Hydrological variability not only affects the passage through fishways but also influences the permeability of obstacles. In this paper, we explore the possible impact of flat-V gauging stations to fish passage and migration. For this, radio-tracking and video monitoring observations were combined with computational fluid dynamics (CFD) models and sensor data in two flat-V weirs, using Iberian barbel (Luciobarbus bocagei) as target species. Results show that fish passage is conditioned by both hydraulic and behavioral processes, providing evidences about the hydrological scenarios where flat-V weirs may act as full or partial barriers to upstream movements. These findings are of interest to quantify flat-V weir impacts, for engineering applications and to establish managing or retrofitting actions when required.

This paper explores the use of hydraulic monitoring on fishways to detect the need for maintenance in stepped fishways. For this, a novel low-cost sensor network that encapsulates fishways hydraulics in a neural network is developed, generating the first autonomous obstruction/malfunction detection system for stepped fishways. The system is based on a network of custom-made ultrasonic water level nodes that transmit data and alarms remotely and in real-time. Its performance was assessed in a field study case as well as offline, considering the influence of the number of sensing nodes and obstruction dimensions. Results show that the proposed system can detect malfunctions and that allows monitoring of the hydraulic performance of the fishway. Consequently, it optimizes the timing of maintenance on fishways and, thus, has the potential of automatizing and reducing the cost of these operations as well as augmenting the service of these structures. Therefore, this novel tool is a step forward to achieve smart fishway management and to increase their operability.
