dc.description.abstractU radu se najpre, korišćenjem principa dimenzione analize, razmatra slobodno, nepotopljeno prelivanje preko širokog praga sa pravouglim uzvodnim licem. Potom se, primenom jednačine sila (dinamičke jednačine), izvode uopšteni, teorijski izrazi za određivanje koeficijenta protoka preko širokog praga prvo u kanalu sa nagnutim, a zatim u kanalu sa horizontalnim dnom. Na kraju se vrednosti koeficijenta protoka, dobijene na osnovu rezultata laboratorijskih eksperimenata za tri različita nagiba dna, porede sa ekvivalentnim vrednostima za horizontalno dno i izvode odgovarajući zaključci o uticaju nagiba dna na vrednosti koeficijenta protoka C_Q.sr
dc.description.abstractThe free flow over a rectangular broad-crested weir is described first, using the basic principles of dimensional analysis. Subsequently, from the momentum equation, general expressions are derived for the discharge coefficients for broad-crested weirs in both sloping and horizontal channels. Then, for three different channel slopes, values of discharge coefficients obtained from experiments in a laboratory flume with adjustable bottom slope are compared with corresponding values in a horizontal channel. Finally, conclusions are proposed about the influence of the bottom slope on the discharge coefficients.sr
