The impacts of extreme climate on summer-stratified temperate lakes: Lake Søholm, Denmark, as an example
The global surface temperature has increased by about 0.74°C over the past 100 years, and the frequency of extreme weather has increased as well. We used the state-of-the-art complex, dynamic, mechanistic mode...

Open AccessQuantifying the streamflow response to groundwater abstractions for irrigation or drinking water at catchment scale using SWAT and SWAT–MODFLOW
Groundwater abstraction can cause a decline in the water table, and thereby affects surface streamflow connected to the aquifer, which may impair the sustainability of both the water resource itself and the ec...

The impact of climate change on a Mediterranean shallow lake: insights based on catchment and lake modelling
Shallow lakes in the semi-arid climate zone of the Mediterranean are sensitive to drought due to the low annual precipitation and high evaporation. Changes in precipitation and temperature as projected by clim...

Forecasting near-future impacts of land use and climate change on the Zilbier river hydrological regime, northwestern Iran
We study and forecast the effects of near-future (NF) land use and climate changes (LUCC) on the hydrological regime (HR) within the Zilbier river basin located in arid and semiarid regions, in the Azerbaijan ...

Testing a New Holistic Management Tool for Nitrogen—Environmental Impacts of Using Manure Acidification in the Danish Agricultural Sector
The fate of anthropogenic reactive nitrogen (N) is often described as a cascade of different nitrogen forms and effects throughout the environment. In order to describe the fate in detail, a holistic approach ...

Major changes in CO2 efflux when shallow lakes shift from a turbid to a clear water state
Lakes can be sources or sinks of carbon, depending on local conditions. Recent studies have shown that the CO2 efflux increases when lakes recover from eutrophication, mainly as a result of a reduction in phytop...

Develo** a New Management Tool—a Holistic View on the Nitrogen Cycle
New agricultural technologies can reduce the emissions of ammonia associated with e.g. manure spreading. Reduced emissions to the atmosphere have the potential to limit the negative impacts of reactive nitroge...

Environmental Impacts—Lake Ecosystems
The North Sea region contains a vast number of lakes; from shallow, highly eutrophic water bodies in agricultural areas to deep, oligotrophic systems in pristine high-latitude or high-altitude areas. These fre...

Open AccessExploring, exploiting and evolving diversity of aquatic ecosystem models: a community perspective
Here, we present a community perspective on how to explore, exploit and evolve the diversity in aquatic ecosystem models. These models play an important role in understanding the functioning of aquatic ecosys...

Application of a Three-Dimensional Water Quality Model as a Decision Support Tool for the Management of Land-Use Changes in the Catchment of an Oligotrophic Lake
While expansion of agricultural land area and intensification of agricultural practices through irrigation and fertilizer use can bring many benefits to communities, intensifying land use also causes more cont...

A community-based framework for aquatic ecosystem models
Here, we communicate a point of departure in the development of aquatic ecosystem models, namely a new community-based framework, which supports an enhanced and transparent union between the collective experti...

Seasonal Dynamics of CO2 Flux Across the Surface of Shallow Temperate Lakes
We used data collected from 1989 to 2009 from 151 shallow (mean depth < 3 m) temperate lakes in Denmark to explore the influence of lake trophic status, surface area and catchment size on the seasonal dynamics...

Open AccessChallenges and opportunities for integrating lake ecosystem modelling approaches
A large number and wide variety of lake ecosystem models have been developed and published during the past four decades. We identify two challenges for making further progress in this field. One such challenge...

The influence of water quality and sediment geochemistry on the horizontal and vertical distribution of phosphorus and nitrogen in sediments of a large, shallow lake
Distinct horizontal water column concentration gradients of nutrients and chlorophyll a (Chl a) occur within large, shallow, eutrophic Lake Taihu, China. Concentrations are high in the north, where some of the ma...
