| dc.description.abstract | The research describe about surface water ecosystem study in Merauke Papua by using multisource and
multistage remote sensing data which was splitted into two parts based on the study areas. First, it is for micro scale
spatial analysis focusing on the Rawa Biru – Torasi watershed, while the second is for macro scale spatial analysis for
Transfly ecoregionin the floodplain areas of Merauke. Multispectral approach was adopted for Landsat image analysis,
followed by field survey on the selected areas. Auxilary data used are maps, secondary documents in order to improve
understanding of the areas. Interview and discussion with related institutions (Wasur National Sanctuary, Potable
Water Services, Internal Affairs Government, Forestry Service) accordingly were carried out.
The research result showed that remote sensing imagery are usefull for surface water resources study. Physical
condition of the Rawa Biru – Torasi watershed, vegetation analysis by using multitemporal data, wetland type,
hydrological process in the floodplain were presented. Rawa Biru watershed as a resource for drinking water supply
environmentaly decreased considerably due to the species invasion, with successively dominated by hydrophilla, tebu rawa,
rumput pisau, dan Mellaleuca and sedimentation took place in the main body of swamp. Upper part of the watershed
is actually included in the Papua New Guinea, in long water resources development scheme, it need administratively
belong to one recharge areas for the watershed. | en_US |
