River Teifi Temporal Analysis Report

Adroddiad Dadansoddi Amseryddol Afon Teifi

This report analyses water quality parameters, including phosphate levels, across multiple sampling sites along the River Teifi over time. It provides a comprehensive view of temporal variations for parameters such as Temperature, pH, Electrical Conductivity, Dissolved Oxygen, and Phosphate concentrations. Seasonal patterns and trends are highlighted, helping to understand changes in water quality across different periods of the year.

Mae'r adroddiad hwn yn dadansoddi paramedrau ansawdd dŵr, gan gynnwys lefelau ffosffad, ar draws safleoedd samplu lluosog ar hyd Afon Teifi dros amser. Mae'n darparu golwg gynhwysfawr o amrywiadau amseryddol ar gyfer paramedrau fel Tymheredd, pH, Dargludedd Trydanol, Ocsigen Tawdd, a chrynodiadau Ffosffad. Tynnir sylw at batrymau a thueddiadau tymhorol, gan helpu i ddeall newidiadau mewn ansawdd dŵr ar draws gwahanol gyfnodau o'r flwyddyn.
