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.

该项目审查了横向水文连通性的恢复，以改善洪泛区的结构和功能。 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。 退化的土地和水资源管理做法，加上极端的自然气候，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进程的基流至关重要。 我们的项目采用可持续农业的创新方法，结合多学科的科学和行业专业知识，调查次级洪泛区通道和河流结构对河流地下水过程的地球化学和生物物理影响。
