(2019) Hydraulics of vertical slot fishways: Non-uniform profiles

Juan Francisco Fuentes-Pérez, Jeffrey A. Tuhtan, Mario Eckert,Filipe Romão, Maria Teresa Ferreira, Maarja Kruusmaa, Paulo Branco
In Journal of Hydraulic Engineering
Vertical slot fishways are subject to variations in discharge of either hydrological or operational origin, which result in non-uniform water depth profiles. Although non-uniform conditions are present in most VSFs, they are rarely considered in the design and evaluation of fishways. The aim of this work is to provide an introductory analysis of how non-uniform water depth profiles affect the hydrodynamics within the pools of VSFs.

(2018) Spatial preferences of Iberian barbel in a vertical slot fishway under variable hydrodynamic scenarios

Juan Francisco Fuentes-Pérez, Mario Eckert, Jeffrey A. Tuhtan, Maria Teresa Ferreira, Maarja Kruusmaa, Paulo Branco
In Ecological Engineering
In this paper, we demonstrate the need to consider a wider range of fishway hydrodynamic scenarios for an integral assessment of fishways. To do this, the spatial distribution of Iberian barbel (Luciobarbus bocagei) in a full-scale model of a vertical slot fishway under three different hydrodynamic scenarios is investigated. Video tracking was used to analyze the fish’s spatial distribution, and an acoustic Doppler velocimeter and lateral line probe were applied to characterize the local hydrodynamic conditions of each scenario.

(2018) Differential pressure sensors for underwater speedometry in variable velocity and acceleration conditions

Juan Francisco Fuentes-Pérez, Christian Meurer, Jeffrey A. Tuhtan, Maarja Kruusma
In IEEE Journal of Oceanic Engineering
In this work we built a full-scale physical prototype of a differential pressure sensor speedometry system to be used in torpedo-shape underwater vehicle and we evaluated the performance in variable velocity (0 to 2 m/s) and acceleration (0 to 2 m²/s) conditions in a marine tow tank.We conclude that differential pressure sensor speedometry is a valid solution to perform underwater speedometry and we confirm that the system can provide instantaneous and stable velocity estimates with a sampling rate higher than 10 Hz.

(2018) 3D modelling of non-uniform and turbulent flow in vertical slot fishways

Juan Francisco Fuentes-Pérez, Ana T. silva, Jeffrey A. Tuhtan, Ana García-Vega, Ruth Carbonell-Baeza, Mark Musall, Maarja Kruusma
In Environmental Modelling and Software
In this study we highlight the necesity of considering non-uniform performance in the analysis of fishways. We demonstrate the benefits of 3D models to correctly characterize fishways, leveranging the synergy between 1D and 3D models. For this VOF method together with two turbulence modelling technics, RANS Standard k-ε and LES Smagorinsky models, are analyzed using OpenFOAM CFD platform.

(2017) Map-based localization in structured underwater environment using simulated hydrodynamic maps and an artificial lateral line

Juan Francisco Fuentes-Pérez, Naveed Muhammad, Jeffrey A. Tuhtan, Ruth Carbonell-Baeza, Mark Musall, Gert Toming, Maarja Kruusma
In IEEE International Conference on Robotics and Biomimetics (ROBIO)
In this paper, using recent advances and methodologies for bioinspired flow sensing, we propose a map-based localization technique that employs simulated hydrodynamic maps. The proposed conceptual idea could be an interesting complement to perform localization in those underwater environments with structural maps and a heterogeneous hydrodynamic, such as dams, harbour structures, fishways, caves, swers or any other drowned structure.

(2017) Villemonte's approach: A general method for modeling uniform and non-uniform performance in stepped fishways

Juan Francisco Fuentes-Pérez, Ana García-Vega, Fco. Javier Sanz-Ronda, Andrés Martínez de Azagra Paredes
In Knowledge and Management of Aquatic Ecosystems
This study aims to propose a general method for flow and water level calculation in stepped fishways considering the natural hydraulic variability of rivers. This will allow to assess fishways in nature-like scenarios and, therefore, contribute to the fulfillment of their main objective: allow free movement of fish fauna.

(2016) Underwater vehicle speedometry using differential pressure sensors: Preliminary results

Juan Francisco Fuentes-Pérez, Kaia Kalev, Jeffrey A. Tuhtan, Maarja Kruusmaa
In IEEE/OES Autonomous Underwater Vehicles (AUV)
This paper presents preliminary results of a differential pressure sensing system capable of providing instantaneous flow speed estimation for underwater vehicles. The system performance is analysed using computational fluid dynamics and flow tunnel tests from 0-0.5 m/s and angles of attack up to ±45º. The proposed speedometry uses inexpensive hardware, is geometrically simple, accurate and has low power consumption making it suitable for a wide spectrum of underwater vehicles.

(2016) Non-uniform hydraulic behavior of pool-weir fishways: A tool to optimize its design and performance

Juan Francisco Fuentes-Pérez, Fco. Javier Sanz-Ronda, Ana García-Vega, Andrés Martínez de Azagra Paredes
In Ecological Engineering
This study aims to model pool-type fishways with submerged notches and orifices under different water levels, and uniform and non-uniform performances. For this purpose, a real-scale fishway under 29 different hydraulic conditions is studied. The proposed new formulation together with a logical bottom-up iterative calculation can predict the observed water level distributions. The modeling under non-uniform profiles will allow to enhance and adapt fishways to achieve a greater fish passage during longer time periods.

(2015) Current velocity estimation using a lateral line probe

Juan Francisco Fuentes-Pérez, Jeffrey A. Tuhtan, Ruth Carbonell-Baeza, Mark Musall, Gert Toming and Maarja Kruusmaa
In Ecological Engineering
The lateral line probe (LLP) mimics the performance of flow sensing modalities present in many aquatic vertebrates. So far, the application of LLPs have been limited to idealized conditions, subject to rigorous calibration. In this paper, we present an algorithm that allows the use of LLPs for current velocity estimation without sensor calibration. The algorithm is calibrated using a closed flume and results were compared with the measurements of a laser Doppler anemometer in a vertical slot fishway.

(2015) Inventory and morphological characterization of high mountain lagoons and lakes in the provinces of Palencia and León (Spain)

Juan Francisco Fuentes-Pérez, Joaquín Navarro Hevia, Jorge Ruiz-Legazpi, Ana García-Vega
In Pirineos
High mountain lakes and lagoons are not a typical feature of the landscape of the Iberian Peninsula, but rather an exception in the natural environment, therefore its study and conservation presents great interest. This study arises to inventory and characterize a set of seventeen lagoon and their catchments located over the provinces of Palencia and León, without any kind of size restriction.

(2014) Modeling Water-Depth Distribution in Vertical-Slot Fishways under Uniform and Nonuniform Scenarios

Juan Francisco Fuentes-Pérez, Fco. Javier Sanz-Ronda, Ana García-Vega, Andrés Martínez de Azagra Paredes
In Journal of Hydraulic Engineering
Vertical slot fishways are a type of fish pass of wide operating range. This study aims to model the performance of these structures, under uniform and nonuniform water profiles, using discharge coefficients involving the downstream water level together with a logical algorithm. The proposed formulation together with the algorithm have resulted in a method that enables the improvement of the performance of both existing and future vertical slot fishways.
