Types of Effects :
1. Wall Descent - This is achieved where water flows softly from the spillway and cascades down the wall face into a pond or pool. Recommended to install a pump with a minimum flow rate of 50-60 litres per minute (l/m) per metre spillway width.
2. Falling Sheet - This is achieved where water flow is allowed to run away from the wall, so that a sheet of water "free falls" vertically downwards. Recommended to install a pump with a minimum flow rate of 120 litres per minute (l/m) per metre spillway width.
3. Projecting Sheet - This is achieved where a large volume of water passes through the spilllway, producing a solid sheet of water that projects away from the wall. Recommended to install a pump with a minimum flow rate of 150 litres per minute (lpm) per metre spillway width, and the spillway installed no higher than 900mm from water level. Note - The further the water drops, the narrower the water sheet widths become due to surface tension. The projection from the wall is approximately 100-200mm dependent on pump size.
