The experimental catchments are field laboratories with sophisticated long-term measurements of hydrological processes. They are not only sources of data but also sources of knowledge. Understanding of hydrological systems is limited by the frequency and spatial distribution of co-located multi-parameter observations. The session will focus on the presentation and discussion of recent developments in experimental hydrology and distributed sensing techniques. Wireless distributed sensing platforms are a key technology to address the need for higher resolution data. We solicit contributions related but not limited to the following topics:
(i) Sensor network technology (network operation systems, single and multi-hop options)
(ii) Investigations related to the operational capability of wireless networks (including analysis of signal attenuation, network performance, reliability, security, efficient data propagation strategies, and network applicability) and sensors
(iii) Wireless sensor applications (e.g. calibration and validation of remote sensing data, improved characterization of hydrological fluxes, development of upscaling and downscaling techniques, irrigation systems)
(iv) Methods for the evaluation, visualisation and interpretation of distributed data sets (e.g. soil moisture, micrometeorology, groundwater)
(v) Analysis of hydrological patterns at different scales and recent ongoing measurements in the experimental river basins throughout Europe (or elsewhere)
(vi) impact of different measures on water regime in the experimental basins identified by field measurements
(vii) unusual and unexpected hydrological phenomena identified by measurements that could not be explained by existing theoretical considerations
(viii) gaps in knowledge on integrated basin responses to present and future anthropogenic and/or climate impacts
