Dry season baseflow, but how to determine impact?
I'm looking for some clarification on the link between RIOS and InVEST regarding the objective to improve "dry season baseflow".
I'm looking at a catchment where improvements in baseflow could have impacts on irrigation frequency during the dry season. RIOS can optimize landscape interventions to address baseflow, and recommends assessing the before/after change using InVEST Water Yield model. However, the WY model does not distinguish between surface water, subsurface water, and baseflow.
Naturally, landscape interventions that improve infiltration would likely decrease surface flow (decreasing the catchment WY) and increase baseflow (increasing the catchment WY). Therefore, an increase or decrease in WY tells us nothing about either baseflow or surface flow.
Am I making sense? And has anyone an idea of how to prove impact on baseflow? Thanks in advance for thoughts!
