Draft:OpenHydroQual

From Wikipedia, the free encyclopedia

OpenHydroQual is an open-source, extensible modeling framework designed for simulating flow and reactive transport processes in natural and engineered water systems. Developed by Dr. Arash Massoudieh and collaborators, the platform facilitates the construction of customizable models for applications such as reservoir operations, rainfall-runoff processes, stormwater management, groundwater flow, and water quality in both surface and subsurface environments.[1]

Overview

[edit]

OpenHydroQual employs a component-based architecture where systems are represented as networks of interconnected blocks and links. Each block encapsulates balance equations for state variables like water storage, chemical concentrations, or energy, while links facilitate the transfer of these variables between blocks. The framework supports the inclusion of user-defined components and processes through plugins, enhancing its adaptability to a wide range of modeling applications.[2]

Features

[edit]
  • Modularity: Users can define custom components and processes using JSON files, allowing for tailored modeling of specific systems.
  • Chemical Modeling: Supports simulation of multiple chemical constituents and their interactions through user-defined reaction networks.
  • Optimization Tools: Includes parameters and objective functions to support model calibration and optimization.
  • Cross-Platform Compatibility: Available for Windows, Ubuntu, and macOS.[3]
  • Visualization: Offers graphical interfaces and output tools for model analysis.

Applications

[edit]

OpenHydroQual has been used in a variety of research and practical applications, including:

  • Modeling of activated sludge systems.
  • Simulation of bioretention systems for stormwater management.
  • Development of Streeter-Phelps models for stream water quality assessment.

Instructional videos are available demonstrating these applications:

Development and Availability

[edit]

The source code for OpenHydroQual is available on GitHub under the Apache 2.0 license, encouraging community collaboration and extension.[4] Extensive documentation, downloads, and instructional materials are maintained on the official website.
