Peak-operating hydropower plants are usually the energy grid’s backbone by providing flexible production. At same time, hydropeaking operations considered one of most adverse impacts on rivers, whereby aquatic organisms and their life-history stages can be affected in many ways. Therefore, we propose specific seasonal regulations to protect ecologically sensitive life cycle stages. By reviewing literature, establish a framework for hydrological mitigation based salmonid fish relationship...
As the share of renewable energy grows worldwide, flexible production from peak-operating hydropower and phenomenon hydropeaking have received increasing attention. In this study, we collected open research questions 220 experts in river science, practice, policy across globe using an online survey available six languages related to hydropeaking. We used a systematic method determining expert consensus (Delphi method) identify 100 high-priority following thematic fields: (a) hydrology, (b)...
ABSTRACT Both water managers and researchers have the same goal when it comes to fish conservation, namely, sustain, improve or restore aquatic habitat. To this aim, two‐dimensional (2D) hydrodynamic models been widely used in habitat studies because they simulate flow with high accuracy can predict dynamics. The River2D model is able integrate suitability curves for life stages simulated depth velocity fields riverbed characteristics of substrate cover, thereby estimating corresponding...
Abstract Endemic freshwater fish from the Mediterranean region are among most threatened species in world owing to increasing river degradation. Because of such threats, number restoration projects has greatly increased. However, they seldom planned with consideration species' life history, often resulting erroneous practices that compromise their success. This study assessed seasonal and size‐related microhabitat use by three endemic cyprinids (Iberian barbel, Lucio barbus bocagei ; Iberian...
ABSTRACT Fragmentation of freshwater systems is one the more common human‐induced impacts on environment, and most dramatic because it leads to disconnections among riverine habitats, severely affecting fish populations. To counter this form ecological abuse, there has been a significant increase number restoration actions. This work approached stream from holistic point view, combining habitat modelling with laboratory experimental research. A 2D hydrodynamic model was used test in weighted...
Abstract The rapid flow fluctuations experienced downstream of hydropeaking facilities can alter the river hydromorphology. Given dependence riverine fish on physical habitat, those alterations have potential to change physiology and behaviour fish. We assessed whether artificial velocity refuges mitigated physiological behavioural consequences for Iberian barbel ( Lucio barbus bocagei ). Hydropeaking trials were conducted in an indoor flume equipped with deflectors that created low areas...
In this study, different hydropower plant operation scenarios were proposed to assess the best habitat alternative for juvenile and adult brown trout (Salmo trutta). Habitat preferences determined based on field data collection translated into fuzzy sets rules both life-stages. The River2D model was applied a 100-m long stream segment immediately downstream of tailrace Ermida small (SHP) obtain 2D hydrodynamic description scenarios. modelling performed using Casimir Fish by combining flow...
Hydropeaking is the rapid change in water flow downstream of a hydropower plant, driven by changes daily electricity demand. These fluctuations may produce negative effects freshwater fish. To minimize these impacts, previous studies have proposed habitat enhancement structures as potential mitigation measures for salmonids. However, recommendation cyprinids remains scarce and their unknown. In this study, under simulated hydropeaking base-flow conditions are examined Iberian barbel...
ABSTRACT River ecosystems have witnessed a long history of human pressure, particularly the disruption freshwater fish populations. The awareness this situation has led to many habitat improvement projects, with variable degree success. In natural situations, populations co‐inhabit throughout hydrological cycle different degrees adequacy, and sequence favourable unfavourable conditions dictates abiotic constraints biotic interactions that shape final biological assemblages. We postulate part...
Abstract. Environmental flows remain biased toward the traditional biological group of fish species. Consequently, these ignore inter-annual flow variability that rules species with longer lifecycles and therefore disregard long-term perspective riverine ecosystem. We analyzed importance considering riparian requirements for efficiency environmental flows. For analysis, we modeled vegetation development a decade facing different in two case studies. Next, assessed corresponding habitat...
The rapid river flow variations due to hydropower production during peak demand periods, known as hydropeaking, causes several ecological impacts. In this study, we assessed the potential of an overhead cover and velocity-refuge structure in indoor flume indirect hydropeaking mitigation measure for cyprinid species Iberian barbel (Luciobarbus bocagei). We designed a lab-scale LUNKERS-type using two different materials which were used separately: Wood (opaque) acrylic (transparent), tested...
Hydropeaking, which refers to large and rapid flow fluctuations caused by the turning on or off of hydro-turbines generate electricity, is a topic growing interest due its impact fluvial ecosystems. To date, most hydropeaking studies have focused this hydropower operation mode invertebrate fish communities, but little attention has been paid riverine communities how functional traits may make plants resistant hydropeaking. We determined set 32 plant are expressed in 14 species, such...
