IGCP 565 Workshop 3: Separating Hydrological and Tectonic Signals in Geodetic Observations Reno, Nevada, October 11-13, 2010

Welcome to the Web Page of the Third IGCP 565 Workshop

The Third Workshop in the sequence of five annual workshops organized by the IGCP 565 Project was held on October 11-13, 2010 in Reno, Nevada, USA. This workshop was jointly organized by the IGCP 565 Project, the Group on Earth Observations (GEO), the Global Geodetic Observing System (GGOS), and the Nevada Bureau of Mines and Geology (NBMG) and the Nevada Geodetic Laboratory (NGL) at the University of Nevada, Reno (UNR).

The Workshop venue was the campus of the University of Nevada, Reno (UNR). UNR has recently opened the Joe Crowley Student Union, which provided excellent facilities ensuring a very effective and pleasant workshop.

The focus of this workshop was on the separation of hydrological and tectonic signals in geodetic observations of time variable Earth's gravity field, surface displacements, and rotation. In regions like the Southwestern U.S., the Mediterranean, Northern India, East Africa, and large parts of East Asia, tectonic processes and changes in land water storage produce overlapping signals in geodetic observations. At the same time, these regions experience water scarcity and would benefit from improved water management informed by improved data on water storage changes. In order to fully utilize the potential of geodetic observations to provide estimates of land water storage changes in these regions, the tectonic and hydrological signals need to be separated.

The Workshop brought together experts in the relevant fields including geodesy, tectonics, and hydrology for a review of the current state of knowledge with respect to the geodetic fingerprints of the tectonic and hydrological processes. It was the goal to identify the main challenges in modeling and separating the various contributions, and to make progress towards an agenda to address these challenges through focused research projects.
