The response matrix approach is becoming more and more widely appli-ed in the groundwater optimal management. It overcomes the defects of mbedded approach, for instance, large calculation job, great demand for sto-rage and low numerical stability, etc. It can solve the actual large scale complex problem. According to the characteristics of the coefficient matrix resulting from the response matrix approach, this paper probes into the stor-age structure of the coefficient matrix, with one-dimensional condensed table for its sparse part and two-dimensional table for its dense part. This technique avoids the waste of memory space, speeds up calculation and lightens the data preparation work. The sample calculation demonstrates that it is practical.
