Everything we know about the Waitangi River
Erosion of Haruru Falls track...
The track is made of clay and when it is dry it crumbles and breaks of the sides and creates hollows in the cliff side and is not stable enough to hold itself up so it slips and creates dangerous cautions. Sydnee-Jo and Matire
Because of how strong the current was it would slowly loosen the clay the trees are dug into. The trees which are attached to the pathway will eventually come out of the ground and because there is a thin layer of clay the roots will only go a small distance into the ground and will be easier to come out of the ground and unstable for people to walk on. Sydnee-Jo and Matire
Sediment & deposition (rock/stone/clay mud)
the sand that we were standing on at the lily pond and the river were a mixture of mud stones and rock. grinded together to make small and weightless sand,
At the Lilly pond where you park is made of clay and hardened mud when you go down to the water the ground is a mixture of mud sand and rocks
At the waterfalls, when the clay get wet by rain or so forth, it gets unstable and when it drys, it crumbles making everything on top of it fall down.
The flooding made the river wider, that made the current slower and gentle.
After the flooding the river current slowed right down.
It was hard for the people on the boat because they went down the river,and that is where the current flowed the hardest.
the water gets farster when it gets narroer
Every single floating devise was floating slow down the river.
the water gets slower when it gets wider.
the current changed direction
it was fast right down the river but at the top it was slow and steady.
When the water waves rushed up against the clay it took bits of it off until a big chuck did.
When we put a sponge ball in the water the water current pushed the ball and it was off to a good start then it fulled up with water and slowed down.
the sand that we were standing on was a mixture of mud,stone,clay,shells,rock and sand.
The current was pushing our objects in a diffirent places so the first time we put our objects in the water the first time was 1:50 and our second one was 2:42.
One of the experiments that was taken used a foam ball for there flowting objects. It went well for the first attempt but the second and third always took a different course because of the weight of the object, and because it is full of water. Sydnee-jo and Matire
Current of the water course...
It was stronger down the river then up it.
the current went fast then slow
clay and mud are similar, just like stone and rocks are nearly the same, its just about the size.
when dirt turns into clay it becomes soft
