The production of flood hazard and risk maps is the last but key working package. Based on the guide lines provided by WP3 and the data of WP 5 the simulation process will be carried out by the partners in close cooperation. Flood hazard maps show inundated areas and information like inundation depth, flow velocity and direction. In local maps also dynamic processes might be displayed. An intermediate products is the water level. The simulation of the inundation areas will use a hydrodynamic approach. The scenario conditions defined in WP3 need to be represented by the simulation process. To reach the desired quality the calculation should be performed on a raster-resolution of at least 5m. The production process of flood hazard maps usually is an iterative process. Based on the hazard maps the risk maps are calculated, using damage models and land use data sets as well as statistical data. Finally the maps need to be produced and published in an attractive and easy readable way for stakeholders use (WP4). Using the established common methodology, Hungarian partners will make available for the Danube River Flood Risk Maps Atlas the flood risk maps developed under a national program.

Activities
act. 6.1. Processing of input data; different formats and projections of input data are adjusted. For vector data the conversation and integration process is comparatively simple. To compensate different formats, height and projection systems with a high error rate a high automation rate and strict quality management is needed. The goal of this activity is the campatibilty of all data for the total area.

act. 6.2. Processing a water level (1 or 2D models); the aim of this activity is the production of a water level for the complete course of the Danube. This should either be done by using a uniform model or at least by coupling different models (decided in the first phase). The output will be a georeferenced water level for the different recurrence intervals.

act. 6.3. Flood hazard map production; the maps show the inundated areas and optional additional information like inundation depth, flow velocity and direction (local maps also dynamic processes). The simulation will use a hydrodynamic approach. The scenario conditions defined in WP3 need to be represented by the simulation process. The flood hazard maps usually are produced an iterative process.

act. 6.4. Flood risk map production; The maps show the potential losses related to a set of events. The calculation is based on assets by land use and damage functions, adjusted for each land use data set. Damage functions are adjusted to the regions concerned. Also the number of people endangered has to be calculated. Vulnerable infrastructure, cultural heritage and industry have to be displayed.
