Seepage of ponded water to equally spaced ditch drains is analyzed mathematically. Both cases with or without an impermeable barrier are considered. Solutions for cases with ditches at a finite distance apart are found by Successive conformal transformations. A few typical nomograms giving intensity of surface water intake and seepage rate are presented on the basis of recommended Solutions. The theoretical derivations are verified by the experimental data obtained on hydroelectrical analog models. In this paper...

Seepage of ponded water to equally spaced ditch drains is analyzed mathematically. Both cases with or without an impermeable barrier are considered. Solutions for cases with ditches at a finite distance apart are found by Successive conformal transformations. A few typical nomograms giving intensity of surface water intake and seepage rate are presented on the basis of recommended Solutions. The theoretical derivations are verified by the experimental data obtained on hydroelectrical analog models. In this paper piston-type displacement of salt into ditch drains is also studied. Formulas for the calculation of the positions of salt displacement fronts are developed. The displacement fronts calculated by analytical and flow net methods are compared with experimental data obtained on sand tank models. Their conformity is fairly well.

Based on electrolyte moldel, the authors of this paper tested three-dimentionalseepage flow movement for five types of conventional structures. The tests revealed the basicpattern and the law of changes in seepage flow field for pipe drainage. A qualitive describtion of drainage ability of five types of pipe structures is given in the paper. Meanwhile,flow coefficient values, which affect comprehensively pipe drainage performance, were used to make quantitative comparision and analysis for drainage performance of different pipe structures under different parameter conditions. Combined with previous testing results on sand tank,this paper provides basis of reasonable design for pipe structures. In addition,the analytic equations of two-dimensional seepage flow were developed by using conformal mapping methods,including scheme 4 that has only vertical crack and scheme 5 that permits water to flow through the whole pipe wall. Throug statistical and linear regression analysis for data, the approximate equations of three-dimensional seepage flow movement were also established.
