2. FLOOD ESTIMATION IN MIXED/URBAN/RURAL/ CATCHMENTS OF SOUTH INDIA


Ministry of Water Resources, Government of India has sanctioned a project titled “Flood Estimation in Urban/Rural/Mixed Catchments in South India” to Dr.S.Ramaseshan (former visiting faculty) (Principal Investigator) and Mr.K.Srinivasa Raju, Lecturer (Co-PI) at a cost of 22.21 lakhs in January 2006.

The research project aims at study of rainfall-runoff relationship in a urban and semi-urban catchments and simulation the process to derive flooding patterns in the catchments. Thematic layers affecting runoff process were generated from satellite imagery and ancillary data for a catchment near Chennai. Rainfall and Runoff measured for Adyar River was collected and will be used for calibration and validation of model to be developed in MIKE21 software environment. The model helps in quantifying the flooding of the catchments for various scenarios of rainfall and landuse conditions. High Resolution spatial databases were developed. The validation of model is under progress.

3. SPACE BASED INFROAMTION SUPPORT FOR DECENTRALZED PLANNING (SIS–DP)


There is a need now to provide information in the form of atlas, so that the decision or planning of activities can be taken up in more scientific and timely manner. In this, spatial planning is the need of this hour with the proven space based data products and information processing techniques such as GIS. Here, Spatial information – images and maps form the basis for most of the planning and developmental activities.

The project SIS- DP aims at strengthening the local body with basic resource information as geo databases (in map form) and appropriate dissemination mechanism as required by the developmental and implementing agencies. Considering the potential of GeoICT in supporting such valuable information processing and archiving and dissemination, the Space based Information Support for Decentralized Planning (SIS_ DP) has been launched by NRSC/ ISRO as a coordinating agency. The goal of this project is to develop a platform of a GeoICT and to engage local bodies for carrying out their developmental activities in a decentralized, timely and transparent manner. The outcomes are expected to be shared with the stake holder state departments for effective use.

Spatial depiction of land & water resources along with their attribute information for preparation of District Resource Geospatial Atlas keeping village Cadastral data as base in a virtual and seamless manner for entire country. Development of software tools and utilities (including web based GIS applications and standalone) for providing multipurpose user driven applications for speedy, accurate and transparent decision making for district planning; and Capacity building in state departments along with training of manpower and capability for spatial data analysis, which will maintain updates & manage data bases for decentralized planning.

5. MAPPING OF INDICATORS OF DESERTIFICATION USING RISAT SAR DATA AN EVALUATION


Desertification, as defined by UNEP (United Nations Environmental Programme) in 1992 and adopted by United Nations Convention to Combat Desertification (UNCCD), is the “Land degradation in arid-, semi-arid and dry sub humid areas resulting from various factors, including climatic variations and human activities”. The causes of desertification are: change in frequency and amount of rainfall, dwindling vegetal cover and groundwater table, wrong management practices, over – exploitation of the land resources, excessive grazing etc. Desertification has been recognized as a major global environmental concern, affecting 250 million people directly and with over one billion (more than one – fifth of the world’s population) at risk. Approximately 3 percent of the world’s drylands are irrigated, 9 percent are rainfed cropland, and 88 percent are rangelands.

The most significant process of desertification/land degradation in this state is vegetal degradation (2.65 percent), followed by water erosion (0.73 percent) and manmade (mining) 0.05 percent).Remote sensing is the science and art of obtaining information about an object, area or phenomenon through the analysis of data acquired by a device that is not in contact with the object area or phenomenon under investigation. The main objective of this project is to prepare desertification status map using RISAT data in Theni district of Tamilnadu. The major advantage of utilizing the microwave backscatter values for understanding the terrain and use of imaging radars for estimating the terrain parameters is due to its ability to image day and night and under all conditions of weather. Furthermore, microwave remote sensing is successful in sensing hilly areas, dense forests including regions under constant cloud cover.

Tamil Nadu is the southernmost state of India According to 2001 the population density is 478, sex ratio is 986 and literacy is 73.47 percent. The main objective of this project is to prepare desertification status map using two different years satellite data (LISS III) on 1:50,000 scale for Dharmapuri, Theni, Tirunelveli, Virudhunagrar of Tamilnadu State and preparing of 1: 0.5 million scale map using latest AWiFS data for entire state of Tamilnadu and Kasargodh, Palakad of Kerala State.

12. ASSESSMENT AND MONITORING OF LAND USE CHANGES WITH SPECIAL REFERENCE TO SOLAR SALTPANS


Tamil Nadu is the second largest producer of salt, next to Gujarat. Thoothukudi and Nagapattinam are the two major salt producing districts of Tamil Nadu, accounting for about 80% of the State’s salt production. Solar salt production activities have resulted in changes in Land use / Land cover along the coast of Tuticorin. Its impact on environment is significant on ecological and socio – cultural terms. Much of the saltpan areas in the Tuticorin coast have been replaced by urban settlement, decreasing livelihood opportunities to the coastal folk. The objectives of the project is to asses and monitor the land use changes for past 20 years with special reference to salt production in around Tuticorin coast. The changes in land use map of present will compare with the years 2003 and 1993. Impact of ground water quality will be studied due to changes in land use pattern for two decades. Questionnaire sample survey have been carried out among the salt workers , salt owners in Tuticorin and Vilathikulam taluk to study the socio economic status, while survey on water quality carried out in urban areas of Tuticorin corporation. The project work is in progress and the preparation of land use map is nearing in completion. The out put will be used by the user departments.
