Resource or Project Abstract

Tackling the problem of eutrophication in fresh waters is at the top of the agenda for the implementation of the Water Framework Directive (WFD) in Ireland. One major pressure is phosphorus loading from diffuse sources. Therefore, there is a need to apply appropriate measures to reduce the diffuse phosphorus pollution at a catchment scale in many river basin districts (RBDs). As implementing these measures disturbs the existing system in the catchment, it is important to be able to predict their impact. This requires the use of a reliable mathematical model to represent the system. Catchment models have become an essential component of sustainable ecosystems modelling and are now used in a much wider range of socio-economic ecologic applications. This study contributes to this subject by developing a state-of-theart adaptive neuro-fuzzy inference system (ANFIS) based on a suite of two new diffuse phosphorus (P) models: (i) the adaptive neuro-fuzzy inference system phosphorus The main activities for the implementation of the Water Framework Directive (WFD) (EEC, 2000) in Ireland are taking place in the context of river basin management projects led by local authorities. The overall objective of these projects is to develop a river basin management system, which will include a programme of measures designed to maintain and/or achieve at least good water-quality status for all waters, and to facilitate the preparations of river basin management plans.

Geographical and Spatial Information Related To This Resource

Description of Geographical Characteristics of This Project or Dataset
The hydrological component used in the temporal scenario of the ANFISP model was extended by incorporating the GOPC model to simulate total P (TP) loads. The application of this model to the Oona Water (Co. Tyrone) catchment in Northern Ireland was used to assess its performance. The catchment is part of an international river basin district managed collaboratively by the Republic of Ireland and Northern Ireland. The catchment area draining through the outlet at Shanmoy is 96 km2. The Brosna river flows in a south-westerly direction to an outlet point at Ferbane (Co. Offaly) which drains 1207 km2 of catchment area.

Lineage information about this project or dataset
The need for computer models as predictive tools to guide the implementation of the WFD in Ireland was the main motive behind this study. A state-of-the-art ANFIS modelling approach was employed to construct a suite of two models to simulate diffuse-source phosphorus pollution at a catchment scale. The first model - the ANFISP model - was designed to simulate continuous discharges and TP loads at a daily time step. The SMAR hydrological model was used for modelling the processes involved in the discharges simulation while the GOPC model was used for estimating the TP loads. The second model is intended to be used as a national phosphorus model (for unmonitored catchments), which estimates the average annual orthoP concentrations, and uses some catchments characteristics as sole inputs. Both models were applied in different study cases and their performance assessed.
Supplementary Information
The authors would like to acknowledge the EPA for the financial support and for making its GIS
database available to the study. Mrs Fiona O'Rourke of the Reporting and Information Section in Office of Environmental Assessment of the EPA is particularly acknowledged for facilitating the
delivery of the GIS data. A number of organisations are also acknowledged for providing the data of the catchments used in the study. These include Teagasc, the Three Rivers Project, and the Lough Derg/ Lough Ree project for providing data from the 84 catchments used in testing the neuro-fuzzy national P mode. The data of the 11 catchments from around the world used in testing the ANFISP model was collected by the Department of Engineering Hydrology of University College Galway through a series of International Flood Forecasting Workshops organised by the department and funded by the Department of Foreign Affairs in Ireland. The Oona Catchment data was collected by Dr Phil Jordan of the University of Ulster in Northern Ireland as part of the LS 2.2. EPA-funded project.
