It would be felt from the time a significant change took place.Check for inconsistency of record is done by the double mass curve technique (based on the principle that when each recorded data comes to same parent population, they will be consistent.Thus older records are brought to the new regime at X.Gopal Mishra is a Civil Engineer from NIT Calicut and has more than 10 years of experience in Civil Engineering and Construction.

Before using rainfall records at a station for any analysis, the data has to be checked forMissing rainfall data can be estimated using the rainfall data at neighbouring stations.If the normal precipitations at the different stations are within 10% of the normal annual precipitation at station X, thenIf the normal precipitation at any of the m stations vary by more than 10% from the normal annual precipitation at station X, then is estimated by the normal ratio method asInconsistency would arise in the rainfall data at a raingauge station if conditions relevant to recording of rainfall at the station undergoes significant change during the period of record.
