Abstract This study employs an event‐based approach to analyse drought propagation from meteorological hydrological via agricultural in the semi‐arid Krishna River basin of India. The Standardized Precipitation Evapotranspiration Index (SPEI), Soil Moisture (SSMI) and Streamflow (SSI) representing meteorological, drought, respectively, were estimated. Two different cases are analysed: meteorological‐to‐agricultural (SPEI‐to‐SSMI) agricultural‐to‐hydrological (SSMI‐to‐SSI). is analysed using three‐time matrices, namely time difference between initiation (), peak () termination at multiple timescales 1, 3, 6, 9 12 months threshold values 0, −0.5, −1 − 1.5, delineate shifts mild extreme conditions detail. results indicate that SPEI‐to‐SSMI decreased for most tributaries values, whereas it increased significantly SSMI‐to‐SSI drought. changes with respect as well magnitude (intensity severity). factor ( PF ), defined ratio average value succeeding preceding characteristics, has also been studied. For duration shrinks across all expands On other hand, severity intensity magnify experiences dampening effects Thus, proposed provides valuable insights into dynamics, aiding managing mitigating droughts river elsewhere.

The Ganga River (known internationally as the Ganges) is one of world's most prominent rivers, running from Himalayas to Bay Bengal and supporting livelihoods > 40 % India's 1.4 billion population. regionally globally important, agriculture industry, yet faces potentially detrimental water quality challenges arising runoff discharge increasing urbanization, industry agriculture. A ∼ 2700 km longitudinal survey nutrient microbial quality, including phytoplankton composition, was undertaken in November 2019. aim investigate if how anthropogenic activities (e.g. urbanisation, agriculture) tributary convergence (potentially reflecting both human activity flow influences) affect shift physicochemical, nutrient, parameters along river continuum. Segmented regression identified four zones distinct nutrient/microbial characteristics River, with breakpoints located near Kanpur, Varanasi downstream Farakka Barage, at distances 1020, 1500 2350 Himalayan source. Population density, land use urban cover were associated selected parts catchment, elevated chemical concentrations likely agriculture, sewage inputs.

Downstream shifts observed throughout This information can help prioritize locations for targeted monitoring and/or remediation interventions has illustrated an approach quantify impacts inputs on major systems, such River.
