Probable Maximum Flood (PMF): This is the flood resulting from the most severe combination of critical meteorological and hydrological conditions that are reasonably possible in the region. The PMF is computed by using the Probable Maximum Storm (PMS) which is an estimate of the physical upper limit to storm rainfall over the catchment. This is obtained from the studies of all the storms that have occurred over the region and maximizing them for the most critical atmospheric conditions.
Standard Project Flood (SPF): This is the flood resulting from the most sever combination of meteorological and hydrological conditions considered reasonably characteristic of the region.
The SPF is computed from the Standard Project Storm(SPS) over the watershed considered and may be taken as the largest storm observed in the region of the watershed.
Design flood is the value of the instantaneous peak discharge adopted for the design of a particular project or any of its structures. In addition to the considerations of the flood characteristics, frequencies and potentiality of the contributing drainage area above the structure, social, economic and other non-hydrologic considerations which are likely to have influence are considered in deriving a design flood.
The term "design flood" is used to denote the maximum flood flow that could be passed without damage or serious threat to the stability of engineering structures.
