  4. The Flood Disaster Very heavy rains in December 2010 and January 2011 caused extraordinary runoff that made rivers overflow their banks in a small, land-locked country in Southern Africa A Government-led post disaster needs assessment revealed that physical assets were destroyed, production was reduced and higher costs were incurred due to the flooding, to an estimated amount of 463 million LCU, or its equivalent of US$ 67 million In the road transport sector bridges and culverts were destroyed, long road sections sustained deterioration of road carpeting, road traffic was briefly interrupted in some urban areas, and higher transport costs were incurred RJ

  5. Damage and Losses inRoad Transport Sector 30 % of total disaster effects RJ

  6. Road B-24 connectingMapoteng and Teyateyateng RJ

  7. Traffic flows in Road B-24 RJ

  8. Culverts Destroyed in Road B-24 RJ

  9. Culvert destruction andtraffic re-routing Longer distance: 38.8 Km Time for reconstruction: 300 days Thus, higher transport costs RJ

  10. Scope of Case Study Estimation of higher transport costs due to re-routing of traffic from Mapoteng to Teyateyateng, using alternative, longer road of similar road carpeting characteristics Since there are no emergency bridges available to restore traffic over route B-24, and reconstruction of destroyed culvert would take 300 days, traffic is re-routed via alternative road Higher transport costs are to be estimated for that temporary solution, using traffic information and marginal cost of operation of vehicles that is available In addition, the potential benefits of having a stock of temporary bridges to enable prompt traffic re-opening are to be estimated RJ

  11. Assessment procedure • Estimate normal traffic costs in route B-24 • # of daily vehicles times their marginal costs of operation • Above times length of road B-24 • Multiply by 300 days 2. Estimate temporary costs of using alternative road sections • Reduce by 15% number of light vehicles • # of daily vehicles times marginal operation costs • Above times length of alternative road times 300 days 3. Higher transport costs = (2) minus (1) RJ

  12. Assessment procedure .. • Estimate costs of acquisition of set of 2 Bailey-type temporary bridges • Estimate cost of installation of above • Add up 1) and 2) • Estimate cost of traffic re-routing for 3 days only, which is installation time of temporary bridges • Add up 3) + 4) to obtain cost of temporary solution • Compare higher cost of transport estimated in first part of case study, which would be avoided, and divide by estimated cost of temporary solution (5) to obtain the benefit/cost ratio RJ
