Capacity building programme Water budgeting tool for river basins using Google earth

engine applications

Venue: National Institute of Hydrology, Roorkee, India 19 – 23 August 2019

Organisers: National Institute of Hydrology, Roorkee, India The World Bank, New Delhi, India International Water Management Institute (IWMI), Sri Lanka

Water, one of the most important natural resources, supports people’s daily life, maintains the ecosystems that people rely on, provides transportation, recreation, ecotourism, and much more. Pressures on water resources and disasters are rising primarily due to unequal distribution, urbanization, extreme and frequent drought and flooding, pollution, deforestation, and also partly due to poor knowledge about the distribution of water recourses and poor management of water resources and usage. Remote sensing provides critical data sources for mapping water resources and changes, while GIS provides the best tool for water resource and flood risk management, presentation, visualization and publication education.

The main objective of this capacity building programme is to strengthen the government agencies and related water management institutions as part of the National Hydrology Project for India is to improve the extent, quality, and accessibility of water resources information. This training course aims at presenting the open source and public domain platform capabilities for water resource and flood risk management, including: (i) pre-processing modules to facilitate the preparation of input data, (ii) modelling tools for the analysis of several processes using Python, Google Earth Engine aimed at supporting water resource management, and (iii) post-processing tools to present knowledge and advisory products for water resource and DRR application in India. The training will support participant in learning the pre-processing tool to provide the user with enhanced time-series processing capabilities and access to various open-source satellite data, learning basic scrips both in Google Earth Engine and Python for activities related to floods and drought in showcasing the application of water resource management.

The proposed capacity building activities is the follow up of the basic GEE course held in National Water Academy in Nov 2018, which will cover shorter version of the basic GEE module and two advance GEE modules related to support irrigation systems and water resources assessment including disaster risks mapping.

The training will support the participant in learning the pre-processing tool to provide the user with enhanced time-series processing capabilities and access to various open-source satellite

data, learning basic scrips both in Google Earth Engine and Python for activities related to floods and drought in showcasing the application of water resource management. Specifically, the experts will give more focus to the Google’s GEE platform to showcase large- and small-scale scientific analysis and visualization of geospatial datasets. GEE is widely used by researchers, nonprofit organizations, educators, and governmental agencies to analyze large-scale geospatial data, and is available free of cost for non-commercial users. The initial part of the training course will basically run through basic elements on data storage and developing product, organizing, and demonstrate access to a wide variety of satellite imageries and geospatial datasets to offers global-scale environmental data analysis capabilities. In addition to the tools and cloud computational powers necessary for analyzing large datasets, the GEE platform offers Application Programme Interfaces (APIs) in JavaScript and Python.

Training concept of integration various satellite data and computing platform to generate water resource application

The capacity building and knowledge products to support the experts in promoting use of earth observation data and robust cloud platform i.e. GEE to generate operational knowledge products for critical decision making process. The government agencies will be trained with the petabyte of publicly available datasets as highlighted in the below figure. Our assumption is that the participants will learn the new technology and able to generate geospatial products and can be used in development planning. In addition the GEE is expected to be used by other users namely researchers, nonprofit organizations, educators, and governmental agencies to analyze large-scale geospatial data, and is available free of cost for non-commercial users.

The assignment will have two major components: (a) Capacity building on the use of GEE in water resources, agriculture assessment and (b) develop specific knowledge products to support in irrigation and water resource monitoring and assessment as part of the National Hydrology Project to support Ministry of Water Resources, GOI.

Expected Outcomes: The participant will have greater insights on the potential of open source satellite data and its application in water resource management. Further the participant will have the ability to apply the tools namely Google Earth Engine, Python and related remote sensing software.

Note: All the participants will be provided with the tools and script to practice in their respective departments and institutions.
