Measuring the degree of hydrological variability of riparian wetland using hydrological attributes integration (HAI) histogram comparison approach (HCA) and range of variability approach (RVA)

Hydrological variability (HA) in the river due to damming is well explored but there is a dearth of research about the HA on the riparian wetland. Time series data scarcity perhaps withstands against such research. The present work intended to measure the degree of HA of the river using flow data of...
