Abstract. The Centre for Ecology & Hydrology – Gridded Estimates of Areal Rainfall (CEH-GEAR) data set was developed to provide reliable 1 km gridded estimates daily and monthly rainfall Great Britain (GB) Northern Ireland (NI) (together with approximately 3500 km2 catchment in the Republic Ireland) from 1890 onwards. primarily required support hydrological modelling. are derived Met Office collated historical weather observations UK which include a national database rain gauge...
Abstract The notion of convergent and transdisciplinary integration, which is about braiding together different knowledge systems, becoming the mantra numerous initiatives aimed at tackling pressing water challenges. Yet, transition from rhetoric to actual implementation impeded by incongruence in semantics, methodologies, discourse among disciplinary scientists societal actors. Here, we embrace “integrated modeling”—both quantitatively qualitatively—as a vital exploratory instrument advance...
Dissolved oxygen is an influential factor of aquatic ecosystem health. Future predictions deficits are paramount for maintaining water quality. Oxygen demands depend greatly on a waterbody’s attributes. A large sediment–water interface relative to volume means sediment demand has greater influence in shallow systems. In shallow, ice-covered waterbodies the potential winter anoxia high. Water quality models offer two options modelling demand: zero-order constant rate, or diagenesis model. The...
Water quality models are an emerging tool in water management to understand and inform decisions related eutrophication. This study tested flow scenario effects on the of Buffalo Pound Lake—a eutrophic reservoir supplying for approximately 25% Saskatchewan’s population. The model CE-QUAL-W2 was applied assess impact inter-basin diversion after impounded lake received high inflows from local runoff. Three scenarios were tested: continuous flow, immediate release nutrient loading increased, a...
In England and Wales, steroid estrogens: estrone, estradiol ethinylestradiol have previously been identified as the main chemicals causing endocrine disruption in male fish. A national risk assessment is already available for intersex fish arising from estrogens under current flow conditions. This study presents, to our knowledge, first set of catchment-based assessments estrogen future scenarios. The river flows temperatures were perturbed using three climate change scenarios (ranging...
Cattle in-stream activity is potentially an important contributor to water pollution from agriculture. Here we present research on the physical movements of cattle within a stream suspended solid concentrations (SSC). This study used camera surveillance monitor dairy in unfenced reach over four-month period. Results were compared against high-resolution SSC data. Over days that grazed field, 57.9% instances when crossed 25 mg l−1 Freshwater Fish Directive guideline threshold can be...
The water bodies of the Saskatchewan Prairies suffer multiple stressors, and demand for is expected to increase. Water quality models can help evaluate management strategies risks such as climate change. This study assesses impact interbasin transfers on a strategic, eutrophic prairie reservoir that receives poor-quality watershed run-off. A one-dimensional WASP model was used estimate nutrient transformations in along 97 km river channel. then loosely coupled two-dimensional CE-QUAL-W2...
The notion of convergent and transdisciplinary integration, which is about braiding together different knowledge systems, becoming the mantra numerous initiatives aimed at tackling pressing water challenges. Yet, transition from rhetoric to actual implementation impeded by incongruence in semantics, methodologies, discourse among disciplinary scientists societal actors. This paper confronts these barriers advocating a synthesis existing missing links across frontiers distinguishing hydrology...

The prairie waterbodies face a future of warming temperatures and growing water demands. There are increasing concerns about how quality will be affected. Water models an effective tool for examining scenarios conditions that cannot measured directly. This study combined WASP CE-QUAL-W2 to investigate the potential impacts changing flow management climate change in Canadian Prairies. two were loosely coupled simulate strategically managed river-reservoir network. Climate data from Coupled...
A good water quality model needs sufficient data to characterise the waterbody, yet monitoring resources are often limited. Inadequate boundary contribute uncertainty and error. In these situations, same can also be used determine where sampling efforts best concentrated for improving reliability. sensitivity analysis using a one-at-a-time approach on shallow, eutrophic, Prairie reservoir investigates which conditions contributing most variability in model. The results show lake has greater...
