毕业论文代写:莫尔顿湾的水文系统

根据“Master modelers”(2002,第24页)这篇文章,莫尔顿湾的水文系统可以从输运和泥沙模型的角度来看待。下雨时,海湾会接收来自布里斯班、派恩、洛根和卡波杜尔河的沉积物和其他排放物。这些污染物水平移动并分散到莫尔顿湾。由于没有适当的污染物排放,它们随后被重新悬浮并沉积在海湾楼层内。沉积物形成了一个死区,“泥块”,在莫尔顿湾造成浑浊和盐度(《大师模型》,2002年,第24页)。

Davis & Koop(2006)断言,降雨后的河口富营养化导致了来自集水区和其他入口河流的营养物、沉积物和化学物质对水的污染。流域的生物物理过程对淡水和河口的营养物释放和运移、混浊、分层和藻华等都有一定的贡献。摩顿湾的大多数水域都富含有机营养物,这些营养物来自农业活动,导致藻华和蓝藻爆发(Davis & Koop, 2006年,第24页)。对摩顿湾富营养化和排水不良的日益关注,激发了旨在建设排水网络的管理项目。系统运行方式的本质导致营养物和微量沉积物的扩散及其随后的浓度(Davis & Koop, 2006, p. 32;Cox & Preda, 2005, p. 174)。

According to the article, ‘Master modellers’ (2002, p. 24), the hydrological system of the Moreton Bay could be viewed from the perspective of a transport and sediment model. When it rains, the Bay receives sediment loads and other discharges from Brisbane, Pine, Logan, and Caboolture rivers. These pollutants are horizontally moved and dispersed into the Moreton Bay. With no proper drainage of pollutants, they are later re-suspended and deposited within the Bay floors. The sediments form a dead zone, ‘mud patch,’ causing turbidity and salinity in the Moreton Bay (‘Master modellers,’ 2002, p. 24)

Davis & Koop (2006) assert that the estuarine eutrophication following rainfalls results in contamination of water by nutrients, sediments, and chemicals from within the catchment and other inlet rivers. The biophysical processes in the catchment contribute to nutrient release and transport, turbidity, stratification, and algal blooms on the freshwaters and estuaries. Most of the Moreton Bay waters are enriched with organic nutrients from agricultural activities that contribute to algal blooms and cyanobacterial outbreaks (Davis & Koop, 2006, p. 24). The growing concern of eutrophication and poor drainage in Moreton Bay has inspired management programs aimed at constructing drainage networks. The nature of how the system operates leads to diffusion of nutrients and trace sediments and their subsequent concentration (Davis & Koop, 2006, p. 32; Cox & Preda, 2005, p. 174).
