PROJECT SUMMARY Over 100 years of deposited mine tailings prompted the Montana DEQ and U.S. EPA to embark on a major initiative to breach the Milltown Reservoir Dam and clean up contaminated sediments. But maintaining the flow of the Blackfoot and Clark Fork Rivers called for a potentially expensive diversion channel. Incorporating the AR-MORMAX® ARVS in the upper cross section to protect against the highest design flows minimized expensive gabion mattresses for use only in the low flow channel section. The result was over $1.1 million in savings, and a significant time and labor reduction.
ARMORMAX® FEATURES & BENEFITS:
High Performance TRM Channel Linin;
Superior hydraulic performance in an unvegetated condition
The Watershed Protection Department of the City of Austin is enthusiastic about cellular confinement technology. Though only recently added as a favorite system in their problem solving toolkit, this technology has been applied with dramatic success by in-house personnel in designing and building a 22 foot retaining wall to reinforce an eroding streambank. West Bouldin Creek makes a 90 degree turn at South Sixth Street in Austin which focuses erosive forces on the outside bank of the stream adjacent to the...
Water is a precious resource for the Carlota Copper Mine in Globe, AZ, and environmental regulations necessitated zero discharge from mine operations to the nearby Pinto Creek watershed. Construction of new heap leach pads in 2008 dictated the need for a diversion channel to maintain the flow of Powers Gulch without introduction of any leach effluent-Velocities associated with critical and supercritical flow required design of a series of drop structures capable of energy dissipation to control erosion. The use...
Woodland Hospital is one of Northamptonshire`s leading private hospitals located in Kettering. The hospital has 35 single rooms, all with en suite facilities, a multi bedded day ward and a two bedded high dependency unit.
When Ramsay Healthcare decided to increase the number of rooms and extend the facilities, one piece of equipment essential to the smooth running of the hospital required attention. The expansion of the hospital gave the consulting engineers FIRN the opportunity to review whether the existing...

In 2008, the City of Altanta faced a large problem: the single-lane road that provides the only entry point to its SWAT team training center was likely to be lost completely to erosion. Although the road had been lined with concrete barriers as a stop-gap measure, it was clear that more substantial action was required to save it.
Because the road is situated on a narrow tract of land between an in-remediation landfill and Intrenchment Creek, and across the street from a sewer treatment plant, Atlanta...
Floating islands have been constructed by the pipework engineering company CPV Ltd for bio-engineering and erosion consultants Water-Lines Solutions Ltd. The floating islands, using a buoyancy subframe, were recently installed as part of a new nature reserve, now being created at a former quarry and landfill in Rugby.Prefabricated at CPV’s Romsey production site, a total of 106 frames were used to construct three floating islands, with a total area of just under 1,000m2, for the nature reserve at Parkfield...
