Bill – the Source article is a good read – and nice to see diverse opinions on the issue of Global Sea Level Rise (SLR) – and its regional outlay in terms of relative sea level rise (RSLR), in particular on sinking or subsiding coasts. You and I and other learned colleagues interacted ...

ASCE's Source has an article about relative sea level rise issues along much of our coastlines and what engineers ae doing in response. LINK What is being done in your region to adapt to relative sea level rise? Bill Mc ------------------------------ William McAnally Ph.D., P.E., BC.CE, BC.NE, ...

U.K.'s "CIRIA C816: Buried pressure pipelines: designing for thrust restraint" is a very good and authoritative "standard" for thrust bock requirements and design. You may want to consult it. ------------------------------ Monayem Akhand Ph.D., P.E. (Texas), M.ASCE Civil/Structural Engineer Portsmouth ...

Anchor blocks are not required for a straight, flat, fully butt-fusion welded, buried HDPE DN800 water pipeline. Because butt-fusion joints transfer tensile loads continuously along the pipe, a fully welded HDPE pipeline behaves as a single monolithic structure. When buried at a depth of 3 meters, the ...

What is the purpose of anchor block in HDPE piping? Ans: When a moving mass of water (or any lump of material in that matter) moves in a certain direction (must be a straight line; as a vector), by virtue of having velocity (a vector) the mass will possess momentum (quantified as m*v or mass times ...

In addition to the points raised by Bill and Dilip, it should be noted that any submerged object possessing volume-such as a pipeline-is inherently subject to buoyancy forces. In the absence of adequate ballast or anchor blocks, the pipeline would be prone to uplift and potential flotation. Furthermore, ...
