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

Kenneth R. Sagum May 7‚ 2013 FR1 NATSCI1 “Effects of Soil Erosion in the Philippines” The soil is among our most precious resources‚ yet we often take it for granted or destroy it by making it susceptible to soil erosion.

His motive is unclear in whether or not he is supporting or antagonizing the art of writing‚ but his theme is clear: writing is a power captured in a moment’s notice that‚ when unobservant‚ leaves too quickly to be remembered. He describes the whole event as a near fatal one metaphorically symbolizing

Soil erosion Soil erosion occurs when soil is removed through the action of wind and water at a greater rate than it is formed SOIL The soil covering the surface of the earth has taken millions of years to form and we must learn to respect it. Soil is formed at a rate of only 1 cm every 100 to 400 years and it takes 3 000 to 12 000 years to build enough soil to form productive land. This means that soil is a nonrenewable resource and once destroyed it is gone forever. If we disregard this‚ a

Soil Degradation The damaging process of soil particles being moved and cycled by water or wind is known as erosion. Soil erosion can occur anytime soil is bare or exposed and naturally removed by wind or water. This form of soil degradation is a natural process but it further elevated by human activity. Human disturbances of the soil allow for this process to happen more rapidly under natural conditions. According to the University of Michigan‚ whose geologist conducted a study‚ human actions
