We review the published results on Congo Basin hydrology and summarize historic ongoing research. Annual rainfall is ~1900 mm/yr along an east-west trend across basin, decreasing northward southward to ~1100 mm/yr. Historic studies using lysimeters, pans, models suggest that annual potential evapotranspiration varies little basin at 1100 1200 Over past century, river discharge data have been collected hundreds of stream gauges with recent 96 locations now publicly available.

Abstract Here we show how major rivers can efficiently connect to the deep-sea, by analysing longest runout sediment flows (of any type) yet measured in action on Earth. These seafloor turbidity currents originated from Congo River-mouth, with one flow travelling >1,130 km whilst accelerating 5.2 8.0 m/s. In year, these eroded 1,338-2,675 [>535-1,070] Mt of submarine canyon, equivalent 19–37 [>7–15] % annual suspended flux present-day rivers. It was known earthquakes trigger...
Humid tropical forests play a dominant role in the functioning of Earth but are under increasing threat from changes land use and climate. How forest vulnerability varies across space time what level stress can tolerate before facing tipping point poorly understood. Here, we develop index (TFVI) to detect evaluate global threats time. We show that climate change together with land-use have slowed recovery rate carbon cycling. Temporal autocorrelation, as an indicator this slow recovery,...
Many factories use a variety of colours to enhance product aesthetics, leading untreated wastewater being discharged into natural water bodies. This not only poses threat aquatic life but also endangers human health, causing issues like skin diseases, as some dyes are carcinogenic. Rhodamine B dye (RhB) is commonly used in industries such textiles, paper, etc. study focuses on synthesizing, characterizing, and applying Zeolite/Bi2O3 nanocomposites efficiently remove RhB dye. Nanocomposites...
Gaps in hydrological information of the Congo Basin increase uncertainties understanding hydroclimatic processes basin, and consequently risks associated with decision making for major water resources development plans. There is also uncertainty about predictions future climate land use change. These challenges make it essential to explore possible approaches close gaps. Some gaps can be filled using simulation models, which if they prove practical, established available data, but generate...
Although the Congo Basin is still one of least studied river basins in world, this paper attempts to provide a multidisciplinary but non-exhaustive synthesis on general hydrology River by highlighting some points interest and particular results obtained over century surveys scientific studies.

Abstract. The African continent is probably the one with lowest density of hydrometric stations currently measuring river discharge despite fact that number operating was quite important until 1970s. This new Database Hydrometric Indices (ADHI) provides a wide range indices and hydrological signatures computed from different sources data after quality control. It includes 1466 at least 10 years daily over period 1950–2018. average record length 33 years, 131 have complete records 50 years....
Abstract. The Congo River basin (CRB) is the second largest river system in world, but its hydroclimatic characteristics remain relatively poorly known. Here, we jointly analyse a large record of situ and satellite-derived observations, including long-term time series surface water height (SWH) from radar altimetry (a total 2311 virtual stations) extent (SWE) multi-satellite technique, to characterize CRB hydrology variability. First, show that SWH multi-missions agrees well with stage at...
Billions of tons hazardous mine waste are stored in thousands tailings storage facilities around the world. These impoundments represent one most important environmental risk factors industrial mining, since occasional spills or dam failures cause devastating impacts on humans and ecosystems, specifically along river corridors. In this study, we developed a satellite remote sensing methodology to assess water quality focusing controversial incident that occurred at Catoca diamond Angola late...
Abstract Large river hydrodynamics studies inform global and regional issues pertaining to biogeochemical cycling, ecology, water availability, flood risk. Such rely increasingly on satellite measurements, but these are limited by resolution, coverage, uncertainty their inability directly measure bathymetry or discharge. We obtain new in situ data covering 650 km of the Congo's main stem, including elusive discharge measurements that complement space‐borne sets. Our key findings relate our...
The Congo River Basin, located in central Africa, is the second-largest river basin world, after Amazon. It has a drainage area of approximately 3.7 M km2 and home to 75 million people. A significant part population exposed recurrent floods droughts, climate change likely worsen these events. Climate studies have so far focused on annual seasonal precipitation, but little attention was paid extreme climatic This study aims assess future changes rainfall-induced flash drought regimes from...

This study aims to establish uncertainty ranges hydrologic indices and provide a basis for transferring from gauged ungauged sub-basins by identifying most influential climate physiographic attributes. Only limited information on individual natural hydrology exists across Basin, limiting application commonly used regionalization approaches prediction sub-basins. uses predictive equations all regions based only aridity...
Global flood models (GFMs) and earth observation (EO) play a crucial role in characterising flooding, especially data-sparse, under-resourced regions of the world. However, validation studies are often limited to handful historic events do not directly assess ability these products simulate hazard—the probability that flooding will occur given location. As result, it is difficult for stakeholders decipher either or observations identify hazard make decisions mitigate flooding. Here, we...

Surface water resources are essential for a wide range of human activities, such as municipal supply, fishing, navigation, irrigation, and hydropower. Their regime is also linked to environmental sustainability, water-related risks, health, various ecosystem services. Global warming expected modify surface availability, quality, distribution therefore affect use productivity well the incidence risks. Thus, it important communities plan adapt potential impacts climate change. The Congo River...
Abstract The processes that occur in wetlands and natural lakes are often overlooked not fully incorporated the conceptual development of many hydrological models basin runoff.

This is certainly case for river basins southern Africa which contain large altered through attenuation, storage slow release within water bodies. Initial modelling studies conducted...
