Hydrographic Survey Services

At Cinquini & Passarino Inc., we provide quality hydrographic survey services for virtually all marine and fresh environments. In the past, many building projects were constructed based on convenience, without consideration of the environmental factors like wave height or changes in water depth. This can cause countless problems. A hydrographic survey is essential for location and design considerations. By using hydrography, you can determine the optimal location for building projects and ensure they’re free of major maintenance issues.

Hydrography is the science of measuring and mapping the physical features of the land around and below the surface of the water. It can also be used to study the movement, distribution, and quality of the water, as well as oceanographic conditions. Our hydrographic surveying services can be used to fit a wide span of projects where in-depth knowledge of the physical environment near or in a body of water is necessary.

For example, we can use hydrographic surveying to help reservoir owners get accurate capacity numbers for their lakes. In this case, we would typically use multibeam sonar to produce a full coverage map of the water depths. We would also collect Lidar topographic elevations along the shoreline to merge with the water depth data. After combining the data from both, we can create a high-resolution model of the capacity of the lake. We can also determine the reservoir’s total capacity at any water level or analyze the different layers of sediment.

Hydrographic surveying can also be used for

  • Planning construction of piers, dams, and harbors
  • Tidal datum reckoning studies
  • Acoustic doppler current profiler studies
  • Dredge plume monitoring
  • Characterizing the wave climate in coastal or high-energy surf zones
  • River and creek high flow monitoring
  • State discharge rating table development
  • Marsh plain Sediment Evaluation Table (SET) installation and monitoring
  • River and creek bed bedload sampling

We utilize the latest state-of-the-art technology for our hydrographic surveying services. Our multidisciplinary team of hydrographers, land surveyors and cartographers are highly skilled. Besides hydrography, we also provide complete land surveying services. We offer GIS mapping, aerial topography, and more. We typically serve the greater Bay Area, although we have provided our surveying services in various locations across the nation. We have offices in Santa Rosa, Healdsburg, and Oakland to assist you with your projects. If you’d like to learn more about our services, contact us at 707-542-6268.
