Types and costs of adjustable river waves

A variety of adjustable river waves designs make good and consistent waves. Projects costs range from $100,000 creative commons designs to $3,500,000 patented wave systems. Low-cost wave designs can make excellent waves. This article provides simple diagrams and costs for wave types. All diagrams are based on published information in news articles, project pictures, or site visits.

Summary of wave costs

All of these wave designs make good waves. All costs are for completed projects except the multi adjustable kicker system which is in engineering.

Wave type	# of waves reviewed	Costs
Kicker at end of ramp	5	80.000 € to 100.000 €
Suspended ramps	3	1.400.000 € to 2.400.000 €
Adjustable ramps without kickers	2	$1,000,000+ Hard to tell because part of larger projects.
Multi adjustable kicker system	1	$300,000 Costs TBD still in engineering.

Kicker at the end of a ramp

The kicker at the end of a ramp wave type is a public domain design that consistently makes good perpendicular waves for low cost. More complex versions that adjust ramp angles as well as kicker angle may have patents.

Wave	Width	Cost of completed projects	Year built	Wave design
Almwelle, Austria	5m	Low. 90,000 EUR	2010	Graz Building Waves
Bend, USA	11m	Medium. Small part of a large $9.7M whitewater and natural park.	2016	Surf Anywhere and River Restoration
Don-Surf, Russia	7m	Low.	2020	Don-Surf
AnnecyWave, France	8m	Low. 90,000 EUR.	2021	Surfeurs d’eau Douce and Hydrostadium
Blackforest Wave, Germany	4.5m	Low. 80,000 EUR.	2021	Blackforest Wave e.V.

Example waves that use variations of a kicker at the end of a ramp

Simple diagram of kicker at end of a ramp

1. Headwater gate controls the drop size.
2. Fixed ramp accelrates the water for the wave.
3. Kicker shapes the wave angle.
4. Not needed.
5. Not needed.
6. Tailwater gate controls tailwater elevation.

Suspended ramps

These wave systems produce excellent waves, are patented, and they are very expensive. The suspended ramp systems involved precisely lifting and controlling large steel structures weighing over 10 tonnes.

Wave	Width	Cost of completed projects	Year built	Licensor
The.RiverWave, Austria	10m	High. Around 2,000,000 EUR.	2019	Patented by The.RiverWave
Nuernberg Dauerwelle, Germany	8m	High. 2,400,000 EUR.	2022	Patented by DreamWave
Wolfratshausen wave, German	8m	High. 1,400,000 EUR.	On hold	Patented by DreamWave

The.RiverWave

Simple diagram of The.RiverWave

Diagrams are not to scale. The ramp is lifted at both the upstream and downstream ends. Tailwater is managed by raising and the lowering the ramp. Wave can be made to disappear as needed.

1. Upstream part of ramp sets the height of the drop.
2. Ramp accelerates the water and helps set wave steepness. Ramp can be fully lowered.
3. Kicker angle shapes the wave steepness
4. Trash gate prevents large material and people from going under the ramp.

Nuernberg-Dauerwelle

Diagrams are not to scale. The ramp is rotated to lift upstream end. Downstream end may be liftable. Tailwater is managed by raising and the lowering the ramp. Wave can be made to disappear as needed.

1. Upstream part of ramp sets the height of the drop.
2. Ramp accelerates the water and helps set wave steepness. Ramp can be fully lowered.
3. Kicker angle shapes the wave steepness

Adjustable ramps without kickers

These wave systems produce good waves, are patented, and have a medium to high cost.

Wave	Width	Cost of completed projects	Year built	License
Boise Phase 1 – Waveshaper 2, USA	6.5m or 10m	Medium to high. Part of a $3M+ whitewater park.	2012	Patented by McLaughlin Whitewater Design Group.
Boise Phase 1 – Waveshaper 3, USA	8m	Medium to high. Part of a $3M+ whitewater park.	2012	Patented by McLaughlin Whitewater Design Group.

Boise Phase 1 – Waveshaper 2

Simple diagram of Waveshaper 2

Diagrams are not to scale.

1. Headwater gate sets the drop height.
2. Ramp accelerates the water and sets wave shape.
3. No kicker.
4. Trash gate prevents objects and people from going under the ramp.

Boise Waveshaper 3

Simple diagram of Waveshaper 3

Diagrams are not to scale.

1. Pneumatic bladder inflates or deflates to raise of lower the ramp. The upstream end of the ramp sets the drop height.
2. The ramp angle sets the wave shape. The downstream end of the ramp is raised or lowered using hydraulics.
3. No kicker.
4. Trash gate prevents objects and people from going under the ramp.

Multi adjustable kicker system

Surf Anywhere created the innovative multi adjustable kicker system to provide high quality rivers waves at low cost that encourage more wave development. This system makes the widest variety of river waves of any wave system including lefts, rights, bowls, perpendicular, and more.
