It is well known that sediment movement is affected by aquatic vegetation under flow and wave conditions. However this impact is not fully understood yet. The aim of this study is to determine the effect of emergent vegetation on suspended sediment flux under wave conditions. In this context, an experimental study was conducted and wave orbital velocities and suspended sediment concentrations are measured through 4 m long emergent reeds under regular waves. Suspended sediment fluxes were calculated and the results of these calculations were evaluated. The results showed that the depth integrated suspended sediment flux were retained 75% to 90% due to vegetation.


Climate change effects on nitrogen loading from cultivated catchments in Europe: implications for nitrogen retention, ecological state of lakes and adaptation

Climate change might have profound effects on the nitrogen (N) dynamics in the cultivated landscape as well as on N transport in streams and the eutrophication of lakes. N loading from land to streams is expected to increase in North European temperate lakes due to higher winter rainfall and changes in cropping patterns. Scenario (IPCC, A2) analyses using a number of models of various complexity for Danish streams and lakes suggest an increase in runoff and N transport on an annual basis (higher during wint...

During the past century, many brackish shallow lakes worldwide have become eutrophic. How the zooplankton have responded to this development is not well elucidated. Here, we analysed the decadal changes (from 1999-2000 to 2017-2018) in zooplankton biomass, body mass, and potential top-down control on phytoplankton during summer in 4 Danish shallow brackish lakes (Lund Fjord, Han Vejle, Selbjerg, and Glombak) subjected to varying degrees of eutrophication. Significant reductions of zooplankton biomass, body ...

Coasts are sensitive and dynamic areas against natural influences such as waves, winds, currents, and tides. Pressure of human activities also accelerate the change of coasts. Climate change and global sea level rise are other factors affecting the coasts. Therefore, the identification and protection of coasts, which are important in terms of socio-economically and natural environment, becomes an important issue. One of the main purposes of this study is to classify Mersin and İskenderun bays coasts accordi...
Trend Analyses of Meteorological Variables and Lake Levels for Two Shallow Lakes in Central Turkey
YAĞBASAN, ÖZLEM; Demir, Vandettin; Yazıcıgil, Hasan (2020-02-01)
Trend analyses of meteorological variables play an important role in assessing the long-term changes in water levels for sustainable management of shallow lakes that are extremely vulnerable to climatic variations. Lake Mogan and Lake Eymir are shallow lakes offering aesthetic, recreational, and ecological resources. Trend analyses of monthly water levels and meteorological variables affecting lake levels were done by the Mann-Kendall (MK), Modified Mann-Kendall (MMK), Sen Trend (ST), and Linear trend (LT) ...
Wind and swel wave climate for the southern part of Black Sea
Berkün, Uğur; Yalçıner, Ahmet Cevdet; Department of Civil Engineering (2007)
The swell waves which are an important component of wind generated waves have significant effects on small craft and fisheries. The swell wave climate has an important role in the design and operation of fishing harbors and harbors for small craft. Despite this fact the swell wave climate is not well known for the Turkish coasts. The purpose of the present study was to identify the swell wave climate along the Black Sea coastline of Türkiye. For this purpose wind and swell wave data for a 65 months period i...
