Avaliação da influência da precipitação pluviométrica no mapeamento das características da paisagem do sítio arqueológico AP-MA-05/Amapá e sua importância social e histórica

Abstract

This study evaluated the influence of rainfall in mapping landscape features of the archaeological site AP-MA-05 and the contribution of its social importance and historical. To obtain the data was used geophysical method of electrical resistivity in an area of UNIFAP (Federal University of Amapá) of 10 x 20 meters. The rainfall data were collected in INMET station Macapá. Data analysis was performed with use of statistical and geostatistical methods. In rainy season, the soil resistivity presented a minimum of 198.7 ohm.m and maximum values of up to 3946 ohm.m, averaging 1188.87 ohm.m. In the less rainy season observed values were 394 ohm.m (minimum) and 5863 ohm.m (maximum), averaging 2078.31 ohm.m. This shows the influence of rainfall on the apparent resistivity, since the more intense were the rains that occurred at the time of obtaining data, minors were the values of electrical resistivity. A survey on the social perception of the UNIFAP students and interviews with teachers responsible for the site in question, it was found that the level of awareness of students varies according to the course of affinity degree in archeology.
