The integration of water management goals in protected wetland areas agriculturally managed an intensive manner recalls the comparison apples (ecological values) and oranges (economic dimension agriculture). Sustainable frequently fails if environmental features are not referred to as ecosystem services quantified economic terms. In our hydrological-economical study on floodplain wetlands located Lower Basin Biebrza Valley, we attempt quantify monetary value storage during flood phenomena...

Consequently, important plant communities riparian wetland were vegetation season (February-September) daily time series (1961-1996). Then, their...

A very low concentration of manganese (Mn) in water is a critical issue for municipal and industrial supply systems. Mn removal technology based on the use oxides (MnOx), especially dioxide (MnO2) polymorphs, under different conditions pH ionic strength (water salinity). The statistical significance impact polymorph type (akhtenskite ε-MnO2, birnessite δ-MnO2, cryptomelane α-MnO2 pyrolusite β-MnO2), (2–9) (1–50 mmol/L) solution adsorption level was investigated. analysis variance...

The ice phenomena are an inherent component of rivers in temperate, continental, and polar climate zones. Evident progress global warming leads to a decrease snow cover on land water bodies, disrupting the stability hydrological cycle aquatic ecosystems. Although common observations indicate disappearance over recent decades, detailed quantitative research is lacking many regions, especially temperate zone. In this paper, were analyzed southern Poland, located upland mountain areas country,...

Large-scale management, protection, and restoration of wetlands require knowledge their hydrology, i.e., the status dynamics groundwater table, which determine evolution wetland ecosystem, its conservation value, possible economic use. Unfortunately, in many cases, hydrological monitoring data are unavailable, resulting search for a proxy average annual depth level (GWL). This study presents an approach to estimating mean GWL peatlands using Bayesian belief network (BBN) model, leveraging...

Modelling groundwater depths in floodplains and peatlands remains a basic approach to assessing hydrological conditions of habitats. Groundwater flow models used compute heads are known for their uncertainties, the calibration these uncertainty assessments parameters remain fundamental steps providing reliable data. However, elevation data determine geometry model domains frequently considered deterministic hence seldom source model-based level estimations. Knowing that even cutting-edge...

Northeast Poland, Biebrza Basin. Studying reference ecosystems and their specific features provides information to be used as background principles for ecosystem management. In the case of riparian wetlands, these are hydrological indicators (such average water levels, flooding extents flood duration) that either criteria conservation or remain easy-to-measure targets habitat restoration. We focused on revealing whether any trends in durations inundation exist within near-natural temperate...

Floods are naturally occurring extreme hydrological events that affect stream habitats and biota at multiple extents. Benthic macroinvertebrates (BM) widely used to assess ecological status in rivers, but their resistance resilience floods medium-sized, temperate, lowland rivers Europe have not been sufficiently studied. In this study, we quantified the effect of a moderate (5-year return period) yet long-lasting unpredictable flood occurred summer 2020 on BM community Jeziorka River central...

Temporal variability of the selected flood parameters in Biebrza River valley The paper presents application hydrodynamic one-dimensional model river flow based on St Venant equations for calculation annual floods characteristics Lower Basin situated Northeast Poland. This was combined with Digital Elevation Model (DEM) determining area flooding, its mean depth and volume. calibrated using measurements extent verified comparing calculated to satellite images. water level values numerical...

Capsule Foraging sites of Aquila clanga compared to pomarina are characterized by a considerably longer duration flooding within the year and higher mean maximum depths flooding. A. is particularly associated with shallow (approx. 20 cm) spring flooding, lasting at least up beginning May (on average 90 days per year). Variation in habitat selection respect water regime might be due different food preferences adaptation landscape differences ranges these two species.

We studied distributions and abundances of macroinvertebrates in relation to hyporheic water exchange (HWE) patterns the upper Biebrza − a small, lowland, low dynamic European river located Northeast Poland.
