Level 3- Highly Addressed, Level 2-Moderately Addressed, Level 1-Low Addressed.

Method is to relate the level of PO with the number of hours devoted to the COs which address the given PO.
If >40% of classroom sessions addressing a particular PO, it is considered that PO is addressed at Level 3
If 25 to 40% of classroom sessions addressing a particular PO, it is considered that PO is addressed at Level 2 If 5 to 25% of classroom sessions addressing a particular PO, it is considered that PO is addressed at Level 1 If < 5% of classroom sessions addressing a particular PO, it is considered that PO is considered not-addressed.

ೱSUGGESTED STUDENT ACTIVITIES
Identify the spoiled earthen embankment nearby and prepare a report with drawing

1. Visit to a nearby canal, take the field data and draw the c/s of canal.
2. Identify and take the details of existing tank weir/tank sluice in the vicinity of your area and draw all the views.
3. Identify and take the details of existing culvert/highway bridge/railway bridge nearby and draw all the views.
4. For the given data prepare a model of any one of the following.
Tank sluice
Tank weir
Culvert
Railway/Highway bridge

NOTE:
1. Students should select any one of the above or other topics relevant to the subject approved by the concerned faculty, individually or in a group of 3 to 5. Students should mandatorily submit a written report and make a presentation on the topic. The task should not be repeated among students. Report will be evaluated by the faculty as per rubrics. Weightage for 5 marks Internal Assessment shall be as follows:
(Unsatisfactory- 1, Developing -2, Satisfactory -3, Good- 4, Exemplary- 5)
2. Report should contain log sheet, respective drawings and photos
3. Reports should be made available to IA verification officer.
