Mr Oswald revealed extra details about some of the park's more thrilling rides this week, highlighting what will make the theme park a destination.
The 550-metre Bandit Bomber roller coaster will allow riders to release 10 litres of water on park visitors below at certain points along the ride. An on-board special effects laser system will put passengers in control of geysers and jets from their seats.
The Liwa Loop is the Middle East's first looping water slide. Similar to attractions at Wild Wadi, this thrill ride begins by dropping the visitor through a trapdoor and into a tunnel.
"Wild Wadi just did it, but they don't have a loop," Mr Oswald said.
On the Slither's Slides, riders can select six different themes on five slides for 30 distinct experiences. Each ends in a splash pool, where the park visitor will shoot out of a slide capped with a giant fanged snake head.
The park will also feature three main restaurants, a souq and merchandising and retail outlets.
The main attraction will be the Dawwama ride, a 20-metre high funnel that uses hydromagnetic power to propel six riders at a time uphill.
Stefan Zwanzger, a UAE-based theme park enthusiast who runs The Theme Park Guy website and has visited the Yas Waterworld site several times, said he is most looking forward to the funnel ride, which is called a Tornado.
"They've got one of the first Tornado slides in the Middle East, and these funnel-shaped slides are probably the best in the world," Mr Zwanzger said.
"There is nothing better than yelling at your family members or friends, or even strangers, from inside a Tornado. What the initial acceleration of a Formula Rossa coaster is for a theme park, the drop into a Tornado is for a water park – it is the peak of friendly terror."
