Factors that impact a flow hydrograph
WebThe climatic factors that influence the hydrograph shape and the volume of runoff are: 1) rainfall intensity 2) rainfall duration; 3) distribution of rainfall on the basin; 4) direction of storm movement; 5) type of storm. Rainfall … WebHot, dry conditions and cold, freezing conditions result in hard ground, reducing infiltration and increasing surface runoff, this leads to a reduced lag time and peak discharge. High temperatures can also increase …

Webaffect flood flow. Rainfall-runoff models are, essentially, composed of the following parts: • Rainfall • Rainfall losses • Sub-basin response • Routing • Input hydrograph • Channel and reservoir storage The parameters selected to represent the watershed characteristics are generally adjusted through a calibration process. Web3) Use the resulting value as a user defined target flow in the subarea, instead of the predeveloped. By doing this, a Modified Rational hydrograph can be generated, since the post developed peak will be greater than the predeveloped peak. What if I need to apply a different adjustment factor to the rational C for each return event?
