Batimetría en el Río Upano tramo Tuntaime - Sera para el manejo de material pétreo, enfocado a la explotación con reposición del material en los sectores de Tuntaime y Centro Sera.

Abstract

The following investigation's objective consists to establish a precise geometric model of the river and its surroundings with the methodology of the bathymetry that make possible the calculation of flood zones and the deposition of stony materials by flood; During this process of obtaining information about the study area, the exploration stage was carried out, the fieldwork allowed to discover in the field a series of important elements, it was possible to determine through the interpretation made by perception rowing The area was recognized and the geographical location of all points of interest was recorded, as well as its relief and composition. Through the total station and the GPS delimiting the areas of interest with their respective coordinates and elevations, which are recorded a log and in turn the presentation of results on the bathymetry-topo, the local geology with calculations of probable reserves, river dynamics, drag and deposition of existing materials and types of scour, with this it was possible to propose an exploitation model according to these factors and characteristics. With the information obtained, the geometric sections are classified into isometric and asymmetric e relief of the land covered by the water. The total volume of unsorted material retained in tine dams in the Tuntaime and Sera sectors is 34099.5m3 in a continuous deposition, maintaining the extraction rate versus the replacement rate. Scour zones of two types are presented by digitizing the lateral profiles of each of the concessions, in the Tuntaime concession a normal scour is established and in the concession. Scour areas were determined in a curve.
