Data required for a coastal investigation- measuring methods.

may measure waves breaking at different point in the sea.- Meter stick- TimerWave frequencyTo establish whether waves were constructive or destructive as this determines erosion rates.Counting the waves breaking and timing a minute whilst countingYou may lose count of the waves at breaking point- TimerWeather conditionsTo find out the wind speed in km/h.Holding up an anometre in the rough direction of the wind.You may not have the anometre pointing in the right direction.- AnometreLong shore driftTo find out which way the long shore drift was moving on the day. This determines how the coastal erosion happens because higher long shore drift the more powerful the waves areBy placing a golf ball in the sea and measuring how far it has drifted every minute.Sometimes the ball comes back the wrong way and does not give an accurate reading.-golf ball-Measuring tape-TimerShape of beachMeasure possible erosion or decomposition of the beach. This will show that the waves Use ranging poles to measure the shape and height of the beach.Sometimes the beach might have dips and holes in it, this will affect the results.- ranging polesWind directionThis determines the fetch and consequently the amount of energy has. It also shows the wave height as stronger wind the more powerful wave. Watching which way the flags were flying through out different beachesNot very accurate because we didn’t use a compassNothing
