Issued by the National Hydrology Research Institute, Inland Waters Directorate. Library copy: Imperfect: preliminary pages repeated and chapt. 4 pages inverted. Includes bibliographical references. "Seasonal flooding of karst depressions may cause problems for future engineering developments in the region; the tendency of the karst to collapse presents a special geotechnical hazard in addition to the problems related to the widespread occurrence of ice-rich permafrost. The karst-water system is extremely vulnerable to contamination from the surface because of the close spacing of high-rate recharge points and the unfiltered nature of the recharge"--Abstract.
