“…Thus, expensive and inefficient fish ladders, which are usually built with more traditional hydraulic structures spanning river channels, are not required. Block ramp structures have been extensively investigated in recent years, both in the field and in hydraulic laboratories, as both physical and numerical models [20,[27][28][29][30][31][32]. Block ramps are environmentally friendly, low-head hydraulic structures that mimic natural river rapids, allowing fish and invertebrates to migrate [33] and, at the same time, are engineering structures that stabilize river and stream beds.…”

“…There are many operational and emerging methods for waterway gauging, varying widely in cost, accuracy, reliability, and risk (Tauro et al, 2018;Gordon, 1989;Costa et al, 2000;Tauro et al, 2016;Yang et al, 2020). Intrusive methods range from the resource intensive installation of hydraulic control structures to measure discharge rates analytically using simpler water level measurements within a designed range by obstructing and controlling the flow through a standardised geometry (Boiten, 2002) (often to the detriment of aquatic species (Mueller et al, 2011), as well as sedimentation and erosion (Pagliara and Palermo, 2015;Ogden et al, 2011)), through to the risking of people and equipment entering the stream to measure velocities using passive mechanical current meters or active acoustic doppler velocimetry profiles (Gordon, 1989).…”
