Surface water browning, the result of increasing concentrations dissolved organic matter (DOM), has been widespread in northern ecosystems recent decades. Here, we assess a database 426 undisturbed headwater lakes and streams Europe North America for evidence trends DOM between 1990 2016. We describe contrasting changes (decelerating) (accelerating), which are consistent with solubility responses to declines sulfate deposition. While earlier (1990-2004) were almost entirely related...
Seasonal climate forecasts produce probabilistic predictions of meteorological variables for subsequent months. This provides a potential resource to predict the influence seasonal anomalies on surface water balance in catchments and hydro-thermodynamics related bodies (e.g., lakes or reservoirs). Obtaining impact discharge temperature) requires link between models simulating hydrology lake hydrodynamics thermal regimes. However, this remains challenging stakeholders scientific community,...
Abstract Catchment‐scale water quality models are increasingly popular tools for exploring the potential effects of land management, use change and climate on quality. However, dynamic, catchment‐scale nutrient in common usage complex, with many uncertain parameters requiring calibration, limiting their usability robustness. A key question is whether this complexity justified. To explore this, we developed a parsimonious phosphorus model, SimplyP, incorporating rainfall‐runoff model...
Abstract. Freshwater management is challenging, and advance warning that poor water quality was likely, a season ahead, could allow for preventative measures to be put in place. To this end, we developed Bayesian network (BN) seasonal lake prediction. BNs have become popular recent years, but the vast majority are discrete. Here, Gaussian (GBN), simple class of continuous BN. The aim forecast, spring, mean total phosphorus (TP) chlorophyll (chl a) concentration, colour, maximum cyanobacteria...
Abstract. Despite high potential benefits, the development of seasonal forecasting tools in water sector has been slower than other sectors. Here we assess skill for lakes and reservoirs set up at four sites Australia Europe. These consist coupled hydrological catchment lake models forced with meteorological forecast ensembles to provide probabilistic predictions anomalies discharge, temperature ice-off. Successful implementation requires a rigorous assessment tools' predictive an...
The European Union Water Framework Directive (WFD) requires Member States to set water quality objectives and identify cost-effective mitigation measures achieve "good status" in all waters. However, costs effectiveness of vary both within between catchments, depending on factors such as land use topography. aim this study was develop a cost-effectiveness analysis framework for integrating estimates phosphorus (P) losses from land-based sources, potential abatement using riparian buffers,...
There is a growing understanding of the role that bedrock weathering can play as source nitrogen (N) to soils, groundwater and river systems. The significance particularly apparent in mountainous environments where fluxes be large. However, our relative contributions rock-derived, or geogenic, N total supply watersheds remains poorly understood. In this study, we develop High-Altitude Nitrogen Suite Models (HAN-SoMo), watershed-scale ensemble process-based models quantify sources,...
The cost-effectiveness of six edge-of-field measures for mitigating diffuse pollution from sediment bound phosphorus (P) runoff temperate arable farmland is analysed at catchment/field scales. These were: buffer strips, permanent grassland in the lowest 7% fields, dry detention bunds, wetlands, and temporary barriers such as fences. Baseline field P export was estimated using coefficients (low risk crops) or a modified Universal Soil Loss Equation (high crops). impact simple equations. Costs...
Across the EU, programmes of measures have been introduced as part river basin management planning a means tackling problems diffuse pollution from agriculture. Evidence is required to demonstrate effectiveness these and with this overarching objective, monitoring an agricultural catchment in Eastern Scotland was initiated 2007. As precursor evaluating effect new it essential understand how other factors, including hydrology land use changes, could influenced water quality. This study...
Abstract Variability in riverine flow regimes is important for aquatic biodiversity. However, across the globe, management of water resources has altered natural dynamics. We explored relationships between regime (calculated from 3 years' daily averaged discharge), and chemistry, benthic algae, as well macroinvertebrate datasets 64 sites Germany Norway. To deal with multicollinearity while maintaining interpretability, we performed principal component (PC) analyses each dataset country...
Abstract. The Mobius model building system is a new open-source framework for fast and flexible environmental models. makes it possible researchers with limited programming experience to build performant models potentially complicated structures. can be easily interacted through the MobiView graphical user interface Python language. was initially developed support catchment-scale hydrology water-quality modelling but used represent any of hierarchically structured ordinary differential...
