Abstract
A complex hydrogeological study was carried out in the framework of the
CIVAQUA program organized by the Trans-Tisza Region Environmental and
Water Authority to provide the multifunctional artificial recharge of Great-Forest
in Debrecen, East-Hungary. Due to several decades of overproduction of
groundwater resources, the groundwater heads below the famous park area in the
heart of the city has decreased to 12-14m, causing significant destruction of the
valuable and protected surface ecosystem. The groundwater model of the
investigated area was utilized to investigate several technical solutions in order
to solve the severe water quantity deficit of the park. The source of the
infiltration recharge is provided from near-site surface water bodies, which raises
inevitable issues concerning the groundwater quality. In addition to the urgent
need for finding appropriate recharge alternatives, the environmental authorities
are aware of the slow mobilization of a complex hydrocarbon groundwater
contamination from an adjacent industrial complex of the city. The contaminant
plume was proved to evolve in the direction of the waterworks wells. The
hydrodynamic and transport modeling aided planning has to give answers to
several questions of a complex groundwater quality and quantity problem of this
major city in Hungary. The modeling aided concept wanted to find a carefully
designed artificial recharge strategy that serves the reconciliation of ecological
and drinking water demand, but at the same time forming a hydrodynamic
barrier in the way of the contamination plume.
Keywords: hydrodynamic and transport modeling, overproduction, artificial
groundwater recharge, groundwater quality problems.
