Try using tissue paper on a flat surface like a piece of cardboard. Label important things like the towns around the river and what kind of wildlife is there.
A scientist might use a physical model like a scaled-down replica of a river system to study the flow patterns, sediment transport, and erosion processes in a river. By observing how water and sediment behave in the model, the scientist can gain insights into the dynamics of a real river and make predictions about its behavior under different conditions.

You could use wire for the shape of the river and use plaster of Paris to fill it in. Then, you would paint it.

To make a 3D model of the human respiratory system aperture wire and paper machete can be used to make the different organs involved. Using pictures as a model is a good idea.
