1. Development of flood estimation model for ungauged catchments

To compute the design flood in ungauged catchments, country has been divided into 7 zones and further into 26 Hydro-Meteororologcially homogeneous sub-zones and flood estimation models have been developed for each subzone.  So far flood estimation reports covering 24 sub-zones have been published.  The periodic revisions/updating of earlier reports are carried out whenever additional data are received.

2. Probable Maximum Precipitation Atlases

Precipitation associated with the physical meteorological upper limit is termed as the Probable Maximum Precipitation (PMP). The dams for which a high degree of safety is required are needed to be designed to pass the flood resulting from the upper limit of precipitation. The basic input for such type of study require the information of historical critical storm events that have been recorded along with their synoptic situation. To make such information readily available with the designers/ engineers, work has been put in by CWC & IMD for development of PMP Atlases that act as a source of readily available historical critical rainfall along with a generalized PMP estimate of different durations for any area.
