SOFTWARE REVIEW by Robert H.Prucha

The MIKE SHE code is a powerful, physically-based, distributed parameter, fully integrated code for three-dimensional simulation of hydrologic systems. It has been successfully applied at multiple scales, using spatially distributed, continuous climate data to simulate a broad range of integrated hydrologic, hydraulic and transport problems in humid as well as more arid areas. For example, in the U.S., it has been used extensively in South Florida on Everglades Restoration projects, in Colorado, at Rocky Flats (a former DOE nuclear manufacturing facility) and in the Black Mesa basin of northeastern Arizona.

MIKE SHE 2003 was developed by DHI Water and Environment (www.dhi.dk). It was originally developed as 'SHE' along with the British Institute of Hydrology and SOGREAH (France). In the 2003 version, all major hydrologic flow processes are dynamically coupled, including 2-D overland flow, 1-D channel flow, 3-D saturated zone flow, 1-D (Richard's based) unsaturated zone flow, snowmelt and evapotranspiration. Overland flow utilizes DEMs, while channel flow is simulated through the MIKE 11 code, which has extensive capabilities including, user-defined regulating structures, water quality and sediment transport, and a morphological module. It is also capable of simulating integrated advective-dispersive transport, sorption, biodegradation, geochemistry (including PHREEQC), and macropore flow, generally applicable for most hydrologic, water resources and contaminant transport applications. In contrast to similar codes, MIKE SHE utilizes rigorous physical flow equations for all major flow processes, but also permits more simplified descriptions.

MKE SHE has undergone limited verification (www.integratedhydro.com/reviews.html) to test its ability to simulate single component processes and some of their interactions. Though sophisticated and flexible, its ability to simulate evapotranspiration and stream-aquifer interactions could be improved. Verification emphasized that development and calibration requires a systematic approach and careful consideration of scale-dependent integrated processes. Developing more complex, larger-scale integrated models requires specialized skills and a substantial investment in time.

The graphical interface is significantly improved in the 2003 version, offering a dynamic navigation tree, dynamic dialogs, and limited on-line documentation, and notably improved output animation capabilities. It seamlessly links with Arcview shape files and has well-organized spreadsheet-graphical functionality for ease in editing spatial and temporal input.

DHI offers the full version of MIKE SHE for about $10,000, though simpler versions are less expensive and specialized add-on modules increase the price.
