Simplify / densify stream network online with Hatari Utils - Tutorial
Hatari Labs Blog
by Saul Montoya
1M ago
Watershed delineation and stream network determination are common tasks on the hydrological analysis for any area of interest. There is a parameter on the stream network determination that allows us to have simple stream networks that resemble the main water courses or dense stream networks that map all the permanent / temporary streams. This is an applied example of  stream network determination on our online platform Hatari Utils where you can specify the number of upstream cells and interactively review the result.

Geospatial processing for a groundwater model in Model Muse in 14 minutes - Tutorial
Hatari Labs Blog
by Saul Montoya
1M ago
Groundwater model creation requires a complete set of spatial data for the different hydraulic parameters, boundary conditions and other model items. Vector and raster data need to be preprocessed, converted, reprojected to fit the requirements of Model Muse.  This tutorial covers an applied case of raster and vector data processing for a basin. The tutorial covers the steps to download and process the following data: Water network Basin extension Background satellite image Elevation Raster The tutorial also includes the following steps of building a hydrogeological model: De ..read more

Modeling Brine Density vs Concentration Regression Lines with Phreeqc and Aquifer App - Tutorial
Hatari Labs Blog
by Saul Montoya
1M ago
Complex geochemical simulations are entirely possible to be performed with Phreeqc coupled with Aquifer App and Python. Brines can be simulated at different concentrations to obtain relations that are input of other variable density flow models. In this case we have model one brine, sodium bicarbonate, with the REACTION keyword with moles values that range from 0.5 to 12 moles. Values of mass, volume, concentration, and density were processed in Python from the dataframes generated from Aquifer App. Tutorial Code Phreeqc input files: TITLE Brine 1: Dissolved sodium bicarbonate SOLUTION 2 ..read more

Simulation of water evaporation with Phreeqc and Aquifer App - Tutorial
Hatari Labs Blog
by Saul Montoya
1M ago
We define evaporation as the process of removing water from the chemical system in Phreeqc and this can be achieved with the REACTION keyword and a negative reaction coefficient. We have developed an applied case of water evaporation from precipitation water and the mix of the resulting water to restore the original volume. The whole Phreeqc setup, simulation and result analysis process has been in Aquifer App. Aquifer App link: aquifer.hatarilabs.com Tutorial Code Phreec file : TITLE Rain water evaporation SOLUTION 1 Precipitation from Central Oklahoma units mg/L ..read more
