| The results exposed in the present work are framed in the activities of Internal Scholarship of CONICET that is developed in the Institute of Geography Applied in National San Juan University. The General Objective of the investigation work was based on application of the systemic approach, for the analysis of natural systems of “precordilleranas” hydrographic river basins. In this case it was chosen like object focused to the geomorphologic object. Satellite Techniques, Manual and Digital Mapping with ITC Symbol, Direct Wide Observations and SIG with Software Ilwis 3.3 Were used . It was selected as study unit the area drained by the river, that is located in Central Precordillera of San Juan Province, in virtue to fort influences new tectonics,... |

| Damage from tropical cyclones can have major consequences for coral reef structure and ecology, as well as for human communities and human uses of coral reef resources. Remote sensing with high resolution multispectral satellite images can be used to asses large scale cyclone damages on coral reef areas. SPOT images of the almost atoll of AITUTAKI (Cook Islands) taken in june 1986 and february 1987 after the passage of Cyclone Sally near the island in january, were transformed and subjected to a textural analysis, and then compared to asses damage on the reefs and lagoon.New shallow sand and rubble deposits showed increased reflectance, while lower reflectance seemed associated with damage to reef structure, scouring in the lagoon, deposits of terrestrial... |
