Lines of Principal Curvature on Canal Surfaces in R^3 [PDF]
arXiv, 2006 In this paper are determined the principal curvatures and principal curvature lines on canal surfaces which are the envelopes of families of spheres with variable radius and centers moving along a closed regular curve in R^3. By means of a connection of the differential equations for these curvature lines and real Riccati equations, it is established ...

Open canals flow with fluvial to torrential phase transitions on networks [PDF]
arXiv, 2018 Network flows and specifically open canal flows can be modeled by systems of balance laws defined on topological graphs. The shallow water or Saint-Venant system of balance laws is one of the most used model and present two phases: fluvial or sub-critical and torrential or super critical.
