Hi, I have started on using the GWB for modeling the simple evaporation of rainwater sample. I am using average rainwater values obtained from a site in nevada for the modeling and i use the "react - XXX.XXXg" for the evaporation. the problem i am facing is how to input the NH4+ values. Almost all rainwater samples have high NH4+ values which can be ignored and to based on the littel knowledge i have on GWB it lets me to swap NH4+ for NO3- which i dont want as i have separate NO3 values too. Also has there been studies on modeling the evaporation of rainwater to minerals using GWB or other softwares? thanks Balaji

thanks a lot Tom!

Hey all, This is my first time in this forum and i am tryn to get started with the GWB Release 6.0.2. I was wondering as to how GWB can be used to model precipitaion of minerals in an aqueous system containing normal occuring cations and anions. The model i want to do is really basic. I am trying to evporate the water in the aqueous phase and see what minerals precipitate out at different timelines. I also dont know how to substract water from the aqueous (sort of modeling evaporation) system with increasing time adn let the GWB tell me wat minerals precipirate out. thanks
