Management Of The Hydrologic System In Areas Subject To Coal Mining Activities, Rollin H. Hotchkiss, Eugene K. Israelsen, J. Paul Riley
Reports
Publicity given to the detrimental effects of mining activities on the environment has tended to overshadow somewhat the hydrologic opportunities and benfits that could be associated with these activities. For example, many areas disturbed by surface mining have proved to be excellent recharge areas for groundwater aquifers. The degree to which mine sites can be exploited to improve management of the hydrologic system depends on both the local geology and the mining techniques used. The report examines the effects of present mining activities on the associated hydrology system, and identifies specific mining procedures and management techniques which not only minimize …

Instrumentation And Development Of Techniques To Measure And Evaluate Meteorological Parameters Important To Hydrology, Duane G. Chadwick
Reports
Hydro-meteorological instrumentation concepts are discussed. The necessity for an economic and reliable telemetering system is recognized and ways are shown how to achieve this objective. Particular discussion is given on total-precipitation and water-content-of-snow sensing. A method is also presented showing how to make isohyetal plots of telemetered precipitation information on an x-y plotter by use of a resistance paper method in conjunction with an analog computer.
