This Project aims to investigate drivers and triggers of variable streamflow response during and after drought and develop modelling strategies and model structures more robust to changing streamflow response. In many catchments during the Millennium Drought, streamflow generation was less than expected and hydrologic models performed poorly. After the drought, streamflow generation is yet to recover in some catchments. This Project expects to generate new knowledge about variable streamflow response to drought and develop strategies and models to robustly simulate runoff during and after changed conditions, which should provide significant benefit via better understanding and modelling of streamflow response under changing conditions.

该项目旨在调查干旱期间和干旱之后可变径流响应的驱动因素和触发因素，并开发更稳健的模型策略和模型结构，以应对不断变化的径流响应。在千年干旱期间，许多集水区的径流量低于预期，水文模型表现不佳。干旱后，一些集水区的径流量尚未恢复。该项目预计将产生关于可变径流对干旱的响应的新知识，并开发策略和模型，以在变化条件期间和之后稳健地模拟径流，这将通过更好地理解和模拟变化条件下的径流响应提供显着的好处。
