Multiple linear regressions are used to relate average annual runoff to average annual rainfall and areal potential evapotranspiration (PET) using data from 213 catchments grouped according to location in six of the major Drainage Divisions of Australia. A method is presented for estimating daily runoff from daily rainfall data using the AWBM model, which self-calibrates its surface storage par...

The Australian water balance model (AWBM) is a catchment water balance model that calculates runoff from rainfall at daily or hourly time increments. The daily version iss used for water yield and water management studies; the hourly version is used for design flood estimation. This paper describes the origin and development of the AWBM beginning with elementary modelling components of saturati...

A new method of calibration of the Australian Water Balance Model (AWBM) daily rainfall-runoff model allows for errors in the estimation of areal rainfall over the catchment. The result of applying the method to a group of gauged catchments is the production of a single set of parameter values for the AWBM that can be used with any catchment in the group, or used to estimate runoff on ungauged ...

Abstract Daily River Malaba flows recorded from 1999 to 2016 were modelled using seven lumped conceptual rainfall–runoff models including AWBM, SACRAMENTO, TANK, IHACRES, SIMHYD, SMAR and HMSV. Optimal parameters of each model obtained an automatic calibration strategy. Mismatches between observed assessed a total nine “goodness-of-fit” metrics. Capacity the reproduce historical hydrological ex...

Hydrological modelling at a catchment scale was conducted to investigate the impact of climate change and land-use individually in combination with available streamflow Painkalac using an eWater Source hydrological model. This study compares performance three inbuilt conceptual models within Source, such as Australian water balance model (AWBM), Sacramento GR4J for simulation. The three-model p...

Climate changes, especially its impacts on temperature, precipitation and evaporation, have large effects on water resources. In recent years, water authorities in Australia imposed various water demand management strategies including mandatory water restriction to reduce water demand as the dam storage levels dropped quite low due to the prolonged droughts which affected the country for about ...

Lumped-conceptual rainfall-runoff models are a ‘stock in trade’ tool for those working in the water industry and allied fields. However, there are many alternative models available, and sometimes multiple implementations of the same model. The consequence of this is a plethora of models with different operational features and different access arrangements. Similarly, there are a variety of opti...
