Formulas of Surface area and Lateral surface area of Polyhedrons LSA or Lateral Surface Area refers to the sum of the areas of all the faces of a three-dimensional figure‚ excluding its bases. SA or Surface Area- refers to the sum of the areas of all the faces of a three-dimensional figure. It also referred to as the Total Surface Area (TSA). ~~~~~~~~~~~~~~~~~~~ For Rectangular Prism LSA= P(h) *where P=perimeter of the base ; h= measurement of the height SA= 2B+ LSA *where

Importance of Rewriting Storm Water Regulations Danielle Nielsen Goochland High School Abstract This paper observes the negative and harmful effects of water pollution and storm water runoff on the environment and the surrounding community. The most common form of water pollution is sediment runoff. It then goes on to explain the research and effectiveness of Best Management Practices (BMPs) and their positive effects. BMPs are conservation practices that can preserve or improve the state

hydrograph has a short lag time‚ high peak discharge‚ and steep rising and falling limbs; a ’damped’ hydrograph is the opposite. Urban development is likely to make a river catchment more ’flashy’ and prone to flooding‚ because of rapid runoff from impermeable tarmac surfaces into streams. Hello MAtthew The shape of a hydrograph changes according to a number of controlling factors in the drainage basin. An example is the amount of VEGETATION / SOILS (INFILTRATION CAPACITY) LEVEL OF URBANISATION LAND

With the rising world population‚ we will need more food. Farmers will not be able to support the whole world with food supply. The USDA is conducting research on the cost if Atrazine is banned. "The costs of treating all surface water consumed by those living in the Midwest would be about $400 million annually. Banning atrazine would eliminate the need to incur these costs‚ but the costs to producers and consumers range between $517 million and $665 million." (USDA). The

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

of these rivers‚ the farming season is planned around the floods‚ rice is a main crop and requires large quantities of water. Also‚ when the river floods it leaves behind fertile silt. write about how soils‚ vegetation and climate influence surface runoff which influences flooding or water shortage in the stupid drainage basin.. 1. Flood - Like droughts‚ flood are a naturally occurring phenomenon. Flooding is a result of a temporary overflow of water that escapes its usual boundaries. While

All 44 rivers in Kerala are highly polluted due to inflow of untreated domestic‚ industrial wastes and agriculture runoff. Most of the industries are near the thickly populated riversides‚ often near cities and towns. There is no efficient water treatment system in industries and city municipalities. Pollution level in some of the sites is far above permissible limits. Close proximity of increasing numbers of leach pit latrines under varying soil conditions‚ late rite (midland) and sandy soils

In mathematics‚ the Klein bottle ([klaɪ̯n]) is a non-orientable surface‚ informally‚ a surface (a two-dimensional manifold) with no identifiable "inner" and "outer" sides. Other related non-orientable objects include the Möbius strip and the real projective plane. Whereas a Möbius strip is a two-dimensional surface with boundary‚ a Klein bottle has no boundary. (For comparison‚ a sphere is an orientable surface with no boundary.) The Klein bottle was first described in 1882 by the German mathematician
