摘要
Abstract
Standard curve method is the most commonly used way to determine the dispersion coefficient of aquifer. But its main drawback is that curves are often relied solely on individual manipulation. In view of curve fitting method, we proposed a new metaheuristic method: bat algorithm(BA), which is based on the echolocation behavior of bats, to identify the coefficient of one-dimensional flow two-dimensional hydrodynamic model. The bat algo-rithm can reduce the main error to some extent which is caused by fitting curve subjectively. Moreover, groundwa-ter velocity can be obtained directly. The case study results indicates that the proposed bat algorithm is an efficient method to solve hydrogeological parameters by utilizing the dispersion test furthermore, BA can be widely used in the solution of hydrogeological issues.关键词
