Hi,
I'm using SWMM to model a catchment which is located above a longwall mine - the purpose is to assess if observed changes to stream flows in the catchment are climatic or indicative of mining impacts.
Ive established a model which adequately simulates historical streamflows and which successfully uses the aquifers and groundwater flow equation.
I would like to simulate the onset of impacts from mining by increasing the "lower groundwater loss rate" value in the aquifer editor. Is there a way to change such a value mid-simulation?
I have had no success trying to run two separate periods with different "lower groundwater loss rates" for each period as the antecedent conditions for the second (mining) period get mucked up.
Any help would be appreciated
Thanks
Steve
