Abstract
Nowadays lack of water resources in semi–arid countries and also optimum
operation of water systems play major roles in water management decisions-makings.
River regulated reservoirs are constructed downstream of reservoir
dams with relatively low elevation appropriately to supply water to river
riparian. They are mainly used for agricultural and industrial consumptions.
However, the major difference between these and reservoir dams appear in dam
elevation as well as generated turbulent flow in the regulated reservoir by flow
diversion for various regulatory conditions. These characteristics have caused
complex flow pattern generation, which may be difficult to forecast. Physical
hydraulic models are actually constructed to obtain a better understanding of
flow behaviour and its impact on hydraulic structures. In this paper, physical
modelling of regulated reservoir dams associated with water intakes are studied
in details to establish a relationship between water discharge and the proportion
by which it is flown through the intakes. Velocity measurements were also made
to establish velocity field upstream of diversion dam as well as intakes. Optimum
water elevation in the regulated reservoir was also determined while intakes were
operating at maximum capacity.
Keywords: reservoirs, hydraulic models, physical models, flow pattern, water
intake, diversion dam.
1 Introduction
A hydraulic model cannot reproduce an equal ratio of all the prototype forces
and satisfy perfect similarity. Also practical limitations of available space, funds
