Historical records of the deposition fluxes polycyclic aromatic hydrocarbons (PAH) in 10 remote high altitude lakes distributed throughout Europe have been studied. Cores from each site were dated radiometrically, and results used for reconstruction pollutant changes between 1830 present. In general, both PAH pyrolytic concentrations (Σ = 23 compounds) increased uniform background levels (5−30 μg m-2 yr-1, 20−100 ng g-1 dw, respectively) at turn century to maximum values 1960−1980. After...
Urban flooding is an increasing problem in developing countries, thus understanding flood dynamics necessary to establish guidelines on urban development and management. This paper studied the lower reaches of Andalien River basin, situated coast Greater Concepcion Metropolitan Area (CMA), second most urbanized area Chile. basin experienced a record 21 events last 50 years. Patterns evolution growth were evaluated using historical analysis (1943–2011) that specifically focused how these...
This study investigates the Holocene evolution of Laraquete-Carampangue strandplain (LCS) on tectonically active coast south-central Chile using Ground Penetrating Radar (GPR) and LiDAR data. (LCS), Chile, is a rare accretionary feature in region dominated by rocky shorelines limited sediment supply. LiDAR-derived digital elevation model reveals complex geomorphology comprising 52 beach ridges, aeolian dunes, fluvial paleochannels, while GPR radargrams uncover marine facies influenced past...
Coastal erosion in 45 sandy beaches covering nearly 2000 km along the tectonically active Chilean coast is assessed during last four decades. The historical analysis based on assessment of decadal changes shoreline position extracted from topographic surveys, aerial photographs, satellite images and survey maps using DSAS software. Results show that 80% sites presented rates (>−0.2 m/y), 7% accreted (>0.2 m/y) while 13% remained stable. Eroded include headland bay beaches, embayed...
Sandy coastlines are very dynamic spaces affected by a variety of natural and human factors. In Central Chile, changes in oceanographic wave conditions, modes inter-annual climate variability such as El Niño Southern Oscillation (ENSO), extreme events earthquakes tsunamis condition the beach morphology. At same time, direct actions alter arrival sediments to coast their alongshore distribution. Despite relevance beaches for this coastal region interesting relationship morphology has with...
Climate change is severely altering rainfall patterns and increasing the frequency severity of wildfires, resulting in significant changes physical characteristics catchments. These changes, particularly hydrological stability characteristics, contribute to an increased occurrence hillslope hazards, including landslides, debris flows, flash floods, erosion. The dynamic interplay between climate-induced catchment drives complex multi-hazard interactions—such as cascading,...
ABSTRACT Hexachlorocyclohexanes (HCHs; α‐ and γ‐isomers), endosulfans (α‐ β‐isomers the sulfate residue), hexachlorobenzene (HCB), dichlorodiphenyltrichloroethane (DDTs), polychlorobiphenyls (PCBs) were measured in waters from three European remote mountain lakes situated Alps, Pyrenees, Caledonian mountains. Sampling encompassed both ice‐free ice‐covered periods at different water column depths. High HCH concentrations found all lakes, those Alps Pyrenees (990–2900 pg/L) being among highest...
To reduce health care costs and improve care, payers physician groups are piloting value-based episodic or bundled-care payment models in oncology. Disease progression associated may affect these models, particularly if such programs do not account for disease severity risk across patient populations. This study estimated the incremental cost of patients diagnosed with metastatic breast cancer (mBC), colorectal (mCRC) lung (mLC) compared among without progression.This was a retrospective...
La urbanización en Concepción metropolitano (36°S) las últimas décadas ha impactado áreas de valor ecológico, tales como humedales y lagunas.Aquí analizamos la perturbación parámetros biodiversidad seis urbanos, mediante exploración uso indicadores.Se proponen tres indicadores: naturalidad riqueza macrolepidópteros plantas, los que se evalúan modelos regresión múltiple.Los resultados indican con menor grado antrópica encuentran ubicados dentro una reserva protegida rodeados matriz paisaje...
Although Chile is one of the countries most exposed to natural hazards, date there no national index that shows differences in resilience levels within country. This study develops a community on scale based Baseline Resilience Community (BRIC) index. The BRIC for was built with 49 indicators, from different sources at district level. Our results determined not distributed homogeneously throughout highest are concentrated central macro-zone. In comparison, extreme zones focus close 90% their...
Economic costs associated to coastal erosion are projected in 45 sandy beaches Chilean coasts. We compare mid-century (2026–2045) and end-of-century projections (2081–2100) of wave climate sea-level rise (SLR) with a historical period (1985–2004) using several General Circulation Models for the RCP 8.5 scenario. Offshore data then downscaled each site, where shoreline retreat is assessed Bruun rule various berm heights sediment diameters. Results indicate that would be moderate (>13 m)...
