“…4). This method is known as retromodelling and its accuracy has been successfully tested by Lang et al (2004), Naulet et al (2005) and Remo and Pinter (2007). We applied the retromodelling method separately for each of the seven studied floods along a 2700 m long reach of the Ondara River by the town of Tàrrega.…”

Abstract. Flash floods in the Ondara River have caused many fatalities and damages in the town of Tàrrega in the last 400 yr. Unfortunately, no flow records are available.However, floods can sometimes be reconstructed thanks to available historical information: limnimarks, written accounts and archaeological surveys. Indeed, from these data and using the retromodelling method on three different scenarios to take into account morphology changes, the peak flows of the seven greatest floods occurred in Tàrrega since the 17th century were estimated.The results showed that the heaviest flood's specific peak flow (10.7 m 3 s −1 km −2 ) ranks among the highest ever modelled or measured in similar-sized catchments in the Western Mediterranean region. The results pointed out, as well, that the changes in channel's morphology (mainly, the disappearance of a mediaeval bridge under sediment) caused by one of the floods increased the hydraulic capacity of a crucial crosssection. All this resulted in modest floods invading the town less often, but with much faster and, thus, more destructive flows.A preliminary estimation of the results' uncertainty was 4 % for great floods and 18 % for modest floods.The reconstructed peak flows will be introduced in a database for a future use in climatic and hydrological studies.

“…3) relative to historically connected floodplain area among major river reaches is: Levees prevent lateral animal migrations, disrupt important energy pathways, concentrate sediments, and increase moderate flood peaks and stage variation (Belt, 1975;Bellrose et al, 1983;Ward & Stanford, 1983;Bayley, 1991). Levees in southern river reaches have been shown to increase flood stages and restrict the Correlations are calculated between the nearest discharge gauge and upper, middle, and lower pool elevation gauges in each navigation reach (Theiling, 2000) flood zone (Belt, 1975;Chen & Simmons, 1986;Pinter et al, 2000;Remo & Pinter, 2007;Jemberie et al, 2008).…”

The Upper Mississippi River System (UMRS) is a large and diverse river system that changes character along its 1,200 mile network of rivers and canals and 2.6 million acres of floodplain. It supports more than 30 million people in its watershed, a significant commercial waterway, more than a million acres of ''floodplain'' agriculture and about one-half million acres of river-floodplain managed for fish, wildlife, and recreation. Large-scale geomorphology and climate patterns largely determine the hydrologic characteristics of a nested hierarchy of UMRS river reaches. The human impacts above are also important drivers determining hydrologic characteristics within the hierarchy. Understanding the relationship among physical and chemical processes and ecological responses is critical to implement an adaptive management framework for UMRS ecosystem sustainability. Historic or contemporary data from 42 locations were used to examine changes in UMRS hydrology and to demonstrate the utility of a multiple reference condition analysis for river restoration. A multivariate mathematical framework was used to show how river stage hydrology can be characterized by the variability, predictability, seasonality, and rate of change. Large-scale ''geomorphic reaches'' have distinct hydrologic characteristics and response to development throughout the UMRS region, but within navigation pool hydrology is similar among all impounded reaches regardless of geomorphic reach. Reaches with hydrologic characteristics similar to historic reference conditions should be examined to determine whether those characteristics support desired management objectives. Water levels can be managed, within limits to support navigation and agriculture, to more closely resemble natural hydrology for the benefit of a variety of species, habitats, and ecological processes.

“…less than 1 cm apart); and it was backwards because the peak flow was the unknown quantity, instead of being, as usual, an input of the model. Therefore, some authors call this method "retromodelling" (Remo and Pinter, 2007). The model applied was a unidimensional one in sub-critical permanent conditions (HEC-RAS v. 4.0;USACE, 2008).…”

Abstract. The Santa Tecla flash flood, a very heavy event occurred in western Catalonia (NE Spain) in 1874, was reconstructed with hydraulic and hydrological modelling tools in three basins. The hydrograph obtained in a first step and the basin soil moisture information ultimately allowed the estimation of the range of the rainstorm magnitude which caused the flash flood. The reconstruction of historical floods has proved useful to improve the flood probability analysis, especially in ungauged basins.
