ABSTRACT In recent years, the significant change in runoff–sediment distribution upper Yangtze River has led to an increased sediment contribution from Minjiang Basin (MRB) Three Gorges Reservoir. However, previous studies on load changes MRB have focused mainly annual-scale characteristics, thereby neglecting features driven by floods. Therefore, this study examining flood-event loads based mathematical statistics and comprehensive measurement data. The results indicated that human activities, climate change, seismic events caused increasing trend flood-scale a decreasing lower MRB. modulus at low runoff erosion power levels were greater than those high different abrupt-change stages. During extreme flood events, actual concentration remained below sediment-carrying capacity. This provides novel insights into water resource management during season similar basins.

The ambition of Sustainable Development Goal (SDG) target 6.3 is to improve global water quality by 2030. SDG indicator 6.3.2 monitors progress towards this assessing bodies against 'good' ambient criteria, with nutrients (nitrogen and phosphorus) as part the key metrics. However, large data gaps present a fundamental challenge, especially for Africa on how assess being made respect both current desired future situations. Here, we continental model simulate river sediment load, Total Nitrogen (TN) Phosphorus (TP) loads concentrations. Furthermore, map out critical areas hotspots TN TP pollution period 2017 – 2019 reported in 2020, relation UNEP thresholds used assessment 6.3.2. Utilizing UNEP's which designates body having "good quality" if 80% or more its monitored values meet their targets, estimate that 44% 15% African rivers fail set simulated TN, respectively. When synthesizing 34% do not qualify quality". Geographically, most pronounced nutrient were North Africa, Niger Delta, specific zones Southern Nile basin. These correlate regions characterized high inputs fertilizers manure, wastewater discharge.
