Restoring hydrological connectivity of surface and ground waters: Biogeochemical processes and environmental benefits for river landscapes

本项目研究恢复横向水文连通性，以改善洪泛平原的结构和功能。溪流与浅层地下水和洪泛平原之间的联系对于维持河流景观至关重要。退化的土地和水管理做法加上自然极端气候，切断了这种联系。恢复水文连通性对于补充地下水储存和增加影响基本河流过程的基流至关重要。我们的项目采用一种创新的可持续农业方法，将多学科科学和行业专业知识结合起来，研究次级洪泛平原渠道和河内结构对河流地下水过程的生物地球化学和生物物理影响。

This project examines the restoration of lateral hydrological connectivity to improve floodplain structure and function. The connections between stream flows and both shallow groundwaters and floodplains are critical in sustaining river landscapes. Degrading land and water management practices compounded by natural climatic extremes have severed this link. Restoring hydrological connectivity is vital for replenishing groundwater storage and increasing base flows that affect fundamental riverine processes. Using an innovative approach to sustainable agriculture, our project unites multidisciplinary scientific and industry expertise to investigate the biogeochemical and biophysical effects of secondary floodplain channels and in-stream structures on riverine groundwater processes.
