FUNDAMENTAL STUDY ON SPATIAL RESOLUTION OF TOPOGRAPHIC INFORMATION FOR RUNOFF ANALYSIS

Spatial resolution of topographic information gives a great influence to distributed runoff analysis. The objective of this study is to evaluate the effects of spatial resolution of DEM (Digital Elevation Model) on flood analysis with 1-D main flow channel. Kinematic wave propagation is simulated th...
