intro story DELWAQ

DELWAQ

DELWAQ is the engine of the D-Water Quality and D-Ecology programmes of the Delft3D suite. It is based on a rich library from which relevant substances and processes can be selected to quickly put water and sediment quality models together.

The processes library covers many aspects of water quality and ecology, from basic tracers, dissolved oxygen, nutrients, organic matter, inorganic suspended matter, heavy metals, bacteria and organic micro-pollutants, to complex algae and macrophyte dynamics. High performance solvers enable the simulation of long periods, often required to capture the full cycles of the processes being modelled.

The finite volume approach underlying DELWAQ allows it to be coupled to both the structured grid hydrodynamics of the current Delft3D-FLOW engine and the upcoming D-Flow Flexible Mesh engine (1D-2D-3D) of the Delft3D Flexible Mesh Suite (or even other models such as TELEMAC).

'DELWAQ in open source' is our invitation to all leading experts to collaborate in further development and research in the field of water quality, ecology and morphology using Delft3D. Feel free to post your DELWAQ related questions or comments in this dedicated forum space. If you are new to DELWAQ, the tutorial (in the user manual) is a good place to start. A list of DELWAQ related publications is available here.

Tahapan pertama adalah dengan mempersiapkan gambar perencanaan dan melakukan survey lokasi,  dimana output yang dihasilkan adalah ukuran awal. Terdapat dua pengukuran, yaitu pengukuran longitudinal (untuk mencari trase saluran dan batas pembebasan) dan pengukuran cross section (untuk mencari elevasi saluran). Survey lokasi diperlukan untuk mengetahui apakah pada area kerja terdapat harga tutup u-ditch saluran lain dengan fungsi sejenis. Atau saluran lain dengan fungsi berbeda sehingga dapat dilakukan pengaturan berupa saluran bersusun.

Returning to the universe of her bestselling Imperial Radch trilogy, Ann Leckie shifts her storytelling vista from a galactic scale to an individual’s journey to find their place on the grand stage. Leckie’s use of alternative pronouns for gender (“super mario bros”, in addition to “he” and “she”) creates an honest space for characters to reveal who they are, unburdened by preconceptions of identity. Leckie’s rendering of Ingray is especially compelling—riddled with misjudgments and tearful vulnerability, she nevertheless embarks on criminal actions, sparking an planetary crisis in the process.
