Of course you have to define the characteristics of the acquifer you want to carry out your work.

There are several free and open-source software (FOSS), Which can be utilized based on your specific requirement. Kindly go through the FOSS site:

Dear Mohammad,

Hydrological monitoring with in situ measurements presents many challenges for data management, particularly for large-scale catchments. Some of the links for the finest open source tools are given below with their applications.

Thank you for the response.

Hi Mohammad Alqadi ,

You might be interested as well in some tools related to time series analysis and stochastics:

1) https://www.itia.ntua.gr/en/software/

If you are interested in image-velocimetry for flow velocities and discharge in rivers, you can consider the following options:

1) KLT-IV: https://doi.org/10.5194/gmd-2020-187

2) FUDAA: https://riverhydraulics.inrae.fr/en/tools/measurement-software/fudaa-lspiv-2/

Finally, you can use the Geomorphic Flood Area (GFA) tool for the delineation of flood-prone areas in data-scarce environments:

All the best,

check it https://www.aquanty.com/hydrogeosphere/

There are a lot of free models out there, depending on your needs, as pointed out by many of your answers. Three examples of reputable sources I like include:

https://www.epa.gov/water-research/methods-models-tools-and-databases-water-research

Hope this helps.

Hi Mohammad

You can use SPAW (Soil Plant Air Water) which is especially design for the field scale hydrological modeling and water budgeting for the agricultural field. This model is free and developed by USDA. Very easy to use and simulate daily/monthly/yearly results. Please see link below for download software.

https://www.ars.usda.gov/research/software/download/?softwareid=492&modecode=80-42-05-10%20?

Let me know if you need help on it and any more question.

Thank you.

For rainfall-runoff modeling I would recommend HEC-HMS, SWAT, HBV-light

Hi,

Free software is available (HEC-HMS)

ARC GIS software you can use SWAT Model

http://edutechsoft.blogspot.com/

You can get a number of free softwares for hydrology and hydrogeological applications from the following site.

https://www.hec.usace.army.mil/software/

Yes USGS based softwares eg MODFLOW, Modelmuse, mt3dms, modpath. check their website for more info. All softwares are free and open source

Joan Nyika thanks for the answer .. i have already included them

Sajal Kumar Adhikary Thanks a lot

Various scintist as suggested above. I fully agree with them

Ajoy Kumar Saha, I am interested in the SPAW model. Could you please kindly give me more information on it?

Thanks.

ArcGIS and Swat combination is convenient for hydrological studies.

There are a number of hydrological models freely available. Also, you can see these articles to see different hydrological models used:
