The project pertains the rehabilitation and reconstruction of roads, protection works and river/channel improvements in the Region of Quriyat, Oman, severely damaged by Cyclone Gonu.
Hayl Al Ghaf Area
Rehabilitation of Hayl Al Ghaf road, including new bridge cross the wadi Al Misfah (L=240m), new road embankments on both sides of Wadi al Misfah (Quriyat and Hayl Al Ghaf) and ancillary works
Protection of Hayl Al Ghaf road wadi crossing (bridge abutments, piers and road embankments) including river bed excavation (L=2’530m) and diking (total length L=1’600m)
Flood protection of the Quriyat National Road, including a new riverbed profile (L=6’300m), restoration of existing river banks and diking with related works (rip-rap revetments, gabions and retaining walls, total length L=6’635m).
Flood protection for the village of Hayl Al Ghaf (settled on the Wadi al Dayqah edge), consisting in a massive wadi side diking and the related riverbed excavation. Among the minor works planned, the project includes a new town’s water supply system.
In the west area of Quryiat a “canalization” of the wadi Al Majlass (L=6’500m) and a diking protection system (L=8’000) have been foreseen (L=610m), in order to avoid its wandering.
Road works, as Irish crossing, are designed as completion of wadi Al Majalass improvement and irish crossing rehabilitation.
Along the Ramlah-Daghmar road a new multispan viaduct (L=180m) have been designed on wadi Al Misfah and two new multispan viaducts on wadi Dayqah (L=210m and L=90m). The hydraulic intervention consists on a channel improvement/excavation and a couple of long dikes (L=7’800m) in order to limit river widening, even for important flow rates.
On the long coastal road between Dibab and FinsAlong several small to medium-size wadi have overtopped the road, so existing crossings have been renovate, provide new irish crossings (no.8) or culverts (no. 77) as far as to perform diking protection systems and road rehabilitations
