Optimization of Retention Ponds to Improve the Drainage System Elasticity for Water-Energy Nexus

The purpose of this paper is to investigate the optimization of retention ponds for energy production by a low-head hydropower converter towards smart water grids and new flood adaptation solutions. Flood drainage systems are infrastructures essential in urban areas to control floods, which include retention ponds that can be used as innovative solutions adapted to climate changes and smart water grids to produce energy in a near future and to improve the drainage system elasticity. A catchment-scale water/energy management model is used for designing solutions by defining the characteristics of the urban area and the hydropower converters. The study area is based on Alcântara zone, in a district of Lisbon, a specific down-town zone close to the Tagus river, which has the backwater sea tidal influence. A solution based on the catchment of this area for extreme values of runoff induced by a significant climate changes event in these last years is analysed and then optimized in terms of energy production for different characteristic parameters. Finally, results are shown and discussed to reveal the most suitable solutions.
