FLOOD RISK ASSESSMENT AND MANAGEMENT UNDER DIRECTIVE 2007/60/EU: GEODETIC APPROACHES AND DIGITAL TECHNOLOGIES FOR EFFECTIVE PREVENTION

This article analyses the application of Directive 2007/60/EU on flood risk assessment and management, mainly focusing on the preliminary risk assessment and the methods for identifying and classifying areas with significant potential flood risk. It examines also various criteria and techniques for designing flood threat and risk maps as well as flood risk management plans. Special attention is directed at geodetic activities in the stage of preliminary studies in flood prevention, including digital terrain model of river valleys and creation of cross sections for hydraulic studies. It emphasizes the importance of the accuracy of digital topographic models and cross sections for successful flood management. The article proposes a systematic approach to effective flood risk management using geodetic and digital technologies in compliance with the European standards and Regulations.
