The precipitation in mountainous region has higher spatial variability and the correlation r(s) between precipitation series recorded at two stations distant 's’ apart decreases with s at faster rate than in plain region. As such, a denser network would be desirable in mountains for the estimation of areal precipitation.

In this paper, the correlation approach to derive the variance of areal precipitation has been discussed and a procedure is outlined for evaluation of network density m respect of (a) flood forecasting events, (b) long term climatological purposes.

The scheme suggested has been illustrated for Beas catchment (area: 12509 km2) in Western Himalayas.
