Kurzbeschreibung (Abstract)
Satellite imagery data is increasingly available free of charge, in improved spatial and temporal resolution. For the realization of environmental impact assessments and water balances it is becoming a valuable resource, especially when studying large or remote areas in absence of ground data. In this contribution multispectral and radar satellite images are used to study the changes in surface area and water table of Lake Cocibolca (Lake of Nicaragua) during the last decades and the environmental impact of the construction of an interoceanic canal through the Nicaraguan isthmus. Based on surface areas of the lake derived from multispectral Landsat satellite images and lake water levels gained from radar altimetry data, a characteristic volume-water level curve was constructed. This curve may serve as a planning instrument for future use of the lake’s water. Furthermore, the land use affected by the planned interoceanic canal is assessed applying an unobserved and expert-advised classification using Landsat satellite images. Thereby, the affected population, road network, agricultural and natural areas are identified and quantified. Finally, a comprehensive water balance for the river basins along the canal route based on multispectral and radar satellite images is presented. As a result, natural water availability and the amount of water required for canal operation is compared.
