Water Balance And Climate Change

(Model tools: mGROWA, GROWA)

In recent years, the deterministic water balance model mGROWA (Herrmann et al., 2015) has replaced the empiric GROWA model (Kunkel and Wendland, 2002) for simulating and projecting the water balance at state and river basin scale in Germany and the Mediterranean region, see Bender et al., 2017; Ehlers et al., 2016; Herrmann et al., 2017; Panagopoulos et al., 2018.

At its core, mGROWA combines grid-based simulation of soil water balance (evapotranspiration, leachate movement, irrigation control, runoff formation, etc.) in high temporal resolution (days) and high spatial resolution (e.g. 100m x 100m) with grid-based area-differentiated separation of runoff into direct runoff components and groundwater recharge based on the BFI-procedure implemented in the predecessor model, the empiric GROWA model (Kunkel and Wendland, 2002; Herrmann et al., 2009; Tetzlaff et al., 2015).

Water Balance And Climate Change

mGROWA model results find their practical use and exploitation mainly in (ground)water management planning at the state level (Ertl et al., 2019; Herrmann et al., 2015; Herrmann et al., 2021), in model chains to determine nutrient loading in large river basins and other administrative units (e.g., Schmidt et al., 2020; Wendland et al., 2020; Wolters et al., 2021), to determine potential irrigation needs in agriculture (Herrmann et al., 2016b), and to assess current and future groundwater droughts (i.e., periods of below-average groundwater recharge; Herrmann et al., 2016a; Herrmann et al., 2020).
