Will rivers be smaller when the climate is hotter?

点击翻译按钮获取中文摘要

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.
