Designed by the Hydrogeology Group - Department of Geotechnical Engineering of the UPC. ETP calculation and calculation of balances of water in the soil

EasyBal is designed to evaluate water balance per unit of soil area as a function of precipitation, the potential evapotranspiration (or ETP), temperature and irrigation. Outputs are the deficit and the recharge of the aquifer. Some extras have been also included in the new EasyBal version. On the one hand, the user can select the program language, English or Spanish. On the other hand, the ETP can be introduced as input data or can be automatically calculated (using the Hargreaves and Thornthwaite methods) and graphically compared with the input data, allowing the user to select the best option in the menu or graph. Moreover, depending on the original data (daily or monthly), the program allows us to use all or just some options. All the output is presented in three tables and plotted in two graphs (rain vs. recharge). No data treatment is needed for the input or for the output. In this case, it is not necessary to export results to other software.

EasyQuim (EasyQuim, 2013) program is designed to to improve the sorting, analysis, calculations, visualizations, and interpretations of hydrochemical data. It computes some calculations such as unit conversion, balance errors or ionical relationships. It also plots Piper, Schöeller-Berkaloff, SAR (Salinity) and Stiff diagrams. The new version should provide three main advantages. The first advantage involves increasing the number of samples (up to 200), the second entails adding a “Sample Selector” and the third advantage involves the possibility of a space-time analysis. The “Sample Selector” provides a powerful tool to use the updated EasyQuim as a Database and to plot different sample combinations, whereas the connection to the GIS-based software QUIMET will allow analyses in the spatial and temporal dimensions.
