Water and a City: Institutions, community and citizens at work in Bengaluru

Presently, the Cauvery River is the city’s sole water source located at a distance of 100 km. But with a population expected to reach 20 million by 2031, the rising demand for water presents unique challenges, calling for participation at all levels.

Hydrogeology in Strategic Water Conservation

Conventional approaches to conservation of groundwater have not considered the need to involve an understanding of aquifer measurement and hydrogeology. Considering India’s diverse geography, it is pertinent to develop a scientific understanding of underlying geology of groundwater resources and how aquifers work.

Water conservation and community responsiveness

In colonial India, water ownership became entrenched with the State, a practice that continued post-Independence. For ensuring sustainable and assured supply addressing the needs of communities, decentralised practices such as rainwater harvesting can be beneficial.

Managing waters in India’s varied ecological zones

It is IRONIC that the Himalaya, often alluded to as the ‘water tower of Asia’—the source of mighty rivers that support millions, now face stress especially during summers. The rapidly reducing flow in surface drainage and the disappearance of springs are signs of looming disaster. Changes in micro-climate, anthropogenic pressures, infrastructure development, increase in the consumption and use of water, a reduction in vegetation cover—particularly diverse forests and pastures with mixed species...

The Study of River Morphology

River morphology is a scientific field that concerns with changes in river forms in plan and cross-sections that result because of erosion and sedimentation processes. The principal elements are the dynamics of sediment transport and river flow. Studies on the river morphology provide important information required for the management of water resources, constructions along the river banks and in mitigating hazards such as floods, etc (Sarkar, 2016). Approaches to Studies on River Morphology in India India...

The Concept of Environmental Flow and Sustainability

Minimum ecological flow is based on the principle that a certain amount of minimum flow must be present in a flowing freshwater ecosystem such as a river or an estuary so that the ecological quality of the flowing freshwater ecosystem is maintained. The term minimum ecological flow is also used sometimes, in association with the term environmental flow that denotes the amount of water running in a flowing freshwater body that can keep the water body at a desirable environmental condition. The Concept...

Global Warming and Impacts of Glacial Meltdowns on Indian Rivers

Other the polar regions, the Himalayas follow as the largest deposit of frozen water in the world, especially in the case of Himalayan glaciers. Himalayan glaciers make up about 17 per cent of the Himalayas and about 37 per cent of the Karakoram Range. The water melted from Himalayan glaciers form the headwaters for many major river catchments in the Indian subcontinent. This discharge of headwater makes up for about 70 to 80 per cent of the melting of snow and ice from the highlands. In such a scenario,...

Climate Change Severe Threat to Himalayan Glaciers

Many studies on wastage of Himalayan glaciers have come to the conclusion that Himalayan glaciers are retreating with varying rates of retreat between individual glaciers. This glacial retreat can vary between a few meters to up to 61 m/year. Also, mapping carried out of an area of about 11,000 sq km out of 40,000 sq km of glaciated area revealed that about 13 percent of the area has been lost in the last 4 to 5 decades (Kulkarni & Karyakarte, 2014). In this wastage of Himalayan glaciers or a negative...
