Oct 2007: AQUARIUS - Model of River Dee system (North Wales) completed. 3 reservoirs, 55 river reaches, 26 flow points, 8 river abstractions, 21 supply aqueducts, 6 transfer aqueducts, 3 treatment works, 11 water demands, 3 drought conditions.
Jul 2007: AQUARIUS - Facility added for 'time of travel' through River Reaches, based on up to 7 daily routing coefficients.
Jun 2007: AQUARIUS - Facility added for 7 day 'real time' simulation. Inflow forecasts can be set according to specified 'probability of exceedence' of historic time series values.

Jan 2007: AQUARIUS - Facility added to randomly generate daily flows based on calendar monthly Normal (Gaussian) or Pearson Type III probability distributions. To simulate operation of hydro plant at sites without coincident streamflow records.
Dec 2006: AQUARIUS - Program demonstrated at International Symposium on Water Resources & Renewable Energy Development in Asia, Bangkok 30/11/2006 & 1/12/2006.
Nov 2006: AQUARIUS - Program installed in offices of United Utilities Water, Warrington, UK for evaluation.
Jan 2006: AQUARIUS - Model of United Utility Water's Integrated Water Resource/Supply system constructed. 19 reservoirs, 44 river reaches, 29 flow points, 13 river abstractions, 11 water sources, 19 treatment works, 14 pumping stations, 36 supply aqueducts, 74 transfer aqueducts, 16 junction points and 23 water demand areas.
Oct 2005: AQUARIUS - Modelling of Wind Plants included with random number generation of daily and compatible hourly (load block) wind speeds and defined efficiency function conversion to power output. Enables accurate assessment of wind power values within hydro-thermal power systems.
Aug 2005: AQUARIUS - Optimisation of long-term weekly or monthly stored water values using Stochastic Dynamic Programming Algorithm.
