Indiana-Kentucky Climate Response Network

Do you recall the drought of 2012? Precipitation deficits during July 2012 were widespread. Morse Reservoir was a prominent sight that was highly visible in the news. Photos showed million dollar mansions with boats stranded on the lakebed. This drought took many by surprise, however, there were hydrologic signs during 2011. Events like this (and California) have brought some welcome attention...

Hurricane Sandy Impacts on Coastal Wetland Resilience in the Northeast United States

The Challenge: The high winds and storm surge associated with Hurricane Sandy impacted coastal wetlands from Virginia to Maine. Understanding the ecological and geological impacts of hurricanes on coastal wetlands and their interactive effects with local conditions is important for identifying resilience of these communities to predicted global sea-level rise. Given the projected increase in...

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...

Sentinel Monitoring for New and Legacy Pesticides in the Shallow Groundwater of Long Island

Problem The shallow groundwater of Nassau and Suffolk Counties is prone to contamination from current land-use, including agricultural, residential, and recreational. The aquifer system of Long Island is highly susceptible to human-derived contamination, in particular, because the soils and underlying sediments are generally composed of sandy, permeable materials that allow contaminants to...

Delineation of the Hydrogeologic Framework and Saltwater-Freshwater Interface and Determination of Water-Supply Sustainability of Long Island, New York

Problem Long Island’s sole-source aquifer system, which includes the Lloyd, Magothy, Jameco, and upper glacial aquifers, supplies groundwater to over 2.8 million people. As a coastal aquifer system, it is susceptible to saltwater intrusion. Past pumpage and sewering (fig. 1) resulted in increased salinity in most aquifers in all counties (Buxton and Shernoff, 1999; Misut and others, 2004;...

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....

Latitudinal limits to the predicted increase of the peatland carbon sink with warming

The carbon sink potential of peatlands depends on the balance of carbon uptake by plants and microbial decomposition. The rates of both these processes will increase with warming but it remains unclear which will dominate the global peatland response. Here we examine the global relationship between peatland carbon accumulation rates during the...
