Two-dimensional variably saturated heat and flow models (VS2DH) were used to examine seepage rates at 19 transects in the Truckee Canal system during the 2018 and 2019 irrigation seasons. The models were calibrated to unsteady stage conditions over a 2,500 hour period, then parameter values were validated for the remaining irrigation period of each year. Regression equations were developed for each transect based on the model output, measured sediment temperature at 0.0 meters depth, stage, and hydraulic the gradient between surface and groundwater (where data were available). This USGS data release contains the model input and output files for simulating seepage rates along the Truckee Canal. Details and results...

This USGS data release presents tabular data and a model archive used to estimate seepage rates at 19 locations on the Truckee Canal for the 2018 and 2019 irrigation seasons. This supplemental data release consists of two child items: (1) Model archive of two-dimensional variably saturated heat and flow models (VS2DH) used to examine seepage rates in the Truckee Canal at 19 transect locations (model archive), and (2) ​Tabular data of site locations, sediment and water temperature, and canal head or stage in the Truckee Canal (tabular data).

This USGS data release child item presents tabular data of temperature and canal stage measured at 19 locations on the Truckee Canal for the 2018 to 2019 irrigation seasons. Data were collected to inversely estimate hydraulic and thermal soil properties and seepage rates. The child items consist of: (1) Site locations of 19 transect locations in the Truckee Canal (tabular data), and (2) Sediment temperature, water temperature, and canal stage in the Truckee Canal (tabular data).
