NEWMAP SITES IN EDO STATE

Of the several gully sites in Edo State, few have been selected for the first and second phase of intervention by NEWMAP. They are:

 Oshiobugie  Erosion Gully in Auchi : The Oshiobugie plain occupies a large are of land stretching from Warrake road to Auchi – Igarra Road in the town. The causative factor of the problem is the floodwater draining from the sloppy terrain, towards Orle River. Some of the roads street affected by the devastation, includes Hospital road, Egbeadokhai road, Slaughter road and host of road adjoining streets in the Oshiobujie plain. The magnitude and severity of the erosion devastation is such that if nothing is done to abate the nuisance now, the entire Oshiobugie plain will be washed away in no distant time in the next rainy season(s). The erosion gully, which has developed into several branches in the area, has damaged several buildings, roads and the main trapezoidal concrete drain in the town. The situation has resulted to a serious loss of lives and properties and has hindered the socio-economic activities in the area over the years. This Major Gully Erosion with Eight fingers span across several communities in Auchi .

Queen Ede :The Queen Ede Secondary School road gully site, Benin City occupies a large are of land stretching from Benin – Asaba road in the town. The causative factor of the problem is the floodwater draining from the sloppy terrain, towards Ikpoba and due to abrupt termination of drain by the contractor working along Benin –Asaba Express way. The road is affected by the devastation, including the adjoining streets in the plain. The magnitude and severity of the erosion devastation is such that if nothing is done to abate the nuisance now, the entire area will be washed away in no distant time in the next rainy season(s). The erosion gully, which has developed into a recess branches in the area, has damaged several buildings, road and the main concrete drain in the gully which was undertaken by the Federal Government. The situation has resulted in a serious loss of lives and properties and has hindered the socio-economic activities in the area over the years. This major and active Gully Erosion spanns over 2 communities (Ogbeson) .

Ekehuan Gully Site: The Ekehuan gully is located in Asoro community, Uzebu quarters; a Sub urban community in Egor Local government area of Edo State.

The gully (950 m in length) started over five years ago as a result of the inadequacy of the side drains along Ekehuan road and the diversion of all run offs from the slope running right through Ekehuan road from Agbomwonba through the University of Benin (Ekehuan Campus) and down to the culvert crossing the Ekehuan road into the current gully location. Originally, the site was a moat but due to excessive runoff into the channel, it started cutting both at the banks and floor.

Currently, it receives storm water from the Oguola, Ogida, Oliha catchment and the Benin Moat; run offs and the catchment flows across the road and discharge into the gully.

IBORE GULLY SITE : The Ibore site is located in Esan Central Local Government Area; , approximately 6 km to the east of Ekpoma – Auchi Road.

. A large erosion gully had grown to a depth of approximately 20m and caused the collapse of a main road and several buildings in the residential area of Ibore. The damage at Ibore is a direct result of the poor drainage system that is unable to cope with the peak flows.

Ewu Gully Sites :Ewu is located about halfway between Benin City and Auchi , just north of the Benin City – Auchi Road, also in Esan Central LGA. A massive gully developed near the lower part of Ewu town where the gully developed as a result of the road drainage, which collects flows from across the catchment and concentrates them at this point , together with an increase in hardened surfaces in the catchment , resulting in the increased peak flows..
