Its increase results in the addition of transport...

.... The chosen methods are Barton support graph, Laubscher's diagram, Potvin's stability graph and Jordá- Bordehore's graph. The results showed a good approach for preliminary studies. Barton's and Potvin's approach were considered conservative, when compared to the field expectation. However, Laubscher's...
