Course Outcome

Description

CO1 Students will be able to know the hydrologic cycle, which describes the continuous movement of water on,above and below the surface of the Earth.

CO2 Awareness will be developed of various types of precipitation and analysis of precipitation

CO3 student will be able to know that precipitation either directly generates surface runoff or is abstracted, which includes infiltration into groundwater or interflow, evaptranspiration through plants, interception by vegetation, or depression storage

CO4 Students will be able to stream flow, or channel runoff, is the flow of water in streams, rivers, and other channels, and is a major element of the water cycle. It is one component of the runoff of water from the land to water bodies, the other component being surface runoff

CO5 Its help to have a descriptive statistical method that shows the number of occurrences of each rainfall by the respondents. When using frequency analysis, we can also calculate the mean, median and mode to help us analyze the results and draw conclusions.

CO6 Regression analysis involves identifying the relationship between a dependent variable and one or more independent variables. A model of the relationship is hypothesized, and estimates of the parameter values are used to develop an estimated regression equation

CO7 Students will be able to describe how groundwater is affected by porosity and permeability of geologic materials with respect to different types of aquifers. Compare and contrast potential well use

CO8 Use of flood routing in hydrologic studies is in computing natural flood hydrographs for long-term gagging stations on streams where major storage reservoirs are present
