Morphology of the mouth of the river Douro (Portugal)

The river Douro debouches into the Atlantic Ocean near Oporto (Portugal) with a funnel-shaped mouth, partly closed from the ocean with a sand spit. Both the wave-induced longshore sediment transport as the sediment yield of the river are limited by the available quantity of sediment (non-alluvial conditions). The results of some sediment...

Hydro-morphogical study Douro Estuary

The Administracao dos Portos do Douro e Leixoes is confronted with the fact that future expansion of the port area of Leixoes is limited by the surrounding hills and urbanization. One of the alternatives for future expansion might be the creation of port facilities in the Douro estuary, where a relatively large, flat area is available. However,...

Terminal do Seixal: Hydro-morphological study, additional work

Addtional drawings for the mathematical model of the estimated siltation in the access channel to Siderurgia nacional in Seixal (Lisbon).

Hydromorphological study Tagus Estuary, wave penetration model and estuarine flow model

Integrated study on the hydro-morphology of the Tagus outer estuary and the Tagus Inner estuary. Wave penetration calculations, tidal flow calculations and calibration measurements.

Terminal do Seixal: Hydro-morphological study

The calculations of bottom changes presented in our report "Terminal do Seixal Hydro-morphological study", February 1982 were based on a calibrated sediment transport formula. This formula was calibrated with the results of measurements made by Hydronamic in September 1981. These measurements were executed during one of the driest summers...

Terminal do Seixal, hydro-morphological study

Hydronamic has performed a study for the design of the new access channel to the terminal of Siderurgia Nacional at Seixal (near Lisbon) in the Tagus estuary. The report deals with the following subjects: - In chapter 2 a description is given of the mathematical tidal model, the calibration thereof and the final results. - Chapter 3 deals with...
