This will also avoid loss of soil due to erosion , increase the grass coverage which will helpful for soil stabilization. Due to CCT tree development is better than any other type of trenching. � � � 338
National Seminar on Rainwater Harvesting and Water Management 11-12 Nov. 2006, Nagpur 60. Planning and Design of a Rain Water Harvesting System for a Watershed of Uttaranchal INTRODUCTION In modern concept of planning and implementation of programmes for enhancing and sustaining the land productivity and efficient rainwater utilization; watershed - a geographical unit has been accepted as the most rational unit. The word ‘watershed’, introduced in 1920, was used for the ‘water parting boundaries’. Watershed is that land area which drains or contributes runoff to a common outlet. In physical terms, a watershed refer to the area lying above a given drainage point. Watershed management involves management of land surface and vegetation so as to conserve the soil and water for immediate and long-term benefits to the farmers, community and society as a whole. It is an integration of technologies within the natural *P. K. Gupta *H.C. Sharma *Vinod Kumar ABSTRACT The Henwal watershed is located in Tehri Garhwal district of Uttaranchal, between 30° 15' to 30° 20' N latitude and 78° 25' to 78° 30' E longitude, at an altitude of about 1500 m above msl. Most of the area is under rainfed agriculture, due to lack of irrigation facilities. The daily rainfall data of 14 years, of the watershed area, were analyzed for probability distribution at different levels. The analysis of estimated daily runoff values for 14 years showed that the annual runoff, more than 500 mm, was observed in 4 years, between 400 mm and 500 mm in 5 years and less than 400 mm in 4 years. The average annual and seasonal runoffs were found to be 431.7 mm and 292.4 mm, respectively. The average seasonal runoff was found to be 70 per cent of annual runoff. The expected runoff and seasonal runoff during the first excess period was 665000 m 3 and for second excess period was 175000 m 3 . On the basis of above the rainwater-harvesting pond was designed for Henwal watershed having a catchment area of 351 ha and command area of 315 ha. The bottom width, top length and height of the designed pond were 2.5, 16.6 and 3 m, respectively. The pond would have a storage capacity of 5027.4 m 3 . The total cost (excavation cost, LDPE sheet and stone pitching) of the pond was estimated to be Rs. 146689 and the cost per m 3 of stored water comes to be Rs. 29/m 3 . boundaries of drainage area for optimum development of land, water and plant resources to meet the basic needs of people in a sustained manner. The main objective of watershed management is “Proper use of all the available resources of a watershed for optimum production with minimum hazards to natural resources”. How can we, under such constraints, manage to boost agricultural production in these areas in order to satisfy the multiplying food demand of our growing population, whereas, irrigation would certainly be the best method, it requires much water, which is scare in arid and semi-arid countries. Water harvesting may be one of the solutions to overcome the problem of scarcity of water for irrigation. Water harvesting in its broadest sense may be defined as Department of Irrigation & Drainage Engineering, College of Technology G. B.
