I would like to simulate (calculate) groundwater level changes/movement in wetland area. I was looking in hydrus demos and manuals but without any result. I dont have any inputs data from both sides left and right (some groundwater inflow or outflow or some ditch or river on the side), only atmospheric datas, plant datas, soil datas and groundwater levels datas. So I would like to consider with vertical direction of flow. I imagine that I put all my datas (atmospheric,soil and initial value of grounwater level) to hydrus 1d/2d and the result will be the movement (changes) of groundwater level (table) in time. So I would like to compare measured and simulated groundwater level. I find in Example2 - Grass Field Problem that you put initial value to model but in demo I couldn’t find it, where is that value. I dont know if this is possible with hydrus1d/2d or some other mathematical model, but I would appreciate it if you could help me with this problem.

Any help will be apprecited.

I didn't find the right solution from the Internet.
