| Abstract: | Criticality of Surface Water Quality means the value of its physico-chemical parameters exceeding the specified limits and thus becomes of great importance due to their probable environmental impacts. The term was coined for intra-comparison between various parameters that determine the Water Quality. The Concept of Criticality Index is to assess the relative criticality of various parameters for Riverine Systems. These parameters are very many and include notable such as COD, DO, TDS, pH, etc. Normally, in water quality determination for river stretch, equal importance is given to all parameters and often the fact that certain parameters, more critical than others is neglected. This study emphasizes on this fact and works on related known concepts and logics, and developed the Index which is beneficial in identifying the critical parameters for river stretches. This is useful in prioritizing the mitigation measures due to their inherent characteristics. |
