*3.1. Applying the CE-QUAL-W2*

Water quality models are rarely used in Israel's rivers and streams. Therefore, to show the benefits of the EDSS, a CE-QUAL-W2 model had to be applied for the Yarqon stream. However, the available data on flows, temperature, and water quality in the stream were insufficient to calibrate the model. Therefore, for EDDS demonstration purposes, we applied a non-calibrated model for the stream according to the best data that was available. Although the EDSS cannot supply outputs for decision making under these conditions, we can still demonstrate how the EDSS will assist the YRA if it invests in calibrating a model for the stream.
