A decrease in salmon population due to an increase in river temperature suggests that the salmon may be experiencing thermal stress, affecting their survival, growth, and reproduction. Warmer water can reduce oxygen levels, alter migration patterns, and increase susceptibility to disease, all of which can contribute to declining salmon populations. It highlights the importance of monitoring and managing water temperatures to protect salmon populations and maintain healthy river ecosystems.

The activity involves getting your team across a "toxic river" and you only have one pair of boots or something to step on that will get you safely across. The key to this activity is that the team must have members carry people over the "toxic river."

Dams actually increase soil erotion. They trap sediment that would usually flow down river and increased economic activity around a dam usually leads to deforestation, road building, and other commercial activity that increases erotion.
When a river is in flood (in spate) the extra volume of water means an increase in the force the water that can exert on the river banks and river bed. There is also an increase in the silt content of the water, which means that in the lower reaches, where it may be calmer, there is an increase in deposition of the silt.

The extra rainfall would increase the river's speed and erosion power. Such a river is classed as being in spate (a term for a sudden flood in a river). Such an increase could result in flooding, especially in the lower reaches, on what is the river's flood plain.

A river basin is an area of land where all the water not absorbed into the ground or evaporated into the air drains into one particular river. A tributary does not increase the size of a river basin because all a river's tributaries are already included in a river basin.
