Quality standards used for audit purposes include those set by a company or by the American Society for Quality or ASQ, International Standards Organization or ISO, American National Standards Institute or ANSI, six sigma quality standards and military specifications or milspec. Audits can also be divided by the type of auditor.
All rivers are surrounded by a certain amount of land that is higher in altitude (upgradient) than the actual river. Precipitation that falls in this area eventually flows downhill towards the river. At any particular point on a river, the land upgradient of the point is the river's watershed, or drainage basin.This example of a watershed gives a rough idea of how precipitation flows downhill into rivers (and lakes). What separates two watersheds from each other are ridges of higher land.ll rivers are surrounded by a certain amount of land that is higher in altitude (upgradient) than the actual river.

Precipitation is a major component of the water cycle, and is responsible for depositing most of the fresh water on the planet. Approximately 505,000 km 3 (121,000 mi 3) of water falls as precipitation each year, 398,000 km 3 (95,000 cu mi) of it over the oceans.ixtures of different types of precipitation, including types in different categories, can fall simultaneously. Liquid forms of precipitation include rain and drizzle. Rain or drizzle that freezes on contact within a subfreezing air mass is called freezing rain or freezing drizzle.
