摘要

基流指数是流域尺度水平衡研究中的一个关键参数。然而，由于各种原因，它经常被忽视，即几乎不可能直接测量，模型的简化，以及水文气象数据的不存在。因此，在本研究中计算了Ramganga河流域的基流，此前尚未对其进行科学评估。分类存档的观测河流流量数据来自中央水利委员会（CWC），并应用于分析过滤器中，以评估Ramganga河流域所有现有CWC水文气象站点的基准流量指数（BFI）。CWC站点的BFI平均值在27%至38%之间。研究结果与流域水文特征相一致，具有重要意义。还讨论了这些结果，以解释各种可能的人为影响，这些影响被评估为没有重大影响。

Baseflow index assessment for agriculture-industry led Ramganga river basin

The baseflow index is a crucial parameter in basin-scale water balance studies. However, it has frequently been neglected for various reasons, viz. near-impossible direct measurement, simplification of the model, and non-existence of the hydro-meteorological data. Hence, baseflow is computed for the Ramganga river basin in the present study, for which a scientific assessment had not been done previously. The classified-archived-observed river discharge data are obtained from Central Water Commission (CWC) and are applied in an analytical filter to assess the baseflow index (BFI) at all exiting CWC hydro-meteorological sites in the Ramganga river basin. The average values of BFIs for the CWC sites vary between 27% and 38%. The results are found to be consistent and showed significance with the hydrological characteristics of the basin. The results have also been discussed to account for various possible anthropogenic effects, which are assessed as having no significant impact.
