Rainfall Intensity for Sewer Design - Stage 2

Price: £250  

This research and its data products make use of a new Met Office 1.5km climate length model simulation of the United Kingdom. This is important because the model can resolve convective processes that produce the heavy rain seen in all seasons which affects the functioning of urban drainage systems. The data products are optimised for use in the planning of urban drainage networks and the analysis of surface water flooding.

The two data products, aimed at urban drainage and storm water management professionals are: 

1.            Estimated changes in design storm uplifts, covering three different regions of the UK.

2.            A time series perturbation tool that allows rainfall time series to be adjusted to reflect estimated future rainfall conditions.

Estimated changes to design storms show similar or higher changes to those currently used by the water industry - this could have significant impacts on the resilience of sewer networks in the future, triggering different adaptive responses to protect customers and communities from flooding. The time series tool allows analysis of future changes to the operation of combined sewer overflows (CSOs) and wet weather loadings on treatment plants. 

Note: The software tool for this project can be downloaded from the 'Supporting Documents' CD.
