Internship/Msc Proposal: A new approach for urban drainage design

Last updated: 13 August 2017 at 22:38

Title: ”A new approach for urban drainage design”
Supervisor: Joost Beckers (joost.beckers@deltares.nl)
Background: Stochastic hydrology
Period: 2017

Research objective: Apply a new method for design of urban drainage systems

Methodology: A new scheme for design of urban drainage has been developed by Deltares and now needs to be applied to a simple but realistic test case. The method uses Intensity-Duration-Frequency (IDF) rainfall statistics as a basis for design. In contrast to many existing methods, actual rainfall patterns that have been observed at the location of interest or from other locations can be used, in conjunction with the IDF statistics. Most existing methods either use idealised rainfall or do not comply with the IDF. The new method therefore has the potential to become an important alternative over these existing methods. You will get the opportunity to be the first to show how the method works in a real application.

The student will:
• Conduct a brief literature review of existing approaches for urban drainage design
• Setup a simple test model of an urban drainage system
• Apply the time series approach
• Apply the design event approach
• Apply the new method and compare the results to those from the other two methods

Keywords: Urban drainage, rainfall runoff, frequency analysis, hydro-informatics

Output (expected results):
The study is likely to be submitted to a peer-reviewed journal.
The requirements to the candidate are:
• Knowledge of hydrology and urban drainage
• Knowledge of statistics and probability
• Programming skills. Knowledge of Python is a plus but not essential
Background material (if any): upon request
