Paired hydraulically distinct vertical-slot fishways ... The objective of the present study was to compare the effectiveness of two hydraulically distinct vertical-slot fishways on an estuarine barrage in south eastern Australia to assess the complementary nature of these fishways as a holistic approach to providing passage for a fish assemblage at a low-level estuarine barrier. Field and numerical assessment of turning pool hydraulics ...

Two vertical slot fishways located in Duero River (North-Central Spain), subject to different hydraulic conditions, were studied for the validation of the proposed formulation.
The velocity profiles obtained in the field studies have confirmed the measurements made in the laboratory on scale models and have enhanced the general picture, particularly for the vertical slot fishways. This paper provides hydraulic engineers with information for understanding the primary hydraulic characteristics of fishways. Chapter 9 Fishways - Caltrans 9.2.3 Vertical Slot Instead of overflow weirs, flow in a vertical slot ladder is controlled by a narrow full depth opening between each pool (Figure 9.3). Width of the slot may vary, but is typically 1 to 1.25 feet. The advantage of vertical slots is that they can maintain favorable passage conditions over Effectiveness of a multi-slot vertical slot fishway versus a ... The present study compares the passage performance of the Iberian barbel, Luciobarbus bocagei (Steindachner, 1864), a potamodromous cyprinid, negotiating two different types of vertical slot fishways (VSF): a standard VSF and a multi-slot VSF (MSF). Results show that differences exist between configurations in the number of fish movements ...

Although a number of multispecies fishways now exist in North America, evaluations of these fishways are lacking. We used a passive integrated transponder antenna array to quantify passage success and passage duration of fish using a vertical slot fishway (85 m in length, 2.65 m elevation rise, 12 regular pools and 2 turning basins) at a low ...
Vertical slot fishways are increasingly common structures for the passage of a wide variety of migratory fish and contribute to the maintenance of fish diversity in fragmented rivers. These structures are designed with several geometric arrangements and, consequently, flow patterns through them can ... Field studies of fishways in Alberta - Canadian Journal of ... The velocity profiles obtained in the field studies have confirmed the measurements made in the laboratory on scale models and have enhanced the general picture, particularly for the vertical slot fishways. This paper provides hydraulic engineers with information for understanding the primary hydraulic characteristics of fishways. Chapter 9 Fishways - Caltrans
Can vertical slot fishways (VSF) operate with More recently Vertical slot fishways (VSF) Fish can swim through the slot at any desired depth. More efficient with changing water depth. Fishway with notches and bottom orifices at Nunes mini-hydroelectric power plant. VSF at Açude-Ponte Coimbra. Variation on the VSF. Influence of Hydraulic Factor of Vertical-Slot Fishway on… Vertical-slot fishway is widely used in different shape of fish-way due to the adaptability to water level amplitude, the hydraulic characteristics of the vertical-slot fish-way of different scale has been extensively researched by researcher domestic and overseas, the energy dissipation mechanism and... Sustainability | Free Full-Text | Conversion of Vertical… Deep slot fishways (DSF) are similar to vertical slot fishways (VSF) except that a sill has been placed at the base of the slot, and thus require a lower discharge to operate. The conversion of a VSF to a DSF, which requires minimal design modifications, can make for a more flexible design in inflow... ANADROMOUS SALMONID
