Dear Sir / Madam,
According to the basic principles of Hydraulics, Qupstream=Qdownstream+Qsideweir.
However, the continuity equation above is not satisfied in my model. The water surface profile in my model (figure 1) doesn't appear as it should be (figure 2). It acts more like an inline weir.
Would you please tell me the mistake I made?

Figure 2. The water surface profile of side weirs
Kind regards
