Their implementation requires cooperation between water management stakeholders, reliable and accessible spatial information, and digital tools to process this data. In this context, this cumulative dissertation highlights the potential of open geodata and open source software for water management. In addition, the thesis presents a GIS training program developed and implemented as a measure for capacity building.
