#DWCZ-MEF-Data from Warix et al. (2023), Local topography and hydraulic conductivity influence riparian groundwater age and groundwater-surface water connection

##OVERVIEW
###Description/Abstract

###Manitou_2021_SW_GW_chemistry

Dataset contains chemistry data from 8 paired groundwater (GW) and surface water (SW) sites along Hotel Gulch in the Manitou Experimental Forest. Sample ID describes the site location (GW or SW (n)) and the date the sample was collected. Sample collection time is listed in the second column.

Field parameters include specific conductivity (µS/cm), pH, and temperature (˚C). Cations include Al, Ba, Ca, Fe, K, Li, Mg, Mn, Na, Ni, Si, and Sr, all reported in mg/L. Cation data were analyzed with an ICP-AES. Anion data include F, Cl, NO3, SO4, and HCO3. Anion data were analyzed on an IC, and HCO3 was estimated from alkalinity data. Alkalinity is reported as mg/L as CaCO3.

High charge balance error is hypothesized to be due to underestimating sulfate and/or error associated with alkalinity measurements.

###Data flags include:
NaN = data was not collected
BDL = analyte is below detection limit
DRY = data was not collected because the stream was dry.

###Manitou_Warix_2021_timeseries.csv

Dataset for Hotel Gulch discharge, stream specific conductivity, groundwater level, and groundwater specific conductivity at eight paired groundwater and stilling wells.

Electrical conductivity was measured with Onset U-24-001 HOBOs and converted to specific conductivity. Water level was measured with Onset U-20-001 HOBOs in both the stream and groundwater wells. We measured discharge using the salt dilution method and created rating curves to convert stream water level to discharge; only discharge is reported here.

NaN values indicate that data are not available because the sensor was not yet launched, was being downloaded, or due to logger error. Discharge values were also converted to NaN where stage values exceeded manual stage/discharge observations to avoid overestimating discharge during high flows.

###Units:
Discharge = liters/second
Groundwater elevation = meters
Specific conductivity = microsiemen/centimeter

###Temperature Profiles (TS(n))

Temperature data are saved in individual files for each of the 8 sites. File names are TS(n).csv where n = the site ID. Column headers are the depth under the streambed in meters, and all temperature data are in Celsius.

Temperature was collected with DS1925L-F5# Thermochron iButtons at 0 cm, 10 cm, and 20 cm below the stream bed. At site 7, the 20 cm iButton failed, so temperature data at this depth were taken from an Onset U-24-001 HOBO recording in the adjacent groundwater well at a depth of 1.43 meters.
