On-Demand Webinar: Filter Design History and a One-Step Design Process
From ASDSO Dam Safety Toolbox
Association of State Dam Safety Officials, 2011
The webinar consists of two basic parts:
- A history of filter design practice including theoretical design considerations.
- A step-by-step design process with criterion for the design of a critical filter for one example soil type.
The primary topics covered in the first part of the webinar are:
- Early filter designs that addressed only interparticle seepage and piping.
- The historical research performed by Sherard et al to develop critical filters for soils with defects (cracks, etc.) in the soil.
- The basis for regrading soils that contain considerable coarse-grained particles (gravels).
The primary topics covered in the second part of the webinar are:
- A simplified, step-by-step process for designing filters that will comply with most agency design criteria.
- A step-by-step detailed example of a filter design for one of the four base soil categories.
The step-by-step process is related to the most common agency design criteria and steps, including those of the USACE, Reclamation, and the NRCS.
