It can, with some skill, be used to take rakk swarms, provided the swarm is grouped closely together, (the same can be said for bandits). It is best for fighting wide-body enemies, such as skags and particularly loaders, as aiming can start at the critical locations in the leg joints and the recoil can rise up to the other three critical locations on the upper torso. It is not good for fighting humanoid enemies due to their vertical frames and the horizontal spread of the shot. They also rely on knowledge of the ocean, the river and the riverbed to calculate the size and strength of tidal bores.Flee the Wave, Dude! – Fires 13 horizontal slow moving projectiles in a wave pattern that ricochets off of surfaces once if it does not hit an enemy.ĭue to the unusual nature of the pellet spread and behaviour, this gun is not much use past extreme close range. Navigators rely on sophisticated instruments, including geographic information system (GIS) technology. This threat to shipping is still a problem in areas with tidal bores. The wave would rush up the river, upsetting cargo ships and destroying docks. Before the French began managing the Seine, the unpredictable mascaret was responsible for the loss of hundreds of ships. Years of river management ( canals, dams, irrigation systems, dredging) eliminated the mascaret. A century ago, the Seine River in France had a strong tidal bore, called the mascaret. Human activity can change or even remove tidal bores.
Bears and eagles wade into the water hours after the wave passes to pick up fish along the banks. The Cook Inlet in Alaska experiences strong tidal bores. Crocodiles swim behind the Styx River bore in Queensland, Australia. In the Amazon, piranhas gobble up fish, crabs, and even birds left behind by the wave. For this reason, carnivores and scavengers are common sights behind tidal bores. Animals slammed by the leading edge of a tidal wave can be left dazed or dead in the silty water. Tidal bores have a direct impact on the ecology of the river mouth. Even watching a bore can be dangerous: Tidal waves have been known to sweep over lookout points and drag people to the churning river. state of Alaska have been pulled into the river, bay, or ocean. This makes the recreation sports of river surfing and kayaking very dangerous. Tidal bores can tear vegetation like trees from their roots. The bore often changes the color of the river from blue or green to brown as it whips up sediment. The tide behind the wave makes the river's water rise for hours after the bore passes.Ī tidal bore can be quite violent. The leading edge of the Qiantang River tidal bore can move as fast as 40 kilometers (25 miles) per hour. The roar of the tidal wave can be heard for hours before it bores up the river. Along the Qiantang River in Hangzhou, China, site of the world’s largest tidal bore, observers gather at tide-watching pavilions to observe the 9-meter (30-foot) wave. Neap tides happen during quarter moons, when tides are weakest.ĭespite some unpredictability, few observers are surprised by tidal bores.
Tidal bores almost never occur during neap tides.

Spring tides happen during new moons and full moons, when tides are strongest. Other tidal bores, like the pororoca, occur during spring tides. Tidal bores can occur every day, like the tidal bore of the Batang River in Malaysia, called the benak. A change in a river’s depth can be affected by rainfall or shipping traffic. The development of tidal bores depends on a number of factors, including wind and the depth of the river. Its sediment is emptied directly into the Atlantic and carried away by fast-moving currents. The tidal bore, called the pororoca, is so strong that the Amazon does not have a delta. A tidal bore develops here because the mouth of the river is shallow and dotted by many low-lying islands and sandbars. The mouth of the Amazon is not narrow, but the river still has a strong tidal bore. The Amazon River is the largest river in the world. When all of these conditions are met, a tidal bore is formed. The coast’s tidal range-the area between high tide and low tide-must be quite large, usually at least six meters (about 20 feet). However, the estuary, or place where the river meets the sea, must be wide and flat. In fact, there are few places where tidal bores occur. When a channel suddenly gets shallower, it experiences a negative surge. When a channel suddenly gets deeper, it experiences a positive surge. A tidal bore is a true tidal wave.Ī tidal bore is a surge. A tidal bore is a strong tide that pushes up the river, against the current. A tidal bore occurs along a coast where a river empties into an ocean or sea.
