WST 615 WATER MANAGEMENT TECHNOLOGIES IN RAINFED AGRICULTURE                                                                 (2L+1P)  III

Objective
To expose the student with the various problems of water management and their solution for increasing agriculture production in rainfed areas, agriculture production as climatic change and the characterization and rain\fed areas, development and use of techniques and mathematical models.

Theory

UNIT I
Prospects of rainfed agriculture, climate change and its impact, characterization and delineation of rainfed areas, moisture stress and low productivity, concepts of blue, green, gray, black, fossil water, rainfall analysis, dry and wet spells, drought, Huff curves.

UNIT II
Techniques and mathematical models for quantification of runoff, use of GIS, RS, DSS, GPS tools and hydrological models in assessment of surface & ground water resources, uncertainty analysis, up scaling/down-scaling approaches, modified Mitscherlich equation, modern tools and crop models in water management.

UNIT III
Resource conservation techniques, improving water use efficiency, conservation tillage, water harvesting, irrigation techniques, mulches and evaporation suppressants, integrated nutrient management.

UNIT IV
Watershed development and integrated watershed management, case studies, crop diversification, farming system approach, alternate land use systems.

UNIT V
Extension strategy, RRA, PRA and PAR, economic issues, institutions and water users associations, PIM and rotational water supply schemes, research and developmental needs, policy issues, National Rainfed Area Authority.

Practicals
Characterization and delineation of rainfed areas, rainfall analysis, dry and wet spells, drought, Huff curves, techniques and mathematical models for quantification of runoff, use of GIS, RS, DSS, GPS tools and hydrological models in assessment of surface & ground water resources, uncertainty analysis.
