The MIKE 11 Nedbor Afrstromnings Model is a lumped theoretical model for simulating the runoff from the precipitation. The input data utilized by the model was weighted precipitation, Potential evapotranspiration and observed runoff. The total time series of 11 years duration from 1996 to 2006 was u sed in t his study. The model calibration was done for the time frame from 1996 t o 2001 a nd va lidated for the years 2 002 t o 2 006.

Life on earth can not be p ersistent without water, whether of humans, animals, flora or fauna. Water is the natural important resource which needs preservation, control and management. Design of all water resources planning and management project require long term runoff http://iaeme.com/Home/journal/IJCIET 364 [email protected] Simulation of Rainfall Runoff of Shipra River Basin data which is generally not available at the project sites. Hence runoff has to be predicted with the help of rainfall data. Rainfall data, watershed area, and other parameters like soil type, land use pattern, vegetation and m oisture co ntent o f s oil are t he m ajor i nputs r equired f or an y k ind o f m odels. Presently the hydrological models are very important tool to calculate the runoff, sediment yield and soil erosion (Prasad and Tiwari, 2016). A rainfall runoff model is helpful in computation of discharge from a basin. A Rainfall- Runoff m odel i s a m athematical m odel w hich d escribes t h e r elation b etween r ainfall an d r unoff o f a watershed o r catch ment area. A R ainfall-Runoff m odel p roduces t h e s urface r unoff h ydrograph when precipitation is given as an input. Horton was probably the first person who gave a model which was based on i n filtration cap acity f o r t h e g eneration o f t h e r u noff ( H orton, 1 933). T he r ai nfall-runoff m odels are classified as Conceptual, Theoretical, Deterministic, Stochastic, Black box, Continuous, Complete, Event, Routing an d S implified ( Linsley, 1 982). B ecause o f m ulti-dimensional an d n on-linear n ature, rainfall- runoff modeling is ex tremely complicated (Lipiwattanakarn et al ., 2004). Various hydrologic models are available depending upon nature, complexity and purpose of the water resource project (Shoemaker et al., 1997). T he w idely k nown r ainfall-runoff m odels i d entified are t h e r ational m ethod, S oil Conservation Services Curve Number method, and Green-Ampt method (Balvanshi and Tiwari, 2014). 2. HISTORICAL REVIEW The M IKE11 N AM i s an i n tegrated an d co nceptual m odel o f r ai nfall-runoff w hich i s ab le t o simulate surface f l ow, s ubsurface an d b ase f low, t h is m odel h as b een d eveloped b y D anish H ydraulic Institute (DHI, 1972, DHI, 1999). Many studies have been conducted using MIKE11 NAM model. The reliability of the MIKE 11 NAM model was evaluated by introducing the Root Mean Square error method (Fleming, 1975). A NAM model was developed for predicting the runoff rate in Liang River located in northern part of Malaysia. The results showed that the predicted amounts by the NAM model were in accordance with the historical data appropriately and in general the results were satisfactory (Shamsdin and Hashim, 2002). MIKE 11 N AM model w as also ap plied at Y uvacik Dam b asin, Turkey t o s i mulate t h e r u noff b y using rainfall as well as snowmelt as inputs for the model (Keskin et al., 2007). The MIKE 11 NAM model was also employed for simulation on Rahatgarh site of Bina basin, Madhya Pradesh. The model was developed, calibrated and validated using stream flow data at the Rahatgarh site. The coefficient of determinations for calibration an d v alidation w ere 0 .796 an d 0 .609 r espectively. T he m odel w as f ound efficient with Efficiency Index is 81% and found suitable for extended time period in Bina basin (Galkate et al., 2011). MIKE 11 was also employed for Ujjain Basin part of Shipra Basin, Madhya Pradesh for the availability of water in the Ujjain city mainly for the Khumb Mela using MIKE 11 software (Galkate et al., 2011). 3. STUDY AREA This paper focuses on the Shipra river basin of Madhya Pradesh which is the tributary of Chambal River. It is one of the sacred rivers in Hinduism. Shipra river basin has been extended between 760 06ˈ 20 ˈˈand 750 55ˈ 6 0ˈˈ North Latitude and 220 97ˈ 0 0ˈˈ and 230 76ˈ 20ˈˈ East Longitude and covers an area of 5679 sq. km. The river traverses total course of about 190 km through four districts namely Dewas, Indore, Ujjain, and Ratlam b efore j o ining C hambal R iver n ear K alu-Kher v illage. T he Shipra, al so k nown as the Kshipra, originates from Kakribardi hills in Vindhya Range north of Dhar and flows north across the Malwa plateau to join the Chambal River. The average annual rainfall of area is about 931.87 mm. The rainfall in the area is due to the southwest monsoon which starts from the middle of June and ends in last week of September.
