What is gully erosion? Gully erosion is the removal of soil along drainage lines by surface water runoff. Once started‚ gullies will continue to move by headward erosion or by slumping of the side walls unless steps are taken to stabilise the disturbance. Repair work done in the early stages of newly formed gullies is easier and more economical than letting the problem go unchecked for too long. Large gullies are difficult and costly to repair. What causes gully erosion ? Gully erosion occurs

Personal statement A visit to the Giants causeway while holidaying in Northern Ireland in 2011 opened my eyes to the captivating subject of geology. Seeing 40‚000 perfectly shaped hexagonal columns gave me an insight into the rich volcanic history of our Earth and posed many questions which pioneered my interest in geology. My fascination of geology expanded further when it came to choosing my A-Level subjects; Geology‚ Geography and Environmental Science. I was then introduced into a wider spectrum

5 Types of Erosion Erosion is a natural process in which the Earth’s surface is worn away by wind‚ soil‚ or other geological occurrences. Erosion is responsible for many magnificent rock formations around the world‚ like Pigeon’s Rock in Lebanon‚ or in Meteora‚ Greece. There are five main types of erosion‚ all capable of reducing mountains to molehills during the span of a few years‚ or a few centuries. The first‚ and most common type‚ is water erosion. Erosion by water can occur

EFFECTS OF SOIL EROSION IN THE PHILIPPINES Soil erosion is happening everywhere in this world. Especially near the water area and maybe it is happening below where we stand. One my grandparents told me‚ that one time when they were young a typhoon with its devastating rain hit manila. Because they were near river‚ because of the heavy rain without warning the soil beneath their home collapse and their home was wash away in the river. And it said to be the cause of the collapse of the soil

LANDSLIDES Introduction The term ‘landslide’ includes all varieties of mass movements of hill slopes and can be defined as the downward and outward movement of slope forming materials composed of rocks‚ soils‚ artificial fills or combination of all these materials along surfaces of separation by falling‚ sliding and flowing‚ either slowly or quickly from one place to another. Although the landslides are primarily associated with mountainous terrains‚ these can also occur in areas where an activity

Fieldtrip focus 1. Introduction Hypothesis We know every river starts its journey from its source. In the upper course of the river‚ the channel is at a high above its base level i.e. its mouth. Thus the gradient is high. Due to the height‚ it has a lot of potential energy. So it uses this energy to reach its base level. So the process mainly at work is vertical erosion. Further it has got a lot of interlocking spurs. There is less lateral erosion taking place. So the bed load is composed of

Introduction Introduction: Aim: How do channel characteristics change with the long profile in the River Wandle? Background: In south – east England the River Wandle lies as a tributary to the river Thames running through south west London at 9 miles long. The names of the river and of wandsworth have been seen to derive from old the old English “Wendlesworth” meaning “Wendle’s settlement.” Rain falls on the North Downs‚ filters through the chalk and emerges on the spring line at the wandles

The Formation of Coastal Landforms Coastal landforms are formed in several different ways and can depend on several factors. The factors are things such as wind direction rocky type and fetch of the waves around the landform. These factors all contribute to create distinctive landforms. This essay will be identifying the ways in which these coastal landforms have been made Headlands and bays such as Beachy head on the south coast of England. Headlands and bays are often found on the same coastline
