Abstract(s)
Water is a vital resource for mankind used in activities such as agriculture,
industry and domestic activity. Irrigation is one of the most consuming
water resources in human activity. Irrigation canals are characterized for being
spatially distributed crossing different administrative regions. As water is becoming
a scarce and valuable resource, efficient engineering water conveyance
networks are required. In this paper a discrete state space for modeling openchannels
is presented. The well known Saint-Venant equations are first linearized
for a steady state and then discretized using the Preissmann scheme. The resulting
model is shown to be computational simple and flexible to accommodate
different type of boundary conditions, in flow, water depth or hydraulic structures
dynamics, which are important features for modeling complex water conveyance
systems. The hydraulic model also offers monitoring ability along the canal axis
and can therefore be integrated in fault diagnosis and tolerant control strategies.
The model is validated with experimental data from a real canal property of the
Evora University.
