| ABSTRACT: | Trend analysis was carried out on fifteen years of monthly nutrient loads and discharge in the Jordan River at its inflow to Lake Kinneret. Nonparametric tests were used to identify trend. Measurement of trends in this source required removal of the discharge effect. For this purpose two models were used: multiple regression and the conditional joint density function. The reliability and efficiency of the models were examined by a Monte Carlo analysis. Upward trends were found in the loads of Ammonium and soluble Phosphorus, but no change was detected in the other nutrient loads. In the last two years a downtrend was detected in Organic Nitrogen loads. |
