boundary condition in down stream needs data about water level as a fuction of time. how can i do if i dont have that information?, cant i let with out data that boundary condition ? or can i to assign a value like cero or a value close to level from the topography. in others similar software of modeling i just needs define free flow or slope condition and eventualy a hot start running

What kind of calculation are you performing? Bed material load calculation? Flow only? Debris/Mud flow calculation? For the flow only and bed material calculations, normal flow depth can be used, if you don’t have data. For Debris/Mud flow calculation, you don’t need to set the water level data at the downstream boundary.
I am building a bed load modeling, and my ask is: in boundary down stream, the value that I need is the water surface level (wsl) from datum, of my topo data, or simplely water depth in this boundary?. thank you for answer.
do you know how to set the a laterally migrating upstream inflow point ?
