Introduction

DRAINS provides procedures recommended by Australian Rainfall and Runoff 2019, handling ensembles of design storms and performing designs and simulations based on upper median or upper mean outcomes.  Check the Recently-added features for details.

This Help system shows you how to understand and apply DRAINS, which designs urban stormwater drainage systems and analyses their behaviour during storm events.  DRAINS describes piped drainage networks, detention basins, open channels, and rural and urban catchments.  You can apply five different kinds of hydrological model, various design procedures and Lite or Full unsteady hydraulic models.  

These Help topics apply both to DRAINS, DRAINS Lite and to the DRAINS Viewer, and will evolve with each new release of DRAINS.  For information on how to install and apply the Viewer, please go here.
