We present a framework using publicly available LiDAR and orthophotography to locate and identify road crossings, i.e. the most prolific of barriers in forested landscapes, and evaluate fragmentation and passability at the landscape scale. Coupling the LiDAR stream network and private road network in the 3,223 km2 study area, we identified 1,052 stream crossings of which, 32% were culverts and 12% of the total stream network was potentially inaccessible due to these culverts. We correctly identified the type of stream-road crossings at >90% of any stream order and at 100% at Orders >2. The 10 culverts restricting the most stream kilometers, restricted >34% of the potential stream habitats for four species of fish, a result that provides the resource management with a first assessment for effective improvement of connectivity across this landscape. With this framework, managers equipped with appropriate imagery can create a stream crossing database with minimal funding, create an inventory of instream barriers, and prioritize removals at a landscape-scale, thus providing an effective assessment and decision-making tool for their habitat restoration efforts.","PeriodicalId":93201,"journal":{"name":"Journal of ecohydraulics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82882772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Capra","doi":"10.1080/24705357.2022.2042919","DOIUrl":"https://doi.org/10.1080/24705357.2022.2042919","url":null,"abstract":"Aquatic vegetation provides many ecosystem services with an estimated annual value of more than four trillion dollars (Costanza et al. 1997, Thomaz 2021). The services are strongly mediated by the interaction with hydraulics. Vegetation attenuates waves and current, protecting shorelines from erosion (e.g. Barbier et al. 2011; Arkema et al. 2017; Fonseca et al. 2019). Narayan et al. (2017) estimated that coastal marshes reduced flood damage due to Hurricane Sandy by $625 million. Further, the low energy environments created within vegetation provide nursery habitat for important fisheries (Costanza et al. 1997; Thomaz 2021) and promote the capture and retention of carbon carried in suspension, which contributes to the ability of aquatic vegetation to sequester larger amounts of carbon per hectare per year than rainforests (e.g. Fourqurean et al. 2012). Increasing hydrodynamic intensity can enhance nutrient uptake by individual plants (e.g. Lei and Nepf 2016; Gillis et al. 2017), but can also threaten vegetation survival (Katwijk et al. 2016). Because aquatic vegetation plays such an important role in protecting coastal environments and enhancing biodiversity, its protection and restoration have become a major focus in environmental management (Greiner et al. 2013; Sutton-Grier et al. 2015). On the other hand, excessive development of aquatic vegetation reduces channel discharge capacity, elevating flood risk. A better prediction of the hydrodynamic resistance generated by different species and areal distributions would enable managers to avoid this negative impact of vegetation. Management of vegetated landscapes, including restoration, depend on an understanding of the feedbacks between hydraulic conditions and vegetation growth and expansion (e.g. van Hulzen et al. 2007; Vandenbruwaene et al. 2011; Kondziolka and Nepf 2014). Similarly, the habitat selection and life-cycle behavior of aquatic invertebrates are closely linked to the organism-scale interaction with hydraulic conditions (e.g. Statzner et al. 1988; Smith et al. 2014; Lechner et al. 2016). Water depth, velocity, bed shear stress, and turbulence can influence habitat selection of macroinvertebrates and fish (e.g. Lamouroux et al. 1999; Dol edec et al. 2007); the swimming of fish larvae (Prada et al. 2018) and the migration of adult fish (Pavlov et al. 2008). Changes in land-use, installation of dams, and river regulation can all modify the hydraulic conditions, often having a negative impact on habitats and life-cycles. A better understanding of how hydraulics impact habitat and migration is needed to improve the restoration and management of freshwater fisheries and water resources.","PeriodicalId":93201,"journal":{"name":"Journal of ecohydraulics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84096658","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Abras de Mantequilla wetland (AdM) located at the centre of the Guayas River Basin (Western Ecuador), was declared a Ramsar site (2000) due to its important role in the conservation of bird fauna diversity. The wetland also supports significant populations of fish, including endemic species. The area exhibits two seasons: (i) a wet season (January–May); and (ii) a dry season (June–December). For the area of interest data is scarce, and a hydrodynamic model did not exist. In order to evaluate the interannual hydrodynamics and inundation patterns variability of this wetland system, a 2D hydrodynamic model was developed using the Delft3D software suite. Local knowledge was combined with field observations and expert elicitation to construct an appropriate model for the area. Results show that the Abras de Mantequilla is a river-wetland system that experiences extreme variations in hydrodynamic conditions from low water depths and almost stagnant conditions during the dry season, to a very dynamic behaviour during the rainy season. The inundation area ranges between 5 to 27 km2, water depths vary from 0.4 to 9 m and flow velocities from 0.0 up to 0.9 m/s. The “Nuevo River” is the main inflow to the wetland, with an overall contribution of about 85–90%, with peak discharges during February and March. A numerical tracer analysis indicated that the wetland can be divided into three main areas (upper, middle and low), with higher residence times found in the middle area. Overall, based on numerical hydrodynamic simulations it was possible to obtain adequate indications of the relative importance of the different river inflow conditions, as well as spatial and temporal inundation patterns, velocities and residence times under hydrological conditions varying from dry to extremely wet years. Furthermore, the hydrodynamic model provides a basis for other studies such as water quality assessment and primary production dynamics, as well as for determining the habitat suitability for fish.","PeriodicalId":93201,"journal":{"name":"Journal of ecohydraulics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86570982","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Particularly in Northern Ecuador, the runoff processes are less well-known due to the high variability of precipitation, young volcanic ash soil properties, soil moisture dynamics and other local factors. Previous studies have shown that the melting of glaciers contributes to runoff generation and that the páramo ecosystem plays an important role in regulating runoff during periods of low precipitation. Data collection and experimental investigations were carried out in a catchment of 15.2 km2 and altitude ranging between 4000 and 5700 m above sea level. Environmental tracers and hydrochemical catchment characterization were used for identifying runoff sources and their respective contributions during dry and wet conditions. Dry conditions are defined as periods where precipitation was absent for at least three consecutive days and wet conditions imply rainfall events. This study highlights the importance of the páramo on contributing to total runoff during baseflow (70% of total runoff) and the capacity of the páramo to dissipate the stream energy and buffer the peak flow during rainfall conditions. Electrical conductivity together with stable isotopes were identified as conservative tracers that characterize the end-member concentrations.","PeriodicalId":93201,"journal":{"name":"Journal of ecohydraulics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84632274","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Restoring river connectivity requires the construction of fish passage solutions, such as fishways for upstream and downstream migration. While many studies focussed on the upstream migration of diadromous fishes, and especially of adult Atlantic salmons (Salmo salar), we analyze juvenile behaviour under different hydraulic conditions at reservoir to improve the development of effective bypass systems for downstream passage of salmon smolt. Based on coupling three-dimensional (3D) computational fluid dynamics (CFD) simulations to smolt positions tracked by two-dimensional (2D) telemetry, the present study aimed to explore smolt behaviour in relation to hydraulic cues. More specifically, we explored how hydraulic conditions influence fish behaviour and how fish navigate depending on this behaviour. In 2017, 23 smolts were tracked in the reservoir of Poutès (Allier River, France), associated with different turbine discharge rates. 3D CFD simulations were performed and validated against field measurements in the reservoir upstream of the hydropower plant. The study of fish displacements in relation to flow conditions provided new insights with the use of thrust force, swimming orientation and direction as means to precisely characterize smolt behaviour, which can help in the design of downstream migration passage facilities. At Poutès dam, flow velocity, flow acceleration and turbulent kinetic energy are very low and therefore can lead to fish disorientation. However, results underlined that having a minimum flow velocity of 20 cm/s in reservoirs is sufficient to prevent delay and allow fish navigation.","PeriodicalId":93201,"journal":{"name":"Journal of ecohydraulics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72396536","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study was performed in a laboratory at the Bozeman Fish Technology Center (BFTC) in Bozeman, MT. Fifteen passage trials of different treatment combinations of approach depth and sill depth were performed in each ladder. A total of 310 grayling, in groups of 10 per trial, were allowed to volitionally attempt to swim upstream through each ladder. For the 1.83 m Denil, 81 of 137 participants successfully ascended resulting in an overall passage of 59.1% among all trials compared to 82 of 147 participants successfully ascending the longer structure for an overall passage of 55.8%. A quasi-binomial regression model was used to predict passage success for different combinations of approach and sill depths. Our study showed upstream passage success increased with deeper water depths at the sill for both ladders with the exception of the configuration with the shallowest approach depth and deepest water depth at the sill.","PeriodicalId":93201,"journal":{"name":"Journal of ecohydraulics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77732750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
