Wetlands are among the most productive and protective ecosystems on Earth, yet they are also among the most altered. Across the country, decades of land conversion, drainage modifications, infrastructure expansion, and changing hydrologic conditions have disrupted the delicate balance that allows wetlands to thrive. Today, communities, engineers, and environmental planners are increasingly turning toward restoration as a way to rebuild resilience, reduce flood risks, and reconnect natural systems.
But restoring a wetland is not as simple as adding water back to the landscape.
Successful wetland restoration depends on understanding how water moves, where it pools, how long it remains, how groundwater interacts with surface systems, and how changing conditions will influence ecological performance over time. That level of precision requires more than observation alone. It requires advanced hydrologic and hydraulic (H&H) modeling capable of simulating the full complexity of natural systems.
This is where StormWise™, Streamline Technologies’ advanced H&H modeling platform, plays a critical role.
Wetland restoration is the process of manipulating a degraded or converted wetland’s physical, chemical, or biological characteristics to restore its natural ecological functions. In some cases, that means re-establishing a wetland where one previously existed. In others, it involves rehabilitating an existing wetland that has lost functionality due to altered hydrology or surrounding development.
Regardless of the restoration strategy, one factor remains central to long-term success: hydrology.
Water depth, flow timing, infiltration, evapotranspiration, groundwater connectivity, and seasonal fluctuations all determine whether native vegetation can survive, wildlife habitats can recover, and flood storage functions can perform as intended.
StormWiseTM was designed to model exactly these kinds of interactions.
With fully integrated 1D and 2D hydrologic and hydraulic modeling capabilities, StormWiseTM enables engineering professionals, consultants, and water resources managers to simulate how wetlands behave under both existing and proposed conditions. The software combines surface water flow with a rain-on-grid analysis and infiltration via groundwater interactions into a unified modeling environment that helps teams make informed restoration decisions.
One of the most important aspects of wetland restoration is maintaining the proper hydroperiod, or the natural cycle of wet and dry conditions that supports native ecosystems.
Different plant and wildlife species rely on very specific water depth fluctuations throughout the year. If a restored wetland remains flooded for too long, dries out too quickly, or experiences unnatural water level changes, the ecological balance can fail.
StormWiseTM supports continuous simulation modeling using historical rainfall, infiltration, evapotranspiration, and hydrologic data. This allows restoration teams to simulate long-term conditions rather than relying solely on isolated storm events.
By modeling these continuous cycles, engineers can better predict whether hydrologic conditions will sustain a restored wetland for long-term ecological success.
This capability becomes especially important in regions experiencing increased rainfall variabilities, changing groundwater conditions, or more frequent and intense storm events.
Wetlands do not function independently from the surrounding landscape. Their health often depends on complex interactions between surface water and surficial aquifer systems.
StormWiseTM incorporates 2D groundwater modeling alongside surface hydraulics, allowing users to evaluate how groundwater elevations, seepage, and saturation levels influence wetland performance. This dynamic interaction is essential when restoring wetlands near urban development, coastal regions, or areas with high groundwater tables.
The software’s finite element groundwater framework calculates horizontal flow, heads, seepage, and leakage while intersecting directly with the surface water computational mesh. This integrated approach provides a more realistic representation of how restored wetlands will respond over time.
For engineers and planners, this means better insight into how adjacent land development, altered drainage patterns, or even sea-level rise may impact long-term restoration viability.
Wetlands serve as natural flood protection systems by slowing runoff, storing excess water, and reducing downstream flooding impacts. Restoring these functions often requires reconnecting floodplains, adjusting grading, or modifying disconnected flow paths.
StormWiseTM supports these efforts through flexible triangular 2D mesh and advanced surface manipulation tools that allow modelers to simulate how water moves across restored landscapes.
Engineers can test different design scenarios by adjusting elevations, modifying culverts, altering spillway configurations, or reconnecting channels and floodplain areas. The ability to iteratively model these conditions helps teams optimize restoration layouts that balance ecological goals with flood mitigation performance.
For constructed or managed stormwater wetlands, StormWiseTM also allows users to evaluate stormwater attenuation performance by simulating how restored systems slow runoff velocities, store excess water, and reduce downstream erosion risks during heavy rainfall events.
One of the challenges in wetland restoration is communicating how a proposed design will perform over time. Restoration projects often involve multiple stakeholders, regulatory agencies, municipalities, and community members who need to understand complex hydrologic behavior.
StormWiseTM addresses this challenge with powerful visualization and animation capabilities.
Using georeferenced graphics, flexible computational meshes, animated flood inundation mapping, and customizable water surface profiles, StormWiseTM allows users to visualize restoration performance dynamically. Engineers can animate flood extents, track groundwater responses, and overlay results onto 2D or 3D GIS environments to demonstrate how wetlands absorb and redistribute water during storm events.
These visual tools not only improve technical analysis but also support permitting, regulatory review, and stakeholder communication.
As communities continue facing increased flood risks, climate variability, and infrastructure pressures, wetland restoration is becoming an increasingly important component of resiliency planning.
Restored wetlands provide measurable environmental and economic benefits. They absorb stormwater, reduce flood damages, promote groundwater recharge, and strengthen natural infrastructure systems that communities rely on during extreme weather events.
StormWiseTM helps transform these restoration goals into actionable, data-driven solutions.
With over 40 years of advanced hydrologic and hydraulic (H&H) modeling applications, StormWiseTM provides scalable tools for everything from watershed studies and floodplain evaluations to complex surface water-groundwater interaction analysis.
Looking ahead, the role of advanced modeling in wetland restoration will only continue to grow. As restoration strategies evolve toward more integrated, resilient, and nature-based infrastructure solutions, engineers and water resources professionals will need tools capable of simulating increasingly complex environmental systems.
StormWiseTM is positioned to help lead that future, enabling professionals to better understand water, restore critical ecosystems, and build more resilient communities through informed decision-making.
