Application of Novel Exploration and Monitoring Strategies for Sustainable Managed Aquifer Recharge Operation

Abstract:

Water scarcity and drought have led to a strong decline of water availability in many semiarid countries with resulting ecological and economic impacts. Managed aquifer recharge (MAR), e.g. river bank infiltration or storm water infiltration basins and trenches, represents a promising technique to replenish water resources, and in combination with awareness raising, is an important step towards sustainable water management. However, choice of type and positioning large scale MAR infrastructure is challenging as it requires a detailed understanding of the subsurface. Furthermore, MAR site maintenance can be time intensive and costly as effects, such as bio clogging or colmation can lead to a strong decrease in infiltration capacity. In our work we will show examples of successful implementation of novel strategies of MAR site characterization and monitoring on different scales.
