Dear Swan users, In my SWAN simulations, the directional spreading parameter (DSPR) seems to be important for the boundary wave conditions. However, the data available to me are limited to Hs, TMM10, mean wave direction, wind speed, and wind direction. Since DSPR cannot be directly derived from these bulk parameters, I would like to ask whether it should be estimated using assumed values. If so, what criteria are typically used in practice (e.g., wind–wave alignment or wind-sea versus swell conditions), and are there commonly accepted reference ranges for DSPR? Any guidance would be appreciated. Best regards, Sihyeon |
