Fractional Operators with Constant and Variable Order with Application to Geo-Hydrology

Fractional Operators with Constant and Variable Order with Application to Geo-Hydrology provides a physical review of fractional operators, fractional variable order operators, and uncertain derivative to groundwater flow and environmental remediation. It presents a formal set of mathematical equations for the description of groundwater flow and pollution problems using the concept of non-integer order derivative. Both advantages and disadvantages of models with fractional operators are discussed. Based on the author's analyses, the book proposes new techniques for groundwater remediation including guidelines on how chemical companies can be positioned in any city to avoid groundwater pollution. Trans-boundaries aquifers problem between two or more nations sharing borders are also discussed. Proposes new aquifer derivatives for leaky, confined and unconfined formations, useful aids for those applied scientists and engineers seeking to solve complex problems that cannot be handled using constant fractional order derivativesProvides a real physical interpretation of operators relevant to groundwater flow problemsModels both fractional and variable order derivative, presented together with uncertainties analysis INDICE: 1.
