Evaporation and Water Level in the Active Layer

A simplified form of Mcllroy's combination in the active layer. The excess of evaporation model was used to compute bihourly evaporation over summer rainfall input to a small basin led for a High Arctic site. The computed evapora- to a rapid cessation of streamflow, confirming tion values reveal diurnal and seasonal patterns the importance of evaporation in the water which show a close relationship with water levels balance of small arctic drainage basins.
