Abstract (english)
In situ remediation is an effective technique to reduce risk caused by contaminated aquifers. However, low groundwater-flow velocity – typical in natural aquifers – hinders dilution, thereby reducing remediation efficiency. A possible strategy to overcome this problem consists of forcing the flow field by means of a geo-engineered system of alternate pumping. This work is aimed at investigating the coupled effect of geo-engineered unsteady flow and natural aquifer heterogeneity on remediation. Here we introduce an innovative analytical formulation to quantify dilution in 3D heterogeneous porous media under the effect of alternate pumping. Our solution relies on a simplified first-order framework, which limits the solution to point-like sources, weakly heterogeneous media, and slowly oscillating transient flows. Our results indicate that the efficiency of the unsteady flow field is mostly ruled by local-scale dispersion. Furthermore, we analyze several schemes of alternate pumping, thereby showing that inducing a forced rotation in the mean trajectory enhances remediation efficiency.
Abstract (croatian)
Sanacija podzemnih voda je uspješna metoda smanjivanja rizika uzrokovanog zagađenim vodonosnicima. Prirodni vodonosnici su obilježeni malim brzinama podzemne vode što otežava razrjeđivanje, a time i efikasnost procesa sanacije. Navedeni problem se potencijalno može riješiti prisilnim protjecanjem ako se uvede sustav izmjeničnog utiskivanja. U ovom radu će se istražiti povezani utjecaj takvog projektiranog nestacionarnog tečenja i prirodne heterogenosti vodonosnika na proces sanacije. Uveden je inovativni analitički pristup za procjenu razrjeđenja u 3D heterogenom poroznom mediju pod utjecajem izmjeničnog utiskavanja. Predloženo rješenje spada u klasu prvog reda, što ga ograničava na točkaste izvore, blago heterogeni medij i tranzijentne tokove sa sporim promjenama. Ostvareni rezultati su ukazali da je efikasnost polja nestacionarnog tečenja dominatno pod utjecaj disperzije na lokalnoj skali. Nadalje, analizirano je nekoliko različitih shema izmjeničnog utiskivanja, što je ukazalo da induciranje prisilne rotacije u srednjoj trajektoriji toka povećava efikasnost procesa sanacije.
