Modelagem dos impactos ecológicos do projeto hidroviário da Lagoa Mirim (Brasil-Uruguai), baseada em Raciocínio Qualitativo

Abstract: This study is an application of the scientific mediation process through modeling the physical, chemical and biological impacts of a waterway construction in Mirim Lagoon. Qualitative modelling process, based on Qualitative Reasoning, was conduced to better understand the ecological impact on water environment. The qualitative reasoning simulation show clear trends towards a loss of the physiochemical natural characteristics of the lagoon ("backwater effect") and a decline of macrophyte, invertebrate, water bi… Show more

“…Studies on shallow lakes (e.g., Bengtsson & Hellström, 1992;Lövstedt & Bengtsson, 2008) have demonstrated that waves induced by winds are common, and the waves and currents generated during higher kinetic events such as storms can resuspend and transport the sediment of the whole lake. Higher water turbulence due to constant and strong winds associated with a shallow condition is attributed to Mirim Lake (Goulart & Saito, 2012). In this sense, the reworking of bioclasts by wind-induced waves can be expected on the lake shore.…”

“…A De um lado a globalização representa, do ponto de vista econômico, a valorização seletiva do espaço (BECKER, 1991), promovendo conflitos e competições regionais, que resultam no aumento dos custos ambientais, com a intensificação da poluição do ar, água e solo, e do esgotamento de recursos naturais não-renováveis e a disseminação de espécies exóticas invasoras (EHRENFELD, 2003;GOULART & SAITO, 2012). Por outro lado, essa mesma globalização induz, contraditoriamente, a novas conformações de integração e enfrentamento conjunto.…”
