dr.ir. R. van der Velde (Rogier)

About Me

My name is Rogier van der Velde and I am an associate professor at the Water Resources department of the Faculty of ITC (University of Twente).

I obtained my MSc degree (2004) in Hydrology from Wageningen University. In this period I started developing an expertise in SAR-based soil moisture remote sensing at the Hydrology and Remote Sensing Laboratory (HRSL) of the USDA-ARS in Beltsville, USA.

My PhD degree I received in 2010 from the University of Twente with a dissertation focused on soil moisture estimation from active microwave observations and the modelling of water and energy exchanges at the land-atmosphere interface. Soil moisture estimation at plot-scale, I applied to C- and L-band radar observations collected with a truck-mounted scatterometer deployed during a corn growth cycle. Envisat-ASAR has been used to map soil moisture at regional-scale across the Naqu river basin on the Tibetan Plateau. The modelling of water and energy exchanges at land surface I have performed in the context of the Noah land surface model applied to a site on Tibetan Plateau.

In my post-PhD years I have continued to build on earlier developed expertise. In addition, I have devoted considerable efforts to in-situ soil moisture measurements by leading the development of the Naqu and Ngari monitoring networks on the Tibetan Plateau. Since 2015 I am responsible for the management of our monitoring network in the Twente region, which was selected as core international validation site for NASA’s SMAP (Soil Moisture Active/Passive) mission.

Over the years, my research interest has grown towards the development of Earth Observation applications for Regional Water Management. Via NWO-AES funded Optimizing Water Availability with Sentinel-1 Satellites (OWAS1S) project I contributed to this topic by investigating the added value of Sentinel-1 and SMAP soil moisture estimates for region water authorities.
