River opportunities
Living on a flood plain
"Floodplains provide a wide range of benefits to the ecosystem and community that include:
- Flood storage and erosion control–offer a broad area for streams and rivers to spread out and accommodate temporary storage of flood water, reducing flood peaks and erosion potential
- Water quality maintenance – reducing sediment loads, filtering nutrients and impurities, and moderating water temperature
- Groundwater recharge
- Biological productivity – providing fertile soils with high rate of plant growth and diversity, richer agricultural harvests, and healthier forests
- Habitat for a variety of fish and wildlife, including rare and endangered species
- Recreational opportunities – providing areas for active and passive activities, supporting the economic base
- Open space"

Living close to a delta
"Advantages:
-fertile soil for agriculture-the deltas can trap pollutants before they flow into the gulf
-sediment that is deposited in the delta does not become turbidity in the gulf
-they create wildlife habits"

Living close to a river
"So why do people live near rivers?
- The land on a flood plain tends to be flat, which is helpful for building.
- The river can be used for communications ;
- or roads/tracks can easily be made on flat land;
- The flat land makes growing and harvesting crops by machine easier;
- Water is available for irrigation; eg for rice growing (dev);
- Water supplies for domestic use/river for washing;
- Disposal of waste, either directly into the river or by using the river to remove the waste;
- Population pressure leaves them with no choice, as there is little land left;
- Fishing in river/food supplies;"
