Hydrology & River Engineering
Cost-effective and sustainable river engineering solutions.
Our team have the expertise to deliver cost-effective and sustainable river engineering solutions that protect people and property while recognising ecological, social and cultural values. We offer specialist advice on erosion and sediment management through the complete project lifecycle which recognises our changing physical environment.
Services that we provide:
- Design of river engineering works including diversion channels, spillways, erosion protection and stopbanks
- Erosion and sediment control plans, gravel-bed river management, reservoir sedimentation, bridge scour and design of protection works
- Analysis and design of hydraulic structures including culverts, weirs, intakes, fish passes, energy dissipation and detention dams
- Design of irrigation systems including canals, check structures, pumps and storage reservoirs
- Catchment management plans including hydraulic and hydrological modelling, flood hazard mapping and assessment of climate change images
- Preparation of drawings, specifications and contract documents and construction supervision
- Project management of multi-disciplinary, multi-agency teams to deliver sustainable solutions for stakeholders
- Hydrological catchment modelling and assessment
- Open channel hydraulics assessment, including intake structures, constrictions, stop banks and culverts
- Resource consent application preparation
- Hydrogeological and hydrological assessment
- Assessments of Environmental Effects
- Expert assistance for consent hearings

Invercargill
Ramon is a Chartered Professional Engineer with 30 years of experience in civil engineering, primarily in the areas of river engineering/flood management and geotechnical engineering. That’s mainly been in Aotearoa but includes working in Australia, Indonesia and the UK. He is a member of Engineering New Zealand and the Rivers Group and is a member of the NZ Society on Large Dams (NZSOLD) management committee.
His experience encompasses both broader management approaches/ strategy development for river systems as well as the technical and practical/operational aspects. That encompasses modelling (physical scale and computational) and gravel/sediment transport to the design and construction of stopbanks, training structures, weirs/ drop structures and spillways. Ramon is also an experienced assessor of irrigation and detention dams.
