In support of a preliminary analysis performed by New York State Department of Environmental Conservation (NYSDEC) that found elevated nutrient levels along selected reaches of the Mohawk River, one-dimensional, unsteady, hydraulic and water-quality models using HEC-RAS and HEC-RAS Nutrient Simulation Module I (version 5.0.3) were developed by the U.S. Geological Survey (USGS) for the 127-mile reach of the Mohawk River between Rome and Cohoes, New York. The models were designed to accurately simulate within-channel flow conditions for this highly regulated, control structure dense river reach. The models were calibrated for the study period of May through September 2016 using best available streamflow, temperature,...

This dataset provides model specifications used to estimate metabolism. The format is a table with 1 row per model (1 tab-delimited file, compressed into zip file). The specific format of this configuration file is arbitrary and specific to this analysis, and the format need not be replicated to use streamMetabolizer; however, this tabular format is useful because it allows for the reading by both humans and computers of (1) the combinations of sites and temporal resolutions for which models were run, (2) the timeseries data that were selected and combined to prepare the input to each model, and (3) the model specifications and parameters that were used in each model application. This dataset is part of a larger...
The dataset contains daily values of hydrologic and physical parameters. These daily values were calculated from continuous (15-minute) data collected from continuous water quality monitors (CWQMs) installed at five gaged sites within the Little Blue River watershed in Independence, Missouri. The data were used as input to regression models to predict Escherichia coli (E. coli) loads. Any data estimation was performed according to procedures described in the WEFTEC 2017 conference proceedings paper "Evaluation of Modeled Bacteria Loads Along an Impaired Stream Reach Receiving Discharge from a Municipal Separate Storm Sewer System in Independence, Mo." Periods of missing daily values were due to equipment malfunction,...

Ecosystem metabolism is a measure of energy flow in terrestrial and aquatic environments that quantifies a balance between the rate of biomass production by photosynthesizing plants and the rate of biomass oxidation by respiring plants and animals to maintain and build living biomass. It is therefore a fundamental measure of ecosystem function that quantifies the balance between the rate of production, maintenance, and decay of organic matter. It also provides an understanding of energy flow to higher trophic levels that supports food webs with secondary and tertiary productivity. Furthermore, metabolism helps explain when aquatic ecosystems undergo out-of-balance behaviors such as hypoxia. Recent advances in sensor...

Problem Dissolved oxygen (DO) is an important indicator of water quality that until recently has been cost-prohibitive to monitor extensively in both space and time. Continuous water-quality data, particularly in coastal environments with bidirectional tidal flow, is necessary for resource managers to understand the dynamic changes in water quality that occur tidally, daily, seasonally, and during aperiodic events. In the estuaries surrounding Long Island, such events may include wastewater treatment plant failures, harmful algal blooms, and extreme weather. The U.S. Geological Survey (USGS) has extensive experience with continuous water-quality monitoring at fixed locations along the coast that provides valuable...
