Copyright ©2016-2019 FondUS Technology Co., Ltd. 2019 Delft3D - User Days2019 Delft3D - User Days Why We Want to Transfer SOBEK to Delft3D FM 2D model • High-resolution DEM data provide • 40m→20m→10m→5m→1m • Computing performance • SOBEK only use 1 core ( Base on CPU clock rate ) • Server CPU is more expensive than PC CPU • More Regions Data need to Provide • Parallel computing • Flexible Mesh Grid 9

So we run RR in SOBEK model first and get runoff value from it. Digital Elevation Model In Delft3D FM, DEM is defined in two parts, simulation Cell and Elevation. Boundary Condition In Delft3D FM there are two kind of boundary condition, water level in river and coast.
