4 Our Present: CRREL Mission Solve interdisciplinary, strategically important problems of the US Army Corps of Engineers, Army, Department of Defense, and the Nation by advancing and applying science and engineering to complex environments, materials, and processes in all seasons and climates, with unique core competencies related to the Earth s cold regions.

5 CRREL Ice Engineering History Ice Engineering Laboratory opened in 1979 Traditional Areas Ice control for hydroelectric production Ice problems and navigation Ice forces on structures Ice jam flood control Emerging Areas: Ice issues associated with: -Dam removal -Streambank stabilization and river restoration -Ice jam scour and remediation of contaminated sediment -Design of new navigation locks -Arctic oil exploration and development 5

6 Ice Engineering Ice Control for Hydroelectric Production Head losses due to ice: huge economic consequences Flow control, dredging, ice booms 6

7 Ice Problems for Navigation Ice Engineering Ice congestion of lock approaches and lock chambers River tows delayed by ice, tow size restricted Over half of US waterways ice affected River barges the most efficient way to move bulk products: CRREL R&D contributions include: -High flow bubblers to manage brash ice -Lock wall and dam gate deicing solutions -Innovative ice passage methods (from physical modeling) -Development of numerical models for ice passage at L&D CRREL BUILDING physical STRONG model study of ice passage at the Soo Locks 7

8 Ice Engineering Ice Forces on Structures / Vessels Recent CRREL physical model tests of shoreline protection system for Barrow, AK Daly et al. (2008) Estimation of Ice Impacts on Armor Stone Revetments at Barrow, Alaska Proceedings IAHR 19 th international Ice Symposium, Vancouver, BC, July 2008 CRREL tests of ice effects on riprap Sodhi et al NSF research ice breaker Nathaniel B. Palmer tested at CRREL Model tests and field validation of ice forces on submarine sail 8

9 Ice Engineering Ice Jam Flood Control Weir-with-piers ice control structure (ICS) in Quebec, 1970 s. Conceptual drawing of ICS with floodplain relief flow. In-channel relief flow concept developed for sites lacking floodplains to bypass flow around the ice accumulation such as Grasse River, NY, Montpelier, VT. Salmon River CT ICS, 2007 Cazenovia Creek, NY ICS, 2007 Hardwick, VT ICS,

11 Ice Processes and Dam Removal Ice Engineering Dam removal may have negative effects on river ice regime. Combination of historical research,numerical ice hydraulic modeling, field observation and engineering judgment used to predict the effect of dam removal on river ice processes. Milltown Dam, Clark Fork River, MT Israel River Weir, NH Edwards Dam, Kennebec River, ME Ft. Halifax Dam, Sebasticook River, ME Milltown Dam, Clark Fork River, MT Merrimack Village Dam, Souhegan River, NH Ballville Dam, Sandusky River, OH Israel River Weir, Lancaster, NH Veazie and Great Works Dams, Penobscot River, ME Great Works Dam, Penobscot River, ME 11
