Abstract:

contents of the model
NAVMO2 is an areal-based precipitation-runoff-evapotranspiration model, which calculates the direct runoff of a catchment area, subdivided in max. 70 subcatchment areas. The runoff is calculated in the partitions direct-, inter-, and base runoff. The time resolution is one day where time series of every length can be applied. NAVMO2 calculates the snow cover development in winter and the discharge of a melting snow cover in a 2x2 km grid size according to temperature, sun duration, and precipitation. All this is done with additional information out of digital elevation models (topographic information) and remote sensing data (land use).
principles of the model
specially used algorithms for runoff-generation: distribution of precipitation: rasterpoint method; snow melt: modified snow compaction method; evapotranspiration: Penman in dependence on soil moisture; overland flow, interflow, groundwater flow: principle of linear storage; channel routing: translation-retention-method.
