Determination of Alluvial Sediment?s Thickness in PolrudRiver Bed

   Abstract:
      Thornburgh's wave front method of interpreting seismic refraction sections provides a very lucid and accurate tool. But its elegant precision is of little avail in over coming essential uncertainties due to ambiguities in velocity determinations. It seems a waste of time and energy to carry out precise wave front constructions when the circumstances are uncertain. In such cases a faster approximate method would be preferable and sufficient. The exploration world with a simple and rapid approximation of wave front method, because of simplicity, plus-minus method is ideally suited for real-time processing of refraction data in the field and also its capability of producing parameters for layer and rock characterizations and providing detailed velocity information on the deepest refractor with low costs both in its execution and in the data processing.
