Calcolo informatizzato del bilancio idrico del suolo.

Computing water balance of soil. In this work a software was structured using Excel®2000 in order to automatically obtain the water balance diagram proposed by THORNTHWAITE and MATHER. The electronic spreadsheet just needs geographical, climatic and edafic data of the site analysed. This software can be either downloaded from http://www.comune.brescia.it web site or required at the email address: botanica@comune.brescia.it. Some modifications of the original procedure were carried out considering two new parameters, inclination and exposition of the site, as they directly affect the theoretical radiation. The last parameter was used to correct the formula of the heat index, originally obtained just on the basis of the latitude value of the site.
