that about 86% of land area in western Ghats and 75% in the Konkan coast suffer from sever to strong soil erosion. Land degradation reduces the productivity of land and total loss to the state economy from soil erosion is estimated at Rs 30billion (Rural Development and water conservation Department‚ GoM) It is estimated that world’s 1/6th of have already been degraded by water or wind erosion. This has two important consequences; firstly‚ the reduced ability of society to produce sufficient food

My written report on coastal management will revolve around the main issue explored in our field trip which is the gradual erosion of the foredune on Collaroy beach‚ and its effects on stakeholders (incl. residents‚ developers‚ specialist groups). This report will also include the decision making processes considered by the management (both local and state)‚ as well as the descriptions

occurring at the Terrigal beach area are: * Erosion‚ which is effecting: * The Skillion‚ mainly the headland and rock platform‚ which is part of a preserved area of land known as “the Haven” which also contains the rugby oval. The man type of erosion that affects this is from the sea. * The sand dunes on the beaches. This area is affected by wind erosion as well as the tides if adequate vegetative cover is not present. The main type of erosion‚ from the sea‚ takes the sand from the sand dunes

lasted throughout the 1930’s. It affected everyone‚ farmers and consumers alike‚ in its path negatively. The Dust Bowl of the 1930’s was caused by four major factors: drought‚ climate misconception‚ poor land management‚ and most importantly‚ wind erosion. The first of the four major factors is drought. During the Dust Bowl and the 1930’s there were four major periods of drought. The first lasted from 1930 to 1931‚ the second occurred in 1934‚ the third in 1936‚ and the last period of drought lasted

The payback period for the project was 3.10 years‚ when considering the erosion of Rotterdam‚ this would increase to 3.46 years2. The net present value of Merseyside is £15.61 million and when considering erosion‚ the net present value is £11.37 million2. The internal rate of return is 33%‚ with the erosion‚ it is 28.2%2.

Plate Tectonics The forces that shape the earth begin beneath the lithosphere. Rock in the asthenosphere is hot enough to flow slowly. Heated rock rises‚ moves up toward the lithosphere‚ cools and circulates downward. Riding above this circulation system are the tectonic plates‚ enormous moving pieces of the earth’s lithosphere. [pic] Plate Movement Tectonic Plates move in four different ways. When tectonic plates come into contact‚ changes on the earth’s surface occur. 1. Diveregnt Boundary-

Types of erosion involved in this are abrasion/corasion‚ which is Rocks that are carried in the river grind and erode the riverside and bed. Some of the rock at the sides and bed of the channel are washed away. This type of erosion widens the channel through lateral erosion and deepens the channel by vertical erosion.

come to a few conclusions which will sustain the beach for many years to come. Whilst acknowledging the strategies in place‚ I graded their effectiveness and considered the human and environmental impacts. I investigated the issue concerning coastal erosion by doing some firsthand work at Collaroy Beach and Long Reef and by some secondary research. Some of the first hand work included calculating the slope of the sand and some of the secondary source included comparing old photographs with more recent

erosive power of waves To protect a coast from erosion‚ people have built seawalls in front of a cliff or along the coast. A seawall is usually made of concrete. It acts as a buffer and absorbs energy of breaking waves especially during storms where the waves are strong‚ thus protecting the coast. A seawall shields and protects the coast from the direct impact of the incoming waves‚ thus reducing erosion. However‚ a seawall may not protect a coast from erosion in the long run. As waves break against the
