The course consists of 5 parts. In the first part, the student is introduced to the flood types, their natural and potential context, flood-vulnerable areas, constructive and non-constructive flood management measures and Flood Early Warning Systems (FEWS). The second part of the course describes in detail the issue of flood risk assessment with the analysis of Directive 2007/60 / EC on the preliminary assessment and management of flood risk and the preparation of flood hazard and flood risk maps. The third part presents the FEWS and their importance in flood risk management. The fourth and fifth parts present the hydrological and hydraulic, respectively, (integrated) mathematical simulation of floods by identifying flood vulnerable areas and preparing flood risk maps, using a series of software, such as HEC-HMS, HER-RAS and TELEMAC.
|Introduction to floods
|Flood types, natural context, potential context, flood vulnerable areas, constructive and non-constructive flood management measures, flash floods, Flood Early Warning Systems (FEWS).
|Flood risk assessment
|Directive 2007/60 / EC on the assessment and management of flood risk. Preliminary flood risk assessment. Preparation of flood hazard and flood risk maps. Flood risk management plans. Flood management measures: prevention, protection and mitigation. Preliminary assessment of flood vulnerable areas through GIS-based multi-criteria analysis method.
|Flood early warning systems
|New technologies in precipitation assessment for flood risk management.
|Maximum rainfall distributions. Rainfall curves. Development of design hyetograph. Loss estimation. Rainwater runoff. Synthetic unit hydrograph. Design flood hydrograph. Flood routing. The HEC-HMS software.
|Flood hydraulics Ι
|Rapidly-varied flow equations and their solution by finite difference method.
|Flood hydraulics ΙΙ
|Hydraulic Modeling and Flood Inundation Mapping using HEC-RAS and TELEMAC software and preparation of flood risk maps.
By the completion of the course, the students will be able to:
|Lectures combining active learning with project-based learning and research-oriented teaching.
|Presentations on the blackboard. PowerPoint slides. PC calculations with Excel.
|Computer and software use
|Problems - Applications
|Assignments (projects, reports)
|Elaboration of 4 projects in groups of 2-4 people and writing of the respective Technical Reports with recommended specifications (project based learning). The delivery of the Technical Reports of the subjects is obligatory. Students start the projects in the classroom, in personal computers, continue them and complete them at home. The Technical Reports are corrected by the teachers and returned.
|Presentation of the projects by the students and discussion.
