Over the past 15 years I have been involved extensively in the development or modification of hydrologic modeling codes. Some of these codes include UZF-RT3D, RT3D-OTIS, and SWAT-Salt. Two of the principal codes are SWAT-MODFLOW and SWAT+, as described below.
SWAT-MODFLOW
We developed the coupled groundwater-surface water hydrologic model by linking the SWAT watershed modeling code with the MODFLOW groundwater modeling code. The modeling code also simulates the fate and transport of nutrients (nitrogen, phosphorus) in the coupled system. The open-source code (Fortran), example models and datasets, and tutorial are available on the SWAT model website here.

SWAT+ with the gwflow module
The SWAT+ modeling code is the new, re-structured version of the SWAT watershed modeling code. Within this new code, we have developed the gwflow (groundwater flow) module that simulates groundwater storage, groundwater flow, and groundwater exchange with land surface and surface water features in a physically based spatially distributed manner. The open source code can be found in the official SWAT+ code here. Tutorials and example datasets can be found here.
