This project aims to investigate how large rivers are affected by changing atmospheric temperature. Large inland rivers are the main source of water supporting ecological functions, economies and societies. This project will quantify the size and age of abandoned river channels in the Murray-Darling Basin (MDB) of southeast Australia and the Atuel/Diamante basin of Argentina. We will use this to reconstruct a history of changes in river discharge and relate this to climate. Novel climate and hydrological modelling will then be used to simulate the impact of temperature changes on catchment runoff and river discharge. Such information is vital for decision-making, planning and water resource allocation in the MDB and elsewhere.

该项目旨在研究大型河流如何受到大气温度变化的影响。大型内陆河是支持生态功能、经济和社会的主要水源。该项目将量化澳大利亚东南部Murray-Darling盆地（MDB）和阿根廷Atuel/Diamante盆地废弃河道的大小和年龄。我们将用它来重建河流流量变化的历史，并将其与气候联系起来。新的气候和水文模型将用于模拟温度变化对集水径流和河流流量的影响。这些信息对于多边开发银行和其他地方的决策、规划和水资源分配至关重要。
