Question:
When using the estuarine model should I be using the estuary width and depth at the point of discharge or should it be the maximum width and maximum depth?

Answer:
_Good question ... we may have added - should it be the assessment site or should it be the average values for the estuay between the point of discharge and the assessment site to your options. We would probably not suggest using the maximum values for the estuary although the minimum values would result in a conservative assessment it that is your aim. Unfortunately there appears to be no guidance on this in the IAEA SRS-19 document.

For flow rate the SRS-19 text on estuarine model (see Section 4.2.2) states that the flow rate for the river upstream of tidal limit should be used._
