Describe how you can assess the health of a river.
Answers
To assess whether targets were being met, Liu et al. (2006) identified the following indicators of river health: minimum flow, maximum flood discharging capacity, bankfull discharge, floodplain transversal slope, water quality, wetland area, aquatic life, and water supply

A healthy river has temperature levels, dissolved oxygen content, salinity, turbidity, hardness, acidity, and alkalinity (water pH) that are all within a natural range for that river and its species.
Now days there aren't pure water. If we protect the river which makes it become more healthier.
There are many ways like:
1. At home and on the river, use biodegradable cleaning products and earth-friendly body products. All of that and chemicals get washed down the drain and back to the rivers.
2. When using your washing machine and dish washer, keep a full load as it uses less water due to the volume the clothes and dishes take up. Turn off auto-dry and open up the dishwasher to let the dishes air dry naturally.
3. Time your showers. At 5 gallons per minute, a 10 minute shower uses 50 gallons of water. If you drank 1 gallon of water per day, that’s 50 days’ worth of water down the drain in 10 minutes.
4. Turn off the water when you brush your teeth or fill a cup with water that you’ll use so that perfectly good water isn’t going straight down the drain.
5. Turn off lights when not in use and unplug chargers. Energy production requires water to cool thermal power plants and for extraction, transport, and processing in fuel production.
6. Participate in Meatless Mondays. Not only does it give you variety and creativity in your meals, it takes about 600 gallons of water to make a hamburger patty due to the amount of water used to grow feed crops and water cattle.
7. Pick up trash and litter and toss it in the recycling or garbage cans. Lots of trash is washed down storm sewers and back to the rivers.
