    Drought assessment and characterization in Shipra river Basin of Madhya Pradesh
    (JNKVV, 2015) Baghel, Nidhi; Mishra, K.L.
    ABSTRACT Drought is defined as a water shortage caused by the imbalance between water supply and demand. The occurrence of drought leads to reduction in stream-flow, and consequent reduction in reservoir and tank levels and depletion of soil moisture and groundwater. Thus there is a need to develop suitable criteria for planning of water resource management in drought prone region. The present study is aimed to study hydrological and meterological aspects of drought in Shipra River basin as the recurrence of drought in these parts of the country in recent years have caused unprecedented economic losses and great suffering to the affected areas. The study is based on the analysis of rainfall and low flow using departure analysis, probability of exceedence and flow duration curve. The attempt has been made to quantify droughts using Standardized Precipitation Index (SPI) for various time scales. The mean annual rainfall of Shipra basin is estimated as 931 mm. The analysis indicated that the year 1972, 2000 and 2001 were most severely affected drought years in the basin as most of the area of the basin was under drought and the runoff deficit years were 2001 and 2005 at Ujjain. Shipra basin experiences drought year after every 3-4 years and almost all the basin can be categorized as drought prone area. The hydrological drought may have significant impact on water availability as Shipra river experiences on an average 1 low flow situation every year ranging from 11 to 162 days. Drought severity in the basin has been quantified using Standardized Precipitation Index (SPI), which indicate drought severity in multi time scales and classified the severity in to different events according to their magnitude. In Badnagar, Mahidpur and Dewas moderate dry to extreme dry events were commonly found so these stations require immediate attention for water resource planning and management. From other drought indices Standardized Precipitation Index is proved to be much easy and less complex index as it required only precipitation data.
