Disastrous Flash Floods Triggered by Moderate to Minor Rainfall Events. Recent Cases in Coastal Benguela (Angola)

Autor: Pedro A. Dinis, João Huvi, Marina Cabral Pinto, Joel Carvalho

Publikováno v: Hydrology, Vol 8, Iss 2, p 73 (2021)

The present work focuses on two recent flash floods in coastal Benguela (Angola), both triggered by moderate rainfall but which had disastrous consequences for local populations (namely 71 deaths in 2015 and 17 in 2019). The research involved a regio

Estratigrafia do delta do Catumbela. Controlos sobre a sedimentação e consequências para a ocupação histórica do litoral de Benguela (SW de Angola)

Autor: João Huvi, J. M. M. Azevedo, Pedro Dinis

Publikováno v: Estudos do Quaternário / Quaternary Studies. :1-14

O delta do Catumbela é uma importante acumulação sedimentar no litoral SW de Angola. Neste trabalho apresenta-se a estratigrafia da acumulação sub-aérea e uma análise dos processos responsáveis pela sua evolução morfo-sedimentar. O trabalho

The Catumbela delta (SW Angola). Processes determining a history of changing asymmetry

Autor: Pedro Dinis, Pedro M. Callapez, João Huvi

Publikováno v: Journal of African Earth Sciences. 145:68-79

It is presented an investigation on the morpho-sedimentary evolution of one of the largest sub-aerial delta protrusions in west Africa: the Catumbela delta. The planform geometry of this delta is characteristic of an asymmetric wave-dominated accumul

Sedimentary processes controlling ultralong cells of littoral transport: Placer formation and termination of the Orange sand highway in southern Angola

Autor: João Huvi, Pieter Vermeesch, Mara Limonta, Sergio Andò, Marta Padoan, Eduardo Garzanti, Annette Hahn, Pedro Dinis, Giovanni Vezzoli, Alberto Resentini, Martin Rittner

This study focuses on the causes, modalities and obstacles of sediment transfer in the longest cell of littoral sand drift documented on Earth so far. Sand derived from the Orange River is dragged by swell waves and persistent southerly winds to accu

Dynamic uplift, recycling, and climate control on the petrology of passive-margin sand (Angola)

Autor: Eduardo Garzanti, João Huvi, Sergio Andò, Marta Padoan, Alberto Resentini, Annette Hahn, Martin Rittner, Mara Limonta, Giovanni Vezzoli, Pieter Vermeesch, Pedro Dinis

The subequatorial Angolan continental margin offers excellent conditions to test textbook theories on the composition of passive-margin sediments generated in different climatic and tectonic regimes. We use here comprehensive petrographic, heavy-mine

Climatic zonation and weathering control on sediment composition (Angola)

Autor: Pieter Vermeesch, João Huvi, Pedro Dinis, Eduardo Garzanti

Complementary mineralogical and geochemical datasets on fluvial, beach and dune samples collected along the Atlantic margin of subequatorial southwestern Africa are used to investigate the relationships between provenance and climatic controls on sed

Sand spits are important coastline features in western Angola, but only limited knowledge on their recent evolution and sediment sources were obtained so far. The present study is focused on the Baia Farta and Lobito sand spits of coastal Benguela th
