摘要：
Rapid urbanization in developing cities like Guwahati imposes significant changes in hydrological characteristics, causing frequent flash floods, and water logging, which are further enhanced by impact of the changing climate. Hence, there is an urgent need of incorporating climate change impacts in design of urban drainage structures. In this study, future precipitation of Guwahati has been forecasted for the period 2006-2100 for GCM models ESM2G and ESM2M, considering RCP8.5 scenario. IDF curves were generated using these predicted rainfall series. Rainfall intensities for both models were found to be higher than that of observed data, ESM2G being the highest. The effect of this increase in intensity was analyzed on a mini-watershed in Fatasil Hill of Guwahati City. Under ESM2G and ESM2M, both peak discharge and sediment loss were found to be increasing from the watershed. This implies upgrading the drainage system, adapting climate change impacted discharge for hydraulic design.
