The process of modeling contaminants transport includes the following steps:
- 3D modeling of contaminated site.
- Simulation and Modeling of Water Flow in Soil.
- Modeling of contaminants transport in soil.
- Modeling of Environmental Thermal Pollution.
- Analysis of spatial data.
- Analyses on contaminant profiles using stochastic modeling.
3D Modeling of Contaminated Site
On the basis of the information provided by our client we choose boundaries of the area and the quantity of considered aquifers. In order to obtain correct simulation results, the boundaries of the area are chosen in such a way that the groundwater level or flow rate is known. In order to ensure this requirement, it is recommended to choose the modeling area boundaries along rivers, lakes and waterfront lines.
Further, on the basis of elevation level maps and water wells data with the lithological description, a 3-D model of the hydrogeological object is made.
With well-known groundwater levels, infiltration values and seepage parameters of the hydrogeological model can be refined by calibrating the groundwater model.
Simulation and Modeling of Water Flow in Soil
Using filtration equations, the distribution of groundwater heads a hydrogeological site is computed and direction and speed of the flow is determined.
Modeling of Contaminants Transfer in Soil
Taking into account water transport results and the distribution of groundwater levels of the site, we calculate the contaminants transport in soil.
Modeling of Environmental Thermal Pollution
We calculate heat propagation from some industrial heat source (thermoelectric power station, nuclear power station) or by injection of hot liquids into groundwater (e.g. during mining operations).
Analysis of the Spatial Data
With information about groundwater levels, contaminants concentration in given wells, or other kinds of spatial data, we calculate spatial distribution in a certain region.
Stochastic modeling allows us to make a risk assessment of contamination in water bodies (water wells, reservoir, river, etc.) and helps to make direct management decisions.
If we simulate the spread of contaminants, we will obtain not a specific value of the pollutant concentration, but the probability of its presence in some areas. These results will be more reliable while assessing the risk of getting certain pollutants into water bodies (water wells, reservoirs, rivers) and will help you make the right managerial decision.
Our experts will help you solve problems like modeling groundwater flow and contaminant transport, as well as calculation of contaminants ingress intensity from the soil surface to groundwater, water pollution risk assessment, etc.
