Dams are important because:
They provide water for domestic, industry and irrigation purposes.
Dams often also provide hydroelectric power production and river navigation.
Domestic use includes everyday activities such as water for drinking, cooking, bathing, washing, and lawn and garden watering.
Dams and their reservoirs provide recreation areas for fishing and boating.
They help people by reducing or preventing floods. During times of excess water flow, dams store water in the reservoir; then they release water during times of low flow.
The amount of LFG produced in a year from the calculations is 1.5768 * 10^8 cubic feet.
<h3>What is LFG? </h3>
The acronym LFG stands for land fill gas. It is a gas that is produced by the decomposition of biomass in a land fill. This gas can be burnt to generate steam. This steam is used to turn a turbine and generate electricity.
If 1 million tons of LFG is burnt in a day, then 365 million tons of LFG is burnt in one year.
1 million tons of waste produces 432,000 cubic feet of LFG
365 million tons of waste produces 365 million tons * 432,000 cubic feet /1 million tons
= 1.5768 * 10^8 cubic feet of LFG
