„Targului” river improvement - Campulung Muscel municipality area / Arges county
Short description:
The Targului River crosses the Campulung Muscel City along about 7.5 km. A major unbalance of the thalweg level, respectively a severe lowering-in, resulting in phenomena of increasing bank erosion has been found out on the regulated river sector of 2.4 km length. Several economic and social objectives are in danger of being damaged.
The regulation works consist in:
- Changing the profile of the cross section of the present river bed at the value of 17 m in width;
- Bank protection with reinforced concrete prefab slabs dry wall supported on a reinforced concrete beam;
- Bank protection with gabions (sand bags) and mattress gabions;
- The construction of 7 reinforced concrete bottom sills.
Services provided:
- Basic engineering.
- Complete topographic and geologic studies.
- Detail engineering of the regulation works for the protection of the constructions adjoining the river bed.
- On site supervision and commissioning.
Main technical data:
From the hydraulic calculations on the flooding in the area resulted a river bed 17 m wide, considered to be sufficient for the water flow, which means a decrease in the calculating flow transit and of the check one.
The 7 reinforced concrete bottom sills have the role of reducing the river bed slope, implicitly, the water flows speed, which means a decrease in the thalweg erosion. These sills were located evenly along the regulated river segment.
In the area with constructions very close to the river, the banks were protected by a 1,1.5 stable slope by two methods, according to the available space:
- 1x1x0.15 m reinforced concrete prefab slabs dry wall supported on a reinforced concrete beam;
- supporting wall with gabions 3x1x1 m in size, 2x1x1 m, respectively, and gabion mattresses 3x1x0.5 m in size, 2x1x0.3 m.
