“…The Cazenovia Creek ICS has 12-ft gaps between vertical cylindrical piers that protrude 3 ft above the adjacent floodplain elevation. Based on model tests, it can retain ice at discharges approaching the 100-year flow, depending on ice thickness, although minor washouts of ice through the gaps begin to become significant at about half of this discharge (Lever et al 2001(Lever et al , 2003. At present, model tests are the most reliable way to quantify the ice-holding capacity of a given ICS design.…”

“…The ICSs designed for Hardwick, Vermont, and Cazenovia Creek, New York, are examples ( Fig. 1; Lever et al 1997Lever et al , 2001. As the name implies, these structures consist of boulders or concrete piers spaced across the main river channel to retain ice arriving from upstream.…”

“…The key is to ensure adequate flow relief to prevent over-topping of the piers or catastrophic ice washout through one or multiple gaps. Porous flow through the grounded toe can be sufficient to allow half or more of the total discharge to pass through the jam at peak flow (Lever et al 1997(Lever et al , 2001. Floodplain conveyance serves to bypass the remaining flow and limit stage rise, and hence forces, at the ICS.…”

The primary purpose of a breakup ice control structure (ICS) is to retain a breakup ice run upstream of a traditional ice jam problem area and thereby mitigate ice-jam flooding. By controlling ice-jam location, breakup ICSs also can prevent ice-related scour associated with dam removals or contaminated sediment remediation projects. This report briefly describes basic ICS types, purposes, and advantages and disadvantages, and provides engineering design guidance for their use. The use of numerical and physical models to design these structures is illustrated through case studies. The report includes a checklist to help designers compile the necessary input data and to conduct the analyses needed to ensure successful designs.

“…The percentage of the ice volume lost depends largely on the characteristics of the specific reach. Earlier estimates ranged from 20% to 80% (Lever et al 2000). Losses of 50% were used for this relatively small reach because the discharge is largely contained within the channel at breakup flows.…”

Evaluation of Dam Decommissioning in an Ice-Affected River: Case Study

Many dams across the United States are being decommissioned as a result of structural deficiencies or a desire to restore fish passage and to restore the natural stream. On northern rivers, dam removal affects the river ice processes and can result in increased ice jams and ice jam-related flooding. An analysis of the river system prior to dam removal is often necessary to ensure that increased ice jams, flooding, and damages do not result. This case study presents the types of analyses needed to investigate the ice impacts of the potential removal of the Merrimack Village Dam on the Souhegan River in Merrimack, New Hampshire. Of particular interest were the potential impacts to the historic Chamberlain Bridge. A HEC-RAS hydraulic model was used to estimate the ice jam thickness and resulting water surface profiles with and without an ice jam in place for both the pre-and post-dam-removal conditions. The results of this analysis indicate that removing the Merrimack Village Dam will not pose significant risk to the Chamberlain Bridge or to the area downstream.

Abstract:In the period 1999 to 2003, river ice has continued to have important socio-economic impacts in Canada and other Nordic countries. Concurrently, there have been many important advances in all areas of Canadian research into river ice engineering and hydrology. For example: (1) River ice processes were highlighted in two special journal issues There is the growing recognition, that these types of study require collaborative efforts. In our view, the main areas requiring further work are: (1) to interface geomorphological and habitat models with quantitative river ice hydrodynamic models; (2) to develop a manager's toolbox (database management, remote sensing, forecasting, intervention methodologies, etc.) to enable agencies to intervene better at the time of ice-jam-induced floods; and (3) finalize ice-jam prevention methods on the St Lawrence River to safeguard its $2 billion commercial navigation industry.
