Finally, a complete alternative for the simulation of seawater intrusion on fully geospatial groundwater flow models of coastal aquifers based on open source software. The groundwater flow model was constructed on the Tupac Cloud platform with two stress periods and a total simulation time of 40 years.

The Tupac project is downloaded and run locally on Anaconda where the Buy package for variable density flow together with the transport model are implemented on a Flopy script. A graphical representation of the grid, boundary conditions and results from the flow and transport models are developed as well on the Jupyter notebook.

Applied case of regional groundwater modeling for a coastal aquifer with Modflow 6 using Voronoi meshes on Tupac Cloud. The aquifer has two stress periods (steady state and transient state) of 20 years each that simulate two phases of low/high aquifer exploitation. The model is constructed entirely from zipped shapefiles and rasters on the online platform. Results from the simulation are discussed on the water balances, water table distribution and cross section for all stress periods.

Tupac Cloud is based on Python and Flopy and every project can be downloaded to your machine for special analysis, furter Modflow 6 feature implementation, machine learning based calibration, or just because a local backup copy is required. This tutorial shows the complete procedure to download a Tupac Cloud project, the executable implementation, the scripts to run the flopy code and well as a description of the different files and folders from a model project.

This is an applied example of the impact trough time of a tunnel over the regional groundwater flow regime. The model has 5 stress periods with two variants of the drain (DRN) package implemented in Tupac Cloud. The tutorial covers all steps from model construction, boundary condition setup, model run and output data analysis.

Applied case for the evaluation of a drainage schema on a construction site with Tupac Cloud. The model has three stress periods where the drainage schema starts with well pumping for 10 days and trench drainage with pumping for another 10 days. Results from the water balance were analyzed as well as the final distribution of head on the proposed construction site.

Local scale modeling of a 4 stage trench excavation on a coastal aquifer. The main objective of this modeling work is assessing the impact of the excavation on the nearby groundwater flow regime. The modeling work was done entirely with the tools, charts and tables from Tupac Cloud.
