1. Introduction
Hydraulic model investigations of the structures of the Duhok reservoir (Iraq) were
carried out at the Department of Hydraulic Engineering of the Technical University
of Budapest between January 1981 and January 1982, by Professor Ottó Haszpra
and his staff.
For the final forming of the double stilling basin connecting to the morning
glory spillway system (funnel, shaft, diversion tunnel) a new solution was proposed
with excentric inflow to the upper basin and nearly homogeneous overflow to the
lower basin over a special lateral weir. (HASZPRA [2])
Briefly summarising the main characteristics of this unique solution the most
important fact to be emphasised is the energy dissipation of the water jet flowing out
152 L. HAYDE
of the tunnel combined with the change of flow direction. The angle between the
entrance direction of the inflow jet and the outflow current direction to the river-bed
is 78◦40_. The most important consequence of the proposed solution was that the
7mdiameter tunnel of the spillway system to be built in rock could have been 200m
shorter allowing significant financial savings. Nevertheless, the broken-axis stilling
basin system can make the required energy dissipation and the nearly homogeneous
velocity distribution necessary for the diversion to the natural riverbed.
After successfully completing this concrete research, based on the interest
manifested on domestic and international conferences, generalising investigations
have been started (HASZPRA [1]; HAYDE [6]; PAPP [11]) to find the different
forming of the double stilling basin systems for different breaking angles between
0◦ and 90◦. These investigations have also successfully proved the satiability of the
requirements for the whole range of breaking angles.
Between 1993 and 1997 the National Scientific Research Fund has financed
the research work headed by Professor Haszpra for the theoretical and mathematical
mapping of the phenomena. The results briefly described in this paper were
presented in the ‘dr. univ.’ thesis of the author in detailed form (HAYDE [7])
