This study reports on the impact of rainfall patterns and land surface changes flood dynamics in Meijiang River Basin, located upper reaches Ganjiang River. We formulated a range spatial distribution scenarios employed MIKE SHE model to evaluate variations volume, peak, timing peaks. found that under comparable areal conditions, volumes fluctuated by up 6.22% among different patterns, whereas peaks exhibited differences 36.23%. When center moved from upstream downstream, both volume peak initially increased before decreasing, with maximum values 4.2 billion m3 4900 m3/s, respectively. selected three basin scales (i.e., 10,000, 1000, 100 km2) for comparative analysis. In period between 1985 2020, conditions resulted decreases basins 7.61, 11.53, 15.79%, respectively; reduction 6.58, 9.60, 10.48%, delayed times 3, 2, 2 h, The results this show significant influence exerted location centers, processes. particular, when area was reduced, underlying more obvious. These also prediction needs consider complex interaction multiple factors.

Study region: Tabu Basin is located on a typical-deserted steppe in Inner Mongolia, China and plays significant role maintaining ecological stability of northern China. focus: Among rivers worldwide, 51–60 % cease to flow for at least one day annually, especially arid semiarid areas. Understanding interactions between intermittent (IRs) groundwater (GW) crucial protecting water resources sustaining balance. A comprehensive framework was developed analyze these interactions. New hydrological insights the Unlike previous studies, this study considered seasonal differences hydrochemical isotopic compositions IR GW, as well intensive influence evaporation. Multitemporal datasets were employed IR–GW interaction across spatial, temporal, profiling scales. Hydrochemical evidence analysis indicated input meltwater with depleted signatures GW recharge IR.

Inner Mongolia Reaches of the Yellow River Basin (IMR-YRB) in China, knwon as "Jiziwan" economic belt. High spatio-seasonal resolution sampling data surface waters IMR-YRB were applied (189 samples collected from 63 sites during wet (July 2021), dry (October 2021) and normal (April 2022) seasons). The testing results stable H O isotopes combined with backward wind trajectory modeling geostatistical analysis to identify characteristics water cycle its controlling factors. showed that mainly recharged by precipitation summer monsoon, resulting depleted isotopic contents (low δ18O high d-excess) season. In contrast, most characterized enrichment (high low seasons, which was attributed effects continuous evaporation. addition, there some exhibited depletion seasons due groundwater discharge or snowmelt recharge. Overall, this study improved understanding at a large-scale basin for hydrologic processes other regions.
