This paper analyses the research carried out in the Tiwanaku World Heritage site in Bolivia, using unmanned aerial vehicles and satellite images. The combined use of images with different scales has made it possible to locate many archaeological structures unknown to date (drainage systems, walls, circular crop marks, and a possible dock). The Sentinel‐2 images, which were processed using principal components analysis and histogram equalization, show the river beds, flood‐prone areas, and several buried drainage channels surrounding the most important structures. The archaeological evidence obtained with the digital terrain model and natural color/multispectral images enables us to contrast a new dimension of land and water uses that go beyond what was known to date. In the same way, these images enable us to understand in detail the environmental characteristics, land use, building distribution, and flood defense structures of the Tiwanaku culture throughout its history, within the context of the environmental conditions of the Bolivian altiplano. This study allowed the authors to collect new information and pose questions on the relationship of this site with water, as well as a better understanding of the extent and habitat of this historical population.

El presente documento recoge sintéticamente las principales estructuras y claves organizativas que han marcado la redacción del proyecto arqueológico de urgencia, asociado a la recuperación del sendero y conservación de la cuenca del río Sicalpa. Este afecta en buena medida a elementos arqueológicos de gran interés de la ciudad colonial antigua de Riobamba, de modo que estos forman parte esencial del propósito básico del proyecto arquitectónico.

En este trabajo analizamos cuál es el papel de los estamentos nacionales e internacionales en la gestión holística del patrimonio inmaterial, mediante la creación de mecanismos de garantía, salvaguardia y promoción de un elemento tan frágil. Sin embargo, el origen último de cualquier esfuerzo en este sentido es el acercamiento analítico a su realidad a partir de las ciencias sociales y sus paradigmas.
