A theoretical, approximate solution is presented for steady rainfall or steady irrigation water seeping into ditch and tile drains in soil when the rainfall water is reinforced by the simultaneous upward seepage of artesian water. In the approximation it is assumed that the head loss in the narrow portion of the flow region above the lowest point of the water table arch is negligible. Utilizing a derived potential function and stream function, flow nets are presented for different rainfall and artesian flow conditions and for the drains running full and half full. A table of numerical values is presented for computing maximum water table heights. The theory is for an artesian basin at finite depth; for infinite depth, others have solved the problem for heights of water tables but not for flow nets. (Key words: Drainage; groundwater; artesian flow; irrigation) [ABSTRACT FROM AUTHOR] |
