Salinity Simulation with WRAP - Technical Report No. 317 - July 2009

Sep 18, 2026

Salinity Simulation with WRAP presents a technical framework for modeling salinity dynamics in water availability systems using the WRAP approach. It details salinity aspects relevant to simulation, including spatial configuration and salinity input datasets. The report describes computer programs (SALIN and SALT), their input records, and how volumes, loads, and concentrations are handled. It also provides simulation results, time-series and reliability tables, parameter calibration comparisons, and worked examples with preparation instructions in multiple appendices.
