| Zusammenfassung |
| The town of Machu Picchu, Peru, serves the >700 000 tourists visiting
Machu Picchu annually. It has grown threefold in population in the past two
decades. Due to the limited low-lying ground, construction is occurring on
the unstable valley slopes. Slopes range from <10° on the valley
floor to >70° in the surrounding mountains. The town has grown on a
delta formed at the confluence of the Alcamayo, Aguas Calientes and
Vilcanota Rivers. Geohazards in and around the town of particular concern
are 1) large rocks falling onto the town and/or the rail line, 2) flash
flooding by any one of its three rivers, and 3) mudflows and landslides. A
prototype early warning system that could monitor weather, river flow and
slope stability was installed along the Aguas Calientes River in 2009. This
has a distributed modular construction allowing components to be installed,
maintained, salvaged, and repaired by local technicians. A diverse set of
candidate power, communication and sensor technologies was evaluated. Most
of the technologies had never been deployed in similar terrain, altitude or
weather. The successful deployment of the prototype proved that it is
technically feasible to develop early warning capacity in the town. |
