Abstract: Design flood estimations are an important aspect of floodplain management investigation. The
following study was carried out to study the applicability and feasibility of dam projects in order
to assess and revise the hazard potential of the projects. The study area was the Narayanpur
Dam catchment of Yadgir district in Karnataka. Probable maximum precipitation value was used
as the meteorological basis as this is considered to be the most maximised precipitation value for
a particular region. The peak value obtained using HEC-HMS software with Digital Elevation
Model and Probable Maximum Flood as inputs is to be considered for design safety review of the
project by Central Water Commission. The opposing opinions on whether the historical data of
rainfall is enough in the meteorological consideration of probable maximum flood is still
debatable. Exhaustive climate projection models on micro-scale studies about the local climate
has to be carried out and then incorporated and reviewed for rainfall projections.
Key words: Narayanpur dam, design flood, climate change, HEC-HMS, PMP.
