GIS Analysis
Geographic Information System - utilizing digital spatial data to calculate results and create mapping products.

GIS is an essential tool employed at EDAI, ltd. in most landscape and watershed projects.

Debris flow prediction offered by EDAI, ltd. is informed by in-depth utilization of mathematical, geospatial modeling calculation methods, combined with 28 years of experience observing and analyzing debris flows on site throughout the western United States, and in great varieties of environments, topography, precipitation regimes, climates, vegetation types, soils and lithologies.

Debris Flow Prediction
Debris Flow modeling is utilized to quantify the probability of debris flow occurrence and estimate potential volume of sediment and water delivery resulting in the event of a debris flow, specific to rainfall event recurrence intervals for specific geographic locations.  Geospatial debris flow modelling is utilized to generate map products showing debris flow probability, range of potential volumes of debris flows in specific locations, stream channels and watersheds, represented spatially on a map, and GIS datasets can be overlain with other datasets to determine infrastructure and other items of concern, to inform response to protect life and safety, property, and resources.

Utilization of debris flow modeling can be useful for determining level of risk of areas, structures, and infrastructure in the potential flow path of debris flows, of one of nature's most destructive phenomenon.   EDAI, ltd. offers refined quantitative prediction for utilization in determining with greater accuracy the design or mitigating treatments to protect infrastructure, structures, and life and safety.
