Estuary Catchment Total Suspended Solids Loads

Annual average loads of Total Suspended Solids have been estimated for all 184 NSW coastal catchments. Land use in each catchment was assigned to one of nine categories and event mean concentrations of TSS for each land use determined from literature review and field studies. Flow was estimated using a modified version of the 2CSalt catchment rainfall-runoff model. Using these two inputs, loads under current land use and hypothetical natural land use were derived.

针对新南威尔士州（New South Wales, NSW）全部184个沿海集水区，研究人员已估算得到总悬浮固体（Total Suspended Solids, TSS）的年平均负荷。将各集水区的土地利用划分为9大类之一，并通过文献综述与野外实地研究，确定了各类土地利用对应的TSS事件平均浓度。径流量采用改进版2CSalt集水区降雨-径流模型进行估算。基于上述两项输入参数，可推导得到当前土地利用情景与假设自然土地利用情景下的TSS负荷。
