Drought can not be defined as Flood. No single definition is available for drought. The beginning and end of drought are difficult to identify.  Drought can be, however, identified through various indicators such as rainfall, snowpack, streamflow, and more, and these indicators can be used to monitor drought. Different scientists and researchers have developed various indices to help determine the onset, severity, and end of droughts. Drought indices are multiparameter and based on long or short duration observation of data for such parameters which help them create a comprehensible big picture. A drought index value is typically a single number that is calculated based on the data of input parameters generally rainfall, snowpack, evapotranspiration, etc., and is interpreted on a scale of abnormally wet, average, and abnormally dry.( Reference ) The video below elaborates the concept : Although drought is very difficult to determine the significance of drought in agriculture, water...

The summer season can be utilized by the pursue of research on the following few ideas. The ideas are developed based on the type of audience that means whether  B.Tech. or M.Tech, Students or Teachers, etc. students will enjoy doing these topics to complete their PG or UG requirement. Title: Short Term Rainfall forecasting by ANN-MCDM Approach Pre-requisite : Various data of climatic parameters, land use pattern of the region, cloud type and density for 1 to 5 days before the day of forecast. Justification of the Study : Rainfall can impact the output of many industrial and agricultural processes. Even the energy output from the power sector is affected by the climatic parameter. Short term rainfall forecasting is an important concept as it can help the planners of this industry to adjust their input so that the required output will remain unaffected. Brief Methodology : A widescale expert and local survey followed by a literature review have to be conducted to identify the p...

Watershed retain water from rainfall within its soil pores and depressions available in the basin. If this capacity of retention get receeded there will be stress on the supply of both water and food to dependent consumers. Check, whether the watershed on which you are staying maintains a healthy retention capacity ? A new tool will help you to ascertain the same and make you prepared for the uncertainties that may come if the retention capacity of your watershed has changed negatively.
