About Rivers

All rivers follow a similar journey, they start at the source and end at the mouth or Delta where it reaches the sea or ocean.

upper-courseUpper course

The river begains at its souce high up in the mountains or hills.  to begin with the river does not have much power.  many small tributaries join it at confluences (meaning that it quickly gathers momentum) Although th eriver is shallow its speed means that it is powerful enough to erode rocks.  Often the rivers will have waterfalls in their upper course when their are layers of hard and soft rock. Overtime the waterfall becomes bigger and bigger.

middle-courseMiddle Course

In its middle course the river widens, deepens and travels more slowly.  becasue of the sediment that it is carrying, the river may look brown and murky.  At this point, the river flows through its flood plain (areas that are flooded when the river breaks its banks)

mouthLower Course

In its lower course the river is near its final destination, the sea or ocean!  During its lower course the river as at its widest and slowest.  The river now has less energy, therefore it drops the sediment that has been carried.  The fresh water of the river than starts to mix with the salty water from the sea.  Deltas and estuaries can form mudflats.  Mudflats can be important breeding grounds for wading birds and other wildlife.
