Study on Runoff Evaluation Law in the Luanhe River Basin, China

Abstract

River water is necessary for production, livelihood and ecological balance [1]. Changes in river runoff directly affect the development and utilization of water resources [2] and thereby societal and economic development [3]. Studying the evolution of runoff and its influencing factors can provide a scientific basis for the management, protection and sustainable use of water resources [4, 5]. The change in river runoff is an important manifestation of climatic influence, especially precipitation and human activities in basins [6]. Thus, river runoff is an active area in global change research [7,8]. The fifth assessment report of the United Nations Intergovernmental Panel on Climate Change (IPCC) predicts that in the 21 st century, global climate change will increase surface runoff in high-latitude regions and humid tropical regions and decrease surface runoff in most arid subtropical regions and Mediterranean regions [7]. However, the causes of runoff changes are complex. Although climate change [8, 9] (e.g., precipitation) is the main influence in river runoff changes, the potential increase in evapotranspiration is also considered to be

Spatial and temporal changes of runoff in the Yellow River in recent 15 years

“…This phenomenon may be determined by runoff distribution and water consumption in the Yellow River Basin. As reported by Shan et al (2021), precipitation and human activities in the basin are significant factors affecting river runoff [13].…”

Multi-model analysis of historical runoff changes in the Lancang-Mekong River Basin – Characteristics and uncertainties

“…Employing the hydrological models makes the investigation of spatiotemporal changes to runoff possible. It further improves our understanding of regional hydrological cycle changes, which could support water resource management, protection, and sustainable use (Shan et al, 2021).…”

Evaluating the influence of hydrological condition on the phosphorus loads in an agricultural river basin using the SWAT model

“…The basin receives an average precipitation total of 560 mm. The average annual runoff of the river is 4,694 million m 3 , 70-80% of which occurs in the period from June to September (Shan et al 2021). The major vegetation types in the Luanhe River basin include cultural vegetation, bush wood, plateau and broad-leaved forests, and a small area of coniferous forests and meadows (Li et al 2015).…”
