QGis for georeferenced water modeling

QGIS is a free license software, that is, completely free and open source, it is a geographic information system that helps in the processing, analysis, projections, modeling, decision making and more of the data obtained from the territory and the elements that compose it. Geographic information systems (GIS) are a tool for working with different types of data, whether text, numerical, alphanumeric, photographs, etc. which have a geographical position. GIS or GIS helps identify problems, monitor changes, manage and respond to emergencies, make predictions, establish priorities, understand trends, generate maps, reports, graphs, etc. These systems are very useful, since the information obtained can be integrated, stored, edited, analyzed, shared, and finally, displayed geographically referenced in the interface of the software itself. In agriculture, it is capable of capturing NDVI, which in its acronym means normalized difference vegetation index, this being an important factor to estimate the quantity, quality and development of the crop. In addition, with it you can see a yield map in tons per hectare of the crop being grown. With QGIS you can develop calculation maps of the macroelements necessary for the proper development of crops and a water index depending on the NDVI that is observed, taking into account the equations that must be carried out to extrapolate the index and know the data in percentage. Also, the system allows for hydrological modeling of the basin, surface and groundwater flows, specific characteristics of the study area such as precipitation, runoff, water balances, groundwater levels, among others.
