Verhagen, H.J. (author)
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...

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...

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...

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,...

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...

Man-made islands in the Mackenzie river (Canada) for oil exploitation may obstruct the free flow of ice during spring break up. These ice dams may cause considerable rise of the water level in the rivers, resulting in floods. A numerical model is presented to simulate ice dam formation an river floods.

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...

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,...

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...

Ten behoeve van een optimale keuze van een beheersstrategie voor de stormvloedkering is het nodig inzicht te hebben in het faalgedrag van glooiingen langs de Oosterscheldedijken. Hieroe zijn o.a. proeven gedaan in de Deltagoot van het WL. Deze nota analyseert de proefresultaten en vertaalt e.e.a. naar de aanwezige glooiingen langs de...

In de "leidraad voor de beoordeling van de veiligheid van duinen als waterkering" wordt aangegeven hoe aan de bij de Deltawet vastgestelde veiligheidsnormen de duinen als primaire waterkering moeten worden getoetst. De veiligheid van de Nederlandse duinenkust is op grond van de situatie in 1983 beoordeeld. Tevens is de bezwijkkans bepaald voor...
