Abstract: Large drainage systems management usually lacks an integrated approach, while facing governance and institutional constraints, and is flawed by weak participatory planning and nonaligned private sector role. Improving the management of large drainage systems is even more important in the face of climate change, with pronounced drought and flooding events. The objective of this paper is to present the application of systematic analyses to ascertain better groundwater management of existing large drainage systems: detailed review of the drainage system design documentation, assessment of environmental conditions, evaluation of land use changes and investigation of user requirements. Application of mathematical modelling, followed by proposal of drainage system modernization through (re)construction of infrastructure, automatization, monitoring and accompanying data management system are then used to improve system effectiveness and efficiency. Paper presents case study of Pančevački Rit area which is particularly suitable since it consists of agricultural and urban zones and has a long history regarding protection from excess water. The numerical simulation model of Pančevački Rit, used to examine current drainage strategy, has shown that existing canal network, with density of 25 m/ha, and 7 pumping stations with the installed capacity 35.8 m3/s are not sufficient to protect total area of approximately 33,000 ha, mostly due to inefficient management. The results of mathematical model were then used to select acceptable groundwater engineering solutions, which will satisfy the protection criteria in the investigated area. Furthermore, introduction of advanced monitoring and data management system with corresponding computational tools would provide a significant step toward integrated water management and achieving the sustainability of the complex drainage system in future exploitation.
