Flood Inundation Mapping in Ohio, Kentucky, and Indiana

Flood inundation maps (FIMs) translate the stage of a river (shown on a hydrograph) to a map showing the extent and depth of flood waters. FIMS are created by combining datasets calculated by hydraulic models with ArcGIS, a geographic information system. FIMs can be used in conjunction with USGS real-time data and National Weather Service Flood Forecasts to plan and prepare for flood events....

Kankakee River at Davis, IN Mega Gage: Monitoring Groundwater/Surface-Water Interactions

What is the groundwater contribution to nitrates in surface water? 

That's the question we are trying to answer by looking at surface-water and groundwater interaction and the role each play in the movement of nitrates. We have added additional monitoring equipment to the USGS super gage...

National Atmospheric Deposition Program National Trends Network

The National Atmospheric Deposition Program (NADP) is a 40-year old organization of federal, state, local, academic, tribal, and private entities who support operation of 5 national monitoring networks. Kentucky and Indiana operate 3 National Trends Network (NTN) sites as part of the National Atmospheric Deposition Program (NADP).  Monitoring for NTN is consistent, standardized, high quality,...

Litterfall Mercury Monitoring Network

Litterfall is leaves, needles, flowers, fruit, and debris found on the forest floor.  Litterfall sampling can be an effective tool for monitoring elements like Mercury. Mercury in litterfall is primarily from the atmosphere and contributes to the higher amounts of mercury dry deposition that accumulates in forested areas compared to non-forested areas.

INKY scientists collect litterfall...

Indiana National Water-Quality Assessment Project

Staff have been sampling Sugar Creek at New Palestine and the White River at Hazleton heavily since the USGS National Water-Quality Assessment Program (NAWQA) pilot study in 1991. We have collected 26 years of nutrient, pesticide, major ions, and sediment data at these sites.  Our intensive data collection is critical to the science...

Computational Fluid Dynamics Analysis and Modeling

USGS scientists can perform numerical simulations with the FLOW-3D application. FLOW-3D is a computational fluid dynamics (CFD) software package with multi-physics modules. It solves the three-dimensional Navier-Stokes and continuity equations in a structured, rectangular grid. USGS scientists use CFD models to design equipment (such as the...

Cumberland Gap Study: Sediment Acquisition and Modeling of Davis Branch

Davis Branch, a stream within the boundaries of Cumberland Gap National Historical Park, is a designated Warm Water Aquatic Habitat, Primary Contact Recreation, and Outstanding State Resource Water. Historically, the stream has provided a critical habitat to the federally-threatened Blackside Dace, a small cyprinid fish endemic to the upper Cumberland River basin. In recent decades, the...
