Activities:

Seven main activities are planned for the cross-border river basin of the Drava within the framework of work package T3 – Drava River basin (common tools, models, maps and projects), as follows:

  1. Developing common tools – collecting data on the Drava basin

Within this activity, the following are planned: common and coordinated data collection (hydrological, meteorological, hydrogeographic, terrain, bathymetric, topographic, photographs, etc.), execution of measurements of transverse and longitudinal profiles of the main stream and agreements on project and other key flow values to improve joint flood risk management in the Drava basin in the future.

  1. Developing common tools – preparing a common and cross-border coordinated comprehensive flood protection study for the Drava basin

In the framework of this activity, a joint and cross-border comprehensive flood protection study for the Drava basin will be developed in cooperation with Slovenian and Croatian institutions competent for water management, which will result in structural and non-structural flood protection measures that need to be implemented in the Drava basin to reduce the existing flood risk in the long term and prevent the emergence of new flood risk areas.

  1. Developing common models – developing and upgrading hydraulic models of the Drava basin

In the framework of this activity, new hydraulic models for the watercourses in the Drava basin will be developed or the existing ones upgraded; these will be used in the preparation of comprehensive flood protection studies and the preparation of flood hazard and flood risk maps.

  1. Developing common models – developing and upgrading hydrological models for predicting floods in the Drava river basin

Within this activity, the hydrological model of the Drava basin will be developed and the existing one upgraded; this will be the basis for quality prediction of flood events and timely issue of forecasts, warnings and alerts.

  1. Developing common maps – preparing flood hazard maps of the Drava basin

Based on the data collected (hydrology, profiles, etc.) and new and upgraded hydraulic models for the Drava basin, harmonised flood hazard maps for flood hazard areas in the basin will be developed.

  1. Developing common maps – preparing flood risk maps of the Drava river basin

Based on the prepared flood hazard maps and the agreed methodology for presenting flood risks, harmonised flood risk maps of flood areas in the Drava basin will be developed.

  1. Preparing project documentation for structural flood prevention measures in the Drava basin

Within the framework of this activity, the necessary spatial, construction, financial, environmental and other necessary documentation will be prepared, as agreed, verified and harmonised within the comprehensive flood protection study for the Drava basin, for the implementation of structural flood prevention measures that will actually reduce the existing flood hazard, not only the flood risk.
