Abstract:

This dataset consists of groundwater levels measured within wells distributed across Watershed 3 at Hubbard Brook Experimental Forest from 2007-2020. Water levels are expressed as a depth (cm) from the soil surface.

This dataset is a part of a larger project aimed at explaining the spatial and temporal variation in stream water chemistry at the headwater catchment scale using a framework based on the combined study of hydrology and soil development – hydropedology. The project will demonstrate how hydrology strongly influences soil development and soil chemistry, and in turn, controls stream water quality in headwater catchments. Understanding the linkages between hydrology and soil development can provide valuable information for managing forests and stream water quality. Feedbacks between soils and hydrology that lead to predictable landscape patterns of soil chemistry have implications for understanding spatial gradients in site productivity and suitability for species with differing habitat requirements or chemical sensitivity. Tools are needed that identify and predict these gradients that can ultimately provide guidance for land management and silvicultural decision making. Better integration between soil science, hydrology, and biogeochemistry will provide the conceptual leap needed by the hydrologic community to be able to better predict and explain temporal and spatial variability of stream water quality and understand water sources contributing to streamflow.

These data were gathered as part of the Hubbard Brook Ecosystem Study (HBES). The HBES is a collaborative effort at the Hubbard Brook Experimental Forest, which is operated and maintained by the USDA Forest Service, Northern Research Station.

Description:

SAMPLING DESIGN

This network of wells was designed to monitor water table dynamics across different soil units throughout Watershed 3. At each well, a small soil pit was hand excavated to ~10 cm into the C horizon (40 to 100 cm; 65 cm average) or to the B-C horizon interface, and pedogenic horizons were described. Each soil profile was assigned a soil type based on horizon presence and thickness. Wells were constructed of standard dimension ratio (SDR) 21 or Schedule 40 PVC pipe with a 4.2-5.1 cm outer diameter with a screen consisting of 0.025 cm width lateral slots with 0.32 cm spacing between slots. Wells were either installed with a 10 cm hand auger immediately upslope of the characterization pit or in the backfilled pit. Wells were installed on top of bedrock in the cases where a C was not present. Local washed sand or native soil was used to backfill to a depth just above the screened interval, and then native soil was backfilled and carefully compacted above the screened interval to the soil surface.

DATA COLLECTION PROCEDURES

Each well had either an Odyssey Water Level Logger that used capacitance measured along a Teflon coated wire suspended in the well to determine water level recorded or equipped with a HOBO Onset U20/U20L along a nylon string where raw pressure data was corrected for atmospheric pressure by using barometric pressure data from a pressure transducer suspended in a dry well. All data was recorded at 10-minute intervals.

CALCULATIONS

To get depth of water table below the surface, substract the Pipe Height from the location and pipe height dataset. Readings that were not due to natural variations in water table were removed from the data record. For example: If a well was pumped for a sample, the water table recordings while the well recovered were removed. The other most common reason for removal was that the instrument was pulled from the well to download data, resulting in one or two data points that reflected the water level recorder being out of the well.
