Abstract. The General Lake Model (GLM) is a one-dimensional open-source code designed to simulate the hydrodynamics of lakes, reservoirs, and wetlands. GLM was developed support science needs Global Ecological Observatory Network (GLEON), network researchers using sensors understand lake functioning address questions about how lakes around world respond climate land use change. scale diversity types, locations, sizes, expanding observational datasets created need for robust community model...
Changes in water temperatures resulting from climate warming can alter the structure and function of aquatic ecosystems. Lake-specific physical characteristics may play a role mediating individual lake responses to climate. Past mechanistic studies lake–climate interactions have simulated generic classes at large spatial scales or performed detailed analyses small numbers real lakes. Understanding diversity change across landscapes requires hybrid approach that couples site-specific with...
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 understanding functioning of ecosystems, filling observation gaps developing effective strategies for water quality management. In this spirit, numerous have been developed since 1970s. We set off explore model by making inventory among 42 modellers, categorizing resulting analysing them diversity. then focus comparing combining...
A feedback between seagrass presence, suspended sediment and benthic light can induce bistability two ecosystem states: one where the presence of reduces concentrations to increase availability thereby favoring growth, another absence increases turbidity reducing growth. This literature review identifies (1) how environmental meadow characteristics influence strength direction (stabilizing or destabilizing) seagrass-sediment-light feedback, (2) this has been incorporated in models proposed...
Abstract The physical dynamics of lake temperature and ice phenology are important in the modelling management temperate aquatic ecosystems. One‐dimensional hydrothermal models have not been well evaluated terms how they simulate particular. We chose four (Hostetler, Minlake, Simple Ice Model or SIM General Lake Model) to test compare their performance water using 16 years field data from Harp Lake, an extensively studied inland south‐central Ontario. Each model produced satisfactory...
Abstract. Oxygen depletion in coastal and estuarine waters has been increasing rapidly around the globe over past several decades, leading to decline water quality ecological health. In this study we apply a numerical model understand how salt wedge dynamics, changes river flow temperature together control oxygen micro-tidal riverine estuary, Yarra River Australia. Coupled physical–biogeochemical models have previously applied hydrodynamics impact upon seasonal hypoxia; however, their...
Abstract. The recycling of organic material through bacteria and microzooplankton to higher trophic levels, known as the "microbial loop", is an important process in aquatic ecosystems. Here significance microbial loop influencing nutrient supply phytoplankton has been investigated Lake Kinneret (Israel) using a coupled hydrodynamic–ecosystem model. model was designed simulate dynamic cycling carbon, nitrogen phosphorus bacteria, zooplankton functional groups, with each pool having unique C...

The significance of the transport nutrient-rich hypolimnetic water via benthic boundary layer (BBL) to productivity Mono Lake was studied using a coupled hydrodynamic and ecological model validated against field data. enabled us differentiate between role biotic components forcing on internal recycling nutrients necessary sustain primary productivity. A 4-year period (1991-1994) simulated in which recycled from zooplankton excretion bacterially-mediated mineralization exceeded sediment...
Estuaries are commonly classified by their flow characteristics and the extent of salt fresh water mixing observed under normal conditions.Highly stratified, "salt-wedge" estuaries characterised a well-defined horizontal halocline, with surface layer forming above saline coastal water.Salt-wedge have large fluvial to tidal ratio typically occur along microtidal coasts where range is less than 2 m.The river in primarily determined turbulent much lesser molecular diffusion (e.g.Masselink...

Abstract. Oxygen depletion in estuarine waters is an important factor governing water quality and ecological health. A complex dynamic balance of physical biogeochemical factors drive the extent persistence hypoxia anoxia making it difficult to predict. An increased understanding effect changing flow regimes temperature on patterns oxygen required support ongoing management. Coupled models have been applied study interaction processes seasonal hypoxia, however, application riverine estuaries...
Estuaries provide an important role in filtering and transforming nutrients transported from catchment areas into marine environments.The dynamic interactions between biophysical processes operating within these systems will influence the vulnerability of estuary to human induced change.Process-based aquatic ecosystem models have been applied coastal estuaries understand how respond anthropogenic nutrient enrichment.These account for system-level responses that are specific estuarine...
Nitrogen biogeochemical response to alternative hydrodynamic regimes in estuaries that experience frequent anoxia has major implications for coastal water quality due the significance of denitrification as a loss pathway bioavailable nitrogen.The efficiency nitrogen removal and storage is dependent on range processes, particular, position salt wedge effect associated regions anoxia.The purpose this study was demonstrate how rapidly shifting oxygen concentrations periodically anoxic Yarra...
