DSM2 Input 2025-07-03 historical update
DSM2 Version "DSM2 Input 2025-07-03 historical update" is based on "DSM2 Input 2025-05-28", and includes the following improvements: * Corrections to SMSCG time series input for the RADIAL_FRACT_UP and RADIAL_FRACT_DOWN time series. * Modified pipe coefficients for False River Barrier and the South Delta Temporary Barriers. Previously, some of these coefficients were greater than 1.0, which is used in SCHISM to simulate barrier leakage. Since barrier leakage in DSM2 is simulated differently, the coefficients do not need to be greater than 1.0.
