Leslie D Arihood
Leslie Arihood worked at the U.S. Geological Survey as a hydrologist for 38 years and as a Scientist Emeritus for 7 years at the Indianapolis office. He has completed several projects in the areas of ground water, surface water, water quality, and sediment transport analysis. He is now involved in establishing a national water well log data base and in a hydrogeologic analysis of the data base.
Biography
Specific projects include groundwater and sediment transport modeling, source water assessments, aquifer testing, estimation of low flows, and watershed water-quality and wetland characteristic assessments. He specialized in the use of GIS programming to investigate ground- and surface-water resources. After retirement in 2010, he became a Scientist Emeritus with the U.S. Geological Survey. He is currently working on the USGS national glacial aquifer study converting State well log data bases into standardized GIS data sets. He has standardized the lithologic descriptions into useable code and subsequently created several interpretive grids and maps. The grids include total sand and gravel thickness, texture based hydraulic conductivity, and bedrock surface altitude, and the maps include bedrock surface lithology.
Science and Products
Maps and grids of hydrogeologic information created from standardized water-well drillers’ records of the glaciated United States
As part of the National Water Availability and Use Program established by the U.S. Geological Survey (USGS) in 2005, this study took advantage of about 14 million records from State-managed collections of water-well drillers’ records and created a database of hydrogeologic properties for the glaciated United States. The water-well drillers’...

Estimating selected low-flow frequency statistics and harmonic-mean flows for ungaged, unregulated streams in Indiana
Information on low-flow characteristics of streams is essential for the management of water resources. This report provides equations for estimating the 1-, 7-, and 30-day mean low flows for a recurrence interval of 10 years and the harmonic-mean flow at ungaged, unregulated stream sites in Indiana. These equations were developed using the low-...

Observed and forecast flood-inundation mapping application-A pilot study of an eleven-mile reach of the White River, Indianapolis, Indiana
Near-real-time and forecast flood-inundation mapping products resulted from a pilot study for an 11-mile reach of the White River in Indianapolis. The study was done by the U.S. Geological Survey (USGS), Indiana Silver Jackets hazard mitigation taskforce members, the National Weather Service (NWS), the Polis Center, and Indiana University, in...

Hydrogeology and simulation of groundwater flow at the Green Valley reclaimed coal refuse site near Terre Haute, Indiana
The Green Valley reclaimed coal refuse site, near Terre Haute, Ind., was mined for coal from 1948 to 1963. Subsurface coal was cleaned and sorted at land surface, and waste material was deposited over the native glacial till. Approximately 2.7 million cubic yards of waste was deposited over 159 acres (92.3 hectares) in tailings ponds and gob piles...

Methods for estimating selected low-flow frequency statistics for unregulated streams in Kentucky
This report provides estimates of, and presents methods for estimating, selected low-flow frequency statistics for unregulated streams in Kentucky including the 30-day mean low flows for recurrence intervals of 2 and 5 years (30Q2 and 30Q5) and the 7-day mean low flows for recurrence intervals of 5, 10, and 20 years (7Q2, 7Q10, and 7Q20)....

Processing, Analysis, and General Evaluation of Well-Driller Logs for Estimating Hydrogeologic Parameters of the Glacial Sediments in a Ground-Water Flow Model of the Lake Michigan Basin
In 2005, the U.S. Geological Survey began a pilot study for the National Assessment of Water Availability and Use Program to assess the availability of water and water use in the Great Lakes Basin. Part of the study involves constructing a ground-water flow model for the Lake Michigan part of the Basin. Most ground-water flow occurs in the glacial...

Hydrologic Characteristics of a Managed Wetland and a Natural Riverine Wetland along the Kankakee River in Northwestern Indiana
Characteristics of ground-water/surface-water interactions were identified at a managed wetland (Hog Marsh) and a natural riverine wetland (LaSalle) located on the north and south sides, respectively, of the Kankakee River in northwestern Indiana. Hog Marsh covers about 390 hectares of the Grand Kankakee Marsh County Park. LaSalle covers about 100...

Hydrogeology, water use, and simulated ground-water flow and availability in Campton township, Kane County, Illinois
Several aquifers underlying Campton Township in Kane County, Illinois provide virtually all of the water supply to the residents of the township. These aquifers consist of layers of unconsolidated sand and gravel in the glacial drift; dolomite and shale of the Alexandrian Series and the Maquoketa Group (the Silurian-Maquoketa aquifer); dolomite of...

Methods Used to Assess the Susceptibility to Contamination of Transient, Non-Community Public Ground-Water Supplies in Indiana
The Safe Water Drinking Act of 1974 as amended in 1996 gave each State the responsibility of developing a Source-Water Assessment Plan (SWAP) that is designed to protect public-water supplies from contamination. Each SWAP must include three elements: (1) a delineation of the source-water protection area, (2) an inventory of potential sources of...

Isotope hydrology dynamics of riverine wetlands in the Kankakee Watershed, Indiana
Wetland restoration activities may disturb shallow ground-water flow dynamics. There may be unintentional sources of water flowing into a constructed wetland that could compromise the long-term viability of a wetland function. Measurement of naturally-occurring isotopes in the hydrosphere can provide an indication of provenance, flow paths or...

A Study of Natural and Restored Wetland Hydrology
The U.S. Geological Survey and the U.S. Environmental Protection Agency are jointly studying the hydrology of a long-existing natural wetland and a recently restored wetland in the Kankakee River Valley in northwestern Indiana. In characterizing the two wetlands, project investigators are testing innovative methods to identify the analytical tools...

Geohydrology and quality of ground water in unconsolidated aquifers near South Bend, Indiana
IntroductionThe water supply for the City of South Bend, Indiana, and much of surrounding St. Joseph County is provided by 36 municipal and community well fields. Some of these well fields are located near known or potential sources of ground-water contamination that could affect ground-water supplies in the near future. As population and industry...
