| Description: | Technical report A 1:25 scale model was constructed to study structural improvements to the Wailupe Stream drainage basin. This drainage basin is located approximately eight miles southeast of Honolulu, HI. Structural features that were evaluated include the concrete lining of the stream and modification of the Kalanianaole Highway Bridge (KHB). Concrete lining near the KHB and KHB modification was designed to allow stream flow to pass under the existing bridge without overtopping. This required raising the upstream channel walls (flood walls) and adding a parapet wall on the upstream side of the bridge. During large flow events, the channel beneath the bridge will act as a conduit with pressurized flow passing beneath the bridge deck. Measured piezometric pressures and current velocities will be used to determine hydraulic loadings for design of a bridge deck restraint system. |
