“…Moreover, despite the high impact of the CSOs in terms of microplastic pollution, the microplastic dynamics along sewer side weirs is a topic not yet discussed in the literature, while the hydraulics of side weirs were also widely investigated in recent years [31][32][33][34][35][36].…”

One of the main sources of microplastics inside surface waters is represented by combined sewer overflows (CSOs), involving severe risks for the environment. The entry of microplastics into water bodies also depends on the characteristics of sewer diversion structures used as flow control devices. In this work, an experimental investigation was carried out to evaluate the outflow of microplastic particles, consisting of different types of nylon fibers, from a side weir located on a channel with a rectangular section. A specific methodology was developed for the fiber sampling and outflow assessment after the tests were performed. For the tested configurations, an increase in fibers discharged up to 196.15% was measured as the water flow rate increased by 62.75%, combined with an increase in the side weir length up to 40% and a decrease in the crest height up to 20%. The size and weight of the different fibers showed a low impact due to their low inertia, and their motion was governed by the water flow. An empirical equation to evaluate the fiber outflow as a function of water flow rate and side weir geometric characteristics was also proposed and calibrated for the experimentally tested ranges of the dimensionless lateral water outflow Q* = 0.51–0.83 and of the dimensionless geometric parameter S* = 0.114–0.200. These first experimental results make it possible to carry out a preliminary assessment of the impact of CSOs in terms of microplastics spilled into water bodies.

“…According to recent experiments, neural networks present predictable results in water resources hydraulic structures. Hydrological factors include rainfallrunoff modeling, flow estimates, expected reservoir inflow, suspended sediment load estimation, discharge coefficient, and reservoir performance [26][27][28][29].…”

Weirs are important hydraulic structures that have been used extensively to measure and control water flow in irrigation and drainage networks, reservoirs, sewage disposal systems, flood control, and river. These structures, such as valves, are vital components in water management in irrigation canals [1][2][3]. Weirs are different types, and they are provided with particular forms for various applications. Weir of multiple classes is offered specific conditions for numerous applications. The essential spillways are Ogee spillway, Chute spillway, Side Channel spillway,
