“…A similar pattern is predicted for shallow tropical lakes outside of the Pantanal, where lakes infill within 10 2 -10 3 years (e.g., Kossoni and Giresse, 2010). The actual sediment accumulation rates in all lakes considered in this study may be higher considering the land use/land cover changes recorded in the tropical lowlands (e.g., Biswas and Dhara, 2019). We can be confident that the rate of accumulation of sediment volume is increasing throughout the lake basins (Bennett and Buck, 2016).…”

Shallow lakes in tropical floodplains provide significant ecosystem services that can be altered by natural and anthropogenic forces. Despite their importance, little is known about the infill patterns and timescales and the magnitude of these changes in tropical floodplain lakes. Here, we present a global meta-analysis of sediment core-derived accumulation rate data for shallow floodplain lakes in tropical lowlands to quantify the timescales of basin infill. Environmental variables (e.g., sediment accumulation rates, bathymetry, surface area) were compiled from the literature or derived from remote sensing imagery, resulting in a database (n = 76 lakes) that includes various lake morphologies. Our results show an exponential increase in sediment accumulation rates in many of these lakes over the past 50 years, which we interpret as a response to growing human populations and deforestation, particularly in topographically steep watersheds with pronounced seasonal rainfall. Over centennial periods, tropical floodplain lakes accumulate sediment faster than many other extratropical lakes. The dataset suggests that complete infill of some tropical floodplain lakes will occur in as little as a few centuries. Our findings also reveal the critical environmental and human factors that influence sediment accumulation patterns and affect ecosystem services in shallow tropical floodplain lakes. These findings have important implications for water and sediment management in low latitude watersheds, many of which are located in densely populated and/or developing nations.

“…[21,22]. The amount of sediment load depends on sediment production by slopes and the river's transport capacity [23][24][25]. Interactions between Hydrographic Network Organization and Morphology: In the Kert watershed, the interaction between landscape morphology and hydrographic network organization is key to understanding the hydrological dynamics of the region.…”

This study investigates the intricate relationship between hydrographic network organization, geological faults, and regional dynamics within the Kert basin in the Eastern Rif region. Through GIS hydrographic analysis, we analyze the impact of the hydrographic network on landscape morphology and hydrological dynamics, emphasizing implications for sustainable water resource management. Results reveal the presence of dendritic and parallel hydrographic networks influenced by geological faults, which guide water flow and shape drainage patterns. Seasonal variations in sediment load show significant transport in September and May, indicating increased torrentiality in upstream areas. Fault structures play a crucial role in landscape formation and water quality, with tectonic movements contributing to the development of reliefs and valleys. Understanding these interactions is vital for developing effective strategies for flood mitigation, ecosystem conservation, and sustainable water supply in the Kert basin and similar regions worldwide.
