| Abstract: | The present paper deals with the calculation of peak flood discharge by two important hydrological models- ‘Rational Method’ and Manning Equation’ in Junbedia Jorh microwatershed near Bankura town of West Bengal. The study applied ‘IMD 1/3rd Rule’ for calculation of short duration rainfall from daily rainfall data and ‘hydraulic radius’ for calculation of Manning value based on data derived from the field by Auto Level and GPS survey. The result shows that the peak discharge of the jorh during its record rainfall of September, 2021 was 69 m3s-1 rendering the lower part of the catchment more than 12 hours of waterlogging. The Manning equation estimated the discharge at 45 m3s-1 with consequent nineteen hours of waterlogging. It is found that the results so obtained by model estimations have fairly matched with the questionnaire survey results in almost 240 households in the most flood affected area of the catchment. |
