Integrated priority map for softening gains hydrological resilience

Integrated priority map for the softening profit ‘hydrological resilience’ is composed of three criterion maps: pluvian flood risk, potential soil infiltration and flooding problems. This grid map gives a score that is the result of the sum of these scores of the underlying criteria maps. This sum was again reduced to a score of 1 to 5. The areas with a maximum score of 5 show the highest softening gains within the theme of hydrological resilience. The hydrological system in Flanders has become very vulnerable because the hydrological processes have been artificially manipulated over time. This integrated hydrological resilience map contributes to the creation of the final opportunity map for softening gains (https://www.vlaanderen.be/data source/catalogue/opportunity map softening gains). In order to efficiently and effectively reduce the degree of hardening, it is important to gain insight into those locations that are most likely to soften the soil. In order to determine where annealing is most promising, the opportunity map of annealing gains (and assessment framework) was thus developed. The integrated priority maps – including this hydrological resilience map – show per parameter whether a paved site has a large or small impact on the environment and therefore has a large or small priority for softening. More information about the creation of all priority and opportunity cards and the final combination to the final opportunity card softening profit can be found in the final report of the study carried out on behalf of the Environment department: https://researchportal.be/en/publication/softening profit-weighting framework-and-opportunity map-part-1
