We find that Isfiye and Arqan samples are harder (in hand specimen) than expected of chalk, present slightly negative isotopic values, and in . At high tide, bars make the water shallow which often causes waves to break early. Coastal Landforms of Deposition | A Level Geography Offshore breakwaters are generally shore-parallel structures that effectively reduce the amount of wave energy reaching a protected stretch of shoreline. Foredunes tend to grow to around 5m in height and around 20% of the sand is exposed (this is down from around 80% of embryo dunes).
