Seepage in dams

Seepage in dams

Seepage in dams

Hello everyone,
I am an IBDP Physics teacher . I need a source of data for academic purpose for writing a detailed essay on seepage in dams.It should be at high school level (12th).
On what factors seepage in dams depends and how can it be minimized.
Any information in this regards will be highly appreciated.
Thank you.

RE: Seepage in dams

note that this is not at 12th grade level, you will find that seepage in dams is definitely a PhD level subject

RE: Seepage in dams

I think you can simplify/focus the quite involved topic to two mean factors - hydraulic head differential, and permeability characteristics of the soil beneath the dam. You can even consider increase student's interests by making a prototype in a fish tank, and add dye to demonstrate the seepage flow.

RE: Seepage in dams

Some pictures.

RE: Seepage in dams

Vertical clay soil wall of very low permeability is often added to the interior of normal soil and concrete dam structures to prevent through-the-wall seepage when dams are founded on impermeable soils and/or bed rock below. Permeability of normal concrete can be relatively high in itself.

RE: Seepage in dams

Minimizing seepage in dams seems like a highly specialized topic to present to high school students. They would probably benefit more by teaching them basic principles.


RE: Seepage in dams

The concept is simple - block the flow passage by impervious core (usually clay core in earth dam), and lengthen the flow channel using seepage cutoff walls. Other important features should be brought to teaching are "piping" under dam, erosion at downstream toe, and preventive measures.

RE: Seepage in dams

seepage control is not always just blocking the flow, perhaps more important to filter it. so filter diaphragms are maybe just as important

RE: Seepage in dams


Look into the design of earth dams will help. It forces the flow to the other direction/location instead of passing right through the dam that would resulting in instability. Diversion channel is a good path for diverting the flow to relief the pressure.

RE: Seepage in dams


Thanks. I agree this is a good way to do it.

RE: Seepage in dams

Thanks again. This was the way we design.

White Paper - Addressing Tooling and Casting Requirements at the Design Stage
Several of the tooling and casting requirements of a part can be addressed at the design stage. If these requirements are not addressed at the design stage, lot of time is spent in design iteration when the design reaches the die caster. These design issues lead to increase in time and cost of production leading to delay in time to market and reduced profits for the organization. Download Now
White Paper - The Other Side of Design for Assembly
Assembly level constraints need to be satisfied before the design can move downstream. This white paper will go through the various assembly level issues, which need to be tackled by various organizations on a regular basis. Know more about DFMPro, a design for assembly software. Download Now
