Abstract

The rural development grants - among others - help to promote the competitiveness of the agricultural activities. Plantations take great interest in the southeastern part of Hungary. Farmers need to make soil tests before plantation of fruit and grape. We investigated the distribution of the main physical characteristics in this area. For the establishment of vineyards, the areas were adequate according to the pH, and salt content. The results of the soil tests show some strong relationships between the determined physical parameters.

Abstract

To guarantee food security and job creation of small scale farmers to commercial farmers, unproductive farms in the South 24 PGS, West Bengal need land reform program to be restructured and evaluated for agricultural productivity. This study established a potential role of remote sensing and GIS for identification and mapping of salinity zone and spatial planning of agricultural land over the Basanti and Gosaba Islands(808.314sq. km) of South 24 PGS. District of West Bengal. The primary data i.e. soil pH, Electrical Conductivity (EC) and Sodium Absorption ratio (SAR) were obtained from soil samples of various GCP (Ground Control Points) locations collected at 50 mts. intervals by handheld GPS from 0–100 cm depths. The secondary information is acquired from the remotely sensed satellite data (LANDSAT ETM+) in different time scale and digital elevation model. The collected field samples were tested in the laboratory and were validated with Remote Sensing based digital indices analysisover the temporal satellite data to assess the potential changes due to over salinization. Soil physical properties such as texture, structure, depth and drainage condition is stored as attributes in a geographical soil database and linked with the soil map units. The thematic maps are integrated with climatic and terrain conditions of the area to produce land capability maps for paddy. Finally, The weighted overlay analysis was performed to assign theweights according to the importance of parameters taken into account for salineareaidentification and mapping to segregate higher, moderate, lower salinity zonesover the study area.

Abstract

This paper concerns the possibility of using AGS15 capacitive inclinometers in the geodetic monitoring of slender structures. The basics of geometric monitoring have been introduced, and the features of inclinometers that can be used in these studies have been described. Main expectations towards them have been formulated. Three tests were conducted: (1) a few days' stability test of readings, (2) the test of inclinations controlled tachimetrically and (3) continuous survey of a physical object. It has been found that in order to obtain satisfactory results it is necessary to correct the readings due to the drift and the effect of temperature. The works conducted as part of described project work are not capable of identifying those indicators. To achieve them there were designed the system that support the acquisition and processing of the measurement and also the collection and transmission of results. In the conclusions authors stated that inclinometers AGS15 can be suitable for monitoring, but the works aimed at improving their performance should be undertaken.

, earthquake hazards in the area of San Andreas Fault System are assessed from fault slip rate estimates. However, the estimates of slip measured by the long-term offset of physical geologic features do not always match modern estimates from precise positioning GPS measurements, model simulating interseismic strain accumulation, historical earthquake ruptures, and postseismic stress relaxation over several hundred years and slip rates evaluated from geological data and GPS rate measurements can improve the understanding of earthquake mechanisms and reduce risk (Mc
