on the 15 march otaki river recorded a flow (cumecs) of 5.7 metres. this time last year it was 19.3 metres. how many metres difference is that to the nearest metre?

19.3 - 5.7 = 13.6
= 14(to the nearest meter)
To find the difference in flow between the two recorded values, you need to subtract the flow from this year (5.7 m³/s) from the flow from last year (19.3 m³/s). Subtracting these two values will give you the difference in flow in m³/s.
19.3 m³/s - 5.7 m³/s = 13.6 m³/s
Therefore, the difference in flow between this year and last year is 13.6 m³/s.
