a) 60 m – Gutter

60 m - Gutter

Transparent side wall

Current-induced pronounced ripple bottom

Inlet: Transition from rectangular to circular profile

Outlet diverter with branch to return chute and weighing tank

Preformed dunes for initial sediment transport tests

b) 12 m – Gutter (practical gutter)

12 m - Gutter

Setting a changeover jump

Alternating jump on flat sole

Gutter in full length with view in flow direction

In this video you can see the alternating jump in flow direction:

The water height increases almost abruptly during the transition from shooting to flowing flow conditions. A wave-like impoundment appears. Wall effects can be observed along the channel wall.

c) 40 m – Gutter

40 m - Gutter

Research with a robotic fish

Horizontalrechen in trockener Rinne

Schematic representation of the 40 m - gutter

Modular horizontal rake system for mobile use in test troughs and model setups

d) 15 m – Gutter

e) 8 m – Gutter

8 m Gutter

Modified basin with installations of a slotted pass

Modified gutter outlet with needle weir

Symmetrically arranged inlet lines

Frame design to adjust the slope of the gutter

f) Deep Gutter (30 m – gutter)
