Hydraulic Radius Exercise
Hydraulic Radius Exercise
(adapted from - Geographyalltheway)
(adapted from - Geographyalltheway)
Task
You will prove
or disprove the following hypothesis:
Hydraulic radius
increases with distance from the source.
Complete the
following steps to help you prove or disprove the hypothesis:
1. Download each of the Excel documents -
one for each of the fieldwork sites.
2. Complete the necessary calculations for
each fieldwork site - some of the information can be found by clicking on the
site locations on the map.
3. Produce a table in Excel that brings
together the distance from source, velocity, discharge and hydraulic radius
data for all the sites.
4. Produce a graph to show how hydraulic
radius changes with distance from the source - be careful with your x axis
(distance from source).
5. Write a conclusion - how and why your
graph proves or disproves the hypothesis.
