Tidal motion, and the seston supply to the Benthic macrofauna in the Oosterschelde

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-morphological study Douro Estuary (7) - measurements

As a continuation of the initial study on the morphology of the Douro mouth performed by Hydronamic in 1982, the Administracao dos Portos de Douro e Leixoes commissioned by Hydronamic bv to construct a mathematical hydro-morphological model of the Douro mouth. Within the framework of the study also a second measuring campaign was commissioned,...

Hydro-morphological study Tagus Estuary: Memorandum on the salinity on the inner estuary

In one of the most recent studies for AGPL, Hydronamic studied the influence of works in the outer bar on the salinity-distribution in the upstream section of the estuary. The main conclusion from this study was that current-patterns, tidal prism, etc. in the inner estuary are :fully determined by ,the geometry of the Corredor, and that...

Hydro-morphological study Douro Estuary (8); Analysis of old charts

As a continuation of the initial study on the morphology of the Douro mouth, performed by Hydronamic in 1982, the Administracao dos Portos de Douro e Leixoes commisioned Hydronamic bv to construct a mathematical hydro-morphological model of the Douro mouth. Within the framework of the study an analysis of old charts, available in the archivas of...

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, additional work

Siderurgia Nacional EP has planned to construct an ore terminal nearby Seixal (Portugal) and to dredge an access channel and turning basin in the southern part of the Tagus Inner Estuary. In the Hydronamic report, entitled Terminal do Seixal, Hydro-Morphological Study, February 1982/ P457' the hydraulical, nautical and morphological consequences...

Hydro-morphological study Tagus Estuary: Additional work salt intrusion due to dredging of Barra Sul

In case Barra Sul is dredged, there is a risk of an increased salt intrusion into the estuary. Model computations have been performed to comper present salt intrusion with future salt intrusion

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...

Hydro-morphological study, measurements and calculation expected siltation

Morphological study (measurements and computation) for a new access channel to the Quimigal productuion plant in Seixal (Lisbon) in the Tagus Estuary (Tejo). The report contains measurement data of flow and sediment concentrations on various locations in the Tagus inner estuary.
