Without substantially more water table and pieziometric data, as well as soil and geology substrate information, it may be best to draw water table direction estimates perpendicular to the topographic contours. The four measurement sites in or near the stream channel do not help with questions about water table depths on the mid to upper slopes. But the suggested available data is probably insufficient. One interesting author I remember is Toth in the 1960s I think. Some groundwater moves downward, and then laterally based on geology and other factors, and sometimes even moves upward due to potentiometric head differences. It’s complex.

You need to use GMS or groundwater vistas.

Dear Rajat Kumar Sharma

Given the complexity of the task, I would avoid the automated drawing and go for the manual flow drawing according to the good knowledge of the hydrogeological parameters.
