Riverine Sciences
NV5 Geospatial utilizes a variety of hydrographic survey data inputs (lidar, topobathy lidar, thermal, hyperspectral) in order to build a robust collection of hydrologic models that allows us to understand and communicate complex relationships in the field of hydrology. Our data scientists cover hydrological disciplines that span the entire water usage cycle- from sources, to distribution, to usage.
Flow Delineation
Gain insight into hydrologic processes such as watershed delineation, stream channel determination, paleo-channel identification, and overland flow routing.
Irrigated Landscape Analysis
Analysis of land use, surfaces, and flow in combination with property data can determine the effects of built environments on water usage.
EDH - Elevation Derived Hydrology
We provide a multi-environment process integrating multiple approaches to derive flowlines and hydrologic networks
We work with local experts to refine landscape-specific parameters for refinement and attribution of flowlines. We use a combination of flow direction and accumulation routines along with direct detection of landscape channelization through geomorphon analysis.Â
These two methods (flow accumulation and geomorphons) work in tandem to support derivation of systematically objective and reproducible EDH networks. NV5 Geospatial has utilized these two approaches to optimize the process for hydro-enforcement of false obstructions in the DEM, ensure topologically connected line work, identify commission errors where no surface flow exists, and more accurately estimate headwater initiation in upper reaches.
Heat Source
Understand stream temperature relationships to manage water distribution and aquatic habitat quality. Through hydrographic survey technology, NV5 Geospatial produces informative visualizations of stream temperature methodologies including thermal analyses for river habitat, flow diversion scenarios, sun/shade analysis, and source determination.
