Northern Plains

The Ganges river system originates in the Central Himalayas, and extends into the alluvial Gangetic Plains and drains into the Indian Ocean at the Bay of Bengal. In the upstream mountainous regions, hydropower is the main focus of development with mega and micro projects either under construction or being planned in both Nepal and India.

After the main river channel reaches the plains, it is highly regulated with dams, barrages and associated irrigation canals. All this infrastructure development and abstractions affects the river’s flow regime and reduces flows, which, in turn, impacts downstream water availability, water quality and riverine ecosystems. Furthermore, there are concerns that climate change is likely to exacerbate the water scarcity problem in the Ganges Basin. Therefore, modeling the hydrology of the basin is critical for estimation, planning and management of current and future water resources.

This paper by the International Food Policy Research Institute (IFPRI) reviews the success of zero-tillage wheat in the rice-wheat systems of the Indo-Gange

The level of nitrate in drinking water was tested from groundwater artesian wells located within farms and surrounded by crops (mostly rice and wheat rotations).

Nitrate pollution in groundwater is associated with nitrogen loads in the environment. In urban areas, it is associated with sewage and in agriculture areas, with livestock sources and nitrogen fertiliser inputs. Nitrate pollution in drinking water can have serious health impact on humans, especially for babies and children. The most significant potential health effects of drinking water contaminated with nitrate are the blue-baby syndrome (methemoglobinemia) and cancer.

This paper in Current Science attempts to establish a missing stream link between the Markanda river and the Vedic Saraswati river in the plains of northern Haryana based on geoelectrical resistivity surveys. Resistivity surveys in the Gangetic Plains around Pehowa region in Haryana, have revealed different subsurface geological formations composed of fine, medium and coarse sand with gravel. Resistivity section between the lower part of the Markanda basin and the Saraswati river around Pehowa region indicates the presence of buried sand bodies connecting the two rivers.
