Integrated Water Management in the Lower Richmond Catchment

新南威尔士州里士满河口的水质与渔业、水产养殖业、旅游业和娱乐业密切相关。阿尔斯顿维尔高原的旱地园艺和低地泛滥平原的酸性硫酸盐土壤向河口排放营养丰富的酸性水。以前的研究分别处理了泛滥平原、高地和河口。这项研究将通过将地表水和地下水作为单一资源来开发下里士满水资源管理的综合集水区方法。全系统办法将有助于减轻营养丰富和酸性排水对社会经济和环境的影响。它将被转移到澳大利亚的其他“热点地区”。

Water quality in Richmond River estuary, NSW, is of critical concern to fishing, aquaculture, tourism and recreation industries. Upland horticulture on the Alstonville Plateau and drained acid sulfate soils in lowland floodplains discharge nutrient-rich, acidic water to the estuary. Previous studies have treated floodplains, upland and estuary separately. This study will develop an integrated catchment approach to water management in the Lower Richmond by treating surface water and groundwater as a single resource. The whole-of-system approach will help mitigate socio-economic and environment impacts of nutrient-rich and acidic drainage waters. It will be transferable to other "hot spots" in Australia.
