I have a question to ask you. Every time,i run the slamm with the test data. i find there is a date named as "0" ,but the NWI data of this year is the initial data.however the data of the real initial date is not the inital one. what is that? just like below: the NWI data of the Transition Salt Marsh in year '0' is 1.44 hectares,but the one in 1980 is 297.692 hectares. actually, the one in 1980 is 1.44 hectares not in year 0. i wanna know why and what is year '0'?
thank you. have a nice weekend! :)
Date Developed Dry Land Trans. Salt Marsh
0 5103.18 1.44
1980 4985.1848 297.692
2025 4977.1827 110.6415
2050 4968.8413 116.0435
2075 4959.5319 133.7903
2100 4949.708 152.5467
Year 0 represents the initial condition.
Year 1980 represents the model run of the initial condition or the "time-zero" model results. As much as possible you want results for year 0 and "time-zero" to match. This is your way of ensuring the conceptual model is working at your site initially. This comparison is especially important when working with high-vertical-resolution elevation data. An elevation analysis also assists in examining the conceptual model validity for your site.
