Analysis of thermal conductivity in a seasonal flooded forest in the northern Pantanal

Abstract

Research involving the flux of energy in the soil has been intensified in order to increase the understanding of the geophysical behavior of the Pantanal-Brazil. In present study was examined the seasonal variation of the thermal soil conductivity in the Pantanal for the study of energy flow in the soil to Pantanal region. .ºC -1 respectively. The seasonal variation of the thermal conductivity of the soil was 30.68% higher in the wet season than in the dry season due to soil moisture in the wet season. It was also noted that the seasonal variation of temperature in the soil layer was higher in the wet season than in the dry season due to a lower incidence of solar radiation in this season. .ºC -1 e 6,65W.m -1 .ºC -1 . A variação sazonal da condutividade térmica do solo foi 30,68% maior no período chuvoso do que no seco, em decorrência da maior quantidade de água no solo na estação chuvosa. Observou-se também, que houve variação sazonal da temperatura do solo nas camadas estudadas, sendo maior no período chuvoso do que no seco, devido à menor incidência de radiação solar nesse período.
