Boundary conditions for flow computation in 2-D models
This work presents some possibilities for imposing boundary conditions for flow computation in 2-D models. Boundary conditions can be given as imposed unit discharges, free-surface elevation or a known rating curve. A frequently encountered situation is that only the total discharge through a cross-section is known, either from a hydro-meteorological station or as a result of a 1-D model. Taking this into consideration, imposing a known unit discharge implies making an estimate of its value knowing only the total discharge through the considered cross-section. This work proposes an algorithm for resolving this issue. The proposed algorithm was implemented on field measurements conducted on the Danube River.
