About

In this 8‑session course, participants build practical, end‑to‑end capability in rainfall–runoff modelling using the free HEC‑HMS (Hydrologic Modeling System) software tool. The course is designed to introduce the core concepts behind hydrologic modelling while guiding participants through catchment delineation, basin model setup, meteorological inputs, and the application of loss, transform, and channel routing methods across a range of catchment types.

Each session blends essential background theory with hands‑on, workshop‑style exercises. Participants work directly with real‑world datasets, develop complete HEC‑HMS model configurations, and explore calibration, parameter selection, and sensitivity testing. The structured, step‑by‑step format ensures participants gain confidence in building, running, and refining models that support robust hydrologic assessments.

By the end of the Masterclass, participants will be able to independently construct and apply HEC‑HMS models for engineering, environmental, and water‑resource applications. The course is ideal for engineers, hydrologists, environmental scientists, and practitioners seeking practical, job‑ready modelling skills using industry‑standard tools.

Course Overview

This practical HEC‑HMS training course provides participants with the end-to-end skills in rainfall–runoff models. Through guided, hands‑on workflows, participants develop basin models, apply loss, transform, and routing methods, calibrate parameters, and run sensitivity analysis, building practical capabilities for hydrologic modelling and water‑resource assessment.

Learning Outcomes

In this course, you will be able to:

Develop complete HEC‑HMS basin and meteorological models for a range of catchment types.
Apply loss, transform, and routing methods to simulate rainfall–runoff processes.
Calibrate model parameters and assess model performance using industry‑standard approaches.
Run sensitivity analysis to understand model behaviour and refine assumptions.
Produce robust hydrologic assessments suitable for engineering and water‑resource applications.
