This project called for the de-watering of a section of a creek Workers prepared the starting bank of the AquaDam.
Workers observe where the AquaDam will be installed. The berm the workers are standing on provided support for the AquaDam at the downstream side, which will be de-watered.
An excavator was used to clear the path for where the AquaDam will be installed.
Aggregate was added to the disturbed soil to make the bank more stable. The aggregate and soil combination produce a more stable bank for the AquaDam to make a seal too.
The aggregate was worked into the soil and smoothed over, to fill the void spaces between the stone with soil.
Workers also removed the rock from the creek bottom to help the AquaDam properly seal.
Rock picking is important to help with the seal the AquaDam makes with the creek bottom.
After the path for the AquaDam was cleared from the creek bottom, the AquaDam was installed. Note: the fill-tubes are elevated above the filled body of the AquaDam and tied off to its starting bank. A single closed end (SCE) AquaDam requires a bank to keep its starting point (open end) higher in elevation than the body of the AquaDam. The open end and fill-tubes of a SCE AquaDam must be elevated higher than the full height of dam along its given path. An AquaDam will only reach its full height at the lowest elevation along its given path.
his picture shows the de-watered side of the work area. This SCE AquaDam is in a line configuration, going from bank to bank. Fantastic job AquaDam!
