Pevensey had 150 groynes and we would have had to spend half the original 30m budget replacing them - a budget required to last 25 years. This is Since 2002 the shingle embankment has been managed to a defined minimum width. Whilst everyone would like to see Pevensey defended to the highest standard possible, government has finite resources available for provision of sea defence and coastal protection. example.

Cliff regrading and drainage is especially useful when the cliff is made of clay or other material because this material erodes easily and can slip when wet. Ths cost of tool steel is dependent on many factors including the alloy content and the manufacturing cost. We try to emulate this natural lumpy behaviour so typically we might put 15-20,000m3 on to the beach in any one campaign, and we'll do two of those per year, putting for example 5,000 in the southern area, 5,000 in the central area, and 5,000 in the northern area. Once there is a concrete structure for waves to hit, far more water and beach will be flung into the air, only to be sent landward by gale force winds that usually accompany the bigger storms. places. moves along the coastline, thus widening a beach. fences that run at right angles to the beach. Their good points are that they are very effective, have a reasonably long lifespan and often have walkways along the top for people to walk along. Groynes cost 150-250 per metre. Rock groynes dont stop shingle movement and indeed sediments pass through rock structures much more than they do through timber ones.

What is the cost of groynes? the sea, and are designed to interrupt longshore drift and catch sediment as it Sea walls tend to have a long life-span and provide excellent defence where wave energy is large. The effect of groynes depends on their location and orientation in relation to the shore. What problems are caused by global warming? Our guide outlines the major factors that affect the cost of a seawall and includes an option for a free estimate. If no maintenance were done the beach would quickly erode and wave energy reflected from the concrete wall would probably increase drift rates causing the rate ofshingle lossto actually increase. However, they starve down current (or Once built however, they don't require as much maintenance as a sea wall. other component is the variable order cost which is a cost per unit .
