A lining system for a ditch or canal constructed with tight tolerances so a gasket is not required to connect liner channel sections. Each channel liner has a female slot on a first end and a male protrusion on a second end for adjoining channel liners. Flushing strips with male protrusions are installed in female slots in between channel beams. Flushing strips with variable Manning coefficients can be inserted based on a user's needs. Self-anchoring tabs can be inserted into anchoring slots on the outside of liner channels for anchoring the liner by soil compaction. Elbow sections can be used to change the direction of flow of the liquid. Elbow sections are adjoined to a liner channel similar to the adjoinment of in series channel liners to result in a desired angle for the change in direction.

1. A liner system comprising: a plurality of channel liners connected in series to a predetermined length, each channel liner comprising: multiple inverted channel beams and multiple channel slots in parallel with inverted channel beams;a female end comprising a joining slot that runs continuously from end to end, transverse to the longitudinal axis of the channel liner;a male end comprising a downward facing joining protrusion with a predetermined tolerance configured to fit tightly into the joining slot; andat least one variable height insertable flushing strip corresponding to a predetermined Manning effect, each variable height insertable flushing strip comprising a flushing strip protrusion configured to fit tightly into a channel slot. 2. The liner system of claim 1 wherein each channel liner comprises a trapezoidal cross-section. 3. The liner system of claim 1 wherein each inverted channel beam is concave. 4. The liner system of claim 1 wherein a bottom side of each channel liner comprises a structural honeycomb configuration. 5. The liner system of claim 1 wherein the joining protrusion comprises apertures, and the joining slots comprises threaded apertures and the joining protrusion and joining slots are compressed by joining bolts. 6. The liner system of claim 1 further comprising anchoring apertures and anchoring bolts for anchoring each channel liner to a structure. 7. The liner system of claim 1 further comprising at least two earth anchors for anchoring each liner. 8. The liner system of claim 1 further comprising self-anchoring tabs inserted into anchoring slots on an outside of each side section of each channel liner. 9. The liner system of claim 1 further comprising erosion control mats laid under a portion of each channel liner and away from each channel liner onto a top of a ditch bank opening. 10. The liner system of claim 1 further comprising elbow sections for changing directions of liquid flow. 11. The liner system of claim 10 wherein each elbow section comprises an angled portion in a center comprising angle Ø, at least two inverted elbow channel beams and multiple elbow channel slots in parallel with elbow inverted channel beams. 12. The liner system of claim 10 wherein each elbow section comprises a female end comprising an elbow joining slot that runs continuously from end to end, transverse to the longitudinal axis of the elbow section and an elbow male end comprising a downward facing elbow joining protrusion with a predetermined tolerance configured to fit tightly into the elbow joining slot. 13. A method for constructing a liner system for directing liquids, the method comprising the steps of: connecting in series a plurality of channel liners to a predetermined length, the step of connecting further comprises inserting a downward facing joining protrusion on a male end of each channel liner into a joining slot that runs continuously from end to end, transverse to the longitudinal axis of the each channel liner, wherein the joining protrusion and the joining slot comprise a predetermined tolerance configured to provide a water tight connection;diverting a liquid load and supporting loading capabilities from static or dynamic loads from fluids and debris, and other live loads or dead loads via multiple inverted channel beams on the each channel liner; andinserting at least one variable height flushing strip corresponding to a predetermined Manning effect, wherein the step of inserting comprises inserting a flushing strip protrusion on each variable height flushing strip into a channel slot on the each channel liner. 14. The method of claim 13 further comprising supporting a bottom portion of the each channel liner with a structural honeycomb configuration. 15. The method of claim 13 further comprising the step of compressing the joining protrusion and the joining slots. 16. The method of claim 13 further comprising the step of anchoring the each channel liner. 17. The method of claim 16 wherein the step of anchoring comprises inserting self-anchoring tabs inserted into anchoring slots on an outside of each side section of each channel liner and compacting soil onto the inserted tabs. 18. The method of claim 13 further comprising the step of controlling erosion via erosion control mats laid under a portion of the each channel liner and away from the each channel liner onto a top of a ditch bank opening. 19. The method of claim 13 further comprising the step of changing a direction of flow of the liquid by connecting a predetermined number of elbow sections, each elbow section comprising a turning angle Ø, together to a desired angle. 20. The method of claim 19 where in the step of connecting comprises inserting an elbow joining slot that runs continuously from end to end, transverse to the longitudinal axis of the elbow section into an elbow male end comprising a downward facing elbow joining protrusion with a predetermined tolerance configured to fit tightly into the elbow joining slot.
