Heat can be used a tracer for monitoring seepage rates within stream channels. To estimate seepage using temperature, the diel amplitude and attenuation of temperature at several depths below the streambed must be monitored, as well as the frequency and duration of streamflow in a channel (Narranjo and Smith, 2016). Special subsurface temperature rods (TRODS) were developed to address these most of these needs (Narranjo and Turcotte, 2015). A TROD consists of discrete temperature iButton sensors within a .75 inch (in) diameter 1 meter (m) long sealed, water-proof PVC pipe to prevent water damage to the sensors. A TROD is installed into stream channel sediments and measures surface water and sediment temperatures...

The San Antonio Creek Valley watershed (SACVW) is located in western Santa Barbara County about 15 miles (mi) south of Santa Maria, California and 55 mi north of Santa Barbara, California. The SACVW, is about 140 square miles and encompasses the San Antonio Creek Valley groundwater basin; From the late 1800s, groundwater has been the primary source of water for agricultural, military, municipal, and domestic uses. Groundwater withdrawal from pumping has exceeded the amount of water replenishing the basin, causing groundwater declines of more than 150 feet in parts of the valley between 1943 and 2017, and reducing base flow in San Antonio Creek at the western end of the SACVW. Agricultural water use (primarily for...

Infiltrometers are devices used to measure the infiltration rates of water into soils or porous media (Bouwer, 1986). Cylinder infiltrometers are generally constructed from metal shaped into cylinders which are driven into the ground and flooded with water. The rate at which water infiltrates into the ground is measured until the rate of infiltration is constant to capture unsaturated infiltration rates and beyond steady state to measure saturated infiltration rates and conductivity (Bouwer, 1986). Infiltrometers are typically employed to measure the rate of infiltration on inundated soils such as surface irrigation, seepage from surface water such as streams or reservoirs, or infiltration basins for groundwater...

To determine aquifer properties in the San Antonio Creek Valley watershed (SACVW) single well air and physical slug aquifer tests were conducted on seventeen monitoring wells at nine sites beginning on August 7 2017 and ending on August 13, 2017 . For all tests either a physical or air slug was used based on the distance of the groundwater level from the perforated interval of the well. A physical slug was used if the distance from the groundwater level to the top of the perforated interval was less than seven feet (ft); otherwise an air slug was used. above the screened interval than a physical slug was used. Physical slug tests were used in order to produce enough change in groundwater levels to adequately characterize...

Streambed instruments that measure electrical resistivity were constructed and installed along the main channel in San Antonio Creek and along tributary streambeds in order to provide insight into intermittent streamflow not recorded by traditional stream gaging stations. These instruments can record high-resolution temporal and geographic responses of streamflow to precipitation in intermittent streams. Streambed electrical resistivity sensors (SERS) and stream temperature, intermittency, and conductivity sensors (STICs) are small, cost-effective, instruments that can be installed (and re-installed) along stream reaches to measure stream intermittency. These instruments employ water contact electrodes to record...
