This project aims to identify and quantify the key processes driving the generation of streamflow in ephemeral catchments with different rainfall regimes, topography, geology, and two contrasting land uses. Four ephemeral catchments in south-western Victoria will be used as a case study to identify how these catchments store and release water. Particular focus will be directed to understanding the roles of groundwater and surface runoff in supplying the streams when they flow, and how rainfall is partitioned between tree water use, groundwater recharge, and streamflow. The outcomes from experimental observations will be used to improve current hydrological models to support land and water management.

该项目旨在确定和量化在不同降雨制度、地形、地质和两种不同土地用途的短暂集水区产生径流的关键过程。维多利亚州西南部的四个临时集水区将作为案例研究，以确定这些集水区是如何储存和释放水的。将特别关注了解地下水和地表径流在溪流流动时所起的作用，以及降雨如何在树木用水、地下水补给和溪流之间分配。实验观测的结果将用于改进现有的水文模型，以支持土地和水资源管理。
