Earth’s Continental Crust which sits upon Earth’s highest layer of geological area the lithosphere. Soil is actually nothing more but the remnants of the Earth’s Mountains and the life that has lived on this planet through the natural process of erosion and time on Earth. A good soil is said to be composed of 5 % organic material 25% Air 25% water‚ 45% of inorganic material which could be either sand‚ silt‚ or clay. Being almost a majority these 3 categories have a lot to do with soil’s relationship

Geography Rivers 1. The speed and volume of a river varies from place to place along a river’s course because of many reasons. In the upper course‚ the volume of water is low as there are few tributaries. In comparison‚ the volume of water in the middle course is higher as there are more tributaries supplying water to the main river channel. The volume of water in the lower course is the highest as the lower course has the most tributaries. However‚ many other factors will also affect the

factors‚ acting together or alone. Natural causes of landslides include: •Groundwater (porewater) pressure acting to destabilize the slope •Loss or absence of vertical vegetative structure‚ soil nutrients‚ and soil structure(e.g. after a wildfire) •Erosion of the toe of a slope by rivers or ocean waves •Weakening of a slope through saturation by snowmelt‚ glaciers melting‚ or heavy rains •Earthquakes adding loads to barely stable slope .Earthquake -caused liquefaction destroying slopes. •Liquefaction

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

4.5 Environmental Assessment: Forest Road Surface and Ditches Network One of the main objectives of this study is to investigate some intensity road characteristics based on ZEB1 LiDAR data. These intensity characteristics are the area with construction problems and the extent of the ditches network. As road construction problems here we consider the peaks and the depressions on the road surface that affect the transportation. In order to evaluate the flatness of the road surface we can make use
