MOHID-Land Preconfigured Hydrological Model for the Pedro do Rio Watershed: Ready-to-Run Simulations and Results

This dataset contains the MOHID-Land model developed for the Pedro do Rio watershed, located in the mountainous region of Petrópolis, Rio de Janeiro, Brazil. The model includes all necessary configuration files required to run the simulations and obtain results. It has been preconfigured to support scenarios S1 to S6, as described in the paper: "Enhancing River Flow Predictions in MOHID-Land Through Integration of Gridded Soil Data and Hydraulic Parameters Using the MOHID Soil Tool."

System Requirements and Execution Instructions

To run the simulations, the user must have Windows 10/11 (64-bit) and extract the contents of the provided ZIP file.

1. Navigate to the exe folder.
2. Double Click on the .bat file corresponding to the desired simulation. (the user can access the online log in the directory Log and the correspondent simulation)

It is important to note that each simulation is structured by year, and the user must execute the simulation for the previous year before running the next one.

Output Organization

• Simulation results are stored in the Results folder, organized by year and simulation scenario.
• Log files for each simulation are also available in the directory Logs.
• All data referenced in the paper correspond to the Node_Pedro do Rio, located in the Run1 folder within each year and simulation directory. The user can open this file useing Microsft Excel software or equal.

Soil Hydraulic Parameter Adjustments

Modifications to the PorousMedia.dat file, which contains the soil hydraulic coefficients, were derived using the MOHID Soil Tool (MST).

• MOHID Soil Tool repository: https://github.com/dhiegosales/MOHID-SOIL-TOOL
• The dataset used to generate the soil hydraulic coefficients is available at: https://doi.org/10.5281/zenodo.14913166

This dataset provides a ready-to-run hydrological model, enabling researchers to simulate and analyze river flow dynamics under different soil hydraulic conditions using MOHID-Land.
