HidroModelagem
Complete hydraulic modeling platform for water distribution networks in QGIS: builds and runs EPANET models, diagnoses the network by simulation or by hydraulic head alone (elevation and demand), recommends air-valve locations, automatically suggests pressure-reducing valve (PRV) and isolation-valve locations for pressure zoning and DMA sectorization, calibrates the model, extracts elevations from the Copernicus DEM and analyzes water losses, PRV, sectorization, DMA, DMC using the IWA methodology.
HidroModelagem is a hydraulic engineering platform for QGIS focused on water distribution networks. It builds EPANET models from node and pipe layers (or opens an existing .inp file) and runs steady-state or extended-period simulations, bringing pressures, flows, velocities and head loss (Hazen-Williams) to the map, with automatic highlighting of pipes that need reinforcement. It goes beyond simulation: it diagnoses the network in plain language, evaluates an area by hydraulic head alone - using only elevation and demand, with no need to simulate - and recommends where to install air valves in transmission mains and networks (high points, slope changes and long stretches). It also includes: elevation extraction from the Copernicus GLO-30 DEM directly into the node attribute table; Thiessen polygons and automatic identification of critical sectors; assignment of service connections to the nearest influence node; roughness calibration against field-measured pressures; hydraulic calculators (design flows, pipe and pump sizing, water hammer, fire flow); and water-loss analysis using the IWA methodology - water balance, ILI index, FAVAD (pressure management), economic level of leakage and energy efficiency. Requires the WNTR library for EPANET simulation.
