This collection of datasets provides the water table and throughfall data from Brunei Darussalam used in the paper: Scalar simulation and parameterization of water table dynamics in tropical peatlands by Alexander R. Cobb and Charles F. Harvey (Water Resources Research 55, doi:10.1029/2019WR025411; Cobb and Harvey 2019). It additionally provides the parameters for the peat hydraulic conductivity and specific yield functions derived in the paper, and the topographic data used to calculate the two-dimensional Laplacian of the peatsurface elevation.

The flowtube described in this flowtube geometry dataset encloses the piezometers and througfall gauges. The centroid of the throughfall gauges is taken as the location of the flowtube (in the location dataset). The areas and integrated gradients provided in the flowtube geometry dataset were used to calculate the two-dimensional Laplacian of the peat surface elevation, used in Cobb and Harvey (2019).

The hydraulic conductivity knots are recorded along with their 95% confidence intervals. Details on how they were computed from the peat surface Laplacian and throughfall and water table time series are provided in Cobb and Harvey (2019).

The specific yield knots are recorded along with their 95% confidence intervals. Details on how they were computed from the peat surface Laplacian and throughfall and water table time series are provided inCobb and Harvey (2019).

The throughfall data are the average of data from four siphoning tipping-bucket rain gauges (Texas Electronics TR-525S, Dallas, Texas, USA) installed 50 cm above the peat surface along a 100 m transect, as described in Cobb and Harvey (2019). The coordinates provided for the throughfall measurements (in locations dataset) are the coordinates of the mid-point of the 4 throughfall gauges. The coordinates of the individual throughfall gauges were:
Gauge 1: 114.354260, 4.370139
Gauge 2: 114.354034, 4.369900
Gauge 3: 114.353943, 4.369769
Gauge 4: 114.353661, 4.369449
The centroid of these 4 locations (recorded in locations dataset) was found by converting the coordinates of each gauge to a local projected coordinate system (GDBD2009, EPSG:5247), averaging the northing and easting coordinates, and converting back to longitude-latitude coordinates (EPSG:4326).
