Shakespeare Creek Culvert Replacement | Whittier, AK
“PND is an exceptional company who can take a conceptual idea and turn it into a reality. They were assigned a task to design a replacement for a failing culvert with an arched bridge in a registered fish stream on a very tight deadline. The team that was assembled got all the necessary permits, design, and construction completed within a three-month period. Their dedication to a quality project that comes in on time and under budget sets them apart from their competitors. PND has demonstrated on numerous occasions how to think outside the box when faced with unknown conditions and can develop a resolution that is cost-effective and practical.”
FAQs
To learn more about PND’s hydrologic and hydraulic services, read our frequently asked questions.
What is the importance of hydrology and hydraulics in construction and engineering projects?
Hydrology and hydraulics are crucial for understanding water flow patterns, designing drainage systems, and protecting structures from erosion.
What are some common applications of hydrology and hydraulics in engineering projects?
These disciplines are most often used in designing stormwater management systems, flood risk analysis, bridge and culvert hydraulic analysis, and erosion protection design.
How does PND approach hydrology and hydraulics in arctic environments?
PND leverages its specialized knowledge, experience, and advanced technology to address the unique challenges of arctic hydrology and morphology, ensuring accuracy and efficacy.
What field study techniques does PND use for hydrology and hydraulics projects?
PND uses advanced techniques such as acoustic Doppler current profilers and conventional flow meters for data acquisition. This is particularly necessary for challenging environments or areas in which historical data are sparse.
What modeling and analysis methods does PND use for hydrology and hydraulics?
We use sophisticated 1D and 2D river models (HEC-RAS, SRH2D, HY-8, and Federal Highway Administration and U.S. Army Corps of Engineers methods) and ice-structure interaction models for more precise project outcomes, especially for flood analysis and river erosion protection.
How does PND ensure its hydrologic and hydraulics solutions’ accuracy?
We rely on our rigorous data collection, advanced modeling techniques, and years of expertise and experience to deliver effective, accurate engineering solutions for our clients.
