those concerning research and development that may produce more long-term and general benefits to the evaluation of the hydrologic functions of surface-mined areas in the future. GROUND WATER RECHARGE CAPACITY INTERPRETED CONCLUSION: "Ground water recharge capacity"~has no clear -95

However, spatial and temporal variabilities would require intensive instrumentation at high costs, and these variabilities and the uncertainty in measurement techniques would generally preclude accurate extrapolation to mine-scale areas. Nonpoint methods for estimating ground water recharge, made by hydrograph separation, tracer techniques, and regional water budgets, are also

RECOMMENDATION: No single technique or set of techniques for assessing recharge at required as rat provision of SMCRA. v surface coal mines should be Dart of the "recharge-cacacitY" CONCLUSION: Although accurate determination of differences between pre- and post-mining recharge rates is not practical, the committee concluded that enforcement of existing OSM regulations concerning mine reclamation will, in the vast majority of situations, result in post-mining recharge rates that equal or exceed pre-mining rates.

5221. CONCLUSION: The impacts of mining on the hydrology of a region with many mining operations may be substantial but are currently not well known, because cumulative hydrologic impact studies currently are difficult to conduct in a meaningful manner due to the lack of a central digitized data base.

(A written review of the reclamation project could take place at the time of bond release.) All the above data should be incorporated into the above mentioned Geographic Information System data base for use in subsequent cumulative hydrologic impact studies.

-100CONCLUSION: Soil compaction can be a major factor affecting the restoration of the recharge process in a reclaimed landscape. RECOMMENDATION: Innovative methods should be developed for overcoming compaction problems in reclaimed spoil materials and minesoils, particularly in surface-mined areas with identified compaction problems.
