I can help you with that! Modifying the SWAT code to include vegetation growth in the tropics would require some knowledge of programming and the SWAT model structure.

Here are some general steps to consider:

Obtain the SWAT source code: You will need to obtain the source code for the SWAT model. The SWAT source code is written in Fortran, so you will need a Fortran compiler to modify the code.

Understand the SWAT model structure: Before you can modify the code, you need to understand how the SWAT model works. The SWAT model is composed of several different modules that simulate various hydrological and biogeochemical processes. You will need to identify which module(s) are responsible for simulating vegetation growth in the tropics and how they interact with other modules in the model.

Identify the variables and parameters relevant to vegetation growth: Once you understand the SWAT model structure, you will need to identify the variables and parameters that are relevant to simulating vegetation growth in the tropics. These may include things like temperature, precipitation, soil moisture, nutrient availability, and solar radiation.

Modify the code: Once you have identified the relevant variables and parameters, you can modify the code to include the necessary equations and algorithms to simulate vegetation growth in the tropics. This will likely involve modifying existing code in the vegetation growth module and possibly adding new code to the model.

Compile the modified code:

After making the necessary modifications, you will need to compile the modified code to create a new executable file that includes your changes.

It is important to note that modifying the SWAT code requires a good understanding of the model structure and programming in Fortran.

Additionally, any modifications to the code should be thoroughly tested to ensure that they produce accurate and reliable results.

Please Recommend my reply if you considered it useful .Thank you

Aahed Alhamamy Thank you so much for the information. I do not have good knowledge in Fortran but I understand the syntax of the language. I am wondering is there any available user guide or weblink that explains the procedures. Thanks again
