  This study inspects the light and radial-velocity curves of the eclipsing
binary AV Del. In comparison with other studies already done, the study shows
that the absolute elements, fundamental orbital and physical parameters of the
system can be determined using the Wilson-Devinney code. Using these
parameters, the configuration of the system is presented. Then, an accretion
disc model for the system is introduced by using the SHELLSPEC code. The
results indicate that AV Del is a semi-detached system in which an optically
thick accretion disc is surrounding the primary star. The outer radius of the
disc is 8.0 R_sun}, corresponding to a distance of 1.1 R_sun} from the surface
of the secondary. Also, the temperature of the disc is calculated to be T=5700
K.
