Impact of the 2010–2011 La Niña phenomenon in Colombia, South America: The human toll of an extreme weather event
Natalia Hoyos,Jaime Escobar,Jaime Escobar,Juan Camilo Restrepo,A.M. Arango,Juan Carlos Ortiz +5 more
TL;DR: In this article, the authors analyzed the spatial patterns of effects on the population, measured as the number of affected persons in each municipality normalized to the total municipal population for 2011, using global (Moran's I index) and local (LISA) spatial autocorrelation indicators, and multiple regression analyses (OLS and ML spatial error model).
Journal ArticleDOI
Freshwater discharge into the Caribbean Sea from the rivers of Northwestern South America (Colombia): Magnitude, variability and recent changes
Juan Camilo Restrepo,Juan Carlos Ortiz,Jorge O. Pierini,Kerstin Schrottke,Mauro Maza,Luis Daniel Otero,Julián Aguirre +6 more
TL;DR: In this paper, the authors analyzed the monthly averaged discharge data from ten rivers in northern Colombia (Caribbean alluvial plain) draining into the Caribbean Sea to quantify the magnitudes, estimate long-term trends, and evaluate the variability of discharge patterns.
Journal ArticleDOI
Suspended sediment transport in the Magdalena River (Colombia, South America): Hydrologic regime, rating parameters and effective discharge variability
TL;DR: In this article, an analysis of the regression coefficients (a, b ) for the two periods showed a decrease in b and an increase in a after 1999, which coincides with a decrease of suspended sediment transport.
Journal ArticleDOI
Sediment Transport and Geomorphological Change in a High-Discharge Tropical Delta (Magdalena River, Colombia): Insights from a Period of Intense Change and Human Intervention (1990–2010)
Juan Camilo Restrepo,Kerstin Schrottke,Camille Traini,Juan Carlos Ortiz,Andrés Orejarena,Luis Daniel Otero,Aldemar Higgins,Leonardo Marriaga +7 more
TL;DR: Restrepo et al. as mentioned in this paper analyzed stream flow, suspended sediment load (SSL), and riverbed dynamics for estimating changes in the suspended sediment transport regime as well as of erosional/depositional patterns in different zones of the delta.
