Estudio batimétrico y de capacidad de reposición natural de material pétreo para la aplicación de un manejo de explotación en un tramo de 6 km del Río Upano.

Abstract

The proposed research consists of carrying out a bathymetric survey and the capacity for natural replacement of stony material for the application of an exploitation management plan within a 6 km section of the Upano river, located in the province of Morona Santiago, canton Morona Macas parish, La Barranca sector; a bathymetric survey was carried out in specific areas of the Upano river prior to the analysis of field information to delimit the area where the characteristics of the river guarantee correct information, to recommend a management plan for exploitation of all artisanal mining areas located at along the Upano river, to know both the volume of replacement, as well as the way of replacement of the stone materials; and a granulometric and abrasive analysis to know the characteristics that the stone materials of the Upano river present in this 6 km stretch. For the laboratory analyzes, a survey was made of the banks of the river and collected representative samples with similar dimensions, this information was useful to define and know all the technical and necessary information that allowed us to develop an exploitation plan. It is concluded that the lack of technical measures and information about the characteristics of the Upano River, such as its optimum depth of exploitation, type of material, granulometric characteristics, abrasiveness and the artisanal miners' little technical exploitation. the natural river bed. In the same way it is verified that the river replenishes a volume of material superior to the extracted one, reasonWhy it is viable to continue with these activities.
