An overview of hydrometeorological datasets from a small agricultural catchment (Nučice) in the Czech Republic

Abstract

We introduce the freely available web-based Water in an Agricultural Landscape-NUčice Database (WALNUD) dataset that includes both hydrological and meteorological records at the Nučice experimental catchment (0.53 km 2), which is representative of an intensively farmed landscape in the Czech Republic. The Nučice experimental catchment was established in 2011 for the observation of rainfall-runoff processes, soil erosion processes, and water balance of a cultivated landscape. The average altitude is 401 m a.s.l., the mean land slope is 3.9%, and the climate is humid continental (mean annual temperature 7.9 C, annual precipitation 630 mm). The catchment is drained by an artificially straightened stream and consists of three fields covering over 95% of the area which are managed by two different farmers. The typical crops are winter wheat, rapeseed, and alfalfa. The installed equipment includes a standard meteorological station, several rain gauges distributed across the basin, and a flume with an H-type facing that is used to monitor stream discharge, water turbidity, and basic water quality indicators. Additionally, the groundwater level and soil water content at various depths near the stream are recorded. Recently, large-scale soil moisture monitoring efforts have been introduced with the installation of two cosmic-ray neutron sensors for soil moisture monitoring. The datasets consist of observed variables (e.g. measured precipitation, air temperature, stream discharge, and soil moisture) and are available online for public use. The cross-seasonal, open access datasets at this small-scale agricultural catchment will benefit not only hydrologists but also local farmers.

Seasonal variations of vegetative indices and their correlation with evapotranspiration and soil water storage in a small agricultural catchment

“…Meteorological and soil moisture measurements at the Nučice catchment https://doi.org/10.17221/60/2023-SWR form morphology and tillage practice in each field, the topsoil characteristics in each field are similar. (Zumr et al 2015;Jeřábek et al 2017;Li et al 2021) In-situ meteorological and soil water content (SWC) monitoring Since 2021, three meteorological stations (T_ET, L_ET, E_ET) have been deployed across three fields to measure evapotranspiration, each equipped with a net radiation sensor (NR Lite2, Kipp and Zonen, Netherlands) and all the sensors needed for the BREB calculation. In addition, one station (T_ET) has a four-component radiometer SN-500 (Apogee Instruments, USA).…”

Geophysical Survey as a Tool to Reveal Subsurface Stratification at a Small Agricultural Headwater Catchment: A Case Study

“…The Czech Geological Survey classifies the whole catchment area as "Alternating sandstone and claystonepermeability low to moderate". For more information about the catchment and instrumentation at the catchment we refer to [17].…”

Assessing spatial soil moisture patterns at a small agricultural catchment

“…The bedrock is located at depths from 6 to 20 m based on geophysical monitoring. The catchment (Fig 1) is divided into 3 separate agricultural fields (1: the upper field, 2: the left field, and 3: the right field) with slightly different agricultural operations conducted during the soil moisture surveys [8,9].
