- Abstract:
- The heat pulse signal is analyzed in a new way with the goals of clarifying the relationships between the variables in the heat transfer problem and simplifying the procedure for calculating sediment-water interface fluxes J. Only three parameters x0, λ and(pc)ll are needed to calculate J by the heat pulse data for this analysis method. The results show that there is a curvilinear relationship between the peak temperature arrival time and sediment-water interface fluxes; and there exists a simple linear relationship between sediment-water interface fluxes and the natural log of the ratio of the temperature increase downstream from the line heat source to the temperature increase upstream from the heat source. The simplicity of this relationship makes the heat pulse sensors an attractive option for measuring soil water fluxes.
