Use of FEMWATER for dewaterring


Recommended Posts

Hi All,

I have a project that we are going to construct a regional model for a bedrock system to evaluate dewatering and groundwater/surface water (ponds, rivers, streams) interaction. I am interested in knowing the capabilities and limitations of FEMWATER for this type of model and if the output from GMS is similar with FEMWATER as it is with MODFLOW.

The other model we are looking at is Feflow. If anyone can provide a comparison (limitations/benefits) of the two models that would be great.

Thanks in advance: Greg

Thanks Simon,

Just for clarification I am not looking at modeling surface water, I am just trying to model groundwater interaction w/ surface water. Similar to what MODFLOW can do. Based on what you say, FEMWATER is not capable of simulating groundwater discharge to a river or a pond, is this correct. Is there other boundaries that you can use to mimic a surface water body?

Thank you

I am not very familiar with MODFLOW. But FEMWATER has several types of boundary conditions, some of which can be used to simulate groundwater discharge to a river or pond. I imagine you would use a specified head boundary, and you would need to provide the specified head for the surface water body.

When you said "interactions" I assumed you would want to calculate changes in the surface water body due to groundwater.
