Historic Drainage Path
Rivers and creeks are dynamic systems, forever changing. A simple change in the watershed can alter their paths and flow regimes. Here I used the Relative Elevation Method, also known as, Height Above the Nearest Drainage method to highlight historic paths of the Perche creek in Columbia, Missouri. This work is done in the python environment using LiDAR data from MSDIS.
Depressional Wetland
Depressional wetland hydrodynamics play a crucial role in supporting the survival and flourishing of various species within wetland habitats. Modern day LiDAR data can be used to understand these dynamics to proper scale. Open-access python packages are used to perform this analysis.
Levee Detection
Levees are important in protecting our floodplains and controlling the hydrology of our river systems. The location of many of the nations levees are not documented. Here I have developed a deep learning based algorithm that detect, traces and maps levee features. The red line is the levee pilot which traces levees in the floodplain.
Wetland Recharging Groundwater
Wetlands are natural treatment systems. Here is a finite element model of McBain conservation area wetland which receives wastewater from the the City of Columbia. Before groundwater arrives in the McBain aquifers in north, its contaminant concentration decreases drastically.
Wetland Hydrology and Vegetation
It is very important to have a way to know the dynamics of wetland hydrology. I have been chasing methods to do this for years. Synthetic Aperture Radar seems to be very promising in this area, but radar can be interrupted by the branches and tree trunks we see in this marsh. What do you recommend to solve this problem?
Tracing Soil Moisture from Space
Radar wavelength of 3cm to 30 cm are very sensitive to soil moisture content. In our quest for soil water we used Sentinel 1 satellite data to trace the soil water in Shaw Nature Conservation Area. The process is done in Python environment and data is downloaded and processed using Alaska Satellite Facility.
Radar Driven Wetland Water Surface
Capella high resolution radar product can be used to map and monitor water dynamics in wetland environment. Here we used Cappella public ally available data to discriminate surface water pixels using python.
