Whitewater

Whitewater, usually spelled white water in both American and British English, is formed in a rapid, when a river's gradient increases enough to create so much turbulence that air is entrained into the water body, that is, it forms a bubbly or aerated and unstable current; the frothy water appears white. The term is also loosely used to refer to less turbulent, but still agitated, flows.

The term "whitewater" also has a broader meaning, applying to any river or creek itself that has a significant number of rapids. The term is also used as an adjective describing boating on such rivers, such as whitewater canoeing or whitewater kayaking.

Fast rivers

Four factors, separately or in combination, can create rapids: gradient, constriction, obstruction and flow rate. Gradient, constriction and obstruction are streambed topography factors and are relatively consistent. Flow rate is dependent upon both seasonal variation in precipitation and snowmelt and upon release rates of upstream dams.

White Water (pinball)

White Water is a 1993 pinball game designed by Dennis Nordman and released by Williams. The theme is based on White water rafting, which is reflected in the game's 'wild' ramps and very fast gameplay.

Overview

White Water is a non-licensed pinball machine with a primary objective of moving your raft down the river to "Wet Willy's" in order to get the "Vacation Jackpot." You move your raft down the river by shooting the flashing "Hazard" shots, each with a unique rafting theme name. Each time you complete a raft, the number of "Hazard" shots you must hit successfully to complete the next raft increases. It takes eight completed rafts to advance to "Wet Willy's." Successfully completing "Wet Willy's" enables the player to attempt the collection of the "Vacation Jackpot." There are subsequent objectives in the game, which include:
