Abstract: Abstract The present study demonstrates the relationship between peak rainfall intensity (PRI) and maximum flood depth (MFD) for an urban catchment in Northeast India. To study the impact of land use (LU) change and the rainfall intensities on the flooding pattern of the urban study area, the inundation maps are prepared for different LU. Also series of historical rainfall events and rainfall intensities with different return periods have been considered for the preparation of flood inundation maps. MFD has been determined from the inundation maps for all the historical rainfall events and probabilistic storms. MFD and PRI have been related to different rainfall intensities. This relationship between PRI and MFD would serve as a readymade decision-making tool for instant estimation of MFD corresponding to a given PRI and thus aid managers and decision makers to manage urban flood problem. The relation between PRI and MFD shows an exponential trend. The ratio of MFD in 2011–2006 varies between 1.06 and 1.21. The average increase in MFD from 2006 to 2011 is 1.12, which is attributed to an increase in effective impervious area from 2006 to 2011.
