| ABSTRACT This article describes the cartographic layer construction process of Colombian Caribbean coastal wetlands at a scale of 1:100,000 and the results obtained in terms of their quantification and typing. Two cartographic layers were constructed and subsequently joined, one of the permanent water bodies and another of temporary water bodies and associated coverages. The layers were generated by multitemporal analysis of 45 Landsat 8-OLI satellite images, based on the NDVI index, uncertainty models by superposition of cartographic attributes, and a flood frequency consultation model on ALOS PALSAR 1 images. As a result, 576,279 ha of coastal wetlands were delimited (1.9 % of total wetlands in Colombia), of which 20.4 % are within protected areas. The... |

| ABSTRACT The present study evaluated the short-term response (<six months), of water physicochemical parameters to hydrological rehabilitation (HR) of clogged channels in mangrove of Cispata, Colombian Caribbean. Between September 2018 and September 2019, we measure the water physicochemical parameters before and after the HR. The index of marine and coastal water quality (ICAMPFF) in channels and swamps was calculated. Before the HR, in some stations, water quality was very poor, in other inadequate, and in other acceptable; after five months of HR in all stations, water quality became acceptable. After HR, the salinity and temperature of the water within the mangrove decreased to adequate values for the mangrove seedlings. In the short term, HR... |
