Modelling Rivers


Rivers are natural water courses. They have vital contributions to the social and economical welfare of societies living along their course. They provide continuous, usually dependable, flow and supply of water. Accordingly, centralised civilisation began emerging independently along number of river valleys; e.g. the Nile, Tigris and Euphrates, the Indus and the Yellow Rivers. Since then, mankind has been in continuous struggle to understand and live in harmony with this gift/force of nature. Modelling rivers is the modern way to understand their behaviour and is an essential tool to tackle several river problems.

Delft3D is the state-of-the-art modelling framework for hydrodynamics, water quality, ecology, waves and morphology.
Here, in this space, we share knowledge & experiences, and discuss issues related to modelling of rivers.

modeling the salt-fresh water balance at sluices?

Hi all,

I'm new to this community and don't know my way around (yet). Could somebody direct me to where I can find out what exactly Delft 3D can do? There must be a list I guess..

More in specific, can I use Delft3d to model the salt/fresh water balance at sluices?

Thank you,

Hi Koen,

A brief overview of application areas of Delft3D-FLOW is given in Chapter 2 and Section 9.2 of the manual.

Concerning "the salt/fresh water balance at sluices" I would say probably Yes, but it depends on what kind of details you want to study. Delft3D is suitable if you're thinking about medium to large scale modeling where the sluice is one effect in a larger area that you want to model, i.e. if you're not interested in the near field 3d flow near/in the sluice. If you want to study the details of the 3d flow near/in the sluice, then you'll most likely need a non-hydrostatic solver which is in the code but still in development (see a list of ongoing developments). For this type of application, Delft3D might be suitable or maybe not. If the local geometry becomes more 3d, e.g. overhanging constructions such as a horizontal plate mid flow or closed conduits, then Delft3D is not suitable if you are interested in the flow close to those details.
