Yamuna Basin - Flow Health Assessment
• Incorporating hydrology into river health• Need a simple measurement of hydrology that relates to ecology, and human disturbance
– Require a score for each year• Hydrology can be directly controlled to improve/maintain health
– Score should inform the appropriate response
• 9 hydrological sub indicators– High Flow (HF)– Low Flow (LF)– Highest Monthly (HM)– Lowest Monthly (LM)– Persistently Higher (PH)– Persistently Lower (PL)– Persistently Very Low (PVL)– Seasonality Flow Shift (SFS)– Flood Flow Interval (FFI)
