The depth of a well or swimming pool in your neighbourhood. How did you find out?
Methods to Estimate Depth:
Asking locals: Ask local residents or elders about well depths.
Depth markers: Look at depth markers displayed in swimming pools.
Rope measurement: Use a rope to measure well depth directly.
Stone drop method: Drop a stone and count the time until the splash to estimate depth.
Typical Values:
- Residential well: 10-30 metres deep
- Swimming pool: 1-3 metres deep
