dc.description.abstract	Subsurface emitters (SEs) are modeled as line sources with descending Darcian seepage impeded by either a natural impervious horizont or by designed and constructed barrier, which makes a wedge beneath SE. An analytical model assumes a tension-saturated steady-state 2D flow (Laplace's governing PDE) near an emitter, with a capping phreatic line, along which the stream function linearly depends on the horizontal coordinate that allows to use the Polubarinova-Kochina technique, {\it videlicet} a conformal mapping of a circular trigon in the hodograph domain on a reference half-plane. In the finite element model (HYDRUD2D, the Richards-Richardson PDE), a transient initial value problem (giving an asymptotic steady-state limit is solved in a fixed domain (an isosceles curvilinear tetragon or trapeziumIsobars, isohumes, streamlines,isotachs and the Christiansen uniformity coefficient are computed.	ru_RU
