COURSE TITLE: WATER RESOURCES MANAGEMENT

(Course Code: 3340604)

Diploma Programme in which this course is offered Semester in which offered

Civil engineering 4th

Semester

1. RATIONALE:

Knowing extremity of water crisis, we must appreciate water as “Nature’s greatest gift”. Our

water requirement is rapidly increasing due to vast industrial development, population growth

and changing life style. We are mostly dependent on rains as a predominant source of water. The

other important source of water is the ground water which also depends to great extent on rainfall

in previous years. We know that ground water table is declining rapidly due to its excessive use

and misuse and also due to insufficient rainfall every year. To stress upon the concept of water

management and simultaneously to create the awareness about the proper use and conservation

of water, this course is specially designed for the students of Diploma in Civil Engineering. An

attempt has been made to develop theoretical knowledge with emphasis on certain aspects of

water resources management. The topics viz. hydrology, runoff, watershed management,

recharging etc. have been specifically dealt in the curriculum.

2. COMPETENCY:

The course content should be taught and the curriculum should be implemented with the aim to

develop different types of skills so that students are able to acquire following competency:

Design the appropriate rain water harvesting scheme and required structures for managing water resources under given conditions

3. COURSE OUTCOMES

The theory should be taught and practical should be carried out in such a manner that

students are able to acquire different learning out comes in cognitive, psychomotor and

affective domain to demonstrate following course outcomes.

Discuss basic concepts of “Water Resources Management”.

Estimate the surface runoff from given precipitation data.

Describe various types of survey investigations for reservoir planning

Design the appropriate rain water harvesting scheme and required structures for given conditions.
