Wave energy and storm surges threaten coastal ecology and nearshore infrastructures. Although coastal structures are conventionally constructed to dampen the wave energy, they introduce tremendous damage to the ecology of the coast. To minimize environmental impact, ecofriendly coastal protection schemes should be introduced. In this paper, we discuss an example of an innovative mangrove rehabi...

Arsenic pollution in groundwater caused serious environment and health problem world widely. Few are reported for the occurrence and mechanisms of arsenic pollution in deep aquifers, though it is well documented by numerous study for arsenic enrichment in shallow groundwater. In this study, arsenic pollution was found in deep wells for drinking purpose. A total of 112 drinking groundwater sampl...

Papers published in Hydrology and Earth System Sciences Discussions are under open-access review for the journal Hydrology and Earth System Sciences Abstract Dripwater hydrology and hydrogeochemistry is particularly useful to constrain the meaning of speleothem palaeoclimate archives, for example using δ 18 O signatures. Here, we calibrate the relationship between δ 18 O in precipitation, perco...

The occurrence of in situ degradation of chlorinated ethenes was investigated using an integrated approach in a complex groundwater system consisting of several geological units. The assessment of hydrogeochemistry and chlorinated ethenes distribution using principal component analysis (PCA) in combination with carbon stable isotope analysis revealed that chlorinated ethenes were subjected to s...

Although arsenic (As) contamination of groundwater in the Bengal Basin has received wide attention over the past decade, comparative studies of hydrogeochemistry in geologically different sub-basins within the basin have been lacking. Groundwater samples were collected from sub-basins in the western margin (River Bhagirathi sub-basin, Nadia, India; 90 samples) and eastern margin (River Meghna s...

The recent increase in the incidence of deformities among natural frog populations has raised concern about the state of the environment and the possible impact of unidentified causative agents on the health of wildlife and human populations. An open workshop on Strategies for Assessing the Implications of Malformed Frogs for Environmental Health was convened on 4-5 December 1997 at the Nationa...

The data set represents the Regional Meteoric Water Line (RMWL) for Yucatan Peninsula (Mexico), a region with karstic aquifers but little knowledge of isotopic composition meteoric water. This paper comprises water collected from November 2018 to 2019 as monthly composite samples expressed weighted mean precipitation 16 locations across Peninsula. RMWL was δ2H = 7.803 δ18O + 12.075, slope and i...
