Assessment of Decadus Terminus Position changes & Ice thickness measurement by RIS Plus GPR for Menthosa Glacier

RIS Plus GPR is used to assess ice thickness of Menthosa glacier for water reserve stored in glacier as well as to comprehend the future of glacier evolution in response to simulated climate change scenarios.Since last 5 decades, studies were based on 2-dimensional glacier changes ( changes in area & length of glacier) that only provide the rough approximation of climate change.In recent years Remote Sensing Modelled Based Method were also used to determine the ice thickness of glacier across Himalayan region & due to low resolution dataset, data gap, averaging effect & post processing limitation the output data was not reliable.To remove the substantial gap in glacier study & in order to get the accurate information about climate change, GPR based ice thickness measurement was required.Thus, RIS PLUS , the most compact and lightweight GPR supported by antennas operating in 25 MHz to 2.6 GHz frequency range was supplied to assess the ice thickness for glacier study.The RIS Plus Ground Penetrating Radar system used for the present study is comprised of unshielded antennas, transmitter (Tx) and receiver (Rx), one fast-wave control unit (DAD), battery, network cable and a Toshiba laptop for data visualization, storage and processing. Before starting the survey, the ...

Mapping of Underground Utilities

As built maps of utilities are made in reference to specific points, which become null and void as the civic layout changes. Most times, such maps do not even exist. The utilities are often confronted with the task of ensuring expansion of buried services, without knowing the locations or routes of their utility assets. The contractor is bestowed the responsibility to execute the work of new installation of cables or pipes or even over ground structures such as fly over�s, freeways or buildings without damaging existing buried cable and pipe utility services. The task faced by the contractor (or the user i.e the utility itself) is applicable to all types of utilities and especially buried utilities such as water pipes, sewer pipes, power cables etc. The onus of avoidance of buried utilities is of the contractor. Many a contractor recognize that they are faced with the task of mapping a jungle of underground utilities, that are a result of decades of installation of buried services such as sewer, water, power etc independently and without� correlation to each other, as they were and are installed under tender or contract for installation of services for that specific user alone for example a telco, ...

When is a ground penetrating radar beneficial in locating of underground pipes & cable utilities ?

The task of Locating underground utilities can be bifurcated into two deliverable: 1.Detection of underground utilities 2.Mapping of underground utilities If we take a this can be further subdivided into: a. Detection of metallic cables & pipes, whether energized current carrying utilities or non energized utilities such as signaling cables, metallic pipes etc. b. Detection of DI pipes, metallic manholes etc. c. Non metallic HDPE telecom pipes, fiberglass manholes, etc. Underground cable & pipe utility locating requires the use a combination of various equipments and techniques which need to be chosen based on desired deliverables and then correctly employed to obtain the desired results. If the answer is a , an operator with basic training on usage of the ever dependable CSCOPE DXL2 Cable avoidance tool or CAT33XD Cable avoidance tool, can do the job blindfolded. If the answer is b, an additional metal detector &/or magnetic locator is required. If the answer is c. The use of a ground penetrating radar or GPR is necessary. In layman term, Fundamentally, both a and B operate on the principle of detecting electromagnetic energy (based on specified frequencies) . In case of CSCOPE Pipe & Cable locator standard features include capability to detect both 50Hz passive power signal frequency and ...
