Abstract: An explicit calibration algorithm is proposed which provides the direct and rapid adjustment of the pipe roughness coefficients and junction node demands that exactly meet a specified set of field observations of pressure or grade at designated test nodes throughout the distribution network under multiple demand loadings and corresponding network operating conditions. Both the individual pipe roughness coefficients and the junction demands are adjusted using a set of global parameter adjustment factors. The resulting algorithm is both fast and efficient and guaranteed to yield a mathematically consistent solution.
