Hydrologic sensitivity of flood runoff and inundation: 2011 Thailand floods in the Chao Phraya River basin

The Thailand floods in 2011 caused unprecedented economic damage in the Chao Phraya River basin. To diagnose the flood hazard characteristics, this study analyses the hydrologic sensitivity of flood runoff and inundation to rainfall. The motivation is to address why the seemingly insignificant monsoon rainfall, or 1.2 times more rainfall …

Agriculture intensifies soil moisture decline in Northern China

Northern China is one of the most densely populated regions in the world. Agricultural activities have intensified since the 1980s to provide food security to the country. However, this intensification has likely contributed to an increasing scarcity in water resources, which may in turn be endangering food security. Based on …

Groundwater prospecting in Deccan traps covered Tawarja basin using Electrical Resistivity Tomography

Tawarja river basin is in drought prone Latur district of India falling in basaltic Deccan …

Assessment of hydroclimatic condition in extensive groundwater mining area, Southern India

The study highlights the climatic water balance, drought assessment and agricultural potentiality of Uppar Odai sub-basin located in the Southern part of India, Tamil Nadu state. The average annual precipitation in the sub-basin is 625 mm, which is much lower than the state average rainfall (970 mm). It has been …

Assessment of snowmelt runoff in the eastern Himalayan region under climate change scenarios

In Eastern Himalayan region, snow melt is the major source of fresh water. Also, snow covered areas lying at low altitudes are expected to be most vulnerable to global warming. Thus, assessment of the snowmelt runoff under different climatic scenarios is important for efficient management and planning of water resources, …

Uncertainty in global groundwater storage estimates in a total groundwater stress framework

Groundwater is a finite resource under continuous external pressures. Current unsustainable groundwater use threatens the resilience of aquifer systems and their ability to provide a long-term water source. Groundwater storage is considered to be a factor of groundwater resilience, although the extent to which resilience can be maintained has yet …

Changing pattern of heavy rainstorms in the Indus basin of India under global warming scenarios

Estimation of extremely high rainfall (point or areal) is one of the major components of design storm derivation. The estimation of Probable Maximum Precipitation (PMP) involves selection of heavy rainstorms and its maximization for the moisture content during the rainstorm period. These heavy rainstorms are nothing but the widespread heavy …

Incorporating local institutions in irrigation experiments: evidence from rural communities in Pakistan

Many irrigation systems are special cases of common-pool resources (CPRs) in which some users have preferential access to the resource, which in theory aggravates collective action challenges such as the under-provision of necessary infrastructure as a result of unequal appropriation of water resources. We present experimental evidence based on an …

Report on Tawang river basin study: cumulative impact assessment of proposed hydel power projects, determination of basin carrying capacity, and landscape level biodiversity management plan

While considering the accordance of forest clearance for 750 MW Tawang-I and 750 MW Tawang-II projects, the Forest Advisory Committee (FAC) of the Ministry of Environment and Forests, (MoEF and CC) asked the Government of Arunachal Pradesh to conduct a study on Tawang river basin with the following objectives: To …

The power of rivers: finding balance between energy and conservation in hydropower development

The Nature Conservancy’s white paper, “The Power of Rivers: Finding balance between energy and conservation in hydropower development,” addresses the global expansion of hydropower dams and the need to find development scenarios that provide energy, but also work for communities and nature. Designed as a resource for hydropower companies, governments, …

This information is presented in five sections. Following the Introduction, Section 2, Flood Practices, summarizes international best practice and flood management …

Revitalizing the Ganges coastal zone: turning science into policy and practices

The Ganges coastal zone of Bangladesh and West Bengal, India, is characterized by extremes in terms of both challenges and opportunities. Despite the huge investment in the coastal zone over the past 50 years, the poverty of farming families in the region remains extreme. The CGIAR Challenge Program on Water …

The Rajasthan River Basin and Water Resources Planning Act, 2015

An Act for the establishment of State Water Resources Advisory Council and Rajasthan River Basin and Water Resources Planning Authority to adopt an Integrated Water Resources Management approach for management and development of river basins and sub-basins on sustainable basis by planning of all watershed, irrigation and drinking water projects …

Stochastic approach to analyzing the uncertainties and possible changes in the availability of water in the future based on a climate change scenario

The objective of this study was to analyze the changes and uncertainties related to water availability in the future (for purposes of this study, it was adopted the period between 2011 and 2040), using a stochastic approach, taking as reference a climate 5 projection from the climate model Eta CPTEC/HadCM3. …

Securing water, sustaining growth

Water insecurity costs the global economy some US$ 500 billion annually, according to Global Water Partnership (GWP). That figure does not take into account environmental impacts so the total drag on the world economy could be 1% or more of global Gross Domestic Product (GDP). GWP released these figures based …
