“…Naghedifar et al (2019) proposed a basin/border irrigation model combining the 2D overland flow equations, based on the diffusion-wave approximation of the SWEs, with the 3D infiltration computed by the mixed form of Richards' equation using a non-orthogonal curvilinear coordinate system to speed-up the model computation performance. Liu et al (2021) developed a semi-Lagrangian solution of the 2D shallow water equations that was found to be, computationally, six times more efficient than the Eulerian scheme considered by the authors. Githui et al (2020) adapted the 2D ANUGA model, originally developed for inundation simulations, to simulate border and basin irrigation by incorporating an infiltration algorithm based on empirical formulations.…”
