Fertile farmlands in Cauvery delta: evolution through LGM

The Cauvery delta encompasses legendary farmlands for at least over the last 2300 years BP that had supported the growth of the famous Chola and Pandya kingdoms. The chrono-stratigraphic study from six sediment cores taken from the Cauvery basin indicates Holocene evolution of the present delta in response to past …

Environmental implications of Pancheshwar dam in Uttarakhand (Central Himalaya), India

The present study outlines major concerns and potential environmental consequences of the proposed Pancheshwar high dam in Uttarakhand (Central Himalaya), India. We evaluate the risks associated with the project in the light of environmental impact observed for the Tehri project in the region and the geological understanding developed over the …

Unpacking transformation: a framework and insights from adaptation mainstreaming

This paper contributes to improving understanding of how funders, practitioners and other stakeholders can support and facilitate transformation in adaptation to climate change. It uses the latest academic literature, as well as learning from practice, to put forward a conceptual framework for determining the likelihood of an adaptation initiative delivering …

Geochemistry of sandstone type uranium deposit in Tarat formation from Tim-Mersoi Basin in Northern Niger (West Africa): Implication on Provenance, Paleo-Redox and Tectonic setting

The study aimed at investigating the geochemistry of a sandstone-type uranium deposit in Tarat formation for provenance, paleo-redox, tectonic setting in order to propose a geological model of uranium. X-Ray Fluorescence (XRF) and Induced Coupled Plasma Mass Spectrometry (ICP-MS) analyses were used to determine the sandstone composition. Original Source

Integrated hydrological data book 2018

The present issue of the data book provides updated basin/site-wise data of river basins (Region-III) covering aspects such as location, drainage area, temperature, average runoff, seasonal water flow, historical water levels, average sediment load, water quality parameters and land use statistics.

Compendium on silting of reservoirs in India

The Central Water Commission’s compendium on silting of reservoirs in India in 2015 had shown that Tungabhadra dam was the second most affected dam in the country after the massive Bhakra dam in Punjab. While the last survey of the silt in the dam was conducted in 2008, extrapolation by …

Global estimate of submarine groundwater discharge based on an observationally constrained radium isotope model

Along the continental margins, rivers and submarine groundwater supply nutrients, trace elements, and radionuclides to the coastal ocean, supporting coastal ecosystems and, increasingly, causing harmful algal blooms and eutrophication. While the global magnitude of gauged riverine water discharge is well known, the magnitude of submarine groundwater discharge (SGD) is poorly …

Guidelines for sediment management in hydropower and water resources projects

Reservoir sedimentation has been a pertinent issue for diversion structures for a very long time. Sedimentation of reservoirs pose problems like loss of live storage, erosion and turbine coating, frequent shutdown of power due to maintenance of hydraulic machinery etc. Considering the need of the hour to address these issues, …

Natural infrastructure in São Paulo’s water system

Healthy forests act as natural infrastructure by filtering water and buffering against the impacts of floods and droughts. Although these benefits are widely known, they have rarely been presented in a way that is actionable for decision-makers – such as utilities, water agencies, and companies – to prioritize investing in …

Comparative assessment of micro-watershed silt load with morphological parameters to evaluate soil conservation strategies

The comparative assessment of morphologic runoff and annual silt load from micro-watersheds can help in establishing relationships between these parameters with objectives of controlling runoff, conservation of soil, reduction of reservoir silt load and enhanced groundwater resources in the micro-watersheds. The automated watershed delineation technique using the filled digital elevation …

Framework for upstream-downstream linkages of land and water management in the Hindu Kush Himalaya (HKH) Region

This paper develops a conceptual and generic framework design for the study of upstream-downstream linkages (UDL) in the Hindu Kush Himalaya (HKH) region. The framework application will to define changing upstreamdownstream linkages (UDL) and likely impacts on downstream regions. The results of such applications will be useful for policy makers, …

The deep sea is a major sink for microplastic debris

Marine debris, mostly consisting of plastic, is a global problem, negatively impacting wildlife, tourism and shipping. However, despite the durability of plastic, and the exponential increase in its production, monitoring data show limited evidence of concomitant increasing concentrations in marine habitats. There appears to be a considerable proportion of the …

Monitoring and assessment of water health quality in the Tajan River, Iran using physicochemical, fish and macroinvertebrates indices

Nowadays, aquatic organisms are used as bio-indicators to assess ecological water quality in western regions, but have hardly been used in an Iranian context. We, therefore, evaluated the suitability of several indices to assess the water quality for an Iranian case study. Original Source

Are alien fish a reliable indicator of river health?

The ability of many introduced fish species to thrive in degraded aquatic habitats and their potential to impact on aquatic ecosystem structure and function suggest that introduced fish may represent both a symptom and a cause of decline in river health and the integrity of native aquatic communities. The varying …

Freshwater biodiversity in the Lake Victoria Basin

The Lake Victoria Basin is internationally recognised for its high freshwater species diversity and endemism, which are of critical importance to local livelihoods and national economies within the basin. However, freshwater ecosystems within the region are highly threatened, with current safeguards proving inadequate and the focus of much past and …

Assessment of eco-environmental geochemistry of heavy metals pollution of the river Gandak, a major tributary of the river Ganga in Northern India

This study includes a seasonal analysis of sediment contamination of the River Gandak by heavy metals. It passes through the many small, medium and big cities of Uttar Pradesh and Bihar in Indian Territory. To explore the geochemical condition of the streambed sediment of the river, seven heavy metals, namely …

The wood-boring trace fossil Asthenopodichnium from Palaeocene sediments of the Barmer Hill Formation, western Rajasthan, India

The present study documents the wood-boring trace fossil Asthenopodichnium from the Palaeocene sediments of the Barmer Hill Formation (BHF) in the Barmer Basin, Western Rajasthan, India. The Asthenopodichnium trace fossils are loosely to tightly packed, pouch-like burrows or almond-shaped structures identified as Asthenopodichnium lignorum, whereas lozenge and J-shaped structures are …

Convergent evidence for widespread rock nitrogen sources in Earth’s surface environment

Nitrogen availability is a pivotal control on terrestrial carbon sequestration and global climate change. Historical and contemporary views assume that nitrogen enters Earth’s land-surface ecosystems from the atmosphere. Here we demonstrate that bedrock is a nitrogen source that rivals atmospheric nitrogen inputs across major sectors of the global terrestrial environment.
