[ad_1]
The map and aerial photo cover part of the Columbia River valley in south-western BC, a relatively short distance downstream after it has flowed out of the Rocky Mountains.
1)What name is given to a river system with the characteristics visible in this map? (Note that there are multiple channels.)
2)The river flows from the north-west to the south-east. What type of feature could potentially form within the area marked by the red dotted oval, if this particular channel is subjected to energetic high flows at some point in the future?
3)Provide three separate characteristics / features of this type of system which help it to absorb and withstand unusually high flows
