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.

Laterite From Wikipedia‚ the free encyclopedia Monument of laterite brickstones at Angadipuram‚ Kerala‚ India‚ which commemorates where laterite was first described and discussed by Dr. Buchanan-Hamilton in 1807. Laterites are soil types rich in iron and aluminium‚ formed in hot and wet tropical areas. Nearly all laterites are rusty-red because of iron oxides. They develop by intensive and long-lasting weathering of the underlying parent rock. Tropical weathering (laterization) is a prolonged

Aside from Benjamin Franklin‚ Oliver Evans could perhaps be considered as one of the most prolific inventors in American history. Throughout his life‚ Evans would go on to invent vapor compression refrigeration‚ various textile machinery‚ and perhaps his longest lasting invention‚ the high-pressure steam engine. His design would be used in locomotives that would become crucial to both the American and global Industrial Revolutions. Evans was born in 1755. Coincidentally‚ this was the same year

In fact‚ due to his documentary approach in photography‚ Evans belonged to the first generation growing up on photojournalism. The photographer also developed a series of sign collages: Outdoor Advertisements (1929) and Broadway (1930) (Epstein 2000). Such works were bringing over $100 per photo at those times; however‚ the Great Depression was on its way (Epstein 2000). Walker Evans’ career took off very quickly due to the photographer’s talent and charisma. In the early stages of his professional

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
