It’s now possible to model water quality when using flood codes to simulate floodplain inundation. Flood code cells can exchange solutes with overland flow and groundwater (saturated zone). Using this feature, users can take advantage of the simplicity of using flood codes in water quality studies, reducing model setup and run times and increasing project efficiency.

MIKE SHE’s new lightweight result files (.sheres) help users save space when running operational systems with frequent hotstart simulations by containing only the data required for subsequent simulations.

Save time and improve your modelling workflows using MIKE Zero’s upgraded editors and viewers. Take advantage of new keyboard shortcuts and themes, improved tabbing, tear off and cascade functionality plus easier access to User Guides and Scientific Documentation.

With easy access to processed data files directly from the Results Viewer, additional loading and configuration steps are eliminated. Plus, MIKE SHE users can take advantage of more options here for inspecting preprocessed data compared to the Grid Editor, which is optimised for editing not viewing.

MIKE Zero, DHI’s fully Windows integrated graphical user interface, is now better than ever! Enjoy easy access to new MIKE Cloud applications and Cloud-enhanced functionality, plus an extended set of MIKE tools within theme-based (rather than product-based) interactive workflows. Ensure important model components such as sources and structures stay at the forefront with a new interactive, customisable floating mapping window. Lastly, the updated tabbing functionality will help you work in a more organized and efficient manner.

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.
