Water Quality Research Questions Research Notes
What is the parameter? (Write a complete description of it.
Flow Rate is it is the measure of cubic feet per second or gallons per second in a creek or river. Cubic feet per second is expressed: ft3/sec. Flow is a function of water volume and velocity. Stream velocity increases as the streams volume increases. Unless the volume of a stream is the same of the other stream they won't have the same Flow Rate.
How does it affect water quality?
Large, swiftly flowing rivers can receive pollution discharges and be little affected, whereas small streams have less capacity to dilute and degrade wastes. Stream flow determines the kinds of organisms that can live in the stream, some need fast flowing areas others need slow,
How is it measured?
What levels are good?
What levels are acceptable?
What levels are bad?
Flow Rate is measured in cubic ft. per second, or "ft3/sec". Good levels of ft3/sec depends on what lives in the stream. Bad levels are pretty much whats too fast for any fish, macroinvertebrates, ect. Acceptable levels also differ to whats is living in the stream, there really is no good/bad levels, it just depends what the things in the stream need.
How does this parameter affect fish?
How does this parameter affect humans?
How does this parameter affect vegetation?
Flow Rate affects fish VERY much, fish could be washed away, etc. Fish do need either fast streams or slow streams. Fast-moving streams generally have higher levels of dissolved oxygen than slow streams because they are better aerated. This affects humans because streams with a higher flow can wash away eutrophication, waste, etc.

wow, your blog seems very interesting and calm, Niclas. it shows that your a person who cares a lot about school and his grades, am i right? that's a good thing. beleive me, i'm one of those people too. but maybe try to show the other side of you that's not devoted so much to school. i'm pretty sure you don't just spend your whole weekend doing homework and not spending time with friends. blogging is to let both of those sides come out and make it fun and also let people know more about you. the way a blog looks says a lot about the blogger. try and make your blog show the side of you that's not as devoted to school.

Acidic and basic are two extremes thatdescribe chemicals, just like hot and cold are two extremes that describe temperature. Mixing acids and bases can cancel out their extreme effects; much like mixing hot and cold water can even out the water temperature. A substance that is neither acidic nor basic is neutral.
The pH scale measures how acidic or basic a substance is. It ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic, and a pH greater than 7 is basic. Each whole pH value below 7 is ten times more acidic than the next higher value. For example, a pH of 4 is ten times more acidic than a pH of 5 and 100 times (10 times 10) more acidic than a pH of 6. The same holds true for pH values above 7, each of which is ten times more alkaline—another way to say basic—than the next lower whole value. For example, a pH of 10 is ten times more alkaline than a pH of 9.
