Design Of An Instrumentation System To Record Distribution Profile Of Snow Layer Temperature For Modelling Of Snow Avalanche Forecast, Raman Attri
Raman K. Attri
The measurement of snow hydrological parameters is extremely important in developing a model for the predication of Snow avalanche as well as Snowmelt water in the rivers. When direct measurement of these parameters is practically difficult, its dependence on snow temperature is used to develop snow cover models. A robust model for avalanche forecasting requires a sophisticated instrumentation system which can measure the required temperature parameters at right data points within snow pack. A Snow Temperature Profile Sensing System along with Surface temperature Sensor has been designed to measure Snow temperature gradient, temperature distributions, and average temperature of snow pack, …

Implementation Of Linear Array Of Ultrasonic Transmitter-Receiver Transducers For Detection Of Non-Smooth Porous Surface, Raman K. Attri, Swaranjit Singh
Raman K. Attri
Level measurements, thickness measurement or remote surface detection using ultrasonic pulse transit method require that the target surface be at 90O to the incident beam so that reflected beam comes back at 180O angel to effectively use this method. This is perfectly true in case of flat, solid surface at right angle to the incident beam. But surface irregularities of a porous, non-smooth, uneven material such as snow cause penetration of incident wave into the surface, absorption of the incident energy, scatter of energy in many directions and further attenuation of reflected signal making it difficult to detect the reflected …

Gsis: A Conceptual Model For Web-Based Integration Of Information Technology With Geo-Scientific Instrumentation, Raman Attri

Since a long time leading organisations have been advocating the need of implementation of IT in a centralised manner on the distributed geological data monitoring centres. In the era of IT, it is highly important to access, share and analyse related data on a common platform for fast retrieval of information in centralised as well as in distributed mode. In this article a concept to integrate Geo-Scientific Instrumentation systems to Information Technology has been highlighted. The vision to create a Geo-Scientific Information System (GSIS) would be an approach where a centralised web-enabled database of the data acquired & transmitted by …
