Super Gage Network

 

 What is a Super Gage?

A gage at which continuous flow and water level are determined, along with continuous traditional water-quality (water temperature, specific conductance, pH, dissolved oxygen, and/or turbidity) and either of the following criteria:

  • at least one other less-traditional continuous water-quality parameter (
  • ...

Simulation of Soil-Water Availability

How much water is stored in the soil?  Does agricultural management affect this?  Will this change if temperatures increase and plants need more water? 

In order to answer this question, we have focused on the differences in soil physical properties under four land management types (forest, pasture, traditional agriculture, and conservation agriculture) and whether these differences...

Bridge Scour Countermeasures

Flood events on rivers can cause erosion of the soil around a bridge foundation. This process is frequently referred to as bridge scour. Over time, scour can lead to bridge failure. To manage the risk from bridge scour, countermeasures are now used on bridge foundations. USGS scientists will be evaluating these bridge scour countermeasures at bridges across the country on rivers of various...

River Meander Modeling - Wabash River

Significant flood events on the Wabash River between 3 mi downstream of Mt. Carmel, IL to 10 mi downstream from New Harmony, IN caused the collapse of the railroad pier, bridge, and trusses which crossed the river. Scientists are using two models to evaluate how future flooding may impact the current I-64 bridge and the river channel. One model will focus on river meander migration. The second...

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....

A Flood Alert System for Columbus, Indiana

In June 2008, heavy rainfall occurred in the upstream reaches of Haw Creek, a small stream that flows through the center of Columbus, Ind. A sudden flash flood occurred through the middle of Columbus which took the town by surprise since the rain was upstream. Many homes and more than 70 businesses were damaged in Columbus, including $125 million in damage to the Columbus Regional Hospital and...

Nutrient Delivery to the Mississippi River from Kentucky

Scientists will be collecting field water-quality parameters and samples for laboratory analysis of nutrients, silica, and suspended sediment at the USGS Ohio River at Ironton, OH gaging station and the...

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...

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...
