Online Environmental Solutions (OES) provides a variety of services from very basic mass balance calculations to more complicated ecological and hydrodynamic models. The following table gives examples of projects that OES can provide solutions for.

Example	Problem	Input Data	Output Data	Solution
Wastewater Pond	Waster water is pumped into a containment pond. Company needs to know the rate of outflow to ensure minimum environmental standards are met.	Pond Bathymetry Inflow rates Chemical composition of inflow Local meteorological data Environmental standards of outflow Reaction rates for breakdown of waste material.	Compete Mass Balance Scenario Modelling	Recommended rates of outflow as a function of volume and chemical composition of inflow.
Carbon Calculator	Company needs to know what measures can be taken to offset carbon emissions.	List of all carbon emissions Daily averages for each emission over an annual time period List of possible offset measures Rate of carbon sequestration and temporal variation for each offset measure. Costs of each offset measure	Carbon model of existing practices Scenario modelling for future practices Cost benefit analysis for each carbon off sets	Recommendations based on current practice on how carbon emissions can be minimised, sequestration maximised while minimising economical impact.
Regression Analysis	Fish stocks in a lake are low. Managers need to know the cause(s), changes in fishing practices, food sources or abiotic factors such as climate change.	Historical data both spatial and temporal to include: Fish stock; Fish catch; Meteorological data; Nutrient and light concentrations in the water column and Plankton concentrations.	Graphical and regression analysis showing links and patterns between all components of the lake ecosystem both biotic and abiotic.	Recommendations for changes that can be made to lake management practices to improve fish stocks.
Linked ecological and hydrodynamic numerical modelling	As Above.	As above and to include: Bathymetrical data.	Daily output on nutrient cycles, phytoplankton, zooplankton and fish concentrations. Additional scenario modelling to predict future trends under alternative lake management practices as well as changes in climate data.	Recommendations for changes that can be made to lake management practices to improve fish stocks.
