A wide range of delta morphologies occurs along the fringes Young Sound in Northeast Greenland due to spatial heterogeneity regimes. In general, regime is related catchment and basin characteristics (geology, topography, drainage pattern, sediment availability, bathymetry), fluvial discharges associated load, processes by waves currents. Main factors steering Arctic into are snow ice melt precipitation catchment, extreme events like glacier lake outburst floods (GLOFs). Waves subordinate only rework plain forming sandy bars if exposure fetch optimal. Spatial gradients variability driving forces (snow precipitation) (amount coverage, characteristics) as well strong local influence GLOFs a specific impede simple upscaling fluxes from individual catchments toward total flux Sound.
