in the past decades, much effort has been devoted to simulation of the rainfall-runoff process. hydrological models are simplified representations of the natural hydrologic system. in each case, the choice of the model to be applied depends mainly on the objective of the modeling but also on the available information. the relative performances of two lumped conceptual-based hydrology models (ta...

climate change is one of the most important factors that will affect different parts of human life on earth and will be adverse effects on environmental resources, economic, social and especially water resources, with changes in rainfall and timing of runoff amount.one of the strategies to mitigate the effects of climate change is to assess its effects on precipitation, temperature and runoff i...

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...

It is widely recognised that the Murray-Darling Basin (MDB) in south-eastern Australia has been in the grip of a serious drought for many years. Over the period 1997−2006, mean annual rainfall has been approximately 16 percent lower than the long-term (1895−2006) average across the MDB. Runoff has been 39 percent lower over the same period. The continuing drought in the MDB has brought the need...

The IHACRES model has been successfully applied to many catchments across the UK including regionalization studies (e.g. Sefton and Howarth, 1998; Littlewood, 2003). However, while the previous formulation of the non-linear module performs well in calibration and simulation, the module has some identified deficiencies in the representation of the impacts of climate change on volume of streamflo...

this study aims to evaluate effects of two downscaling methods; change-factor and statistical downscaling on therunoff of the azam-harat river located at yazd province (with an arid climate) of iran, under the a2 emission scenariofor the period of 2010-2039. for this purpose, cgcm3-ar4 model; a rainfall-runoff conceptual model, ihacres; twodownscaling models, change factor and lars-wg were appl...

The effects of climate change have been observed in the Murrumbidgee River basin, which is one main river basins southeast region Australia. study area largest and most important agricultural production within Murray Darling Basin (MDB). It produces more than AUD 1.9 billion products annually accounts for about 46% Australia’s total production. Since economy largely depends on its natural resou...
