California’s primary hydrologic system, the San Francisco Estuary and its upstream watershed, is vulnerable to the regional hydrologic consequences of projected global climate change. Previous work has shown that a projected warming would result in a reduction of snowpack storage leading to higher winter and lower spring-summer streamflows and increased spring-summer salinities in the estuary. ...

Although arsenic contaminated groundwater in Bangladesh is a serious health issue, little is known about the complex transient patterns of groundwater flow that flush solutes from aquifers and carry solutes into the subsurface. Hydrologic modeling results for our field site in the Munshiganj district indicate that groundwater flow is vigorous, flushing the aquifer over time-scales of decades to...

Discovering and accessing hydrologic and climate data for use in research or water management can be a difficult task that consumes valuable time and personnel resources. New advances in cyberinfrastructure and in semantic mediation technologies have provided the means for creating better tools supporting data discovery and access. In this paper we describe a freely available and open source so...

Floods are among the most catastrophic natural disasters around the globe impacting human lives and infrastructure. Implementation of a flood prediction system can potentially help mitigate flood-induced hazards. Such a system typically requires implementation and calibration of a hydrologic model using in situ observations (i.e., rain gauges and stream gauges). Recently, satellite remote sensi...

Highly concentrated precipitation during the rainy season poses challenges to South Korean water resources management in efficiently storing and redistributing resources. Under new climate regime, is likely become more challenging with regards water-related disaster risk deterioration of quality. To alleviate such issues by adjusting plans, this study examined impact change on streamflow Bocheo...

Climate change impact on water resources (streamflow and deep natural recharge) based on the downscaled outputs from the ECHAM5 general circulation model (GCM) has been investigated in the Mediterranean basin (Fluvià, Spain) for the A2, B1 greenhouse scenarios and 2000–2024/2025–2050 time slices. The HEC-HMS 3.4 rainfall-runoff numerical model was the basic tool used to generate streamflow for ...

The Kabul River, while having its origin in Afghanistan, has a primary tributary, the Konar which originates Pakistan and enters Afghanistan near Barikot-Arandu. River then re-enters Laalpur, making it true transboundary river. catastrophic flood events due to major snowmelt Hindu Kush mountains occur every other year, inundating many urban centers. This study investigates risk under 30 climate...
