The Belmont Hydrology and Fine Sediment Lab: Resources


Department of Watershed Sciences

Our lab has developed several tools for automated mapping of floodplain and terrace features:

TerEx Tool:

TerEx Screen Shot

TerEx Tool: for automated mapping of terrace and floodplain surfaces from lidar using local relief and a few other user-specified criteria. This tool can be run as an ArcGIS plugin or in a Python environment. For more information, see:

Barr-NCED Floodplain Mapper:

Flood Plains

Barr-NCED Floodplain Mapper: for automated mapping of floodplain inundation on lidar from user inputs of water surface elevation at multiple cross sections. This tool is a plugin for ArcGIS. For more information, see:

Our lab developed the HydroME toolbox, which contains several tools useful for calibrating watershed hydrologic models:

HydroME Toolbox:

TerEx Screen Shot

The HydroME Toolbox contains several tools to aid with the calibration of a hydrologic model in the time and frequency domains. HydroME generates box plots to illustrate the full distribution of common model performance metrics, such as NSE or R2, Euclidian distance and empirical Quantile-Quantile (Q-Q) plots, and flow duration curves, as well as magnitude squared Fourier coherence and wavelet coherence plots to localize frequency mismatches in time. The accompanying MS Excel files contain example data in the format needed for the toolbox to generate the plots. Update with your data to generate the plots.

FDC Toolbox :

Flood Plains

The FDC toolbox is a subset of the HydroME Toolbox for generating Flow Duration Curve plots that can be used to compare measured and simulated flows. Use the accompanying MS Excel file as example data.

My lab is located in the Biology-Natural Resources building and is equipped to do the following:

The photo below shows our meeting and computing lab, adjacent to our wet lab.

The photo below shows our Acoustic Dopplar Current Profiler (ADCP) rigged to the front of a cataraft in the Yampa River. Attached to the ADCP is a Leica rtkGPS. With these two devices we can measure river discharge, the velocity profile with depth in a river, and map the bathymetry of a lake or river. Recently, we have mapped over 150 km of the mainstem Minnesota River.



Bathymetric maps developed in 2015 for select reaches of the Minnesota River:
bathymetry near Mankato MN              bathymetry near St. Peter MN         bathymetry near Skakopee MN    

 

Figures below show grain size distributions for three samples, the first collected from a floodplain, the second collected as suspended sediment in a river, and the third sample was sieved for very fine sand.
