Hydrolink is the quarterly IAHR members magazine. It publishes articles on projects, research, and new methods and tools of interest to the hydro-environment engineering community. Themed issues are suggested by an advisory board composed of ten IAHR members and articles are reviewed by the Hydrolink editor and the guest editor of each issue.

Hydrolink issue 2, 2020. Special issue on Hydraulic Transients

This issue of Hydrolink includes eight articles on different aspects of research and practice in hydraulic transients in urban and industrial systems. Hydraulic transients result from sudden changes in flow conditions in pipeline systems due to the planned or accidental closure/opening of valves or the starting/stopping of pumps or hydraulic turbines. These sudden changes can cause pressure waves through the system and pressure spikes generated by column separation and rejoining.

IAHR members can access the latest issue online.
