| Research Abstract |
This study aims to study the distribution of contaminants in the Haina River and Ozama-Isabela River that flow through Santo Domingo, Dominican Republic into the Caribbean Sea by using chlorophyll-a (Chl-a) and suspended sediment (SS) as markers and ALOS AVNIR-2 satellite sensor data. In situ spectral reflectance/Chl-a and SS datasets obtained from these rivers were acquired in March 2011 (Case A) and June 2011 (Case B) to develop the estimation algorithm of Chl-a and SS using AVNIR-2 data. The algorithm was applied to AVNIR-2 data in November 2010 for Case A and August 2010 for Case B. In both cases, the reflectance ratio of AVNIR-2 band 4 and band 3 (AV4/AV3) and the reflectance of AVNIR-2 band 4 (AV4) were effective for Chl-a and SS estimation. The Chl-a and SS mapping obtained by AVNIR-2 data corresponded to the field survey data. Finally, an outline of the distribution of contaminants at the mouth of the river that flows into the Caribbean Sea was obtained for both rivers.
