HyCA®

How does HyCA work?

HyCA is founded on a database that can be fed with data from, among others, Excel, DINO, DAWACO and ASCII files. When data is added, the program automatically controls for double measurements, and inconsistent units are automatically converted into the standard setting that you have defined. HyCA is programmed in Matlab, but runs independently from it (no license needed).
Apart from the basic functionalities from Menyanthes, CHEMCAL and PHREEQC, the program contains a number of functions for the visualisation, control, analysis and modelling of hydrochemical data. HyCA recognises the parameters that you have defined, and automatically identifies exceedances of previously defined norms. A powerful GIS application makes it easier for you to screen and display your data on maps and in cross sections. Using a browser, you can very quickly and easily view, sort and select all information – including both the location data (depth, geological formation, X and Y coordinates) and chemical analyses.

Hydrochemical diagnosis

As a standard feature, all samples are controlled through subroutine CHEMCAL to determine among others the electrical conductivity, ionic balance, equilibria in the CO2-Ca-H2O system, base exchange, redox and pollution index, and chemical water type. PHREEQC, one of the best hydrogeochemical models available today, is fully integrated for in-depth interpretation of water quality aspects, like mineral-water equilibria and speciation of dissolved constituents. This can be done via either PHREEQC for Windows or PHREEQC Interactive. You can make use of all the functionalities of these programs via HyCA.

Visualisation

HyCA offers fast and user-friendly tools for the visualisation of water quality data. Standard options, like time series graphs, bar plots, Piper and Stiff diagrams, scatter plots, cumulative frequency distributions and box-whisker plots, require no more than a few mouse clicks. HyCA instantly creates maps – planar view, cross-section and three-dimensional – for each parameter and location(s) selected.
