This code has the implementation of a novel methodology to locate and quantify entrapped air pockets created during pipe-filling events often found in intermittent water supply systems. A new numerical model capable of simulating the air pocket creation, dragging and entrainment has been proposed, AirSWMM, was implemented as an extension of the Stormwater Management Model (SWMM) with stochasticity of air pocket formation reproduced by simulations with different air entrainment rates. The obtained numerical results show that the proposed model, even though based on a single-phase one-dimensional flow, can accurately locate and approximately quantify the entrapped air pocket volumes.
