The is a very technical post. This is a primer to discuss how LiDAR data is collected, filtered and manipulated to create digital elevation models (DEM) and how those DEMs might be used to identify fluvial geomorphic signatures that indicate where a flood hazard might exist. LiDAR data is commonly used in geomorphic analysis, hydraulicContinue reading “A primer on Fluvial Hazard Zone Mapping with LiDAR data”

February 18, 2023 NRCS Data collection and Snow Water Equivalent
The Snow Water Equivalent (SWE) is not as optimistic as some would hope. Below is a screen shot taken from the NRCS interactive website. The color-coded points are the locations the SWE is measured. The percent value is compared with the peak based on the median peak which is calculated for the period of record.Continue reading “February 18, 2023 NRCS Data collection and Snow Water Equivalent”
