Data

This data release contains a database reviewing the state of the science for physically based distributed hydrologic model applications for post-fire hydrologic response. The database covers the globe and spans from the years 1998 through the calendar year 2021. The database is part of a larger state of the science review of post-fire hydrologic modeling that examines the scales and...

This archive contains results of flow and sediment transport simulations of a reach of the Middle Channel of the St. Clair River delta, Michigan using the iRIC modeling system and the Flow and Sediment Transport with Morphologic Evolution of Channels (FASTMECH) solver. Two hydraulic model simulations were used to determine lateral eddy viscosity and roughness settings. A third simulation...

This version of ModelMuse fixes a serious bug in ModelMuse version 5.1.

The U.S Geological Survey conducted hydrographic surveys from September 13-16, 2021 and May 2-5, 2022 to monitor fish spawning substrate placements (reefs) in the Detroit and St. Clair Rivers, Michigan. This work was conducted as part of a reimbursable agreement with the Environmental Protection Agency to provide technical assistance in areas of concern. A multibeam echosounder was used...

The U.S. Geological Survey used a ponar sampler to collect bed material from the Middle Channel of the St. Clair River Delta on November 10, 2021. Three sediment samples were collected upstream of the artificial spawning reefs constructed in the Middle Channel and two on the reefs themselves.The bed sediment samples were dried and sieved at 1/2 phi increments to determine their grain...

ModelMuse version 5.1 updates version 5.0 by adding support for the groundwater transport process and time series files in MODFLOW 6.

The release of metals (or metalloids) to surface water can involve both natural and anthropogenic sources. Elevated metals concentrations can pose a risk to human health, wildlife, and ecosystem health, with the modes of toxicity and extent of risk varying as a function of the specific metal, its chemical form and the matrix with which it is associated (for example, dissolved versus...

A three-dimensional finite-difference model, MODFLOW-2005 (version 1.12.00), was developed to better understand how Seepage Meter efficiency changes when installed in sediments with wide range of conductivities. The hypothesis is that coarser sediments will allow a greater portion of upward-flow to flow around the meter instead of through it. The hypothetical model simulates upward flow...

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...

Data were collected between 2010 and 2022 in a research area of the Everglades known as the Decompartmentalization Physical Model (DPM), a wetland area in the central Everglades that includes canals and levees bordering Water Conservation Area 3A (WCA-3A) to the northwest and Water Conservation Area 3B (WCA-3B) to the southeast. During the twelve-year study period more than ten major...

Data were collected between 2013 and 2022 in a research area of the Everglades known as the Decompartmentalization Physical Model (DPM), a wetland area in the central Everglades that includes canals and levees bordering Water Conservation Area 3A (WCA-3A) to the northwest and Water Conservation Area 3B (WCA-3B) to the southeast. During the study more than ten major controlled flow...
