EDITORIAL: Experimenting criteria for risk mitigation in fluvial-coastal environment

The article analyzes morphodynamic aspects of dam-river-coast system and the related conflicts. New tools are required for the study of this system, with the aim of defining in the medium-short term river longitudinal zoning, concentration time evaluation and return time, catchment erosion rate, quantification of silting of reservoir, littoral drift and morho-evolutionary trend of littoral prism. The proposed systemic approach aims to select adaptive rather than maladaptive strategies, following a policy of forecast, prevention and protection. Ecological engineering techniques and environmental design are fundamental to mitigate risks, recover and remediate endangered transition environments, considering integrated interventions in dam-river-coast system based on resilience rather than resistance.
