Luctor et Emergo, het sluiten van de dijksgaten van Walcheren

In 1944 because of the allied bombing of the island of Walcheren a number of dikes had breached and the island was flooded. The four breaches (Westkappelle, Nolle, Veere and Rammekens) were closed in 1944 and 1945 with a lot of improvisation. Also some caissons (phoenix caissons from the Mulberry harbours from the Normandy landings) were applied...

Morfologische ontwikkeling van de Westerschelde sinds 1650

In het kader van een afstudeerproject is een studie verricht naar de morfologische ontwikkeling van de Westerschelde sinds 1650 volgens eendimensionale rekenmodellen. De validatie van dit soort modellen is namelijk een probleem. Van de Westerschelde bestaat weliswaar een groot aantal meerdimensionale modellen, maar door de grote hoeveelheid aan...

Het verjaagde water, de getijbeweging op Walcheren en de caissonsluitingen in 1945/1946

Because of the allied bombing of Walcheren in 1944 the island suffered from a number of breaches. These breaches were closed in the period 1944-1945. The closures have been described by A. den Doolaard in his novel "Het Verjaagde Water". For the closure Phoenix caissons have been used from the Mulberry harbours build during the allied landings...

DUFLOW manual

Manual for the program DUFLOW, a micro-computer package for the simulation of one-dimensional unsteady flow and water quality in open channel systems. Duflow is a one-dimensional network programme. The model can be used for irrigation and drainage networks, for tidal flow in estuaries, and may include water quality parameters.

ECDUFLOW: Evaluation Check DUFLOW: Research concerning PC-program ECDUFLOW

Using the micro-computer package DUFLOW for the simu1ation of onedimensiona1 unsteady flow in channe1 systems (Ref. [1]) it is very important to check the resu1ts of the very first ca1cu1ation for a new cana1 system. The first MODEL of a new network system wi11 contain one or more mistakes concerning the cross-sections, the storage area or the...

DUFLOW Simulations 1: Tidal Propagation in Networks

To illustrate the operational use of the micro-computer package DUFLOW for the simulation of one-dimensional unsteady flow in channel systems the tidal propagation in an irrigation system (IRRSYS) is considered. The propagation of periodical shallow water waves in a network system (tidal waves in river systems, estuaries, etc. and also harbor...
