Numerical Modeling Services

Numerical modeling is a powerful method of visualizing the dynamic behavior of physical systems. We have developed 1D, 2D and 3D models capable of accurately simulating water circulation in

  • Rivers
  • Estuaries,
  • Coastal waters and
  • Continental shelf and deeper waters

All the models are founded solidly on the science of fluid mechanics / dynamics for circulation including such natural forces as

  • Tides
  • Density stratification and buoyancy
  • Wind stress
  • Drag arising from shore line and bottom
  • Coriolis etc.

Apart from the above, several software under the group name "HYDRODYN" were developed – for Air pollution, Surface pollution, Ground Water pollution and Fluid Dynamics simulation etc.

Numerical modeling plays an important role in the design of any proposed development project as it helps delineate qualitative and quantitative assessment of the potential impact on surroundings. Whether a proposed development implies physical, chemical or biological “footprint” in the aquatic /terrestrial / spatial environment, the development of more reliable and user friendly models make it easier and more economically feasible to assess and evaluate the effects and to separate natural fluctuations from actual impacts. The application of models assists decision makers in many ways.

For Example:

  • in site selection and evaluation of its appropriateness for a given purpose
  • through assessment of design conditions as basis for dimensioning structures
  • by isolating and reducing the un-certainties with respect to anticipated environment changes
  • through evaluation of different layouts or scenarios of measures ensuring that the most cost effective layout or approach is adopted.

Also for operational and planning purposes, numerical models are indispensable tools in decision making.

For example:

Using integrated monitoring and modeling systems to simulate the conditions in real time and make predictions typically few days ahead for ---

  • Emergency planning and disaster management ( flood forecasting, clean-up assessment due to accidental spills of oils. Pesticides etc)
  • Optimization of reservoir operations
  • Water quality control etc.
