Abstract
This paper presents a non-elastic matrix model to calculate hydraulic networks,
based on a method created by Nahavandi and Catanzaro (Journal of Hydraulics
Division, 99(HY1), pp.47-63, 1973). It is a method that calculates the discharges
and pressure heads in hydraulic networks for the steady state, for the extended
period and for the transient state. This method has advantages concerning the
Cross method, because the latter does not allow the calculation of transient
situations such as the settings of valves, the starting and stopping of boosters, the
branch ruptures, etc. The applicability of the method created by Nahavandi and
Catanzaro was enhanced, because the programming and input data to consider
the presence of valves, reservoirs or boosters in the hydraulic network were
developed. Furthermore, the mathematical formulation and programming to
calculate the extended period and transient state were also developed. The matrix
method is working well, because the model was applied to calculate some
hydraulic networks used as examples and the values calculated by the model are
similar to the ones obtained from the technical literature.
Keywords: hydraulic networks calculation and operation, software.
1 Introduction
In the water resources field, the unbalance between water supply and water
demand obliges more and more elaborated solutions from the engineer. As
countries develop, problems related to water, like cities supply, water
transference among watersheds and mainly the lack and the difficulty to obtain
