Abstract

We used MODFLOW 2000, with the GMS v. 9.2 GUI, to developed groundwater models to investigate the effects of installing a single beaver-mimicry structure (BMS) using different restoration designs in varied hydrogeologic settings. Five BMR treatment configurations were simulated in each hydrogeological setting (a total of 18 modeling scenarios). These treatments included installation of a BMS that creates: (1) an on-channel pond (S), (2) an on-channel pond with seasonal reactivation of a side channel near the stream (NC), (3) an on-channel pond with seasonal reactivation of a side channel further from the stream (FC), (4) an on-channel pond with seasonal inundation of the floodplain (FI), and (5) an on-channel pond with seasonal filling of an off-channel pond (OC). Three versions of each modeling scenario were developed to simulate differing hydrogeologic settings, where the boundary conditions were defined to simulate a stream reach that was generally gaining (G), losing (L), or strongly losing (SL) within the model domain. These 18 models are stored here.
