In many regions of the world water supply of clean drinking water is not ensured. Often it is not due to the absence of sufficient water, but more because of a mismanagement of the available water resources. The water community came to the conclusion that a holistic water management approach is a promising concept to tackle these critical issues. In this respect the term of Integrated Water Resources Management (IWRM) was defined in the early nineties by the Dublin principles (Biswas et al., 2009). Within the frame of the funding priority IWRM the German Federal Ministry of Research and Education (BMBF) sponsors a project for a Sustainable Management of Available Water Resources with Innovative Technologies (SMART) in the Lower Jordan Valley involving partners from Germany, Israel, Jordan and the Palestinian Territories. In SMART all water resources are taken into account including so far not used resources like treated wastewater, artificially recharged groundwater and desalinated brackish groundwater.
During the first two project phases (2006-2014) a hydrogeological and institutional system characterization was performed (Wolf & Hötzl, 2011). Furthermore adapted water treatment technologies and integrated water management concepts were demonstrated on catchment scale on both sides of the Jordan River (Klinger et al. 2015). Within the third phase (2015-2018) the investigations concentrate on water management relevant clusters. The contribution at hand focusses hereby on the technical implementation of spring water monitoring systems and a managed aquifer recharge site (MAR) into an integrated water management platform in an urbanized area Jordan.
The analysis of time series recorded by a state of art monitoring system at springs in Wadi Shueib revealed a correlation of precipitation, turbidity, specific electrical conductivity and E.coli. These easy to measure and combinable parameters allow a prediction of contamination events before they arrive at the spring. This procedure is currently further developed to an Early Warning System (EWS) which will be directly implemented at the local water supply system.
Based on hydrogeological field investigations, a site for managed aquifer recharge was delineated in the Jordan Valley close to Deir Alla. An alluvial fan consisting of sand and gravel provides a storage capacity for 1 Mio. m³ of water. Based on the hydrogeological model a numerical groundwater flow model is used to define an adapted operation and maintenance model.
Both, the EWS and the MAR site will be introduced into a water management platform called WEAP that covers the catchment cluster. Based on the reference model set-up diverse water management options are developed and evaluated by the use of performance indicators, e. g. environmental water stress. This framework represents a supportive tool for a sustainable urban planning. Even though it is demonstrated at a cluster in Jordan, it is transferable to other arid regions in the world.
