Data Acquisition, Preprocessing and Modelling using HEC-RAS

Training on Data Acquisition, Preprocessing and Modelling using HEC-RAS
18-29 September 2017

Follow lectures on the theory for hydraulic modelling with HEC-RAS and acquire practical experience during computer exercises on hydraulic modelling with HEC-RAS.

For whom?
The course is designed for professionals (engineers and scientists) active in the water sector, especially those involved in using simulation models for water management.

Learning objectives

  • Find and analyse freely available GIS and Remote Sensing datasets
  • Preprocess data (GIS, remote sensing, tabular data) for use in models (e.g. conversion, projection, catchment delineation, etc.) using open source software (QGIS, GDAL)
  • Use scripts (Python) to batch process datasets
  • Implement HEC-RAS for hydraulic modelling

For many studies models are used or developed. During modelling courses not much attention is paid to the preprocessing of input data and parameters needed for the models. A lot of open source software is available for this purpose. Besides desktop tools with graphical user interfaces, scripting is very useful for processing large datasets and timeseries. With the skills learned in the first week of this course you will be able to find open access GIS data and more efficiently process your data for your models using tools like QGIS, GDAL and Python. In the second week you will acquire practical experience during computer exercises on hydraulic modelling with HEC-RAS. HEC-RAS is a software program that models hydrodynamics of flow in a river and/or channel. It is used to determine if for a given discharge the flow exceeds the river bank levels. Flooding studies can be carried out to determine the flood extent and volume.

Prerequisites
It is expected that participants have good computer skills and basic knowledge of hydraulics.

UNESCO-IHE conducts a wide range of short, intensive and highly specialized courses which are aimed at upgrading and refreshing the knowledge and skills of mid-career professional and senior experts.

Short courses are meant for professionals – or groups of professionals – with a specific area of interest and a limited amount of time. The focus and content of short courses vary from specialised and technical matters to challenges and approaches in management. Didactical methods used in these short courses include lectures, individual or group exercises in the classroom, behind the computer, or in the laboratory.

Fieldwork, excursions and field visits to relevant sites often are a part of a short course, allowing the participants to come into contact with practical examples of the theory offered. Through case studies, role-plays and workshops, content is made more interactive, and experience that the participants already have is shared.

Admission Criteria
You should at least have a Bachelor Degree in a relevant field of study, some years of working experience and a good command of the English language.

NFP, MSP and SIDS Fellowships
Most of our short courses are eligible for NFP, MSP and SIDS Fellowships. Candidates from eligible countries are always encouraged to apply for one. 


You will need to have academic admission at UNESCO-IHE before you apply for an fellowship. Please be aware that the UNESCO-IHE application deadline and the fellowship application deadlines are different.


You may register by filling out the online application form available at the webpage of the Short Course of your preference. Within 15 working days you will be notified about the outcome of your application. You will receive more details about how to apply for the fellowship when you are academically admitted. In case you would like to be nominated for a NFP/MSP fellowship
