Water Catchment Activity

Today, Room 11 learnt about water catchments. We made a model of a water catchment that demonstrated how water flows over different terrain and the effects of vegetation on water quality.

Water flows from high ground (hills, mountains) to low areas, valleys, flats and eventually to the sea. All land that brings water into a particular river is part of that river’s catchment. Some rivers have smaller tributaries as part of their catchment.

The Whanganui and Manawatū and Rangitīkei Rivers all have several other streams and rivers which bring water to them and are part of their catchment.

Here are some photos of our water catchment and the water samples that we collected through the process...
