                      Agency for Nature, Environment and Consumer Protection of
                      North Rhine-Westphalia, Germany (LANUV) the mGROWA model is
                      applied, in order to simulate the water balance components
                      actual evapotranspiration, total runoff, direct runoff and
                      groundwater recharge at Federal State level.
                      mGROWA-simulations were performed in daily time steps for
                      the hydrological reference period 1971–2000 and in a
                      spatial resolution of 100 by 100 m. mGROWA results for
                      groundwater recharge and State-wide recorded groundwater
                      withdrawal rates have been used to assess the extent of
                      groundwater exploitation in NRW.New hydrological insights:
                      Simulated groundwater recharge levels are presented as
                      long-term annual averages and as long-term monthly values in
                      order to indicate the seasonal fluctuation of groundwater
                      recharge rates. Quantitative statistics indicate that mGROWA
                      enables the simulation of total runoff and groundwater
                      recharge without significant tendency of over- or
                      underestimation. Against this background mGROWA simulation
                      results are used by LANUV to support regional water
                      resources management, e.g. for determining the status of
                      groundwater exploitation in NRW. The majority of groundwater
                      bodies in NRW are at present not at risk of unsustainable
                      groundwater usage. A small number of groundwater bodies
                      along the river Rhine, however, have been assessed as being
                      close to unsustainable groundwater exploitation.},
