The water cycle from space: the central role of satellite-informed models in corporate water management

Water in the atmosphere, in the soil, in rivers and oceans is in continuous exchange via the global water cycle. This is commonly thought to be the circular movement of water that evaporates from the Earth's surface, rises on warm updrafts into the atmosphere, and condenses into clouds. It is transported by the wind as water vapour, and eventually falls back to the Earth’s surface as rain or snow.

Interview with Arjen Haag, Researcher and Consultant in hydrology and water management at Deltares

Arjen Haag is a hydrologist and remote sensing analyst working at the Operational Water Management & Early Warning department of Deltares. We talk to him about the role that earth observation plays in his projects, SERVIR-Mekong, his experiences in the space and water sector and his vision for innovation in the remote sensing community. We ask him about challenges related to flood mapping and forecasting, whether water data should be shared openly and the transfer of knowledge to those needing it the most. He shares his insights on the use of satellite data, algorithms and models, as well as artificial intelligence and machine learning. And finally, why sandcastles were important for all of this.

Interview with Benjamin Kitambo, PhD student at the Laboratory for Space Geophysics and Oceanography

Describe your professional (and/or personal) experience relating to water and space technologies.

My interest in water is a result of my background in Geology. I come from a region (Katanga Province, Congo DR) where mining is the main source of livelihood. So, I had my bachelor's degree in Geology intending to work in the mining sector after graduation. However, towards the end of the bachelor’s programme, I was exposed to the deployment of geophysical equipment for water prospecting in my department.

Introduction to Modflow and Model Use Capacity Building and Training Material

Introduction to Modflow and Model Use

This course provides basic knowledge about MODFLOW and Model Muse, which can be used to develop, run, and post-process models. MODFLOW in Model Muse combines many of the capabilities found in MODFLOW 6, MODFLOW-2005, MODFLOW-NWT, MODFLOW-USG, and MODFLOW-LGR, and provides a platform for adding packages.
