Early warning system for pluvial flooding
An early warning system for pluvial flooding caused by surface water runoff has been developed and could be implemented in the near future. The method offers greater warning and better targeting of resources. Pluvial flooding occurs when large volumes of surface water, typically from heavy rainfall, accumulate causing overland flow and ponding which is unable to drain away. Urban underground ...

New model simulates US groundwater and surface water interactions
A new model to simulate groundwater and surface water interactions has been released by the U.S. Geological Survey (USGS). The groundwater and surface water FLOW (GSFLOW) model simultaneously accounts for climatic conditions, runoff across the land surface, subsurface flow and storage, and the connections among terrestrial systems, streams, lakes, wetlands, and ground water. 'GSFLOW can be used ...

Mediterranean region: Even drier by 2100
'A new study suggests that the impact of climate change on the Mediterranean region will change precipitation and evaporation rates over land and sea, creating even drier conditions. A greater amount of atmospheric moisture will be lost from the region. Agriculture may suffer as a result, and the salinity of the Mediterranean Sea could increase. A range of climate change scenarios from the ...

The cold deep currents in the Atlantic Ocean that help shape our climate
For more than a decade scientists from the National Oceanography Centre in Southampton have been travelling to the subtropical Atlantic to collect data that provide important information about our changing climate. Just 15 miles from the sandy shores and coral reefs of the Bahamas the ocean floor plunges down to depths of over two-and-a-half miles. Along this steep slope dozens of sensitive ...

Understanding wet bulb temperatures and how it affects cooling tower performance
A cooling tower primarily uses latent heat of vaporization (evaporation) to cool process water. Minor additional cooling is provided by the air because of its temperature increase. Cooling tower selection and performance is based on water flow rate, water inlet temperature, water outlet temperature and ambient wet bulb temperature. Ambient wet bulb temperature and its affect on performance is the ...

Groundwater availability detailed in California`s Central Valley
A new, three-dimensional water-modeling tool provides a detailed picture of how water flows below ground and how it relates to surface-water in rivers and canals in California’s Central Valley. The Central Valley Hydrologic Model, developed by scientists at the U.S. Geological Survey, is available for use by water managers and other agencies. The model was designed to help resource agencies ...

Innovation in scum removal
Nowadays de-nitrification brings an increasing amount of surface scum to wastewater treatment processes. In rectangular sedimentation tanks where surface scum skimming is realised with a scum pipe, the amount of water needed to carry the scum in the pipes is approximately five times greater than that required by the new surface scum removal system introduced by Finnchain Oy of Rauma, Finland. 80% ...
