| dc.description.abstract | Most of the coastal lagoons and creeks in Lagos State are hubs of transportation and logistics networks for movement of goods and services. However, the coastal environment is marred with the problems of marine pollution and clogging of most waterways, particularly with respect to algal blooms and waterhyacinth. Thus, posing vulnerable threats to human activities, aquatic lives, and coastal transportation system (CTS). There exists a dearth of the connection of these water-hyacinth with coastal transportations in most studies. Moreover, conventional and remotely sensed data collections to detect these pollutants, their spatial dispersion, and potentials of using Landsat data in a geomatics environment are not fully explored. In this study, chlorophyll-a, a strong indicator of these pollutants was delineated using geomatics techniques for save CTS in Lagos State. Landsat 8 imageries of two seasons of the year were processed to detect and estimate the chlorophyll-a concentrations. Thereafter, maps portraying the chlorophyll-a distribution were produced, the dynamics of the chlorophyll-a concentration analyzed statistically and in the context of coastal navigable routes. Results showed the spatial spread of chlorophyll-a in the study areas is higher during the dry season. The results were validated by ground-truthing during satellite overpass. This implies that the techniques adopted are useful in mitigating these pollutants by marine stakeholders for sustainable CTS and marine resource management. | |
