“…The impoundment runoff index (that is the ratio between impounding capacity and annual runoff volume) is presently 57%. The Mequinenza reservoir (1966) is the largest one with a capacity of 1534 hm 3 , and together with the Riba-roja reservoir (1967, 210 hm 3 ), these have altered the flood regime in the Lower Ebro (López-Moreno et al, 2013): they have reduced by 30% the peak flows with a return period of between 2 and 10 years (Batalla et al, 2004); and by 25% the peak flows with a return period of between 10 and 25 years (Batalla and Vericat, 2011).…”

Reliable and complete knowledge of the historical floods is necessary for understanding the extreme hydrological dynamics of the rivers, their natural variability and anthropic changes. In this work we reconstruct the most important floods of the Ebro basin during the last 400 years in different areas of the basin. The analysis is based on four different areas: the Ebro River at Zaragoza, the Cinca River at Fraga, the Segre River at Lleida, and the Ebro River near its mouth at Tortosa. Based on a documentary research, we have first obtained relevant information about the initial conditions (rainfall duration and distribution, snow cover influence) and the maximum flood heights that allow to reconstruct the maximum peak flows by using hydraulic models and to calculate the subbasins contributions. The results show four main types of extreme floods: a) those affecting simultaneously all the subbasins with the highest peak discharges (Ebro at Tortosa in 1787: 0.15 m s km); b) those originated at the western basin, upstream from Zaragoza, with an Atlantic origin, presenting moderate maximum peak flows, caused by persistent winter rainfall and where snowmelt significantly contributes to the flood; c) those originating at the central Pyrenean subbasins, with Mediterranean origin, occurring, with high peak discharges. These mainly occur during autumn as a consequence of rainfalls of different duration (between 3 days and 1 month), and without significant snow thawing and d) finally, less frequent but very intense flash floods events centered in the Lower Ebro area with low peak flows. In terms of frequency, two different periods can be distinguished: from 1600 until 1850, the frequency of events is low; since 1850 the frequency of events is clearly higher, due to an increase of the climatic variability during last stages of the Little Ice Age. From the 1960's reservoirs construction modifies discharges regime.

Diel Cycle and Effects of Water Flow on Activity and Use of Depth by Common Carp

et al. 2015

Common Carp Cyprinus carpio is among the most popular and commercially important fishes globally. For this reason, it has been introduced worldwide and is invasive in many regions, with well-known ecosystems impacts. Like many other freshwater invaders it is thought not to tolerate strong flows well, but knowledge of the effects of flow on their activity, habitat use, and diel cycles are limited, despite this being crucial information for management and control. By means of ultrasonic telemetry we investigated depth use and activity of Common Carp in a small reservoir with a very low water residence time on the main stem of the Ebro River, the largest river by discharge in the Iberian Peninsula, over a 19-month period. The activity of carp and their use of depth displayed low seasonality compared with abiotic factors. However, carp exhibited diel vertical migration patterns, mostly in the warm season, shifting from deep positions near the reservoir bottom during the night (with decreased activity) to shallow waters during the day. This pattern included extensive use of hypoxic waters (<1.1 mg/L dissolved oxygen) and occurred largely at night. Activity and habitat use also varied among individuals and were significantly related to water flow; carp were less active and used shallower water during increased flows. The individual variability, the behavioral adaptation to refuge from high floods flows, and the extraordinary resistance to hypoxic waters might help explain why Common Carp is one of the most successful invasive freshwater fish speciesThis study was financially supported by the Spanish Ministry of the Environment and the Catalan Water Agency (MOBITROF project to J.
