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...

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...

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...

according to variety of accessible hydrological models, evaluateing the efficiency of models for different management objectives are essential. therefore, models with simple structure and using minimal input that can provide an acceptable result can serve as an effective tool to watershed managers. hence, the objective of this research is to evaluate the relative performances of the lumped conc...

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...

With the wide range of models available, hydrologic modellers are faced with the choice of which model is best applied to a catchment for a particular modelling exercise. Assessing the relative performance of competing models can be difficult given the limited data that is available and further complicated by difficulties in obtaining a unique set of values for the model parameters. Traditional...

Hydrological reaction to climate change anticipates water cycle alterations. To ensure long-term availability and accessibility, it is essential develop sustainable management strategies better hydrological models that can simulate peak flow. These efforts will aid in resource planning, management, mitigation. This study develops compares Sacramento, Australian Water Balance Model (AWBM), TANK,...

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 ...

Parameters’ acquisition is a key step for the distributed hydrological model when simulating a basin. Based on remote sensing technology, this article proposed a parameters acquisition method of distributed hydrological model. That is extracting the important ground objects’ information from the images to obtain some parameters of the model. This article also used the hierarchical classificatio...
