Evapotranspiration Impact on Diurnal Discharges in a Small Catchment

Popis výsledku v původním jazyce

This paper describes a new application of the Fourier series for a detailed simulation of runoff in a small catchment in dry periods, when the streamflow is significantly impacted by evapotranspiration, particularly during daytime hours. The catchment was considered as a dynamic system, in which evapotranspiration has an impact on the day night fluctuation of discharges. Measurements of these discharges were accomplished by a high resolution water level sensor attached to a V notch. In parallel, the free water evaporation and also the soil moisture content have been measured nearby. The paper describes three runoff recession episodes in dry periods. Using short time step measurements and calculations, it was not difficult to analyze the diurnal streamflow fluctuations as harmonic waves. An application of the finite Fourier series model (FSM) to a quasi-periodic hydrologic data series clearly shows how the actual evapotranspiration influences surface runoff from small catchments. The method was verifi
