Ecological models as support systems to decisions in lake management planning

Modelling eutrophication in lake ecosystems: A review

“…Imboden, 1974;Schnoor and O'Connor, 1980;Vollenweider, 1975). These models are called "input-output" models (Vollenweider, 1975) or blackbox models (Teruggi and Vendegna, 1986) and are sometimes considered as empirical models whereas their structure is directly deduced from dynamic equations of biogeochemical processes. The data that generally come from a group of lakes, are only used to identify the model parameters with statistical methods.…”
