Climate Change and Hydrology in Indian Perspectives

Ansar Khan*, Soumendu Chatterjee

The global hydrological cycle is a key component of Earth’s climate system. A significant amount of the energy the Earth receives from the Sun is redistributed around the world by the hydrological cycle in the form of latent heat flux. Changes in the hydrological cycle have a direct impact on droughts, floods, water resources and ecosystem services. Observed land precipitation and global river discharges do not show an increasing trend as might be expected in a warming world.

Seasonal Variation of Water Chemistry of Panchpokhari: a Case Study of an Alpine Lake Series in the Central Himalayas

Rosha Raut*, Roshan M. Bajracharya, Subodh Sharma, Chhatra M. Sharma, Bhawani S. Dongol

Panchpokhari (five lakes) is a well-known alpine lake series which includes five lakes situated at an elevation of 4160 masl. in the Sindhupalchowk district of Central Nepal. The lake series has vital socio-cultural, religious and environmental significance and provides habitats for highly sensitive aquatic biodiversity. The present research was carried out with the aim of assessing detailed water characteristics and its implications for the lake environment of Panchpokhari and which is a part of detailed investigation of lake series.

Clean Water, Healthy Environment, and Preservation of Watersheds: Correct, Enforceable Policies are Essential

Shehani A. Wimalawansa, Sunil J. Wimalawansa*

Globalization and industrialization have a marked effect on water and food security, with both beneficial and detrimental effects on water and air quality and living standards, especially in emerging economies. Air pollution is visible and relatively easier to control with enforcement of legislation, but water pollution is insidious and easily goes undetected. Contamination of food and water can have potentially deadly consequences, but many of these are preventable if proactive actions are taken.

Spatial Variation in Arsenic Concentration in the Groundwater of Nawalparasi District, Terai Nepal

Ishwar Chandra Yadav*, Ningombam Linthoingambi Devi

The spatial variability of arsenic (As) in the groundwater was studied in the three villages of Nawalparasi district, Nepal. The average concentration of As varied as low (0.16mgL-1) in Kasiya to high (1.34mgL-1) in Thulokunwar with all the tubewells exceeding WHO (0.01mgL-1) and NIS (0.05mgL-1) limits for drinking waters. The concentration of As was varied even in closely located tubewells suggesting the possibility of spatial variation due to some conditions such as latitude, longitude and depth of tubewell. The As level also varied inversely with the depth of tubewells.

Mountains and Rivers: Impacts of and Responses to Flash Flood in the Seti River in Nepal

Chhatra Mani Sharma*, Megh Raj Dangal, Neera Shrestha Pradhan, Renu Kumari Thapa Lama, Sundar Kumar Rai

On 5 May 2012, a flash flood originating in the Seti river swept away Kharapani, a settlement also known as Tatopani in Sardikhola Village Development Committee (VDC), killing people and destroying the lives and livelihoods of people living and working along the river. This paper explores the perceptions and responses of flood affected people. It also looks at the impacts of the flood on people’s livelihoods and their short-term and long-term strategies for coping with and adapting to the destruction caused by the flash flood.

Assessment of Groundwater Quality in Far Western Kailali District, Nepal

Smriti Gurung*, Nani Raut, Sangeeta Shrestha, Janita Gurung, Biboss Maharjan, Subina Shrestha

Drinking water quality parameters from groundwater source was assessed in Bhajani and Chuha VDCs in Kailali district. A total of 24 groundwater samples were assessed following standard procedures and the results were compared with the national standard. Most of the parameters such as colour, pH, turbidity, TDS, EC and total hardness were within the prescribed limit. Some heavy metals such as Al, Pb, Cd, Fe, As and Mn exceeded in some of the samples indicating possible risk to the community.
