Calculated specific conductance using PHREEQCI PHREEQCI is a widely-used geochemical computer program that can be used to calculate chemical speciation and specific conductance of a natural water sample from its chemical composition (Charlton and Parkhurst, 2002; Parkhurst and Appelo, 1999). The specific conductance of a natural water calculated with PHREEQCI (Appelo, 2010) is reliable for pH greater than 4 and temperatures less than 35 °C (McCleskey and others, 2012b). An alternative method for calculating the specific conductance of natural waters is accurate over a large range of ionic strength (0.0004–0.7 mol/kg), pH (1–10), temperature (0–95 °C), and specific conductance (30–70,000 μS/cm) (McCleskey and others, 2012a). PHREEQCI input files for calculating...

This archive contains results of lagrangian particle-tracking (LPT) simulations of both the dispersal of rhodamine dye and larval drift. The LPT model is a research effort and the simulations here provide some of the first experimental validation of the results for dispersal of a conservative constituent (Rhodamine WT-20). The larval drift simulations however have not been validated and the results should be viewed in this context. The simulations may contain 20 - 30 Gb of results. The archive is split into child-items to help distinguish the individual components of the archive and make downloading of large files...

Code used to produce the data is also included. The dataset is produced using a multiple-model approach. First, downscaled global climate model outputs are used to drive an existing Variable Infiltration Capacity/Variable Infiltration Capacity Routing (VIC/RVIC) model of Sacramento/San Joaquin hydrology, resulting in projections of daily, unimpaired flows throughout the watershed....
