THE FIELD OBSERVATION OF SOME DREDGING PARAMETERS
One of the most important questions in dredging practice is the prediction of the pipe friction head losses and the head-discharge curve of the dredge pump with the change of concentration or grain size of solids. Many equations for these parameters are known, unfortunately with many contradictions, because most of the equations are based on small pipe (or pump) experiments. Due to difficulties with 'scale-up effects' full scale experience are required. Results of some investigations of this kind are compared with the results of theoretical calculation. Moreover, advantages and disadvantages of field observations and laboratory experiments are compared.
