Previous issue date: 2016-07-05 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior (CAPES) / A investiga??o da din?mica temporal do fitopl?ncton em corpos d?agua ? uma necessidade real e crescente diante dos problemas envolvendo processos de eutrofiza??o decorrente de impactos humanos. Dada a complexidade dos fen?menos envolvendo o crescimento fitoplanct?nico, faz-se necess?rio o uso de modelos matem?ticos em softwares que simulem as estruturas e processos relacionados a este crescimento. Neste trabalho, utilizamos o modelo IPH-ECO (vers?o 0-D), software que integra os processos hidrodin?micos, de qualidade da ?gua (limnologia) e de biologia das esp?cies aqu?ticas. O ambiente estudado foi a lagoa costeira de Extremoz que abastece a capital Natal (RN), durante o per?odo de 07/2012 a 08/2013. Depois da calibra??o do modelo, utilizando a din?mica da clorofila-a como vari?vel resposta, foram simulados v?rios cen?rios alterando individualmente as vari?veis for?antes: chuva, evapora??o, vento, radia??o solar e temperatura. Os resultados mostram que a vers?o 0-D do modelo IPHECO ? insens?vel as altera??es da varia??es clim?ticas, impedindo com que esta vers?o seja usada em simula??es de polui??o ou ainda para o manejo do lago. / The investigation of temporal dynamics of phytoplankton in water bodies is a growing need because of problems involving eutrophication processes due to human impacts. Given the complexity of the phenomena involving phytoplankton growth, it is necessary, the use of mathematical models to simulate related processes and structures involved in phytoplankton?s growth. In this study, we used the IPH-ECO model (0-D version) software that integrates the hydrodynamic processes, water quality (limnology) and biology of aquatic species. Extremoz coastal lagoon was studied because this environment supplies the city of Natal (RN) during the period from 07/2012 to 08/2013. After model calibration, using the dynamics of chlorophyll-a as the response variable, we simulated various scenarios individually changing the forcing variables: rain, evaporation, wind, solar radiation and temperature. The results show that the 0-D version of the model IPH-ECO is insensitive to climatic variations, preventing this version to be used in simulations of pollution or for the management of the lagoon.
