RS and GIS

The prolonged drought due to climate change has significantly affected the agricultural production of rural communities in the mountainous and plain areas of Vietnam. We use the standardized precipitation index (SPI) combined with Geographical Information Systems (GIS) and Remote Sensing (RS) to simulate and forecast the impacts of drought on agricultural land use in Bac Tra My district, Quang Nam province, in the study.

In this study a standard methodology is proposed to determine groundwater potential using integration of RS & GIS technique. The composite map is generated using GIS tools. The accurate information to obtain the parameters that can be considered for identifying the groundwater potential zone such as geology, slope, drainage density, geomorphic units and lineament density are generated using the satellite data and survey of India (SOI) toposheets of scale 1:50000. It is then integrated with weighted overlay in ArcGIS.

Thematic maps present information relating to spatial variations in the distribution of specific geographical features at a regional scale or across the entire basin. The spatial distribution of thematic maps aids in decision-making of management of resources. Different thematic maps generated for the Kinnerasani basin include watershed boundary, drainage network, slope map, landuse/landcover map and soil map with the help of Survey of India topographical map and Cartosat DEM. LULC map was developed using IRS P6 LISS III satellite data.

Water is one of the most essential commodities for mankind and the largest available source of fresh water lays underground. Tremendous increase in the agricultural, industrial and domestic activities in recent years has increased the demand for good quality water to meet the growing needs. Groundwater is mostly preferred to meet this growing demand because of its lower level of contamination and wider distribution. The occurrence of groundwater is a consequence of the interaction of the climatic, geological, hydrological and physiographical factors.

A detailed land resources inventory (LRI) of Amarapura-2 micro watershed was carried out at 1:8000 scale for deriving land capability and crop suitability classes. The micro watershed is located between 770 8’ to 170 17’ North latitude and 770 101 to 170 151 East longitude of Lingasaguru taluk, Raichur district, Karnataka State, India. Twenty four soil phase units with eight soil series were identified through detailed soil resource study. Land capability subclasses in the study area were IIIes and IVes with limitations of soil erosion, texture, soil drainage, soil fertility and topography.

This study uses data from Global Positioning System and Geographic Information System to produce digital maps for soil texture using the spatial analysis technique. Soil texture is one of the most important soil properties whose variability may contribute to the variation in nutrient storage and availability, water retention and transport, and binding and stability of soil aggregates.

As the demand and needs of the population towards water is growing the value of water is felt in all sectors. At the same time, surface water resources are becoming insufficient to fulfill the water demand. So that systematic planning of groundwater improvement using modern technique is fundamental for the proper management and utilization of this precious resource.

This paper presents an integration approach involving Remote sensing / Geographic information system(RS /GIS) and hydrological models to characterized and quantify the effect of land use/ land cover (LULC) change on basin hydrology parameters. The Arc SWAT model was used daily weather and stream flow data of Upper Narmada basin from 1989 to 2011. Study evaluates change in Surface runoff, Evapo-transpiration, Total water yield, stream flow and Total aquifer recharge. Further analysis present additional evidence that changes in vegetation cover altered the hydrological response to region.

Developed model is based on digital image processing techniques under RS-GIS domain, in which conversion of Intensity, Hue and Saturation to RGB image of SWIR, NIR and red spectral bands has been applied for the signature capture of clay soils. To achieve this target, spectral enhancement process was initiated by using of AWiFS data (May, 2015). Clear cut demarcation of clay soil patches from surrounding was observed in blue tone of the converted RGB image. Out of the total geographical area, the maximum coverage of clay soils was observed in Mokama (12.79%) followed by Pandarakh (11.
