Climate change impact assessment on artificial wetlands

Remote sensing has been widely used for determining climate changes characteristics, also in wetland studies. Aster images
from 2002 and 2008 demonstrated that the water surface in a wetland located at Guasca Municipality in Colombia
increased from 3934m2 to 126403m2 respectively at 15m resolution. Modis images 13A3 allowed calculation of Normalized
Difference Vegetation Index (NDVI) on a monthly basis from June to November 2008 with a resolution of 1 km. The results
showed how variables such as Net Radiation, Temperature and Rain explained 83 percent of the NDVI monthly changes (data
obtained from the meteorological stations HOBO and Campbell placed close to the wetland). In addition, Potential Evapo-
transpiration was calculated with formulas and compared with the ILWIS software with similar results with averages of 7.7 mm/
day. Groundwater level fluctuations on a daily basis were studied as well as data from a Piezometer placed next to the wetland
during the same time period. Data was fitted with Rain changes with multiple regression analysis and time series, with R2 of
0.98. Groundwater temperature and conductivity changes were also analyzed; no significant changes over the studied time
were noticed. However, conductivity changes were influenced by NDVI, Rain and Evapotranspiration with polynomial fittings
greater than 90%. November was characterized by increasing NDVI, meaning that more agriculture took place. Agricultural
runoff could increase conductivity due to additional phosphate and nitrate ions. Surface water quality analysis was performed
to determine the possible contaminants. The results show that Coliforms were the most significant contaminants.
