PhD studentship in Modelling of alluvial dunes

dprweb — Thu, 19 Apr 2012 03:25:17 +0000

The Department of Environmental Engineering at Hokkaido University invites applications for a PhD scholar in the area of computational modelling in river engineering. The successful applicant will join the research group in hydraulic engineering laboratory at Graduate School of Engineering in Hokkaido University. The hydraulic laboratory group performs research in several areas of river engineering experimentally and numerically to study the hydrodynamics and the sediment transport in the rivers and the effect of sediment transport on river morphodynamics.

There is a strong focus on Computational Fluid Dynamics (CFD), where numerical methods for flows are coupled with sediment transport model and morphodynamics. The applicant will develop a numerical model based on Cartesian grid with local refining, and apply multigrid techniques to solve two-dimensional shallow water equation coupled with sediment transport and bed morphology. By developing this model, the candidate is expected to apply the model for the simulation of morphodynamics in high waves during floods, and validate the results with the available measured data.

Applicant must hold a Master degree or equivalent in Civil Engineering, Fluid Mechanics, or other relevant area of technology and science. Applicants should have a strong background and interest in applied mathematics, fluid mechanics and numerical techniques. It is recommended that the candidate have good knowledge of turbulence modelling. Good programming skills in Fortran or C is a prerequisite. Knowledge about parallelisation is a plus.

To find out more about the Department, go to:

http://ws3-er.eng.hokudai.ac.jp/dpr/dpr_eng/?page_id=455

The applications for the position will be open until 1 September 2012 or until it is filled.

Interested candidates are invited to send an application including cover letter, CV, list of publications and two references electronically to Prof. Y. Shimizu (yasu@eng.hokudai.ac.jp), Dr. I. Kimura (i-kimu2@eng.hokudai.ac.jp), or Dr. M. Nabi (m.nabi@tudelft.nl).

PhD studentship in modelling of river banks erosion

dprweb — Thu, 19 Apr 2012 03:19:55 +0000

There is a strong focus on Computational Fluid Dynamics (CFD), where numerical methods for flows are coupled with sediment transport models and morphodynamics. The applicant will work on implementing, adjusting and testing existing models and numerical algorithms developed at the department. The ultimate goal of the project will be improvement the existing computational tools for handling with bank erosion problems, accounting the cohesiveness of sediment and block avalanching. By developing the bank erosion model, the candidate is expected to apply the model for the simulation of river meandering.

Mr. Inoue got the doctor degree today.

Congratulation!!

DPR Tube

dpr — Sun, 25 Dec 2011 02:15:08 +0000

We create the new movie garally page, which call DPR Tube.

http://ws3-er.eng.hokudai.ac.jp/dpr/dprtube/

On this page, we would like to broadcast our simulation results.

Please have a look on that.

Chao Phraya River, 2011 Flood

dpr — Fri, 04 Nov 2011 00:54:42 +0000


ThaiThis browser does not support flash! You can download the video instead.

The grate flood had occurred in Thailand in this October and November.

Iwasaki ,Doctor student, had simulated the flood at there by using following condition.

This simulation is tentative result of us.

Calculated by Toshiki Iwasaki the doctor course student using iRIC2.0.
250m x 250m computational grid.
Q = 10,000 m3/s (Constant Discharge)
Manning's roughness coefficient = 0.03

Caution!!!!

This simulation is the flood which set by upper condition.

So far we didn't compare the actual date of Chao Phraya River Flood.

We can't take any responsibility for the reproductivity of this result.

Grate flood had occurred in Mississippi River on 2011, May.

At that time floodway had executed at Kairo, Illinois.

This simulation has run by Toshiyuki Tanaka, Master course student, under the cooperation of

Jon Nelson.
