Purpose of the course
· To understand the theoretical basis of surface water hydrology and solve basic hydrologic problems.
Learning Objectives:
Upon successful completion of this course, learner should be able to:
· Describe measurement of stream discharge and derive hydrographs
· Solve basic hydrologic problems, to estimate the magnitude and frequency of hydrologic events.
· Evaluate water resource management problems with awareness of the interdisciplinary nature of water resource management and decision-making in Kenya
