The DIN 19704 standard, titled "Hydraulic Steel Structures," is the primary German regulation for the design, calculation, and construction of movable and fixed hydraulic structures like lock gates, weirs, and dams. Standard Overview & Parts

For engineers in the hydropower and inland waterway sectors, DIN 19704 is considered the "gold standard" globally. It ensures that hydraulic structures can withstand extreme environmental forces for decades while maintaining operational safety.

The standard is divided into three main parts. Below are the most relevant links for viewing or reviewing the documentation: Part 1: Design and Calculation

  1. Find a preview: Go to Beuth Verlag and click "Vorschau" to see the table of contents and scope. This helps you decide if you truly need the standard.
  2. Use Eurocode EN 1993 (Eurocode 3): While DIN 19704 is the specialized standard for hydraulic steel structures, it often references the general steel design code (EN 1993‑1‑1 to -1‑9). You can obtain Eurocodes for free via the "National Annex" portals of some European countries (e.g., BSI, AFNOR, or DIN). However, this is not a replacement.
  3. Consult a public library: Major technical libraries (e.g., Technische Informationsbibliothek (TIB) in Hannover) have reading copies. You cannot take them home, but you can photocopy sections for research (under German copyright exceptions, § 60a UrhG).

DIN 19704 is a critical German technical standard (often used internationally) that ensures the safety and stability of steel structures in contact with water. It is divided into three main parts: Criteria for design and calculation. Design and manufacturing. Electrical equipment. How to Access the DIN 19704 PDF

The DIN 19704 standard, titled "Hydraulic steel structures," is the primary German technical regulation for the design, calculation, and construction of steel structures used in water engineering. It provides a comprehensive framework for engineering critical infrastructure like dam gates, canal locks, and intake trashracks to ensure they withstand the unique static and dynamic pressures of flowing water.
