Sir, Ice Pressure against Dams
The American Society of Civil Engineers has recently reconstituted a research sub-committee to investigate the pressure exerted by ice against dams. The problem is an involved one, but of great economic importance in view of the allowances which have to be made in dam design for anticipated ice pressures. Very few actual observations of the pressures so exerted appear to have been made, but it is hoped to initiate a research programme of this character. Since the matter is not unrelated to glacial problems, it may be that some readers of this Journal can contribute information which will be of use to those responsible for this new investigation. If so, will they please communicate with me.
