It takes time, effort and equipment to collect, so only a small amount can be gathered from a small area.
- 5
Which kinds of physical data could be measured in the field?

Channel width, depth and velocity, beach gradient, pebble size and roundness, soil moisture, air temperature and wind speed.
- 6
