DETAILS OF RESEARCH/CONSULTANCY RESEARCH-1 a)     Surface water quality and its environmental relevance form an important issue of study. This was done by carrying out water quality parameters modeling using remote sensing data by establishing area specific correlation between various surface water quality parameters such as Total Suspended solids, turbidity and other parameters with spectral reflectance. b)    The coordinates of spectral signatures at sampled locations was obtained using differential GPS and temporal/spectral correlation was established. The regression equation relating water quality with spectral radiance was also established in the study.

RESEARCH-2 Remote sensing data acquired on a particular crop phenological period for both Rabi and Kharif seasons was used to determine area of different crops in the watershed on the date in which the satellite data is acquired. The remote sensing based different crop spectral indices such as Normalized Difference Vegetation Index (NDVI), Ratio Vegetation Index (RVI), Perpendicular Vegetation Index (PVI) and Soil adjusted vegetation index (SAVI)   was considered as parameter for crop evaluation in the irrigated command since these spectral indices values are expected to be different for different crops. The spectral crop indices was  computed for crops through sampling process for which well distributed samples consisting of transect of pixels covering the crop type is collected to compute the spectral crop indices after converting the pixel values into spectral radiance in visible red and near infrared region. The sampling was resorted for each crop type after its identification on the ground as well as on the satellite data The crop indices was utilized to identify the possibility of crop identification and to model for evapo-transpiration at different crop phenological periods.

 RESEARCH-3 The assessment of climate change was carried out by analyzing rainfall variability, temporal climatic changes, spatial interpolation of climatic factors and climatic risking. The climatic changes have consequences on precipitation pattern changes, temperature variation, crop growing season alteration, increase of sea ice and grounded ice sheets. This has implications on ecosystem, human health, settlement and agriculture. Some of the repercussions attributed to temperature and precipitation increase was proposed along with its repercussions on extreme Precipitation events like floods and droughts, agricultural yield and negative impact on subsistence agriculture. Hyper spectral remote sensing data and NOAA data was utilized since it can help in identification of ocean related parameters.

RESEARCH-4 The snow melt runoff due to melting of glaciers and consequent reduction in its area is considered as a negative impact of climatic change. The snow covered area once mapped can be integrated with altitude and other meteorological data into various models for quantifying the snow melt runoff arriving into the river or oceans. In this context a model was established linking all the interrelated parameters. RESEARCH-5             The irrigated command area requires specification of frequency of irrigation based upon the evapo-transpiration, field capacity of soil, depth of root zone and soil density. In this context estimation of the amount of irrigation water was done along with frequency of irrigation for proper scheduling. The remote sensing multi-temporal data for the purpose was used to enable computation of number of days for each irrigation water application to the respective crop groups in different watersheds by knowing the base period of different crops. In this context it is possible to obtain number of times irrigation water is to be applied along with quantity of irrigation water needed for each application.

RESEARCH-6 The runoff estimation utilizing the soil conservation services (SCS) model using LISS-III remote sensing data was used to applied groups of automatically delineated micro-watersheds each group containing about two to six micro-watersheds. The various vector layers like the slope/aspect, land-use/land-cover, runoff potential, soil erosion potential and the associated attribute information governing the criteria for different conservation structures was evolved and integrated in the spatial analysis module in GIS environment to evolve derived layers indicating the locations of conservation sites meeting the requisite criteria.

RESEARCH-7 Analytical Hierarchy Process models were used to obtain the reliability estimates for the chosen hydrological conservation sites. In this context multi-criteria weighted analysis was applied the chosen hydrological planning area utilizing different parameters to ascertain its reliability.
