MIKE SHE is built on coupled physics-based models for overland flow, unsaturated flow, groundwater flow, and fully dynamic channel flow, including all their complex feedbacks and interactions. MIKE SHE also includes processes such as vegetation-based evapotranspiration, irrigation, snowmelt and water quality.

Groundwater discharge to, and infiltration from, streambeds is critical to understanding integrated catchment hydrology. Such exchanges and feedbacks are important for managing stream-depletion, environmental impacts and natural flood management.
Most rivers, reservoirs and canals are managed to reduce downstream flooding, maximise power generation and control water levels. An optimum control strategy depends on a solid understanding of upstream hydrology.

MIKE SHE is the result of decades of continuous software development. It is designed and used by engineers for practical water resources engineering. MIKE SHE is not an obscure research code. It has a proven track record in thousands of engineering projects in all climates around the world – from the arid western United States and oil sands in Canada to the Okavango Delta in Botswana and water supply catchments of Sydney, Australia.

Let’s face it. Fully integrated models can be complex with confusing data requirements. MIKE SHE’s user interface has been design to remove as much of this complexity as possible. It is flexible enough for the most complex applications, yet remains easy-to-use for simpler ones. MIKE SHE’s workflow and dynamic navigation tree uses logical choices to help you build a model that conforms to your catchment conceptualization. You can speed up your workflow with a full range of pre-processing and post-processing tools.
With MIKE SHE, you have complete control. Each process can be solved at its own spatial and temporal scale. You can select only the relevant hydrological processes and simple or advanced numerical methods with parallelised solvers. All these choices depend on your study goals and the availability of relevant data.
MIKE SHE generates a wealth of insight into where water is and how it moves in your catchment. All these results are automatically created as time varying maps – depth of ponding, ET from roots, snow melt, irrigation deficit, water table elevation, etc.
One of MIKE SHE’s core strengths is its comprehensive and flexible water balance utility. This allows you to really dig into the details of how water moves from rainfall to runoff to infiltration to stream discharge on a local and catchment scale. In a fully integrated model, these processes often have surprising interactions and feedbacks that can impact planning decisions.
Unsaturated flow is a central process in MIKE SHE. Infiltration drives flooding, actual ET and groundwater recharge. MIKE SHE calculates 1D vertical infiltration based on fully distributed soil properties, land use and vegetation. Moisture transport in the unsaturated zone is highly variable both spatially and temporally, and is controlled by capillarity. For example, vegetation can extract groundwater through capillarity even if the rootzone is well above the water table. At a catchment scale, 1D vertical is far superior to a 3D unsaturated flow calculation due to the vast increase in speed. While detail in the vertical dimension is far more important than lateral unsaturated flow across kilometres.
Groundwater flow is driven by recharge – the amount of infiltration reaching the water table. The amount and timing of recharge depends on rainfall and the depth to the water table, as well as intermediate losses to runoff and ET from the soil, the root zone and the water table. All of these processes can be simulated in MIKE SHE, allowing you to calculate detailed temporal and spatial distribution of recharge to groundwater.
Rainfall drives flooding, obviously. However, the speed, extent, and duration of flooding is often a function of the upstream moisture conditions in the catchment before the event. Looking just at a single rainfall event in isolation of the catchment context may lead to inaccurate conclusions, poor planning and in the worst case inadequate emergency response. MIKE SHE is a continuous, whole-of-catchment model that can even use distributed, radar-rainfall data. You can calibrate the model to both dry and wet season responses, giving you increased reliability during all storm events. MIKE SHE models have been operationalize around the world for on-line, continuous flood forecasting.
Snow melt can dramatically affect the timing and volume of spring runoff. MIKE SHE converts elevation-corrected precipitation to wet and dry snow storage, with subsequent melting a function of air temperature. MIKE SHE’s flexible snow melt module has been used in cold climates around the world for reservoir operation and flood management.
Use MIKE SHE with MIKE ECO Lab to simulate fully integrated fate and transport of multi-species reactive solutes in surface water and the subsurface including interactive decay, sorption, precipitation and selective uptake. For example, clients have used MIKE SHE to study the integrated impact of nutrient application in rural areas on eutrophication of downstream lakes.
You can use MIKE SHE to define risk-based source water protection areas using 3D transient particle tracking in the groundwater. MIKE SHE’s random walk particle tracking module is ideally suited for complex, transient simulations with interacting well fields.
All numerical engines in MIKE SHE are parallelised to make efficient use of available multicore resources. Speed up your workflow with access to a full range of pre-processing and post-processing tools.
