                <dct:description xml:lang="en">This is the roughness coefficient information for the hydraulic model used by the Han River Flood Control Office for flood forecasting and other purposes. It provides data on the forecast basin name, application start/end dates, and cross-section name. The flood forecasting system uses the FLDWAV model as the hydraulic model. In the FLDWAV (Flood Wave) model, the roughness coefficient (Manning&amp;#39;s n) is a parameter that quantifies the energy loss (resistance) that occurs due to friction with the riverbed or walls when water flows. Since the FLDWAV model analyzes unsteady flow, such as dam failures or flash floods, this roughness coefficient is a critical factor that determines the accuracy of water level and flow calculations. It consists of flow rate and roughness coefficient.</dct:description>
