12 September 2019, LGED Training room :

We live in a rapidly changing world. Managing complex adaptive systems like Deltas in this context needs continuous monitoring and evaluation (M&E) of external influences on the systems, internal changes, and impacts of different interventions. Continuous data acquisition is an essential part of these M&E activities. However, environmental data acquisition is expensive, time consuming and effortful. In many developing countries – where the drivers and systems are changing most swiftly requiring continuous data acquisition – have severe limitation in deploying formal data acquisition systems (Water quantity and quality, environmental monitoring, geophysical and geographical data, etc.). There are a number of informal, non-traditional data acquisition systems that are showing promise in augmenting the limited data of traditional monitoring networks. These include: UAV (Unmanned Aerial Vehicle) surveys, low-cost sensor networks and the approaches and techniques are collectively known as citizen-science.

 A small scale drone survey has allowed to create a centimetre level accurate digital elevation map (DEM) for this study area. The DEM was used as a basis for a 2-dimentional flood inundation model.

Citizen science allows anyone, anywhere, can participate in meaningful scientific research. (source: NOAA)

The goal of this workshop is to share practical information on such decentralized data acquisition techniques. We offer a mix of interactive presentations, discussions and hands-on training packaged into a one day training workshop. Following are the objectives of this one day workshop:
1. Discuss the broader context of M&E for adaptive delta management and how DDAT fits into that
2. Share the experiences with using UAV for geographical and object data acquisition together with hands-on
3. Explore the opportunities of using low-cost sensor networks for environmental data acquisition with case studies.
4. Share experience and expertise on citizen-science applications in relations to adaptive delta management.
5. Discover appropriate applications for these methods and technologies in the context of Bangladesh Delta Plan 2100.

Dr. Assela Pathirana – Associate Professor of integrated urban water cycle management, IHE-Delft Institute for water education.
Assela Pathirana (1969) is a Civil Engineer and hydrologist originating from Sri Lanka. He currently leads the research programme on Water Sensitive Cities of the Flood Resilience Core Group (FRG). In this context, he is engaged in multi-disciplinary research programme that involves water quantity and quality aspects, sanitation issues as well as societal and economic aspects of urban and peri-urban development.   He has published some 55 internatinoal journal publications that has been collectively cited more than 1750 times. In addition he has co-authored a book on “Impacts of Climate Change on Rainfall Extremes and Urban Drainage Systems” in 2012 (IWA publishing) and co-edited three books.
Assela is an expert on urban flood modelling and uses his experience on data acquisition related to flood hazard and risk management to contribute to this training.

Dr. Willem Veerbeek – Senior Lecturer,  IHE-Delft Institute for water education.

William Veerbeek (1970) studied architecture at the Delft University of Technology and artificial intelligence at the VU University Amsterdam. He obtained his PhD from Unesco IHE-Delft on the topic of urban growth driven future flood risk. He worked extensively in megacities like Beijing, Dhaka and Mumbai where his work focused on the development of long term urban growth projections and subsequent changes in disaster risk. Strengthening IHE’s mission in capacity development, Dr. Veerbeek has been training many cities in climate adaption, especially in Southeast Asia.

William is an expert on urban climate adaptation and has extensive experience in Bangladesh both at local and national levels dealing with the topic.
