“…Using these ranges of uncertainty and assuming the water level uncertainties follow a normal distribution, the standard deviation can be approximated as (2 × range/4). Although 17 references contained data on water level uncertainties, several were cross referenced and only nine datasets as identified in Table 3 were considered to be reasonably independent (Linsley et al 1958, Ibbitt 1975, Ibbitt and Pearson 1987, Herschy 1995, Huard and Mailhot 2008, Scanlon et al 2008, Lang et al 2010, McMillan et al 2010, Ruiz-Bellet et al 2015. The nine standard deviations (in mm) of the uncertainty estimates are plotted in Supplementary Figure S1 (see Supplementary material).…”

The purpose of this paper is to determine uncertainty in the gauged range of the stage-gauged discharge relationship for 622 rating curves from 171 Australian Bureau of Meteorology Hydrologic Reference streamgauging Stations (HRS). Water agencies use many methods to establish rating curves. Here we adopt a consistent method across all stations and develop rating curves based on Chebyshev polynomials, and estimate uncertainties from standard regression errors in which residuals from the polynomials are adjusted to ensure they are homoscedastic and normally distributed. Uncertainty in input water level is also taken into account. The median uncertainties in mean response of the available gauged discharge relationship at median daily discharges for the HRS dataset range from +4.5 to −4.2% (95% confidence band) and for individual gaugings from +29 to −22% incorporating a water level uncertainty of ±4 mm. The uncertainties estimated are consistent with values estimated in Australia and elsewhere. ARTICLE HISTORY

“…Hence, numerical models are important tools for understanding flood events, flood hazard assessment and flood management planning. Previous studies showed the applicability of numerical models for producing hazard maps considering different flood management strategies [10,11] or reconstructing past flood events [12].…”

a b s t r a c tLlanos de Moxos are vast plains in the Bolivian Amazonia that are continually flooded by the Mamore river. The flood lasts for several days affecting important cities like Trinidad, drowning people, drowning cattle and swamping arable land. Because of the cloudy skies, remote sensing observations are limited to some areas and few days. Thus, there is huge uncertainty about characteristics of flood events and possible consequences. Two-dimensional (2D) numerical simulation proved to be an important tool for understanding flood events. The HEC-RAS model is one of the most popular hydraulic models. In 2014 a new version of HEC-RAS (HEC-RAS-v5) was released including 2D capabilities. The present study applied the new HEC-RAS-v5 to simulate the February 2014 flood event in the Bolivian Amazonia. The flood simulated shows good performance when compared with satellite image of the flood event. In addition, the simulation provides information like water depth, flow velocity and a temporal variation of the flood. Specific locations where water begins to overflow were identified. Over most of the flooded area the water velocity is lower than 0.25 m s −1 . During first ten days of the flood the flood extent increases rapidly. The flood depth allows identifying areas exposed to different hazard levels. The west plain of the Mamore river is the most exposed to the flood; it shows bigger flood extent, longer flood duration and deeper water depth. The flood that threatens the city of Trinidad originates in two locations; one located 32 km at the north and other located 10 km at the south west. The flood from the north gets close to Trinidad twelve days after it begins to overflow, while the flood from the south gets close to Trinidad seven days after it begins to overflow. Although the flood from the north is deeper than the flood from the south, the flood from the south begins flooded before the north. Thus, water borne and vector borne diseases may originate at the south earlier than the north. The city of San Javier gets covered by flood five days after the water begins to overflow. The study shows the applicability and the value of the 2D capabilities of the new HEC-RAS for flood studies.

“…On another hand, a set of studies focused on single flood cases seen as the largest historical floods and showed that these "extreme" floods mainly result from heavy precipitation accumulations (e.g. Blöschl et al, 2013;Ruiz-Bellet et al, 2015;Brönniman et al, 2018;Stucki et al, 2018).…”
