Our Services

Environmental Monitoring
We provide independent environmental monitoring, survey and hydrographic services, tailored to your requirements, across the water resources sector.
Flexible and mobile, we cover all regions of New Zealand, and almost anywhere else globally.
Geospatial and GIS
We can obtain detailed bathymetric surveys using our own remote survey boat, aerial photogrammetry, vegetation and soil moisture mapping utilising the latest drone technology, and provide the knowledge and expertise to interpret, display and tie all this information together as required.
Providing vital information for the water resources industry, from power generation through to mining, Smith Hydro’s Geospatial expertise can help you move things forward.


Catchment Hydrology
We can help with most things water. From catchment yield analysis, residual flow assessment, dam reservoir sizing and assessment of effects, through to detailed catchment rainfall-runoff modelling, forensic hydrology, climate change effects and flow regime simulation pre and post-development.
Servicing the entire water resources industry, from on-the-farm resource consent compliance through to detailed environmental impact assessment of large, complex projects.
Flood Risk Assessments
We can provide flood frequency analysis, design storm and flood estimation, flood routing and detailed hydraulic modelling and dam break assessments, in addition to flood plain mapping and flood mitigation design.
Hydraulic modelling of complex water resource challenges, from scour potential at bridge piers, through to fish screen design and conveyance optimisation, Smith Hydro can help with your next challenge.
