Table 4

Mean simulated the highest peak dissolved nitrogen loads in water discharge (QN) from surface water runoff from outlet at T6.4 at Colusa National Wildlife Refuge, after winter/spring flooding periods of current irrigation management and three scenarios during historical (2015 to 2018) and future periods (historical Tmax + 5.56°C). In scenarios 1 and 2, current irrigation volumes were increased by 1.5 and 3 times, respectively. In scenario 3, the current irrigation volume was decreased by 0.5 times. IRR indicates water amount used for wetland irrigation.
