Documentation of VS2DH Canal Seepage Models: Incorporating temperature into seepage loss estimates for a large irrigation canal

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 of the model simulations are described in an associated report.
