7. What is ECO Lab?
•Process equation solver for coupled ordinary differential equations
•Designed to describe processes of chemistry, ecology etc.
•It calculates the rate of change of any type of state variable given any number of related variables, processes and forcing
•Integrated with DHI’s hydrodynamic models

•Irrigation: surface and groundwater abstractions
•Drainage: agricultural runoff
Objectives
•Integrated eco-hydrological model
•Quantify changes in ecological status
•Development of land management scenarios
Scenarios
•Reduction in GW abstraction 10%, 20%, 30%

To do next:
•calculate the N contribute of the different sources to the river
•model the N transformation processes
•model how the biota reacts to the N in the environment
•investigating potential changes to wetland design and characteristics in order to increase the nutrient retention capacity
