The conference South America Water from Space IV will focus on the latest scientific advances and state-of-the-art instruments and methodologies developed to characterize global water cycle variability and to identify the primary needs in modeling and data assimilation to improve our knowledge of the water cycle and our ability to quantify its future changes. WE welcome work focusing on the applications of remote sensing to investigate water management issues, liquid and solid discharge in rivers, hydrometeorological risks, precipitation and cryosphere, water levels and surface waters, lakes, rivers and wetland, evapotranspiration and soil moisture, irrigation, floods and droughts, modeling the water cycle, among others. Special contributions dealing with South American regional thematic (rivers such as the Amazon, the Orinoco, La Plata, arid areas etc..) are a plus, but contributions dealing with tropical large river basins in general are most welcome.

One part of the conference will be devoted specifically to the new capabilities and new results of the SWOT mission, along with the possibilities provided by the current satellites of the European COPERNICUS space program. Thus, we encourage presentations that show the benefits of high spatial resolution observations of freshwater, and that could serve as a basis for discussions by European and South American research teams and operational institutes of the capabilities offered by future SWOT satellite observations. The conference, through very rich presentation and poster sessions and courses and training will also, and it is our priority, provide an opportunity for students and young scientists (with special attention to gender equality) to be trained by renowned scientists in technical and scientific activities.
