Unit 21

Stream flow modeling

unit hydrograph terms
Important terms in unit hydrograph theory. From: Comet (2018)

This unit covers the current state-of-the art of modeling runoff so that the entire hydrometeorological cycle can be simulated in a closed manner.

Goals

The goal of this unit is to introduce different concepts of modeling runoff in hydrological, river forecasting and climate/Earth system model applications.

After successful completion of this unit students will be able to

  1. Describe channel processes and hydraulic relations
  2. Explain simple stream-flow routing, rainfall-runoff modeling in terms of runoff processes, watershed properties, the watershed as an impulse-response system and required input quantities (graduate students)

Students’ tasks

  1. Read Dingman’s Chapter 10.5 to 10.6.4 (included)
  2. Take this MeTEd module on runoff sections soil properties (all except for review questions), Modeling concepts (all except for review questions), and Basin properties (all except urbanization, review questions, and exercise on urbanization). Skip the pre-assessments and the quizzes in the module. If you don’t have already a MetEd account, the module will lead you thru the signup process prior to your being able to take the module.
  3. Take notes to prepare to fill out the questionnaire prior to the deadline
  4. Work the Unit 21 Applications that are assigned at your class level in this task sheet and submit the scanned solution prior to the deadline.
