Development of a Liming Prediction Model for Llyn Brianne

<jats:title>ABSTRACT</jats:title><jats:p>This paper describes a model which was developed to simulate the effect of automated liming on the quality of a Welsh lake (Llyn Brianne) and its outflow river. The objective was to model the amount of lime required to dose the input streams under a variety of conditions. It was concluded that it would be feasible to install automatic‐dosing equipment on the two input streams to deliver sufficient lime to ensure that the pH of the lake and water downstream was controlled at a pH value of 6.0 or greater, thus stabilizing water quality for fish and other aquatic biota.</jats:p>
