oa Civil Engineering = Siviele Ingenieurswese - Modelling of outflow hydrographs for dams with uncontrolled spillways and gated spillways : information technology

Volume 16, Issue 2
  • ISSN : 1021-2000



The modelling of outflow hydrographs for dams with uncontrolled spillways is an iterative arithmetic process which lends itself well to spreadsheet calculation. The outflow period is broken up into discrete time increments to create a tabular format and inflows, outflows and other related data can be calculated for each time period. Modern spreadsheets (as opposed to earlier DOS versions) also have powerful charting capabilities where the copious amounts of tabulated input and output data can be conveniently summarised and presented in chart form.
