Abstract

Inventia se refera la o metoda pentru determinarea indirecta a coeficientului de rugozitate, în special al galeriilor hidrotehnice, necesar la dimensionarea din punct de vedere hidraulic si la calculul productiei de energie a unei amenajari hidroenergetice. Metoda pentru determinarea indirecta a coeficientului de rugozitate al galeriilor hidrotehnice consta dintr-o prelevare a unui cuplu de doua fotograme de pe suprafata galeriei si vizualizarea lor pe un stereocomparator. Ridicîndu-se un numar cît mai mare de puncte, se masoara niste abateri fata de un plan mediu si se calculeaza un parametru ce caracterizeaza suprafata supusa determinarii. în functie de valoarea parametrului calculat, cu ajutorul unei curbe etalon, se determina valoarea coeficientului de rugozitate.
