The applicability of the stage-fall-discharge (SFD) method in combination with acoustic Doppler velocity meter (ADVM) data, upstream a hydraulic structure, specifically, Sejong-weir located Geum River, Korea, was examined. We developed three rating curves: conventional simple curve data measured using an current profiler (ADCP) and floating objects, SFD ADCP ADVM. Because gate operation effect, every involved many uncertainties under 1000 m3/s (3.13 m2/s, specific discharge). In terms...
In general, the water stage-discharge relationship curve is established based on assumptions of linearity and homoscedasticity. However, between stage discharge affected from geomorphological factors, which violates basic curve. order to reduce error due violations, divided into several sections manager's judgement considering change cross-sectional shape. this research, objective-splitting criteria proposed measured data without subjective decision. First, it assumed that coefficient...
Abstract During extreme floods caused by climate change, reliable flow discharge data are essential for successful reservoir operation to mitigate downstream flood damage. Generally, the is computed using rating curve (RC) established from relationship between rate and water stage level. Determining parameters of curves subject uncertainties related difficulties limitations monitoring in covering a wide range variations. Especially at river confluences, pronounced when occur owing several...
This paper proposes an extended model evaluation method that considers not only the performance but also structure and parameter uncertainties in hydrologic modeling. A simple reservoir (SFM) distributed kinematic wave models (KWMSS1 KWMSS2 using topography from 250-m, 500-m, 1-km digital elevation models) were developed assessed by three evaluative criteria for performance, structural stability, identifiability. All provided acceptable terms of a global response, simpler SFM KWMSS1 could...
