Computer Analysis of Water Flow Transition under Existing Conditions on a River Sector in the Range of a Bridge Structure.

The paper presents a 2D numerical modelling of water flow transition on a sector of Strei River in the range of the DN7 national driveway bridge at km.376+818, outside the built-up area of Deva Town (upstream of Simeria), Romania, in case of a special highwaters phenomenon. The considered synthetical hydrograph follows an exceptional hydrologic event that occurred in the last days of April 2000 on the studied river sector. The numerical simulation looks to estimate (reconstruct) the water levels evolution and velocity distributions under the bridge and on the influenced upstream/downstream river stretches.
