Hydrologic data in small watersheds, coal-mining region, west-central Indiana, October 1980 to June 1983, and instrumentation and methods of collecting the data

Hydrologic data were collected in seven watersheds ranging in area from 0.11 to 4.87 square miles. Principal uses of land include farming in two of the watersheds, farming and forestry in one, farming and unreclaimed surface coal mines in one, reclaimed surface coal mines in two, and an unreclaimed surface coal mine in one.

Methods and instrumentation used in collecting samples and measuring concentrations and properties of the following types of data are described in the text: streamflow in seven watersheds; ground-water levels in 46 wells in unconsolidated material and 12 wells in bedrock in or near the watersheds; precipitation in seven watersheds; solar radiation, relative humidity, wind speed, and temperature of air and soil at one location; and pH, specific conductance, temperature of water, and concentrations of selected chemical constituents and suspended sediment in two watersheds.
