Statistical Analysis of Radar Rainfall Error Propagation
The prediction uncertainty of a hydrologic model is closely related to model formulation and the uncertainties in model parameters and inputs. Currently, the foremost challenges concern not only whether hydrologic model outputs match observations, but also whether or not model predictions are meaningful and useful in the contexts of land use and climate change. The latter is difficult to determ...
متن کاملNumerical simulations of radar rainfall error propagation
[1] The primary advantage of radar observations of precipitation compared with traditional rain gauge measurements is their high spatial and temporal resolution and large areal coverage. Unfortunately, radar data require vigorous quality control before being converted into precipitation products that can be used as input to hydrologic models. In this study we coupled a physically based atmosphe...
متن کاملEvaluation of Error Due to Applying Average Rating Curve as downstream Boundary Condition in Unsteady Flow Modeling
The rating curve is the relationship between the water stage and the associated discharge in a givensection of a channel. In steady flow, this relationship usually has exponential type, whereas inunsteady it flow has a looped shape. Since direct developing of actual looped rating curve by usinghydrometric methods is merely possible, steady-state rating curve is commonly used as a downstreamboun...
متن کاملuse of high-resolution x-band weather radar for areal rainfall estimation in small catchments
abstract obtaining reliable precipitation observations is important for hydrological simulations and weather forecasting. radar data can provide insight in the spatial variation of precipitation and can also detect large areas of rain and estimate rainfall rates. weather radar systems nearly always operate in s-, c- or x-band. since x-band systems require smaller antennas than those at c- or s-...
متن کاملSampling errors in rainfall measurements by weather radar
Radar rainfall data are affected by several types of error. Beside the error in the measurement of the rainfall reflectivity and its transformation into rainfall intensity, random errors can be generated by the temporal spacing of the radar scans. The aim of this work is to analize the sensitivity of the estimated rainfall maps to the radar sampling interval, i.e. the time interval between two ...
