Urban watershed eutrophication state monitoring using aquatic plant based technology

Eutrophication is always associated with excess nutrients of nitrogen and phosphorus. Excess nutrients can trigger undesirable eutrophication, resulting in unhealthy algal blooms, spreading of certain aquatic macrophytes, depletion of oxygen and loss of key species, resulting in widespread degradati...
