Computational models are important tools that aid process understanding, hypothesis testing, and data interpretation. The ability to easily couple models from various domains such as, surface-water and groundwater, to form integrated models will aid studies in water resources. This project investigates the use of the Community Surface Dynamics Modeling System (CSDMS) Modeling Framework (CMF) to couple existing USGS hydrologic models into integrated models. The CMF provides a Basic Model Interface (BMI), in a range of common computer languages, that enables model coupling. In addition, the CMF also provides a Python wrapper for any model that adopts the BMI. In this project the Precipitation-Runoff Modeling...

A topographic and bathymetric survey was collected along a reach of the Green River downstream of Dinosaur National Monument. The surveyed reach extends approximately 16 kilometers upstream and 6 kilometers downstream of the U.S. Route 40 bridge near Jensen, Utah. The topographic and bathymetric data include survey point data for 382 cross sections over 22 kilometers and are provided as a text file of easting, northing and elevation, in meters. The cross-section location data were collected using real-time kinematic Global Navigation Satellite Systems (GNSS) by USGS personnel from March 26, 2018, through March 29, 2018 using a combination of Sound Navigation and Ranging (SONAR) and wading techniques.

Hyperspectral image data and field measurements of Rhodamine WT dye concentration were obtained during a tracer study conducted at the Korea Institute of Civil Engineering and Building Technology's River Experiment Center May 17-20, 2017, to support research on dispersion in river channels. The image data included in this data release were acquired using a Nano-Hyperspec (Headwall Photonics, Inc.) mounted on an Aerotestra ATNK09, a small multirotor unmanned aircraft system (UAS). The in situ concentration data were collected using electronic fluorometers (YSI 600-OMS sonde with 6130 Rhodamine WT sensor). Image time stamps were used to link concentration time series recorded by the sondes to specific pixels. The...

This data release provides measurements of dye concentration collected to support and validate numerical simulations of dispersion on the Kootenai River, downstream of Bonners Ferry, Idaho. On August 13, 2008, at 06:00, 25.4 kilograms of rhodamine WT was diluted using raw river water in a 378.5 liter tank and released as a nearly single slug. The dye was released near River Kilometer (RKM) 239 over a period of 17 minutes. From 06:01 – 06:10 the dye was released at a fairly constant rate, and from 06:10 – 06:18 the dye was released at a slower rate associated with cleaning and rinsing the tank. Measurements of dye concentration were made using water quality sondes with 6130 rhodamine probes. Two sampling strategies...

3: Archive model results for the velocity validation: This item summarizes the workflow to compare FaSTMECH simulations of velocity to measured velocity for a reach of the Kootenai River, near Bonners Ferry, ID. This work is part of a larger model archive (see Model Archive: Simulation of Rhodamine Dye Concentration and Larval Drift, Kootenai River, Idaho) that summarizes lagrangian particle-tracking simulations of dye dispersion and larval drift in this reach of river. Hydraulic model for velocity verification. The ability FaSTMECH to simulate 2- and 3-dimensional velocity in the reach was tested against ADCP measurements collected on May 16th, 2016, near the confluence with Myrtle Creek. The model sensitivity...
