Executive Brief
River Flow
Clarity before a decision is made
The river flow modeling module is designed to simulate river flow, water quality, and sediment transport in estuaries, rivers, irrigation systems, canals, and other water networks.
The main basis of this module is the simulation of floods, advection–dispersion processes, water quality, and non-cohesive sediment transport using vertically integrated hydrodynamic equations. These include conservation equations, continuity equations, momentum equations, and the Saint-Venant equations.
Decision Supported
Define when and how to use river flow, including required data, configuration, validation, and scenarios.
Risk Controlled
Non-representative models, insufficient data, weak validation, and over-interpretation.
Success Criteria
Transparent, validated models that respond to scenarios at the decision scale.

Full technical basis and contextOpen this section to read the complete source technical narrative.
The river flow modeling module is designed to simulate river flow, water quality, and sediment transport in estuaries, rivers, irrigation systems, canals, and other water networks. This dynamic module provides detailed support for analysis, design, management, and operational planning in both simple and complex water systems. It is intended to improve the effectiveness of environmental engineering, water resources planning, water quality management, and decision-making.
The main basis of this module is the simulation of floods, advection–dispersion processes, water quality, and non-cohesive sediment transport using vertically integrated hydrodynamic equations. These include conservation equations, continuity equations, momentum equations, and the Saint-Venant equations. The main applications of this module include:
The data required to simulate the river flow module vary depending on the application. In general, the basic data include surface water processes, groundwater processes, rainfall inputs, hydrological characteristics, and spatial domain information. The outputs generated by the module also depend on the specific application being simulated. Various parameters can be produced according to the physical processes involved in the model.
The development and application of this module require expertise from multiple disciplines, including hydrology, hydrodynamics, hydro-oceanography, irrigation engineering, and applied water resources engineering.
