LCE have been appointed by Tulipamwe Consulting Engineers (TCE), who are specialist roads engineers, to assist them with the assessment of the hydrology and hydraulics of road drainage for a number of roads projects.
MR76: Kamanjab – Khorixas: Design for the Upgrading to Bitumen Standards (2017 – Ongoing):
LCE conducted a detailed assessment of the drainage along this road which entailed an assessment of the rainfall dynamics of the area, hydrological assessments to determine the rates of runoff expected for different return periods and an assessment of the hydraulic capacity of the 132 existing drainage structures (culverts). A number of additional locations where cross drainage should be provided (no existing drainage structures) were also identified. The hydraulic capacity of the four existing bridges along this road, at least three of which need to be widened with the upgrading of the road, were investigated in detail.

TR3/1: Grünau – Ariamsvlei: Road Preservation (2017):
LCE conducted a preliminary assessment of the drainage for selected areas along this road which are known or thought to be problematic, including a location where a rainfall event caused a wash-out of the road and railway line in February 2011. This entailed an assessment of the rainfall dynamics of the area, hydrological assessments to determine the rates of runoff expected for different return periods and an assessment of the hydraulic capacity of the existing culverts or drainage structures in the areas investigated.

TR8/4: Rundu – Divundu: Road Rehabilitation (2017):
LCE conducted an assessment of the drainage along this road which entailed an assessment of the rainfall dynamics of the area, hydrological assessments to determine the rates of runoff expected for different return periods and an assessment of the hydraulic capacity of the existing culverts or drainage structures in the areas investigated.
MR27: Keetmanshoop – Klein Menasse: Feasibility for Upgrading to Bitumen Standards (2017):
LCE conducted an assessment of the drainage along this road which entailed an assessment of the rainfall dynamics of the area, hydrological assessments to determine the rates of runoff expected for different return periods and an assessment of the hydraulic capacity of the existing culverts or drainage structures, including preliminary assessments of four bridges, two of which have experienced problems with flooding in the past.
