We present a new hydrometric dataset that comprises water level and discharge time series measured at five tributaries draining sub-catchments of the mountainous Mueglitz River Basin in Germany. The monitoring sites were set up as far downstream as possible, taking into account technical and access restrictions. In total, 746211 records of absolute...

... the past, the region was often affected by extreme precipitation events which in combination with the catchment properties and missing natural and artificial retention areas lead to severe flash floods, resulting in severe damage. Automatic dataloggers were installed near the outflow of 5 tributaries which drain parts of a plateau area in the central part of the basin ( Fig. 4 ). The exact locations and catchment areas are listed in Table 2 . ...

... Level-Temperature-Conductivity (LTC) data loggers (Solinst Canada Ltd., Georgetown, ON, Canada, Toran 2016) are small waterproof devices recording water level, temperature, and conductivity with 5-min temporal resolution (Hannemann et al 2022). These low-cost loggers have been installed to monitor the surface water dynamics in 5 small streams that drain sub-catchments around the main site, close to their confluence with a higher order stream (Fig. 3). ...
Heavy Precipitation Events (HPE) are the result of enormous quantities of water vapor being transported to a limited area. HPE rainfall rates and volumes cannot be fully stored on and below the land surface, often leading to floods with short forecast lead times that may cause damage to humans, properties, and infrastructure. Toward an improved scientific understanding of the entire process chain from HPE formation to flooding at the catchment scale, we propose an elaborated event-triggered observation concept. It combines flexible mobile observing systems out of the fields of meteorology, hydrology and geophysics with stationary networks to capture atmospheric transport processes, heterogeneous precipitation patterns, land surface and subsurface storage processes, and runoff dynamics. As part of the Helmholtz Research Infrastructure MOSES (Modular Observation Solutions for Earth Systems), the effectiveness of our observation strategy is illustrated by its initial implementation in the Mueglitz river basin (210 km²), a headwater catchment of the Elbe in the Eastern Ore Mountains with historical and recent extreme flood events. Punctual radiosonde observations combined with continuous microwave radiometer measurements and back trajectory calculations deliver information about the moisture sources, and initiation and development of HPE. X-band radar observations calibrated by ground-based disdrometers and rain gauges deliver precipitation information with high spatial resolution. Runoff measurements in small sub-catchments complement the discharge time series of the operational network of gauging stations. Closing the catchment water balance at the HPE scale, however, is still challenging. While evapotranspiration is of less importance when studying short-term convective HPE, information on the spatial distribution and on temporal variations of soil moisture and total water storage by stationary and roving cosmic ray measurements and by hybrid terrestrial gravimetry offer prospects for improved quantification of the storage term of the water balance equation. Overall, the cross-disciplinary observation strategy presented here opens up new ways toward an integrative and scale-bridging understanding of event dynamics.
