UPSCAPE: A scientific approach to better water management in the Cauvery River Basin

In an effort to make water resources sustainable, the Ministry of Earth Sciences, India and the Natural Environment Research Council (NERC), UK have funded a new project “Upscaling Catchment Processes for Sustainable Water Management in Peninsular India” (UPSCAPE). It is a 3-year £2 million research project that is one of the three projects in India initiated under the ambitious Newton-Bhabha Sustaining Water Resources Programme. Six institutes have come together as partners in this project, of which the prestigious Indian Institute of Science, Bangalore, is the lead Institute from India. “The motivating factor of the Newton-Bhabha project is to ensure science reaches the society and benefits it”, says Prof. Pradeep Mujumdar, Chairman at the Interdisciplinary Centre for Water Research, Indian Institute of Science. He also leads the team of Indian scientists working on the UPSCAPE project in the Cauvery river basin.

Towards a Clearer Picture in Biomedical Imaging: An Improved Algorithm for Photo Acoustic Tomography

In a collaborative study between the Indian Institute of Science (IISc), Bangalore, and the University of Twente, The Netherlands, researchers have designed a new algorithm for image recovery in Photoacoustic Tomography (PAT). PAT is an important non-invasive biomedical imaging technique where the optical contrast rendered by laser beams and the superior resolution of ultrasound waves are used to study biological tissues. The new algorithm works better with higher accuracy as compared to the conventional ones in use today.

Bangalore’s youth aim buying a car as soon as possible, reveals study

One might think that driving a car in Bangalore can easily become a nightmare, thanks to the traffic! But a recent study by a team of researchers at the Indian Institute of Science, Bangalore, and M. S. Ramaiah Institute of Management, Bangalore have found that 62% of young adults in Bangalore aspire to own a car as soon as they can afford one. The team, lead by Prof. Ashish Verma from the Department of Civil Engineering, studied the attitudinal factors that influence car ownership decisions among urban young adults in a developing country like India.

The 2015 Chennai floods – A rapid assessment

In December 2015, Chennai witnessed massive floods killing about 400 people and displacing thousands. Now, researchers from Interdisciplinary Centre for Water Research (ICWaR) at the Indian Institute of Science, Bangalore, in collaboration with researchers from Indian Institutes of Technology (IITs), Madras and Bombay have assessed the flood related information in the public domain and data from secondary sources and carried out quick first level analyses to develop an understanding about possible reasons for the floods. They observed that the massive floods were a result of a combination of factors; high rainfall intensity, overflowing rivers, global climate drivers, unplanned urbanization, inadequate drainage system and upstream reservoir releases.

Scientists design new methodology to better predict Land Surface Temperature under cloudy conditions

Measurement of Land Surface Temperature (LST) is important for hydrology, environment science and many associated fields. Prof. D. Nagesh Kumar of Department of Civil Engineering at the Indian Institute of Science, Bangalore, and his team have proposed a novel methodology that can accurately predict LST at high resolution even under cloudy conditions. Their work has been published in the ISPRS Journal of Photogrammetry and Remote Sensing.

Why Bangaloreans just don’t want to cycle.

A bicycle is budget friendly, being cheaper than most other forms of transport, eco-friendly requiring absolutely no fuel, does not need​ much of parking space, helps keep the chic city-dweller fit without having to shell out for monthly gym subscriptions, and requires a very low maintenance. Put like that, it sounds like an ideal mode of transport. And yet, for most of us having owned a bicycle during our childhoods, a cycle is only a symbolic reminiscent of the adventures of our junior years and nothing more.

Novel methods for better flood prediction

Prediction of rainfall and flood is very important for densely populated country like India. Scientists at the Indian Institute of Science (IISc), Bangalore have proposed a new method for predicting flood magnitude, which is more effective than conventional methods. The team consisted of Prof. V.V. Srinivas and Dr. Bidroha Basu of Department of Civil Engineering.

Landfill leachate posing threat to the environment: Study

A new study at the Indian Institute of Science, Bangalore, has found that leachate from landfills is posing a major threat to the environment. Leachate is a contaminated liquid that drains through the bottom of the solid waste disposal facilities such as landfills. It contains numerous dissolved and suspended materials. These materials have a high value of Leachate Pollution Index (LPI) and pose a threat to the environment and human health.

Developing algorithms for better water resource management

Scientists at IISc may have the solution to one of the major problems faced in our country – water resource management. By applying a technique called the 'Multi-criteria Decision Making' they are trying to address various water management and irrigation challenges.
