Why? • Valuable resource - Costly - Strategic • Fragile • Access - Key personnel - Data loss - Documentation • Access - Inclusion of new users

Studies Amatole Berg Breede Upper Crocodile Fish-Sundays Upper Olifants Olifants-Doring Upper Orange Upper Vaal Vaal Barrage Middle Vaal Lower Vaal Missing: - Vaalharts - Mgeni - Current studies

Models DISA WQS FLOSAL WQ2000 IMPAQ WRPM NACL01 NACL02 NACLBAR NACLS WQT WQS WQ2000 WRPM

Limitations • Model versions • Incomplete data • Set-up procedures

• Catchment salinity • Catchment sulphate Model categories (1 of 2) • Catchment salinity - WQT (monthly) - FLOSAL (monthly / daily) - WQ2000 (monthly) - NACL01 (daily) - NACLBAR (daily) - NACL02 (daily) • Catchment sulphate - NACLS (daily) - WQS (monthly)

Model categories • System salinity / sulphate • Irrigation salinity (2 of 2) • System salinity / sulphate - WRPM (monthly) • Irrigation salinity - DISA (daily) • Salinity, phosphate, SS, E-coli, Chlorophyll-a - IMPAQ (monthly)
