A water cannon is a device that shoots a high-velocity stream of water. Typically, a water cannon can deliver a large volume of water, often over dozens of meters. They are used in firefighting, large vehicle washing, riot control, and mining. Most water cannons fall under the category of a fire monitor.

👉 Water cannon in the context of Riot control
Riot control is a form of public order policing used by law enforcement, military, paramilitary or security forces to control, disperse, or arrest people who are involved in a riot, demonstration or protest.
If a riot is spontaneous, then actions which cause people to stop and think (e.g. loud noises or issuing instructions in a calm tone) can be enough to stop it. However, these methods usually fail when there is severe anger, or the riot was planned or organized. Riot control personnel have long used less lethal weapons such as batons and whips to disperse crowds and detain rioters. Since the 1980s, riot control officers have also used tear gas, pepper spray, rubber bullets, stun grenades, and electric tasers. In some cases, riot squads may also use Long Range Acoustic Devices, water cannons, armoured fighting vehicles, aerial surveillance, police dogs or mounted police on horses. Persons performing riot control typically wear protective equipment such as riot helmets, face visors, body armor (vests, neck protectors, knee pads, etc.), gas masks and riot shields. Even though riot tactics are effective in controlling crowds, they can also lead to significant psychological effects on both the rioters and the police. Exposure to intense fear, stress, and violence during these confrontations can result in long-term mental health issues, like anxiety, post-traumatic stress disorder (PTSD), and heightened aggression, which can impact the well-being of protesters and police officers.

Water cannon in the context of Guns
A gun is a device that propels a projectile using pressure or explosive force. The projectiles are typically solid, but can also be pressurized liquid (e.g. in water guns or cannons), or gas (e.g. light-gas gun). Solid projectiles may be free-flying (as with bullets and artillery shells) or tethered (as with Tasers, spearguns and harpoon guns). A large-caliber gun is also called a cannon. Guns were designed as weapons for military use, and then found use in hunting. Now, there are guns, e.g., toy guns, water guns, paintball guns, etc., for many purposes.
The means of projectile propulsion vary according to designs, but are traditionally effected pneumatically by a high gas pressure contained within a barrel tube (gun barrel), produced either through the rapid exothermic combustion of propellants (as with firearms), or by mechanical compression (as with air guns). The high-pressure gas is introduced behind the projectile, pushing and accelerating it down the length of the tube, imparting sufficient launch velocity to sustain its further travel towards the target once the propelling gas ceases acting upon it after it exits the muzzle. Alternatively, new-concept linear motor weapons may employ an electromagnetic field to achieve acceleration, in which case the barrel may be substituted by guide rails (as in railguns) or wrapped with magnetic coils (as in coilguns).
Water cannon in the context of Operation Badr (1973)
Operation Badr (Arabic: عملية بدر ʻAmaliyat Badr), also known as Plan Badr (خطة بدر Khitat Badr), was an Egyptian military offensive and operation across the Suez Canal that destroyed the Bar-Lev Line, a chain of Israeli fortifications along the frontline of the Israeli-occupied Sinai Peninsula, on 6 October 1973. It was launched in conjunction with a Syrian military offensive against the Israeli-occupied Golan Heights, triggering the Yom Kippur War. During the War of Attrition, which preceded Operation Badr, both Egypt and Syria (previously constituents of the United Arab Republic) had been seeking to recover the territories that Israel had captured from them during the 1967 Arab–Israeli War.
The Egyptians had begun preparing for the offensive with training exercises in 1968, followed by operational planning from 1971 onward, including a deceptive operation. In the opening stages of the attack, known as "the crossing" (العبور al-'obour), Egyptian combat engineers utilized water cannons to rapidly clear numerous passages through the sand wall lining the eastern bank of the Suez Canal, simultaneously laying bridges and operating ferries that allowed armoured vehicles to cross into Israeli-controlled territory.
