carrier mv Rak that sank recently is a minor incident, but environmentalists nonetheless said that its timing was a cause for concern, especially in the context of mangroves' ecology.
