MONITORING OF SNOW RISKS BY GEO-SENSORS IN URBAN AREAS
Abstract
Monitoring of environmental components, in relation to changes in global biochemical cycles and the presence of their deposition, is one of the world`s most attractive areas of research. This area plays an important role in the sphere of crisis management. One of the dominant components of the environment is water, in all states, especially in forms of snow and ice. Monitoring of weight and height of snow deposition concentrations is the main task of research projects of envi ronmental, geographical and technical studies. These research projects try to find out how to predict the weight of snow accurately and how to predict and measure the percentage of water inside and percentage of accompanying materials. The main task is to predict the amount of water in the snow cover, based on sensors in a wireless network and small format aerial photography SFAP). The second task is to quantify the snow weight, based on collection of data using a set of mobile sensors (pH meters, conductivity meters, ultrasonic altimeter, and the conversion of height and weight in extreme conditions). Due to the increasing occurrence of the snow cover in recent years, it is necessary to dispose the technical solutions to identify and determine th e actual weight of the snow cover in relation to building (roof) safety. The method of measuring and prediction of the snow weight by using sensors is not common in the Czech Republic. This method brings new possibilities in measuring of spa tial distribution in re al time. To verify correctness of results, SFAP me thodology will be used. The scientific benefit arises from the combination of knowledge achieved by conventional field work and the visual information gleaned from SFAP. In monitoring studies, temporal changes of forms and patterns give additional clues. Connection of field data and interpretation of SFAP may lead to a deeper understanding of geo-scientific processes. Ke
