Land use and land cover change (LUCC) water resource utilization behavior policy (WRUBAP) affect the hydrological cycle in different ways. Their effects on streamflow balance components were analyzed Yiluo River Basin using delta method Soil Water Assessment Tool (SWAT). The multivariable (runoff actual evapotranspiration) calibration validation was used to reduce model uncertainty. LUCC impact (1976–2015) evaluated through comparison of simulated paired scenarios. WRUBAP runoff assessed by...

To enable local water resource management and maintenance of ecosystem integrity to protect mitigate against flood drought, it is necessary determine changes in long-term series streamflow distinguish the roles that climate change human disturbance play these changes. A review previous research on detection attribution observed annual runoff China shows a decrease since 1950s northern areas such as Songhuajiang River resources zone, Liaohe Haihe Yellow Huaihe Zone. Furthermore, abrupt...

Monthly temperature and precipitation time-series for the Zhujiang River Basin are analyzed in order to identify changes climate extremes. Daily data from 1961 2007 of 192 meteorological stations used. Two indicators (monthly mean monthly maximum mean) three total, consecutive 5-day precipitation, dry days) analyzed. Tendencies all five can be observed. Many show significant positive trends (above 90% confidence level) temperatures temperatures. For months, a increase observed entire basin...

Abstract. To quantify climate change impact and difference on basin-scale river runoff under the limiting global warming thresholds of 1.5 2.0 ∘C, this study examined four basins covering a wide hydroclimatic setting. We analyzed projected in basins, quantified annual seasonal based Soil Water Assessment Tool, estimated uncertainty constrained by circulation model (GCM) structure representative concentration pathways (RCPs).

Extended-range runoff forecasting is important for water resources management and energy planning. Experimental extended-range was hindcasted, based on an climate model, developed by National Climate Center of the China Meteorological Administration, semi-distributed hydrological model HBV-D. The skill forecasts explored using mean square score (MSSS), anomaly correlation coefficient (ACC), areas under relative operating characteristics curve (AUC) three terciles experimental 51-day periods...

China is committed to achieving carbon neutrality before 2060. This study projected the changes in climate and runoff source region of Yellow River Basin for 2021–2060 under lower emission pathways (SSP1–2.6 SSP2–4.5) using a statistically downscaled dataset SWAT hydrological model. Results showed that will become warmer wetter from 2021–2060. In comparison with baseline period (1995–2014), terms ensemble mean, annual mean air temperature, precipitation, increase by 1.3 °C 1.6 °C, 11.1%...

Wind and rainfall climatic erosivities are important parameters with which to assess the possible effects of conditions on erosion. In this study, wind erosion erosivity (C-factor) (Rday-factor) were calculated for period 1970–2020 based data from 50 meteorological stations in Qinghai Province. The Mann–Kendall test, trend analysis, K-means clustering method used explore spatiotemporal characteristics regional wind/rainfall erosivity. Results showed that annual mean value C-factor was 25.8...

Abstract Replacement of water in a given hydrological component is one the effects cycle. We introduce concept renewal time to express rate replacement specific reach river. Based on stream‐flow data from 1990s, simple formula used estimate times for several reaches middle and lower sections Yellow River (Huanghe) China. These estimates reveal following trends: (i) are shortest during May–October period (ii) annual tend decrease when moving downstream reaches. Copyright © 2003 John Wiley...
