Unformatted text preview: appropriatelytransformed crosssection (horizontal scale factor α = √ k v /k h ). How might the stability of the base be ensured? [University of London 2nd year BEng (Civil Engineering) examination, Queen Mary and Westfield College] Q3.10 Solution The flownet must be sketched on a transformed section, with the horizontal distances reduced by a transformation factor α = √ (k v /k h ) to account for the relatively higher horizontal permeability (see main text Section 3.14). = (k v /k h ) = (2.5 105 ÷ 104 ) = (0.25) = 0.5 The cross section is redrawn with the horizontal dimensions reduced by the transformation factor 0.5, and the flownet is sketched according to the rules and procedures set out in main text Sections 3.8 and 3.9, in Figure Q3.10....
