“…It has a number of large tributaries, including the Rivers Sowe, Leam, Stour and Alne (Figure 1c). The catchment upstream of Evesham consists of 44% arable land and 30% pasture (Hilton et al, 2002), and contains the city of Coventry, and the towns of Stratford-upon-Avon, Warwick, Redditch and Rugby. Urban and semi-urban land use contributed 14% of the total land cover.…”

“…A geographical information system (GIS) approach was adopted to gain a second estimate of point and diffuse TP inputs at each sampling site (Hilton et al, 2002). Digital representations of the Swale, Frome and Avon catchments were entered into the GIS software (ARC INFO version 7.1.2, Environmental Systems Research Inc., USA), using the Centre for Ecology and Hydrology (CEH), River Centre Line Network (CEH Wallingford, UK).…”

“…The majority of phosphorus transport to catchments, from both diffuse and point sources occurs during short periods of increased discharge (e.g. storm events) [17,18], which demonstrates the importance of high temporal resolution monitoring during such events. Submersible or field-based instrumentation is desirable for monitoring dissolved phosphorus because it eliminates the need for sample collection and storage and, although such instrumentation is available [19,20], it is not used on a routine basis.…”

Abstract:A simple phosphorus (P) transfer model of the Welland catchment, UK, is evaluated against multiple objective functions using a Monte Carlo approach that combines calibration, identifiability, sensitivity and uncertainty analysis. The model is based on simple conceptual rainfall-runoff and river routing components, combined with estimates of the daily nonpoint source load derived from annual landuse-based export coefficients, disaggregated as a function of the runoff. The model has limited data requirements, consistent with data availability, and is parsimoneous with respect to the number of parameters identified through inverse modelling. The best performing parameter sets capture the main aspects of the observed flow and total P (TP) concentrations and provide a suitable basis for a decision-support tool. However, a trade-off is evident between matching the observed flow peaks, flow recessions and TP concentrations simultaneously, highlighting some limitations of the model structure and/or calibration data. Model analysis indicates that daily nonpoint source load cannot be described as a function of near-surface runoff and land use alone, but that other influences, including seasonality, are important. However, further model development to improve performance is likely to introduce additional complexity (in terms of parameter numbers), and hence additional problems of parameter identifiability and output uncertainty, which in turn raises issues of the information content of the available data.
