WATER QUALITY MODELLING
Water quality assessment
We examine the relationship between water movement and water quality to support management of lakes and other water bodies.
When this service is useful
- When assessing changes in lake, estuarine or marine water quality
- When analysing algal bloom causes and related conditions
- When organising monitoring data to examine management options
Approach and scope
- Numerical modelling of water quality and flow, including Delft3D
- Data analysis related to algal blooms and water-quality change
- Statistical examination of monitoring trends and unusual conditions
Information to prepare
- Terrain, bathymetry and inflow and outflow conditions
- Water-quality, meteorological and hydraulic observations over time
- Management alternatives and assessment objectives
You can start a discussion with the information currently available, even if every item is not yet ready.
Potential deliverables
- A summary of observations and water-quality trends
- Model results under the specified conditions
- Analytical material for comparing management alternatives
Deliverable types and scope are agreed according to objectives, available information and project requirements.
Frequently asked questions
Can monitoring data be examined before modelling?
After reviewing data duration, frequency and variables, available statistical and trend analyses can be considered.
Do model results guarantee water quality at all times?
Results depend on the available data and assumed conditions. Observation coverage, model assumptions and application limits are documented together.
