how to create a loop in simulink for runoff model

i have data of one year and i need to calculate runoff for each day of the day and the equation is as follows: rainfall + storage - evaporation - infiltration = runoff for 1st day and

for second day runoff, equation changes as follows:

rainfall on 2nd day + infiltration of 1st day is storage of 2nd day - evaporation on 2nd day - infiltration on 2nd day = runoff on 2nd day

Hi Poornima

If you are asking how to implement a for loop inside the model, there is a "For Iterator Subsytem" to repeats the execution in a time step.

Are you having difficulty building the model itself? If you aren't sure where to start because you're not familiar with how to model in Simulink, I suggest you start with the Simulink Onramp tutorial (https://www.mathworks.com/help/simulink/slref/simulinkonramp.html) to quickly learn the essentials.

If you can give some more information on where you are facing difficulties in your model, we may be able to give you more specific help.
