abstract = "Side weirs are a type of hydraulic structures used to
divert or measure flows in open channels. In this
chapter, two machine learning (ML) methods, named
artificial neural network (ANN) and multigene genetic
programming (MGGP), were applied to develop ML-based
methods for estimating discharge coefficients of side
weirs installed in rectangular and trapezoidal canals
for subcritical flow. According to the literature, the
latter ML method is the first time to be used for this
purpose. For the comparative analysis, a large
experimental dataset was collected from previous
studies available in the literature. Unlike ANN, MGGP
provides an explicit equation that incorporates all
parameters that affect discharge coefficients of a side
weir. Although the results indicate that ANN performs
slightly better than the MGGP-based model for this
application, the explicit estimation model developed by
MGGP can be further used in numerical modeling in river
engineering and open channel designs",
