Title L6 – Soil Permeability – Constant Head Test Introduction Permeability is measured in term of water flow through the soil in a given time. The soil permeability is a very important factor to study the behavior of soil in its natural condition with respect to water flow. The size of pore space and interconnectivity of the spaces help determine permeability‚ so shape and arrangement of grains play a role. Often the term hydraulic conductivity is used when discussing groundwater properties

Water and Soil Protection Soil Contamination: Soil contamination or soil pollution is caused by the presence of xenobiotic (human-made) chemicals or other alteration in the natural soil environment. It is typically caused by industrial activity‚ agricultural chemicals‚ or improper disposal of waste. The most common chemicals involved are petroleum hydrocarbons‚ polynuclear aromatic hydrocarbons (such as naphthalene and benzo (a) pyrene)‚ solvents‚ pesticides‚ lead‚ and other heavy metals.

Eco L: Soil Diversity Introduction Soil is an ecological system consisting of inorganic minerals (sand‚ silt‚ clay‚ and nutrients)‚ pore spaces‚ water‚ gases‚ organic matter‚ living organisms‚ and plants (Thien‚ 2002). The soil is said to be stable structurally and chemically thus is considered an outstanding medium for soil organisms such as bacteria‚ fungi‚ protozoa‚ nematodes‚ arthropods‚ and earthworms. The potential habitats of these soil invertebrates are the spaces within the surface

Soil is the layer of broken rock particles and decaying organic matter on the surface of earth‚ which is essential for the growth of plants. It comprises of all the necessary nutrients that aid the growth and development of plants and trees. There are different types of soils‚ each one of them varying in its nature and texture. While some soils are deep rooted‚ the others are present on the margin. They also differentiate in their color‚ as some may be red while others are black. There are various

Teens tend to have three major sleep concerns. One‚ they are naturally sleepier than younger children or adults. Two‚ they tend to get insufficient sleep during the week due to academic‚ social and recreational demands and try to make up for it on the weekend by sleeping late. Three‚ they have a delayed sleep phase‚ meaning they want go to bed later and sleep later than other age groups. Given late night activities such as text messaging and video gaming‚ this propensity can easily become a full

Three major systems of government are a unitary‚ confederal‚ and a federal system. A unitary system is comprised of one major central government that controls a number of weaker states. In this system‚ the weaker states have no power whatsoever over the central government. Two largely populated countries with a unitary government are the United Kingdom‚ and China. A confederal system is a system in which a number of slightly organized states hold a majority of the power‚ while the central government

Soil formation‚ or pedogenesis‚ is the combined effect of physical‚ chemical‚ biological and anthropogenic processes on soil parent material. Soil is said to be formed when organic matter has accumulated and colloids washed downward‚ leaving deposits of clay‚ humus‚ iron oxide‚ carbonate‚ and gypsum. As a result‚ horizons form in the soil profile. These constituents are moved (translocated) from one level to another by water and animal activity. The alteration and movement of materials within a soil

I am writing today to discuss the issue of coastal erosion and the proposed solution of beach nourishment. Coastal erosion has several causes‚ the most prominent being the breaking of waves against the coastline. While seemingly harmless‚ over time waves break away at the shoreline‚ leading to its reduction. Beaches are the one thing that protect coastal structures from such damage. They act as a line of defense for everything they surround‚ and are necessary for communities to thrive along the coast
