“…The early Streeter and Phelps models date to 1925 and were used to develop pollution control strategies in rivers (Wang, Li, Jia, Qi, & Ding, ). These were 1D, steady‐state models used to simulate relationships between pollutants and dissolved oxygen and sediment oxygen demand (Gao & Li, ). With the advancement in computational resources, the 1D models have expanded to 2D and 3D models and include the capacity to simulate other elements (e.g., nutrients and organic chemicals) and effects on biota (e.g., algae, macrophytes, invertebrates, fish, birds, and mammals; Park, Clough, & Wellman, ; Wang et al, ).…”

These were 1D, steady-state models used to simulate relationships between pollutants and dissolved oxygen and sediment oxygen demand (Gao & Li, 2014 reviewed simulated the transport and levels of a range of determinates across the study area (Table A6). For example, nutrients (e.g., nitrates, ammonia, and phosphorus), oxygen (e.g., dissolved oxygen and biological oxygen demand), water temperature, primary productivity (especially chlorophyll a), and dissolved and suspended sediments were modelled for a range of environments.…”

Ecohydrology combines empiricism, data analytics, and the integration of models to characterize linkages between ecological and hydrological processes. A challenge for practitioners is determining which models best generalizes heterogeneity in hydrological behaviour, including water fluxes across spatial and temporal scales, integrating environmental and socio‐economic activities to determine best watershed management practices and data requirements. We conducted a literature review and synthesis of hydrologic, hydraulic, water quality, and ecological models designed for solving interdisciplinary questions. We reviewed 1,275 papers and identified 178 models that have the capacity to answer an array of research questions about ecohydrology or ecohydraulics. Of these models, 43 were commonly applied due to their versatility, accessibility, user‐friendliness, and excellent user‐support. Forty‐one of 43 reviewed models were linked to at least 1 other model especially: Water Quality Analysis Simulation Program (linked to 21 other models), Soil and Water Assessment Tool (19), and Hydrologic Engineering Center's River Analysis System (15). However, model integration was still relatively infrequent. There was substantial variation in model applications, possibly an artefact of the regional focus of research questions, simplicity of use, quality of user‐support efforts, or a limited understanding of model applicability. Simply increasing the interoperability of model platforms, transformation of models to user‐friendly forms, increasing user‐support, defining the reliability and risk associated with model results, and increasing awareness of model applicability may promote increased use of models across subdisciplines. Nonetheless, the current availability of models allows an array of interdisciplinary questions to be addressed, and model choice relates to several factors including research objective, model complexity, ability to link to other models, and interface choice.

“…on seasonality of quality parameters of lake waters has not been presented, as it is irrelevant for this approach. Case study papers, assessing spatial distribution of parameters or modeling approach, often lack seasonal perspective [23][24][25]. This paper focuses on the impact of Lake Bikcze's confluence (inflow-outflow transect) on DO, pH, and chlorophyll-a distribution.…”

Abstract:The role of confluence (flowability) in shaping the concentration of dissolved oxygen (DO), chlorophyll-a (chl-a) and pH was determined using a model approach. The calculations considered both horizontal and vertical variability of parameters. There was a general tendency for the pH and oxygen to increase along the transect connecting the place of surface water inlet, deepest point of the lake basin and the place of water outlet, and the reverse tendency for chlorophyll. The average gradient for particulate radius was calculated as arithmetic mean value of six partial gradients (corresponding to individual depths, every 0.5 m). Values of average gradients indicated high dynamics of DO and pH concentration changes as well as low chlorophyll-a variability. A slight inclination of the final resultant vector gradients of DO and pH from the surface water inlet, deepest point of the lake basin and the place of water outlet transect indicated the dominant role of confluence in these parameters variability (values amounted to 6.08 mg·km −1 and 3.34 pH units·km −1 , respectively). The value of the chlorophyll-a gradient vector (1.86 µg·km −1 ) indicated a slight differentiation of the parameter in the basin, independent of the hydrological conditions. The concentration of chl-a in the polymictic Lake Bikcze resulted from the effect of the limnic conditions; the flowability of the lake was just one of many factors affecting the variability of the parameter.

“…Water quantity and quality modelling using catchment scale, dynamic models has become very popular during past two decades [GAO, LI 2014]. One of the most popular models is Soil and Water Assessment Tool (SWAT) which was applied in Europe across a range of spatial scales: from the whole continent , to largest river basins [ČERKASOVA et al 2016;PAGLIERO et al 2014;PI-NIEWSKI et al 2016], meso-scale catchments [OSTOJ-SKI et al 2014;PINIEWSKI et al 2015] and small catchments [BRZOZOWSKI et al 2011;MARCINKOW-SKI et al 2013;MOLINA-NAVARRO et al 2014; SMA-RZYŃSKA, MIATKOWSKI 2016;ŚMIETANKA 2014].…”

Journal of Water and Land Development. No. 31 p. 97-111. DOI: 10.1515/jwld-2016. AbstractThis study presents an application of the SWAT model (Soil and Water Assessment Tool) in two meso--scale catchments in Poland (Upper Narew and Barycz), contrasting in terms of human pressures on water quantity and quality. The main objective was multi-variable and multi-site calibration and validation of the model against daily discharge, sediment and nutrient loads as well as discussion of challenges encountered in calibration phase. Multi-site calibration and validation gave varied results ranging from very good (daily discharge) to acceptable (sediment, nitrogen and phosphorus loads in most of gauges) and rather poor (individual gauges for all variables) in both catchments. The calibrated models enabled spatial quantification of water yield, sediment and nutrient loads, indicating areas of special concern in terms of pollution, as well as estimation of contribution of pollution from different sources, indicating agriculture as the most important source in both catchments. During the calibration process a number of significant issues were encountered: (i) global vs. local parametrization, (ii) simulation of different pools of water quality parameters in reservoirs and streams and (iii) underestimation of NO 3 -N loads in winter due to farmers practices. Discussion of these issues is hoped to aid SWAT model users in Poland in a deeper understanding of mechanisms of multi-variable and multi-site calibration.
