RT Journal Article T1 Caracterización Geomorfológica de la Ciudad de Valera (Estado Trujillo, Venezuela) T1 Geomorphologic Characterization of Valera City (Trujillo State, Venezuela) A1 Reyes Abril, J. AB Since 1990, several problems of instability have been known in the terrace of Valera caused in the borderof the slope by the downward movement of itself. Example of this is what has happened with the structuresin the Conticinio Complex (Plata IV, 1968) which have descended from its original slope of 20 meters to 2meters. In 1999 researchers from the Geological Engineering School granted by the governmental authorities,performed several studies. Included in these was a study that described the main geomorphologic units inthe city of Valera. In this description, several aspects of the next five zones were overlooked: dissectedmountainous zones, dissected elevated hills, depositional valleys coluvio - alluvial and clayey – sandy,deep valleys with high layers of flooding and plains of flooding. The mentioned zones are shown in theobtained map.Based on the observations made in each of the zones, it can be concluded that the instability of the rockmassifs in the different points of the city is due mostly to the geomorphologic processes, for that reason ahistorical reconstruction of the stated processes for recent period is highly recommended PB Sociedad Geológica de España YR 2005 FD 2005 LK http://hdl.handle.net/10272/8649 UL http://hdl.handle.net/10272/8649 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 31 may 2026
