California Climate and Hydrology
Change Graphs

This graphing tool presents climate and hydrology data values from the California Basin Characterization Model dataset plotted over time for 156 hydrologic basins (HUC-8 basins) that comprise hydrologic California. You can select a basin by clicking on it on the map on the left; hover your mouse to see basin names. You can select a data variable and a smoothing period on the right, then click "Draw".

Historical and projected future values for that basin and the chosen data variable are plotted on the same graph. The four future climate scenarios were selected to demonstrate a range of precipitation and temperatures projected by the 18 scenarios available from the BCM; they are: MIROC-esm RCP 8.5 (warmest, driest), CRNM RCP 8.5 (wettest and warm), CCSM4 RCP 8.5 (mid-range, closest to ensemble mean), and GFDL A2 (a moderately warmer, drier future).

Click on the legends below the graphs to hide/show particular lines in the future climate scenarios graphs (draw button click not needed for this)
