Presentation
Coastal erosion on the sandy coastline of Chile constitutes a problem due to natural phenomena and has turned worse by anthropic actions. We studied 22 beaches with more than 120 satellite images of 30 m (Landsat 5, 7 and 8) and 20 m (Sentinel 2) spatial resolution, between 1984 to 2021, to correlate the interannual shoreline changes deduced from s...

Los ecosistemas andinos de Chile central son una de las zonas más vulnerables al cambio climático a nivel mundial. Además, estos ecosistemas históricamente han sido usados por las comunidades locales para realizar ganadería trashumante en verano (veranadas). Sin embargo, los impactos de las veranadas en los ecosistemas de montaña, en un contexto de...

Climate Change is affecting the precipitation patterns worldwide and especially in mountain areas and therefore changing the occurrence of rainfall-induced landslides. This chapter assesses the estimated effects and extension of landslides in Climate Change scenarios in the Andes of Central Chile, showing that despite the projected overall decrease...

Las áreas costeras de la región de Valparaíso de Chile por sus características oceanográficas, climáticas y ecológicasson de gran importancia para el desarrollo turístico, económico y ambiental del país. Las costas de la región se han vistoafectadas por eventos extremos desde 2015, con marejadas recurrentes que han aumentado respecto a años anterio...

Restricted episodic changes occurred in a short time period and over large spatial extents. Extreme weather conditions usually give rise to restricted episodic changes. Sentinel-1 radar images of the Salar de Aguas Calientes in Chile acquired in the Altiplanic winter (March 2015 and June 2017), 2018 austral winter and 2017–2018 springtime, demonstr...

A dense time series of Synthetic Aperture Radar acquisitions at 6-day intervals between July 2017 to January 2019 collected with the C-band constellation Sentinel 1A and 1B is used to study salt crust evolution in an highland salar. Microwave response of halite crystal aggregates is linked to surface roughness of the salt crusts by means of a surfa...

Seasonal changes control the development of salt crust over the Salar de Aguas Calientes Sur located in Andes Highlands, Chile. Precipitations throughout the Altiplanic winter (December to March) and austral winter (June to September) caused ponds to enlarge and surface salt crusts to dissolve driving roughness and dielectric features of the salar...

p>Predicting the potential distribution of short-lived species with a narrow natural distribution range is a difficult task, especially when there is limited field data. The possible distribution of L. ovallei was modeled using the maximum entropy approach. This species has a very restricted distribution along the hyperarid coastal desert in northe...

The upper section of the Mapocho river basin is in constant danger of landslides. This study had the objective of zoning the upper Mapocho river basin for the susceptibility of landslides using hydrological, geological, and geomorphological data. Areas with a high degree of landslide susceptibility are located on the lower part of the main valleys...

p>Trophic structure deterioration in continental water bodies (lakes and damps) has been a growing problem during the last years. Numerous factors, either natural or man-made contribute in value increments of various water quality indexes ranging toward eutrophication. Our study had objective to use remote sensing as complementary tool to study the...

In September 2005, by first time in the city of Cordoba, Argentina, it was carried out a meeting with researchers representing countries of all the continental America, plus some from Italy and Spain. All of them, including us, were dedicated to the use of outer space technologies for peace, mainly we referred it as geomantic tools, like remote sen...

En la actualidad, frente a la alteración de los patrones de variabilidad y el Cambio Climático, está teniendo relevancia el conocimiento de las dinámicas de los sistemas naturales, especialmente de los sistemas lagunares costeros, a fin de poder constatar, si estas dinámicas están siendo afectadas por dichas alteraciones climáticas.

Utilizar información satelital que disponen las plataformas Landsat (5, 7 y 8), Sentinel 2, para caracterizar la evolución de la línea de costa chilena y deducir información clave para caracterizar la movilidad de las playas a distintas escalas temporales: a corto, medio y largo plazo. Ello permitirá tomar las decisiones correctas para hacer frente a los impactos del cambio climático y lograr una gestión sostenible de las playas.
