Updated Piping Toolbox Now Available

We are pleased to announce that the updated version of the Piping Toolbox has been finalised, incorporating valuable feedback and comments from colleagues in the field.

The update includes numerous editorial changes, corrections, and clarifications. Key updates are:

  • New Section (7.6.3): Guidance on estimating hydraulic shear stresses in vertical cracks where the flow is controlled by a filter or transition at the downstream end of the crack.
  • Enhanced Section (7.5.2): Expanded content emphasizing the importance of considering the swelling of crack sides.
  • Revised Probabilities (Section 9.4.2): Adjusted probabilities for the progression of backward erosion piping in Table 9.3.

We sincerely thank everyone who provided feedback on the draft, which has greatly improved the quality and clarity of this resource. Individual responses to submitted comments will be forwarded shortly.
