Iber v3. Reference manual and GUI. 1D shallow flows calculation module

Abstract

Iber is a two-dimensional hydraulic model for the simulation of free surface flow in rivers and estuaries, and the simulation of environmental processes in fluvial hydraulics. Since the release of the first version of Iber, which included a hydrodynamic calculation engine fully coupled with sediment transport processes and turbulence, it has evolved to become a free surface flow modelling tool for highly complex environmental processes. This document presents the developments made for version 3, specifically, for the new calculation module for the simulation of one-dimensional shallow flows called Iber-1D. The nature of this module enhances the current capabilities of the urban drainage model (Iber-UD) and homogenises the code both sewer and channel networks, but also includes particular capabilities for simulating irrigation channels (e.g., operation tools). Additionally, a calculation module for one-dimensional suspended sediment transport has been developed, being fully coupled with the hydrodynamics. The graphical user interface (GUI) has been adapted to the module's new features to achieve a simple and user-friendly workflow.
