Rivers and Lakes

Rivers are naturally flowing waterbodies which drain a catchment that acts as a collector of all kinds of water and pollution. Lakes often act as receiving basins downstream from the surrounding catchment. Lakes have the ability to modify the inflows from the rivers, serving both as filters and buffers. They retain water, sediment, toxins, and nutrients in response to in-lake hydrodynamic, chemical, and biological processes and can dampen the extremes of discharges.

Water Quality
The main parameters typically modelled for water quality studies in river and lake systems include; flow velocity, water temperature, sediments, pathogens, dissolved oxygen and nutrients.

Modelling
To better understand and to realistically simulate the physical, chemical, and biological processes in rivers and lakes, MarCon employ a number of industry standard modelling applications such as BASINS, SWAT, SIMCAT, RIVPACS, FASTER, ISIS, DIVAST, and others, to simulate the various interactions between the surface waters of rivers and lakes, the surrounding catchment(s), and coastal waters.
