DESCRIPTION:Managed aquifer recharge is becoming increasingly popular to se
 cure and enhance water resources through a variety of techniques such as r
 iverbank filtration\, aquifer storage and recovery or ponded infiltration.
  In the NASRI-project several investigations were carried out in order to 
 understand the key factors controlling the water quality changes that occu
 rred during bank filtration and artificial groundwater recharge in Berlin\
 , Germany.\nDifferent numerical modeling approaches have successfully been
  applied for physically complex situations and redox-dependent geochemical
  reactions at the Lake Tegel and Lake Wannsee test sites. Substantial prog
 ress was also reached in simulating transport\, sorption and degradation p
 rocesses (e. g. microcystin and bacteriophages) during column and enclosur
 e experiments at different scales. The modeling study of the Lake Tegel re
 charge site showed that at larger scale the redox processes are predominan
 tly controlled by seasonal temperature changes rather than transient groun
 dwater flow due to varying recharge rates. The influence of transient unsa
 turated/saturated conditions appeared not to be important for the behaviou
 r of the hydrogeochemical system on that scale. \nOverall this paper shows
  that a sound understanding and analysis of the key processes affecting th
 e water quality changes during bank filtration and artificial recharge of 
 groundwater could only be achieved when flow\, transport and reactive proc
 esses are considered simultaneously\, both in the field and during modelli
 ng.
