This study used trend, correlation, and wavelet analysis to characterize Lake Chad (LC) level fluctuations, river discharge, El Niño Southern Oscillation (ENSO), and precipitation regimes and their interrelationships. Linear correlation results indicate a negative association between ENSO and LC level, river discharge and precipitation. Trend analysis shows increasing precipitation in the Lake ...

Abstract Lakes help increase the sustainability of natural environment and decrease food chain risk, agriculture, ecosystem services, leisure recreational activities locally globally. Reliable simulation monthly lake water levels is still an ongoing demand for multiple environmental hydro-informatics engineering applications. The current research aims to utilize newly developed hybrid data-inte...

35 Abstract: We reconstructed the late-Holocene surface-moisture history and vegetation dynamics of a raised bog in Michigan using testate amoebae, peat humification, pollen, stomata and plant macrofossils. Our primary objective was to compare bog palaeohydrology with the water-level history of Lake Michigan, and to regional and local vegetation changes. Hydrologic histories inferred from testa...

Lake water levels fluctuate due to both natural and anthropogenic influences. Climate change can alter precipitation, driving fluctuations in lake levels. Extreme cause flooding, shortages, changes quality ecosystems, as well affecting fisheries tourism. Despite the need predict future water-level rises, especially context of climate change, long-term hydrological studies are scarce. Here, we a...

The ongoing changes affecting Lake Urmia (NW Iran) are revealed by the lake water level decrease (~7 m in last 20 yr) that was attributed to natural and anthropogenic causes but exact impact of these factors on state is still not identified. Indeed, lack detailed record environmental evolution past limits understanding actual future processes. Our project aims obtain a high-temporal resolution ...

Exploitation of freshwater resources is having catastrophic effects on the ecological dynamics, stability, and quality of those water resources on a global scale, especially in arid and semiarid regions. Lake Kinneret, Israel (the Biblical Sea of Galilee), the only major natural freshwater lake in the Middle East, has been transformed functionally into a reservoir over the course of approximate...

Streamflow, suspended sediment transport and meteorological variables at two elevations were measured through the 1990-1992 field seasons at Lake C2, northern Ellesmere Island, as part of the Taconite Inlet Lakes Project. The objectives were to determine the extent to which suspended sediment flux responded to climatic variability, and to ascertain which meteorological variable was most strongl...

Floodplain lakes and associated wetlands in tropical dry climates are controlled by pronounced and severe seasonal hydrologic fluctuations. We examined the plant community response to a bimodal flooding pattern in the Zapatosa Floodplain Lake Complex (ZFLC), Northern Colombia. We measured floristic and quantitative change in four sampling periods emphasizing seasonal differences in plant abunda...
