Storm Water Damage Risk Assessment Along The South Carolina Heritage Trail, Charles Pellett
Storm Water Damage Risk Assessment Along The South Carolina Heritage Trail, Charles Pellett
All Theses
This study was conducted to better predict and assess damage to high-value small-spatial scale landscapes from storm water. Storm water damage in the form of rill formation across the South Carolina Botanic Gardens (SCBG) Natural Heritage Garden Trail has been modelled as a function of contributing area using D8 and D-infinity flow direction algorithms on a preprocessed LiDAR-derived elevation raster. D8 and D-infinity algorithms were also applied over a set of stochastic Monte Carlo simulations (n=1,000) representing elevation error. The contributing area was calculated using each of the four methods for each 5'x5' cell along the trail. The output was …
