# HEC-HMS: Basic Student Questions vs MODFLOW

## HEC-HMS: Basic Student Questions vs MODFLOW

(OP)
I have a professor who has asked me to design an example problem for him using HEC-HMS. However I'm having trouble converting his given hypothetical study area originally designed for a MODFLOW cell x cell example into HEC-HMS. I was hoping somebody could help me by clearing up a few questions.

1. Does HEC-HMS use a cell x cell process similar to MODFLOW?
2. Can you adjust ground surface area / aquifer depth in HEC-HMS (say I want to add a ridge to one corner of my study area)?
3. Can you set areas of no flow in HEC-HMS (in modflow this would be similar to setting a cell to 0 for inactive)?

### RE: HEC-HMS: Basic Student Questions vs MODFLOW

modflo is a 3-dimensional groundwater flow model, HMS is a 1-dimensional surface water hydrology model. I'm not sure HMS will do anything you want

### RE: HEC-HMS: Basic Student Questions vs MODFLOW

FLO-2D has a similar finite element approach to two dim surface flow. Could your professor be getting HMS confused with FLO-2D?

### RE: HEC-HMS: Basic Student Questions vs MODFLOW

FLO-2D is also for surface flow. we use it extensively but never for groundwater analysis.

#### Quote (from FLO-2D website)

FLO-2D Basic can tackle many diverse flooding problems including:
River overbank flooding
Unconfined alluvial fan flows
Urban flooding with street flow, flow obstruction and storage loss
Overland progression of tsunami and hurricane storm surges
Watershed rainfall and runoff
Flood insurance studies
Flood mitigation design

again, I dont believe it has the desired capabilities
