The CEH-led SUNRISE programme, which focuses on parts of Asia and sub-Saharan Africa, is delivering scientific evidence and advice that will improve people’s livelihoods, health and well-being. Through SUNRISE we provide capacity-building and training that will help national and local stakeholders.
As part of our SUNRISE activities, Lisa Stewart, Adam Griffin, Harry Dixon, Lucy Barker and Simon Parry from the Centre for Ecology & Hydrology recently organised a workshop on flood and drought estimation in Mumbai involving stakeholders from across India with the aim of building new links and identifying key areas for action. Adam Griffin tells us more…
We held a three-day workshop on Improving Flood and Drought Estimation and Prediction in Data Sparse Regions at IIT Bombay from 26-28 November 2018, co-convened by CEH with Professor Arpita Mondal and the Maharashtra Engineering Research Institute.
Flood and drought hazards
The Indian monsoon season is crucial to many aspects of agriculture and the economy in much of peninsular India. But Mumbai has been hit by several large floods in the last 15 years. Conversely, nearly half of the administrative districts in Maharashtra State declared a drought in 2018, with a similar situation occurring only two years previously. The worst drought in 40 years occurred in 2013.
We believe that the ability to monitor and estimate the severity and frequency of floods and droughts is vital for adequately designing infrastructure and developing management plans to mitigate their impacts. Research to better understand flood and drought hazards and to develop tools for improved monitoring is crucial to improve and inform such projects and procedures.
The workshop held in November 2018 brought together a wide range of academic, industrial and governmental stakeholders to discuss the current issues in flood and drought estimation, prediction and monitoring in India, and more specifically in the state of Maharashtra. It focused on the following questions:
- What methods are currently being used in flood frequency estimation and drought monitoring?
- What information do practitioners and policy makers need? Who are these key practitioners, and how can they be engaged?
- What are key drought indicators and impacts needed to better understand and monitor droughts?
- How can research and practice work together more closely in identifying issues for research and development?
- How are climate and anthropogenic change affecting floods and droughts in the region? What will the needs of the future be like?
CEH scientists are taking part in a Flood & Drought #risk estimation workshop at @iitbombay India this week, part of the #SUNRISE_science programme.

The workshop featured presentations from prominent academics and stakeholders in the field, and from members of the organising institutes. Speakers introduced state-of-the-art research from both the UK and India, including details of India’s first real-time integrated flood forecasting system in Chennai, as well as current practices and future needs for flood and drought management.

Meanwhile the importance of non-stationarity in flood risk estimation was highlighted in talks by Prof Arpita Mondal of IIT Bombay and myself, when I spoke about the peak flow data held by the UK National River Flow Archive.

Besides formal presentations, fruitful discussion sessions allowed delegates from both countries to share thoughts and knowledge directly. See the agenda below for more details of sessions over the three days.
The workshop will enable more research and several collaboration opportunities. As part of SUNRISE, we plan to hold further events to share knowledge and develop deeper links between CEH and Indian researchers on these topics.
In particular, the issue of interacting directly with farmers in measuring indicators and communicating drought predictions is one of specific interest. Another key observation was that hydrological models can be restricted by the poor performance of meteorological modelling of the monsoon season, which makes flood prediction difficult.
