✦ Synopsis

The ./)ee /mUm&O' qf the seepage .flow is a problem qfl close consideration in e,gim,ering. So fitr, an estimation of the wet set region usual]l' nee& a priori before tile numerical analysi.s, and the cot!figuration of the fi'ee houlMa O" is then obtained by successire aplwo.vhnation. The authors (2.[" this paper benefit .front a Ileal' nlathematieal expression:
