| Abstract | An algorithm is developed for the analysis of spatially distributed hydrologic data by kriging, It outlines the procedure for structure identification in the form of generalized covariances corresponding to IRF-k theory, and procedure to perform point and block kriging. For the purpose of analysis, a hypothetical precipitation field is considered with two types of areal distribution: symmetric and unsymmetric. The hypothetical storms help to compare the results with reality at any stage of analysis. The kriging techniques are applied to evaluate optimal interpolations at ungauged sites, optimal estimation of areal averages and optimal network design. The results are compared with the traditional approaches in practice. The investigation depicts the superiority of kriging techniques over the other methods. This is due to the availability of a measurement of accuracy associated with the kriged estimates, which is the "kriging estimation variance." Most of the methods currently used in hydro sciences for interpolation and spatial averaging fail to quantify the accuracy of estimates. As an application to the real world situation the piezometric heads measured at Phra-Pradaeng aquifer (Bangkok) in 1981, are analyzed by kriging techniques and the results are compared with model calibration analysis. The kriging estimates prove to be more accurate and realistic. |
