6. Modeling
Within near-natural wetlands of broad spatial extent, most ecological dependencies and
management activities and strongly linked to hydrological processes. Among ecosystems of
the Biebrza Valley, groundwater discharge-dependent mires and riparian wetlands are
dominant types of habitats (Okruszko, 1991). In several parts of the wetlands hydrological
information was crucial for the decision on conservation or restoration activities. Therefore,
hydrological models have to be set up and aimed to compute either surface-water or
groundwater flow dynamics. In this regard, a number of modeling studies were applied in
the Biebrza Valley (Batelaan & Kuntohadi, 2002; Grygoruk et al., 2011; Kubrak & Okruszko,
2000; Querner et al., 2010; Swiatek, 2007; Swiatek et al., 2008).
To analyze hydrological processes on groundwater discharge-dependent mires (some)
models were set up on the basis of available computation algorithms (SIMGRO,
MODFLOW). Hydrodynamic surface-water models (fluviogenic models) are used to
analyze hydrological processes on riparian wetlands. Due to the complexity of the problems
which were analyzed these models were created and dedicated only to be applied in
