1. A system for installing a curvilinear subsurface retention barrier comprising:
one or more barrier installation devices connectable to a forward moving device, wherein each of the one or more barrier installation devices has a three dimensional J-shaped film chamber comprising a film folding chamber with a curvilinear film entrance configured to fold an unfolded film to form a folded curvilinear film which is folded in a first direction, a folded film transfer chamber contiguous with the film folding chamber configured to receive and bend the folded curvilinear film in the first direction to form a bent and folded curvilinear film, and a film transfer and placement chamber configured to allow the bent and folded curvilinear film to unfold in a second direction to form a curvilinear film oriented for deposition into a curvilinear trough defining a concave cross section beneath a medium surface within a projected root zone; and one or more x, y, z positioning systems in communication with the forward moving device- and configured to position each of the subsurface retention barriers in a location which maximizes water retention in the projected root zone, wherein said x, y, z positioning systems include at least one physical positioning system connected to said barrier installation devices to control subsurface retention barrier depth (z) and at least one wireless positioning system to control a directional path (x, y) of the subsurface retention barrier. |
