The rainfall analysis has shown (Table 3) that prolonged dry spells occur during the 2nd decade of September onwards. The data were then processed to identify the maximum rainfall received on any one day (24hrs duration), in any week (7 days), in a month (4 weeks), in a monsoon season (4 months) and in a year (365 days period).

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. �j4A��D��dF�dj#-��$�)LJ 1 0 obj
