MGrowa - Model data

Description

The grid maps of the long-standing water balance components contained in this data compilation are based on the grid cell-based water balance model mGROWA (Forschungszentrum Jülich), which uses climate, land use, topography, soil map and geological maps as input data. In mGROWA, the actual evaporation and the total outflow are initially calculated in daily resolution on the basis of the respective precipitation quantities and climatic influences (100 x 100 m). The water storage and seepage movement in up to 5 soil layers as well as possible capillary rise from the groundwater are taken into account. The calculated daily values are subsequently aggregated to months, years or longer periods (here 1981-2010, 1991-2020, 2011-2020). In the following, the total outflow is divided into different outflow components on the basis of the site properties (cf. grid map ‘Site properties for dividing the total outflow into mGROWA’). In addition to the grid maps of the actual evaporation, the total runoff and the site properties, the data compilation contains the grid maps of the runoff components urban direct runoff, leachate rate, intermediate runoff, drainage runoff, groundwater recharge and direct runoff. Long-term averages (1981-2010, 1991-2020, 2011-2020) are presented. A detailed description is included in the metadata for this data compilation (link). The maps of long-term groundwater recharge contained in this data compilation are identical to the maps of groundwater recharge also published as separate data sets ‘(net) groundwater recharge’. Included datasets (raster maps): Actual evaporation (evapotranspiration) Long-year averages (1981-2010, 1991-2020, 2011-2020) calculated by FZ Jülich (as of 2021) Total outflow Long-year averages (1981-2010, 1991-2020, 2011-2020) calculated by FZ Jülich (as of 2021) Location characteristics for dividing the total outflow in mGROWA estellen by FZ Jülich (as of 2021) Urban direct outflow Long-year averages (1981-2010, 1991-2020, 2011-2020) calculated by FZ Jülich (as of 2021) Leakage rate Long-year averages (1981-2010, 1991-2020, 2011-2020) calculated by FZ Jülich (as of 2021) Intermediate outflow Long-year averages (1981-2010, 1991-2020, 2011-2020) calculated by FZ Jülich (as of 2021) Drainage outflow Long-year averages (1981-2010, 2011-2020, 2011-2020) 1991-2020, 2011-2020) calculated by FZ Jülich (as at 2021) Groundwater recharge Long-year averages (1981-2010, 1991-2020, 2011-2020) calculated by FZ Jülich (as at 2021) Direct outflow Long-year averages (1981-2010, 1991-2020, 2011-2020) calculated by FZ Jülich (as at 2021)
