The Hydraulic Engineering Repository HENRY is the specialist repository for academic publications from the field of hydraulic engineering. It is a free service maintained and continuously developed by the German Federal Waterways Engineering and Research Institute (BAW).

All publications by the BAW, the Waterways and Shipping Administration of the German Federal Government (WSV) and their employees whose rights of use are held by the BAW or the WSV are archived in HENRY and made available online on a permanent basis and free of charge. Publications by scientific partner organisations are also made available via HENRY.

Academic publications relating to hydraulic engineering can be submitted, stored and published via HENRY by authors and publishing bodies free of charge. Both metadata and the publications themselves are made available permanently and for free based on the open access principle.

HENRY makes it easier to find publications from the field of hydraulic engineering as it is linked to other search engines and databases.
