Calibration and analysis of a hydraulic model of the Neris stormwater network

Abstract

This article analyses how the hydraulic model of the stormwater drainage network corresponds to the actual measured flow rate data. The primary scientific challenge is to develop a hydraulic model that accurately aligns with real stormwater flow rates and precipitation data. The analysis of hydraulic models is essential for accurately predicting surface runoff flows, ensuring network efficiency, and reducing flood risks in urban areas. The study employed the rational calculation method, integrated into the CivilStorm software, to analyse actual (measured) precipitation data obtained from meteorological stations and flow rate readings from the outfall flow meter. The results revealed that precipitation intensity variability can significantly impact the accuracy of modelling outcomes.
