Watershed Bounded Network Model
An advanced hydrologic modelling software package
About the model
Easy to use hydrologic modelling software
WBNM is an event based hydrologic model and calculates flood hydrographs from storm rainfall hyetographs. It can be used for modelling natural, part urban and fully urban catchments.
Model History
Behind the scenes product development
The Watershed Bounded Network Model WBNM arose out of a Master of Engineering Science project by Michael Boyd, supervised by David Pilgrim in 1973.
30+ years
WBNM has had an extensive period of continuous development giving you assurances that the data you receive is accurate and reliable.
50+ reviews
With over 50 peer reviewed publications describing calibration, validation and use of the model WBNM is an industry tried and tested product.
10,000 downloads
Proof is in the downloads. With a extensive list of high profile instituitions & bodies using WBNM will help you achieve your modelling goals.
Products
WBNM Engine
A stripped down and speed optimized version of WBNM, allowing wbnm to be used nationally and internationally as a highly capable hydrology engine and as the core engine underpinning ensemble and monte-carlo design flood estimation.
WBNM
WBNM2023 is an upgraded extension of WBNM2022, with further improved functionality to support simulation of design storms in accordance with the provisions of Australian Rainfall and Runoff 2019 (ARR 2019).
WBNM_GUI
A Graphical User Interface (GUI) has been developed to allow users to graphically construct a WBNM model. The GUI allows users to open, build and run all WBNM software from the GUI as well as import and analyse the results.
Credible & reliable
When you are used by over 3,000 people, you become recognised by industry.
WBNM is proud to be used by many academic institutions, government and semi-government organizations and some of the finest private flood consulting firms in Australia.
