OPTIMAL OPERATING POLICIES FOR RAVISHANKAR SAGAR RESERVOIR ? A CASE STUDY

Creation of storages through development of Reservoirs is the major avenue for meeting the water demands. For various beneficial uses in country like India where 90-95% water is available in monsoon months only it is required to create storage facilities. The available resource is becoming scarce day by day due to enormous population growth and industrial development. Availability of limited sites for creating storages on Major Rivers and their tributaries is also a constraint in development of many reservoir projects. The optimal utilization of available resource seems to be the key for tackling the complex situation of meeting the ever increasing demand of water. Development of strategies for operating a reservoir in an optimal manner to have the judicious use of available resource is also a complex phenomenon and required the use of System Analysis Techniques. There is no general algorithm for all reservoirs, and then each reservoir is to be tackled independently for developing the optimal operating strategies. Considering the a b o v e aspects the present study is f o c u s e d on developing the strategies for optimal utilization of w a t e r i n an existing reservoir in MRP Complex in Chhattisgarh State

ESTIMATION AND VALIDATION OF RUNOFF AND SEDIMENT YIELD MODEL FOR NANI CHIKALI WATERSHED

The hydraulic studies were carried out on Nani Chikali watershed which is situated in Narmada district about 23 kilometers from Rajpipla. It is located between 22? 4? 28.47? to 22? 7? 24.47? N Latitude and 74? 33? 11? to 74? 51? 41.59? E Longitude. The weekly runoff and sediment yield models are used for estimation of runoff and sediment yield in the study. The linear model was applied to measure the runoff and sediment yield. The parameters of model were calculated by multiple regression method using SPSS statistics software. The performance of model was evaluated by performing the quantitative tests which indicates that average absolute prediction error ranged from 2.08 % to 4.16 % and 2.16 % to 3.96 % for runoff and sediment yield models respectively. The coefficient of efficiency ranged from 81.88 % to 87.25 % and 81.68 % to 90.80 % for runoff and sediment yield models respectively. The overall results clearly indicate that the runoff and sediment yield models used for Nani Chikali watershed can be use for predicting runoff and sediment yield for similar watershed

IRRIGATION SCHEDULING STRATEGIES FOR COTTON CROP IN SEMI - ARID CLIMATE USING WEAP MODEL

There is constant competing demand for water amongst agricultural, industrial and domestic users as it is fixed and limited resource. With limited availability of irrigation water in arid and semi arid regions it has become necessary to optimize water use efficiency and maximize crop yields under deficit irrigation conditions. Water shortage during the growth period has an impact on ultimate yields. There is need to adopt such irrigation scheduling techniques by which it is possible to have more effective and optimal use of limited supplies of water. Regulated deficit irrigation provides a means of reducing water consumption while minimizing adverse effects on yield. Cotton crop has been taken for case study to simulate the response to deficit irrigation during flowering stage and boll formation stage. A case study was taken to investigate water stress induced during flowering stage and boll formation phase by withholding irrigation by 10days. The simulations for case study indicate that regulated deficit irrigation is resulting in marginal reduction in yield while there is significant increase in irrigation water use efficiency (IWUE) in comparison to conventional practices. Saving of water can be achieved by determining irrigation requirements in real time by using WEAP model incorporating MABIA method.

ISSUES IN INTEGRATED WATER RESOURCE MANAGEMENT IN INDIA

Need for Integrated Water Resource Management (IWRM) has been emphasized at various national and international forums. However, its implementation in developing countries and particularly in India is found to be faced with many challenges. This paper makes a critical review of IWRM concept and highlights the challenges keeping in view the Indian water laws and water conflict resolution process. There have been several initiatives in basin approach but for adhoc purposes and not for IWRM. Model river basin organization as proposed by National Commission for Integrated Water Resource Development Plan (NCIWRDP) is examined. Conclusions are drawn and recommendations are made based on the current status of water resource management. It is hoped that this paper will lead to better awareness of growing water challenges to water resource management in India.

GROUNDWATER QUALITY STUDY IN FARRUKHNAGAR BLOCK, GURGAON DISTRICT, HARYANA USING GIS

Groundwater is a major source for fulfilling the requirement in different sectors like drinking water, irrigation and industrial uses. The good quality and quantity of groundwater plays vital role in the development of an area. Geographic Information System (GIS) is of tremendous utility in understanding, representing and interpreting the data in spatial and non-spatial forms. In the present study, Arc GIS 9.3 software has been used to assess the groundwater quality of Farrukhnagar Block of Gurgaon District, Haryana. Seven groundwater samples have been collected from different locations during field visit. Ten water quality parameters- pH, total dissolved solids (TDS), total alkalinity (Ak), total hardness (TH), iron (Fe), chloride (Cl), nitrate (NO3), fluoride (F), ammonia (NH3) and free residual chlorine (RC) have been analyzed using field water testing kit prepared by TDWD, Chennai for Post-Monsoon-2013 and Pre-Monsoon-2014 seasons. In GIS environment, Inverse Distance Weighted (IDW) technique has been used for interpolation of each parameter. Categorization of parameters has been done as per BIS IS10500:2012 drinking water standards. All the ten parameter layers have been integrated to prepare integrated groundwater quality maps for post-monsoon and pre-monsoon seasons seperately. The overall groundwater quality falls in three categoriesdesirable, permissible and non-potable in the block in both seasons. The findings of the study can be used for planning, development and management of drinking water in the block

MEASUREMENT OF DISSOLVED OXYGEN AND BIOCHEMICAL OXYGEN DEMAND FOR THE HINDON RIVER, INDIA

The river Hindon (a tributary of the Yamuna river) is mainly polluted due to untreated and/or partially treated sewage discharge from municipal and/or industrial sources located within its catchment. The discharge of high biochemical oxygen demand (BOD) sewage is harmful for survival of aquatic life in a water body. Dissolved oxygen (DO) is one of the most important water quality parameters used for assessing the quality of the water for survival of the aquatic life. The high BOD load becomes responsible for lowering the DO levels in a water body. When DO drops below 4 or 5 mg/L, the forms of life that can survive begins to reduce. In this study, prediction of dissolved oxygen was carried out using Ponce Calculator and BOD using simple first order BOD reaction equation. The study is useful for assessing self purification capacity and to sustain aquatic life in the River Hindon.
