    Flooding is natural disasters that cause by excessive rainfall or melting snow which leads to economic losses, human and social tragedies. In 2000 and 2012 there were floods in Wallington River with peak discharges that cause the river to burst its bank. Environment Agency predicted that the flooding in South East Hampshire will experience flooding in the future due to land use and management and climate change. Thus, an early and accurate flood forecasting is necessary for decision making with regard to flood management. Deduction and use of hydraulic parameters (e.g. water levels, flooding areas) from satellite-images may improve real-time flood forecasting models by comparing them with calculated parameters. In the report describe ISIS Software was built in 1D model to calibrate the flood in 2000 in the Wallington River and return periods flow. Two extreme flow cases were considered which is the return period of 1 in 50 and 1 in 100 years is then compared with Gumbel’s distribution. The aim of this study was to investigate the flooding issue in river Wallington and recommend sustainable measure. This report also describes the process of Whole Life Cost in Net Present Value of the options available in Sustainable urban Drainage System. This understanding is required to improve flood risk management strategies that contribute to sustainable development in Wallington, Hampshire.
