The third issue of Evidence in Earth Science (Vol. 1, No. 3) highlights advances in hydrology and ecosystem research under climate change. Xie et al. analyze the “7·29” flood in the Haihe River Basin using a distributed hydrological model, offering valuable insights for flood control and risk assessment. Yan et al. provide a bibliometric review of forest evapotranspiration estimation, tracing its evolution from field observation to intelligent, data-driven modeling. Together, these studies exemplify the journal’s mission to promote evidence-based research that integrates Earth system processes with sustainable environmental management.
