Details of our service in Groundwater Modelling

Our groundwater modelling services can be used to assess many engineering problems where groundwater and surface water flow are impacted by one another, including:
  • The impact of groundwater extractions on surface water low flows.
  • The impact of storm events on bank infiltration rate.
  • The travel time to the water wells

Groundwater Recharge

We include climate simulation and hydrological budget simulation by using SWAT. The SWAT model estimated other relevant water balance components in addition to the annual and monthly flow. The most important elements of water balance of a basin are precipitation, surface runoff, lateral flow, base flow, and evapotranspiration. Among these, all the variables, except precipitation, need prediction for quantifying, as their measurement is not easy.

Conceptualization of Groundwater Model

Input data requirement for the model includes hydraulic property, initial conditions, boundary conditions, groundwater extraction and groundwater recharge. For 3D modelling, hydraulic conductivity and specific storage are the most important hydraulic property. These parameters are usually estimated from the pumping test data. In this study, the hydraulic property (transmissivity and hydraulic conductivity) are estimated from correlation between pumping test data and geoelectrical parameter. Vertical hydraulic conductivity is taken as 0.1 of horizontal hydraulic conductivity. For 3D modelling, hydraulic conductivity and specific storage are the most important hydraulic property. These parameters are usually estimated from the pumping test data. The hydraulic property (transmissivity and hydraulic conductivity) will be estimated from correlation between pumping test data and geoelectrical parameter. Vertical hydraulic conductivity will be taken as 0.1 of horizontal hydraulic conductivity. Recharge will be assigned on the top surface of the model as it takes place from the top layer. The groundwater may be recharged by shallow recharge and irrigation return flow. The conceptual model will include the following aspect:

Model Boundaries
The model boundaries are demarcated.
Boundary Conditions
The boundary conditions are configured, assigned and interpreted.
Model Framework
The physical framework of the conceptual model (layer, horizontal and vertical discretization) is designed
