aplicatiilor la scara baz<strong>in</strong>ului hidrografic <strong>pentru</strong> care este imposibil de stiut parametrii hidraulici <strong>pentru</strong><br />
fiecare celula si de aplicat scheme numerice pe baza solutiei ecuatiei lui Richard.<br />
Rezultatele au demonstrat ca varianta propusa este capabila sa descrie adecvat evolutia cont<strong>in</strong>utului<br />
de apa d<strong>in</strong> sol <strong>pentru</strong> stratul de adancime cu o ecuatie diferentiala simpla care ia <strong>in</strong> considerare cele<br />
mai importante fluxuri care determ<strong>in</strong>a bilantul de apa d<strong>in</strong> sol. In acelasi timp, varianta aleasa pe<br />
baza solutiilor aproximative ale ecuatiei Richards permite descrierea cu acuratete a evolutiei<br />
umiditatii d<strong>in</strong> sol <strong>pentru</strong> stratul de sol de la suprafata si aceasta are un impact favorabil <strong>pentru</strong><br />
calcularea evaporatiei actuale d<strong>in</strong> sol. In plus, rezultatele au demonstrat eficienta functiilor de<br />
pedotransfer propuse <strong>pentru</strong> a estima parametrii si <strong>pentru</strong> a oferi performante satisfacatoare ale<br />
<strong>model</strong>ului de bilant de apa d<strong>in</strong> sol care ia <strong>in</strong> considerare diferitele proprietati hidraulice al solurilor.<br />
In concluzie, schemele propuse permit diferentierea umiditatii d<strong>in</strong> sol la scara baz<strong>in</strong>ului hidrografic<br />
pe baza catorva factori: proprietatile hidraulice ale solului, parametri de cultura si variabile<br />
topografice care <strong>in</strong>fluenteaza fluxurile potentiale si actuale de transpiratie si evaporatie.<br />
