Overview
This project evaluates the processes and pathways of phosphorus (P) delivery from agricultural land to water by combining fuzzy modelling and field measures in a range of catchments to predict the delivery of sediment and nutrients to stream channels. The aim of the project is to
- better inform policy decisions and
- investment in mitigation measures at specific sites where the risk of P delivery may be high.
The project combines field and modelling approaches to obtain data on P delivery with which to calibrate the delivery coefficients in our models. The project is linked with
- the PIT project
- the PSYCHIC project
- the BBSRC project on colloidal P losses.
The objective of this project is to maximise the amount of information we can obtain from a minimum range of measurements so that we can improve our model predictions for both data-rich and data-poor situations - the latter being the norm. Such predictions are needed so that we can estimate P delivery to water under different management strategies to better inform policy decisions and investment in mitigation measures at specific sites where the risk of P delivery may be high.
