WebThe standard approach is graphical. The elevation at B is between the elevations at A and C, so a contour passing through B (i.e., the 2700-ft contour) must cross the line segment AC. By the definition of strike, the direction of this contour is the strike of the unconformity surface. Thus the first step is to draw this contour (Fig. 2). WebYou can generate water level maps along with groundwater flow directions, as below: 1) Depth to water level map (bgl - below ground level) 2) Water Table map - water table contours for unconfined...
