Late Holocene environmental history of Dojran, Macedonia: Investigating the interplay of imperial dynamics and climatic change

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT This study presents a high‐resolution, multi‐proxy reconstruction of environmental and land‐use change from Lake Dojran over historical times (last 2500 years), combining pollen, biomarkers, radiocarbon dating, Ottoman taxation records and other historical data.

Uncertainty in aquatic greenhouse gas flux estimates arises from subjective processing of floating chamber time series

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Accurate quantification of greenhouse gas (GHG) fluxes from aquatic systems is essential for constraining regional and global carbon budgets. Closed floating chambers are widely used to measure carbon dioxide (CO2) and methane (CH4) fluxes at the water–air interface, yet large uncertainties persist due to subjective processing of chamber time ...

Impact of potential climate change on plant available soil water and percolation in the Upper Danube basin [PDF]

open access: yes, 2010
The soil root zone of the land surface provides plants with water for transpiration and therefore biomass production and its excess water percolates downwards and ultimately recharges the groundwater aquifers.

A framework to evaluate and identify development requirements for land‐surface models at km‐scale resolution: Application to a semi‐arid and mountainous region

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
This article provides a first evaluation of land‐surface models at the km‐scale resolutions at which they are used in weather and Earth‐system models. At these resolutions, the lateral transfers of water that organize landscapes play an important role in predicting evaporation correctly. Riparian processes and human water management for irrigation need

Redistributive effects of unsteady flow regimes downstream of reservoirs

open access: yesRiver, EarlyView.
Abstract Understanding unsteady flow regimes in river channels downstream of a reservoir, is essential for predicting and regulating water level and flow velocity in the lower basin. Using hourly observations of discharge and water level at Xiangjiaba Station from 2018 to 2022, an evaluation indicator was proposed to analyze unsteady flow regimes ...

Evaluating the Role of Social Capital for the Design of Sustainable River Governance Strategies: The Case of Tagus River

open access: yesSustainable Development, EarlyView.
ABSTRACT This study examines the role of social capital in designing and implementing more effective governance strategies to improve the state of the Tagus River's significantly deteriorated middle reach (Spain). We employed social network analysis (SNA) to evaluate the bonding, bridging and linking social capital and the quality of stakeholder ...

Trace Element Contamination in Top Predatory Elasmobranchs From the Southern Black Sea: Implications for Ecosystem Health and Risk Assessment

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Environmental pollution resulting from the rapid increase in human population, urbanization, intensive use of chemicals in agriculture, and industrial development has reached a level that threatens natural life today. Trace elements are one of the most important factors causing significant levels of pollution in the environment and are added ...
