Hydraulic Model Build

DWS can assist you with building a hydraulic model for your Water, Sewerage or Stormwater networks. The build process involves creating a computer-based simulation of the hydraulic system. The model can be used to analyse the behaviour of the system under various conditions which provide valuable insights into the performance of a complex hydraulic system and help to optimize design, operation, and management decisions.

Here are some of the key steps involved in building a hydraulic model:

Data Collection: Gather relevant data about the hydraulic system being modelled, including geometric data (such as pipe diameters, lengths, and elevations), operational data (such as flow rates, pressures, and boundary conditions), and environmental data (such as temperature, and roughness coefficients). This data can be obtained from field surveys, engineering drawings, GIS databases, or historical records.
Model Domain Definition: Define the boundaries and components of the hydraulic system to be modelled. This may include pipes, pumps, valves, reservoirs, tanks, junctions, and other hydraulic elements. Use hydraulic modelling software to create a digital representation of the system’s geometry and topology.
Geometric Modeling: Build a geometric model of the hydraulic system by accurately representing the spatial layout and connectivity of its components. This involves creating nodes to represent junctions and vertices of pipes, and links to represent the pipes themselves. Specify attributes such as pipe lengths, diameters, roughness coefficients, elevations, and material properties.
Boundary Conditions: Define boundary conditions at the inflow and outflow points of the hydraulic system, including flow rates, pressures, water levels, or other hydraulic parameters. Specify any external influences such as pump operations, control valves, or reservoir levels that affect the system’s behavior.
Model Calibration: Validate and calibrate the hydraulic model by comparing its predictions with observed data from the real-world system. Adjust model parameters (such as pipe roughness, pump curves, or control settings) to improve the match between simulated and observed hydraulic behaviour. Iteratively refine the model until it accurately represents the hydraulic characteristics of the actual system.
Scenario Analysis: Use the calibrated hydraulic model to analyse different scenarios and conditions that may affect the system’s performance, such as changes in demand, infrastructure upgrades, operational changes, or emergency scenarios (such as pipe breaks or pump failures). Evaluate the impacts of these scenarios on flow rates, pressures, water quality, and other relevant parameters..
