 Druridge bay is located 47miles from Berwick, 10miles from Morpeth, 23.6miles from Newcastle. I have been asked to answer three questions about the sand dunes at druridge bay and the management of the park. Druridge Bay Country Park includes three miles of beautiful beach and sand dunes, as well as a 100 acre lake surrounded by woods and meadows. There is a wide variety in the landscape. The park concedes of beach land woodlands and a lake. The bay its self is about 5 miles long and the golden sands are preserved in areas that are near small villages. Whereas in certain areas the beach is left for man to trample all over it and destroy its natural beauty. This beach in the north-east is a gem of the east coast with its rolling dunes slowly decaying due to human activity. In this piece of work I will be answering three key questions that concern the welfare of the beach.


Key Question one

“how do the dunes at druridge bay compare with a model sand dune”


In this key question I am going to compare a model sand dune with the dunes a Druridge bay. I will also be comparing the vegetation found on the dunes at Druridge bay and what I should be expected to find on a model sand dune. The model sand dune consists of an embryo dune followed by a yellow dune followed by a semi-fixed dune followed by a fixed dune. That is what the dunes at druridge bay should be made up of.

Dune shape 

The dunes at druridge bay should be like a model sand dune but they are not. I will explain why they are not.

embryo dune is formed by sand being blown over the strand line which is a deposit of sea weed that has been washed-up. Forming a small dune measuring 1-2m. Once embryo dune is formed marrow grass starts to grow replacing seu couch grass.

yellow dune is the next dune in order. The yellow dune should be behind the embryo it is formed by sand being trapped behind marrow grass. Theses dunes can measure 10-20m high. The main reason though is that the wind blows it into this shielded area behind the marrow grass where it can sit undisturbed.

after a yellow dune is formed a semi-fixed dune forms. Sand is trapped behind the yellow dune blown over by the wind that is coming onto the shore. Any marrow grass that grows on the dune starts to die. The marrow grass decomposes to form humus. Plants are now able to grow in the humus because when it dies it deposits vital nutrients into the sandy soil therefore grass and other vegetation is able to grow in this sandy area.

a fixed dune forms after the semi dune is. The fixed dune is formed by sand deposited behind the fixed dune. the soil gets damper and richer here so many more plants can grow because there is less wind to dry out the soil and by this stage the dunes are coming to an end and the soil becomes more fertile and moister.

At druridge bay the dunes are much different 10m from strand line the angle of the dune is 5˚ with the angle being so small suggests that there is no embryo and that it goes straight to a yellow. After another 10m the angle increases to 8˚. After another 10m the angle of the dune dramatically increases to 36˚ at this point there is a yellow dune formed. After another 10m the angle is 6˚ at this point this is the peak of the dune. After another 10m the dune starts to decline -7˚, -9˚,-10˚, 0˚,-2˚, -11˚,-12˚,-20˚,5˚, -2˚,-2˚. At ...
