Urban water supply in Europe is vulnerable to weather extremes and their evolutions in the long term.

This report D10.2 describes water quality forecasts obtained in the project case studies: Segura Basin, Llobregat Basin and other sites situated in Spain. The water quality forecasts developed in the project will improve the actions included in the Drinking Water Treatment Plants (DWTPs) Water Safety Plans (WSPs), thus leading to safer and more resilient supply of drinking water.

We investigate how a very high resolution (≤3 km grid spacing) convective permitting regional climate model (CPRCM) can be used to provide information about precipitation and precipitation extremes for three regions covering Scandinavia, West-Central Europe and Southwestern Europe in today’s climate and in a climate representing a warmer world....

This deliverable reports on the application of a multihazard drought risk management tool in three pilot studies. One of the pilots is located in Spain and two of the pilots are located in The Netherlands. The methods used in the two countries differ. A description of the applied methods and the results are given. The risk profiles and conclusions that can be drawn from them are described. A comparison of the pilot studies is made, in which the differences and the implications of the differences are described.

The drought risk approach has not yet proven its use in management or operational advice. Based on the results of the three case studies, the method is promising.
