• Sediment Sources, Sediment Transfer in a Small Lesotho Catchment — A Pilot Study of the Spatial Distribution of Erosion Features and their Variation with Time and Climate (1985) · South African Geographical Journal · doi

  Lacking data on fluvial transport makes it difficult to estimate sediment production from certain areas. The measured reservoir sedimentation cannot directly be used as a measure of the sediment yield from the basin. The study lacks data on sediment concentrations and run-off.

• A multi-model framework for bedload sediment transport and model selection in hydraulic crossing design: application to the El Bahja River (Al Haouz region, Morocco) (2026) · Euro-Mediterranean Journal for Environmental Integration · doi

  This study adds to the scientific validation of sediment transport equations beyond their regional significance. It validates their suitability for use in flood-prone areas world- wide. The results highlight the crucial role of recalibration in improving hydraulic infrastructure design in semi-arid environments and enhancing prediction reliability.

• Suspended sediment dynamics during flash floods in two contrasting headwater catchments of the Central High Atlas (Morocco) (2026) · Environmental Monitoring and Assessment · doi

  The study identifies a research gap in the limited understanding of sediment transport processes in semi-arid environments, where sediment transport is highly episodic and closely linked to short duration, high-intensity rainfall events. The research gap also lies in the lack of understanding of the role of sediment availability and local remobilization processes in determining sediment concentration.

  Future research should focus on understanding the role of sediment availability and local remobilization processes in determining sediment concentration. Further studies should investigate the impact of rainfall forcing on sediment transport in semi-arid environments. The research suggests that future studies should consider the use of more advanced measurement techniques, such as acoustic Doppler velocimetry, to improve sediment flux estimates.
