Start a comparison study between two watersheds, counties, rivers, or sites.
Take a look at a individual watershed, county, river, or site across a timeframe of your choice.
2Multiple Locations. What Location?
Is the Upper White River have better WQI scores then the Lower White? Are there differences in Chemical tests between our northern and southern watersheds?
Do rivers in highly farmed counties have different inverts then those found in urban areas? Do highly populated counties have lower CQHEI scores?
Does a river in an urban area have a lower PTI then one that runs through a forested area? Does a river in a coal mining area have a lower php then one found in an rural area?
Do water quality get lower on a river as it moves through a city? Do streams get higher Dissolved Oxygen scores the closer to its source?
2Same Location Across Time. What Location?
Has your watershed's water quality increased or decreased through time?
Has your county's water quality increased or decreased through time?
Has a local river's water quality increased or decreased through time?
Has your site's water quality increased or decreased through time?
