Document Summary
Figure 1: flowchart of the hbv model: from column g3 to j11, the list of parameters from the instructions of the assignment are listed. This equation states if the temperature (tmean(c)) is less than the temperature threshold, then the precipitation will be snow. Otherwise it will be 0, indicating it was not snow but rain, but it must be 0 in this column. The same logic was applied but with the condition that temperature is greater than the threshold temperature. It calculates the snowmelt rate using the formula provided: ddf*(t-ttr). The lowest value possible is 0 because if there is no snow, then there is no snowmelt rate possible. It takes the initial snow depth (38mm) and adds or subtracts precipitation depending on whether there is snow or not. If it snowed, then it adds to the snow depth. If it rained, it will be the snow depth snowmelt rate. For example, the first equation for column r is.
