TRANSCRIPT
Conclusion
It is clear that the material considered in this monograph does not exhaust the widediversity of hydrogeological problems whose solution requires the use of the appa-ratus of groundwater migration theory. The priority in the choice of the problemswas primarily determined by the experience of the author in processing the actual(both field and laboratory) materials collected during studies at real hydrogeolog-ical sites. The author believes that this experience has clearly demonstrated that,methodologically, the integrated approach to studying phenomena of mass transferaccompanied by chemical reactions in the subsurface basing on the combination ofanalytical, numerical, and numerical–analytical methods of studies is most produc-tive in both the solution of applied hydrogeological problems and conceptual modelconstruction aimed at the development of basic knowledge about solute migrationin the subsurface hydrosphere.
The author also hopes that this book will help the reader to see that to find effec-tive solutions of some hydrogeological problems does not always require one to useextremely complex calculation algorithms involving the entire spectrum of possiblemigration mechanisms and hydrochemical interactions. Although the state-of-the-art in numerical modeling methods in hydrogeology allows the researcher to copewith problems of practically any complexity, the obtained results are commonlynot convincing because it is difficult to properly evaluate all parameters of suchnumerical models. Therefore, the use of reasonably simplified analytical models,which were the main focus of this study, and, sometimes, expert estimates mayyield more tangible and practically significant results. The solution of practical(engineering) problems is impossible without the involvement of diverse geologicaland experimental material and requires the results to be checked against alternativemodels. The hope to awake hydrogeologists’ interest in the search for new, alterna-tive solutions of the problems considered in this book was among the incentives forthe author to write it.
Unfortunately, the prescribed, and thus limited, volume of this monograph failedto allow the author to consider some processes accompanying the multiphase flowof immiscible fluids denoted by the well-known abbreviation NAPLs and knownmost often to be hazardous groundwater pollutants often not less toxic than ra-dionuclides. This range of multiphase flow problems also includes the descriptionof motion in geological beds of liquefied greenhouse gases – a problem currently
