1. Within the scope of the adopted model, the solution of the indicated optimization problems for triangular canals is unique. 2. The best angle of the side slopes in problems 1-3 is respectively equal to 38, 42, and 42.36°. 3. In a practically rather large interval of values of α the corresponding triangular canals are close in seepage losses to an optimal canal, and moreover the canals optimal in the sense of statements 1-3 are close in losses to each other. 4. On departing from the "fork" of optimal canals (for sufficiently large or small α) the corresponding canals differ in losses from optimal.
