**5. Conclusions**

Over the studied period, the soil moisture values at the soil profile varied in all the sites sampled. There are some similitudes grouping the areas in those sites in the north, south and in the archaeological zone. However, there are not only different soil conditions, but also vegetation, climate and topography differences. Vegetation varies from low to middle jungle with roots growing horizontally. Climate varies dividing the area in quadrants with important temperature and precipitation variations.

Soil moisture result using TDR\_CS and FDR\_Dec sensor in a datalogger systems was more similar after 10 cm depth. At 2.5 and 5 cm, there is a high variability mainly associated to the actual conditions in the soil surface. However, the seasonal effect under soil moisture demonstrated that FDR\_Dec was very sensitive in periods of high rainfall and overestimated soil moisture during the dry season. Something similar happened using the FDR\_Div sensors, which overestimated significantly in the dry season. The best result was provided by the CS616 Campbell sensors for over the whole study period. Looking at the soil moisture values along the depth profile, it was effectively probed that when it has a heterogeneous soil in the unsaturated zone, texture is determinant. If one did not consider these, a wrong calibration could be obtained and soil moisture values would have nonsense. Another important aspect to be considered is the possible disturbance of the soil at the moment of the sampling for the gravimetric method. Also, raw values from the different devices need to be calibrated; otherwise, any soil moisture value could be obtained. Even if the calibration was not appropriate under dry conditions, it is necessary to consider the karstic nature of the soil in the area; thus, infiltration could occur at different deep levels.
