“…This indicator describes how the coastline is similar to a circle. A bigger number means that shoreline is more varied and that the interface between the water and the surrounding land is more significant (Moses et al 2011). Both subfossil and contemporary vegetation are typical of humic lakes, while the floating mat comprises two well-developed zones-quaking and firm.…”

The long-term development of three humic lake ecosystems in Poland was investigated through palaeoecological analyses of sediment cores. These wetland records spanning the Holocene were analyzed for plant macroremains, degree of peat decomposition, sediment geochemistry along with radiocarbon dating. Morphological characteristics of the catchments and data on contemporary water quality and management approaches were integrated. Our research on the palaeoecology of humic lakes suggests two main states: humic and eutrophic-humic. Of the lakes studied, only one consistently presented features typical of the humic type. The other two showed various states, and dynamic patterns of transformation. The results indicate that these systems can change from humic to eutrophic-humic, and back again, in response to catchment-linked factors, climatic change and human impact. Thus determination of uniform pattern in the development of humic lakes is questionable. This suggests that a reassessment of brown water lakes is necessary.

“…Terrestrial lakes are an important component of global and regional water cycles since they contribute the most to, and are very sensitive indicators of, worldwide nonfreezing lake water storage [1]. Conventionally, the accurate calculation of lake water storage or volume relies on the correct mapping of lake bathymetry, which is the key parameter for lake morphology study [1][2][3][4]. However, in situ mapping of lake bathymetry is costly and labor intensive [5].…”

The availability of lake bathymetry maps is imperative for estimating lake water volumes and their variability, which is a sensitive indicator of climate. It is difficult, if not impossible, to obtain bathymetric measurements from all of the thousands of lakes across the globe due to costly labor and/or harsh topographic regions. In this study, we develop a new digital lake bathymetry model (DLBM) using the step-wise water recession method (WRM) to generate 3-dimensional lake bathymetric maps based on the digital elevation model (DEM) alone, with two assumptions: (1) typically, the lake’s bathymetry is formed and shaped by geological processes similar to those that shaped the surrounding landmasses, and (2) the agent rate of water (the thickness of the sedimentary deposit proportional to the lake water depth) is uniform. Lake Ontario and Lake Namco are used as examples to demonstrate the development, calibration, and refinement of the model. Compared to some other methods, the estimated 3D bathymetric maps using the proposed DLBM could overcome the discontinuity problem to adopt the complex topography of lake boundaries. This study provides a mathematically robust yet cost-effective approach for estimating lake volumes and their changes in regions lacking field measurements of bathymetry, for example, the remote Tibetan Plateau, which contains thousands of lakes.

“…This map represents an important tool for water quality modeling proposes due to it is highly relation to the reservoir hydrologic/hydrodynamic regime (Moses et al, 2011). Along with meteorological and hydrodynamic data and water quality parameters, it helps to determine the hydrodynamic behavior of the reservoir, improving the knowledge of vertical mixing processes, stratification and reaeration.…”
