Abstract Global warming and anthropogenic changes can result in the heterogeneity of water availability spatiotemporal scale, which will further affect allocation resources. A lot researches have been devoted to examining responses global while neglected future changes. What’s more, only a few studies investigated response optimal resources projected climate In this study, cascade model chain is developed evaluate impacts change human activities on Firstly, large set models (GCMs) associated...

Riverine blooms have become a challenging global environmental problem owing to strong disturbances from intensified human activities and the construction or operation of hydraulic projects. Previous studies mainly paid attention algal in lakes reservoirs, while less focused on prediction prevention large rivers. As one highly regulated rivers China, downstream Han River frequently occurred consecutive recent decades, was selected as case study. Firstly, during 1992–2021 were investigated...

Understanding the differences in rhizosphere soil microbial metabolites between severely and mildly rocky desertified areas is crucial for developing ecological restoration strategies land management measures desertification regions. This study systematically analyzed of Toona sinensis , Vernicia fordii Cornus wilsoniana Western Hunan using untargeted metabolomics. The results showed that types quantities primary secondary were significantly lower than those areas. Additionally, under severe...

Abstract. Understanding the projection performance of hydrological models under contrasting climatic conditions supports robust decision making, which highlights need to adopt time-varying parameters in modeling reduce degradation. Many existing studies model as functions physically based covariates; however, a major challenge remains finding effective information control large uncertainties that are linked additional within functions. This paper formulated for lumped explicit temporal...

Inter-basin water transfer project is an effective engineering countermeasure to alleviate the pressure of supply in water-deficient areas and balance uneven distribution resources. To assess impacts inter-basin projects on optimal resources allocation, integrated management framework proposed, applied middle lower reaches Hanjiang River Basin China. Firstly, future demands are analyzed as inputs. Then, a multi-objective allocation model formulated mitigating negative downstream quantity...

Abstract. Understanding the propagation of prolonged meteorological drought helps solve problem intensified water scarcity around world. Most existing literature studied from one type to another (e.g., hydrological drought) with statistical approaches; there remains difficulty in revealing causality between and potential changes catchment storage capacity (CWSC). This study aims identify response CWSC by examining hydrological-model parameters after events. Firstly, temporal variation a...

In this study, experiments were conducted on soil samples collected from depths of 0–15 cm, 15–30 and 30–50 cm at the National Long-term Scientific Research Base for Comprehensive Management Rocky Desertification in Wuling Mountains. The aim was to determine physicochemical indexes explore nature spatial heterogeneity planted mixed forests within rocky desertification area Mountain. Various analytical methods employed, including descriptive statistical analysis, correlation analysis...

Abstract. Studies on the hydrological response to continuous extreme and asymptotic climate change can improve our ability cope with intensified water-related problems. Most of literature focused runoff change, while neglecting impacts potential variation in active catchment water storage capacity (ACWSC) that plays an essential role transfer inputs runoff. This study aims systematically identify ACWSC a long-term meteorological drought change. First, time-varying parameter is derived...

MOPEX catchments across the continental United States. Understanding patterns of temporal variation Catchment Water Storage Capacity (CWSC) under changing environments supports superior hydrological predictions. Extensive literature usually assumed scale CWSC was equal to time adopted model. However, this assumption may be doubted as these two scales inconsistent. This study focused on combined impacts different and function forms prediction climate change. The time-varying GR4J model...

Abstract. Understanding the propagation process of prolonged meteorological droughts (i.e., decade) helps solve problem increasing water scarcity around world. Historical literature studied between different drought types (e.g., from to hydrological drought) with mainly statistical approaches, however, little attention has been paid causality potential changes in Catchment Water Storage Capacity (CWSC) where latter plays a critical role catchment response behavior former. This study used...

Abstract. Studies on the hydrological response to continuous extreme and asymptotic climate change can improve our ability cope intensified water-related problems. Most of existing literature focused runoff different patterns, while neglected impacts by potential variation in catchment water storage capacity (CWSC) that plays an important role transfer input runoff. This study aims identify CWSC long-term meteorological drought systematically. Firstly, time-varying parameter is derived...
