Description
Summary:This work reports the results of a study on the effects of an earth levee in flow depth and velocity reduction found by mapping the flood hazard for the baseline and Nature-Based Solution scenarios for one of the case studies of the H2020 Phusicos Project, namely, the Jorekstad site, in the town of Lillehammer (Norway). To achieve this target, the study employed various modelling procedures. These included climate, GIS, hydrological and hydraulic modelling structured in an integrated workflow. By running the FLO-2D model, the flooded areas were computed, and maximum flow depth and velocity were assessed by varying the return period with reference to different settings of the antecedent moisture conditions.
