A major flood in 1974 eroded unweathered granite from an unlined spillway discharge channel which then resulted in the destruction of a penstock to the Burrinjuck Power Station.

Side channel spillways are typically used to discharge floods perpendicular to the general direction of flow by placing the control weir parallel to the upper portion of the discharge channel.

Each subsequent stroke usually re-uses the discharge channel taken by the previous one, but the channel may be offset from its previous position as wind displaces the hot channel.

The tunnel is part of a water diversion system consisting of a dam, a short approach channel, the first tunnel section, a short intermediary channel, the second tunnel section and a long discharge channel.

In 1991, the-long cooling water discharge channel from the power plant, which empties into the Potomac River, became the Dickerson Whitewater Course, a canoe and kayak training facility for the 1992 Olympic Games.

Because the electrostatic discharge of terrestrial lightning superheats the air to plasma temperatures along the length of the discharge channel in a short duration, acoustic echoing from terrain, and by the typically multiple-stroke characteristic of the lightning strike.

In order to avoid this, MMRCL would have to construct its own Storm water drains as well as Special Rainwater storage tanks similar to Tokyo s Metropolitan Area Outer Underground Discharge Channel facility to hold excess rain water during heavy rain-high tide situations.

When copper roofing, gutters, and rain leaders are electrically bonded to an earth termination facility, a pathway of low electrical impedance to ground is provided, however without dedicated conduction pathways to concentrate the discharge channel, a disperse energized surface may not be the most desirable.
