Towards a systemic assessment of environmental impact (SAEI) regarding alternative hydrosedimentological management practice in the Canal del Dique, Colombia

Ingeniería e Investigación, 2013
The Canal del Dique, located on the Colombian Caribbean Coast, can be seen as an "artificial" branch of the River Magdalena. Since its inception in 1650, it has undergone a series of interventions aimed at optimising river navigation between Cartagena ...

Hydrosedimentological modeling in a headwater basin in Southeast Brazil [PDF]

Revista Brasileira de Ciência do Solo, 2020
Hydrosedimentological modeling is a useful tool to predict the water dynamic in a basin and for water resources management. This study aimed to i) evaluate the ability of Soil and Water Assessment Tool (SWAT) to model sediment load and continuous monthly

Vulnerability of the biota in riverine and seasonally flooded habitats to damming of Amazonian rivers

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 31, Issue 5, Page 1136-1149, May 2021., 2021
Abstract The extent and intensity of impacts of multiple new dams in the Amazon basin on specific biological groups are potentially large, but still uncertain and need to be better understood. It is known that river disruption and regulation by dams may affect sediment supplies, river channel migration, floodplain dynamics, and, as a major adverse ...

Understanding the Environmental Impact of a Mine Dam Rupture in Brazil: Prospects for Remediation

Journal of Environmental Quality, Volume 48, Issue 2, Page 439-449, March-April 2019., 2019
The rupture of the Fundão mine dam in Mariana municipality, Minas Gerais State, Brazil, spilled the tailings across the Doce River basin. These tailings, composed of residues discarded from the beneficiation of iron ore, are rich in SiO2 and Al2O3, as well as some ether amine compounds and NaOH.

Nonlinear Responses Between Watershed Hydrological Functional Connectivity and Rainfall‐Runoff‐Sediment

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Hydrological connectivity plays a critical role in influencing the runoff‐sediment process within watershed, while its behavior under varying rainfall conditions remains unclear. In this study, total 221 rainfall events were classified into three types: I (long‐duration light rainfall), II (short‐duration storm rainfall), and III (long ...
