Overview
The Global Water Flow Probe Replacement Computer receives an electrical signal from the propeller, amplifies the signal, and converts the reading to feet per second (or meters per second, depending on programming). The large LCD screen displays average, minimum, and maximum water velocity readings.
Applications
Up to 30 sets of minimum, maximum, and average data readings can be stored in the water velocity computer. These data points can be reviewed on the computer screen for later analysis. The water velocity computer has a water-resistant housing and incorporates a unique four-button operation for changing functions and resetting the display. The water velocity computer is powered by a non-replaceable battery that will last approximately five years with normal use. Low battery warnings will also display as appropriate.

Rounded pebbles give evidence of past flowing water on Mars
NASA's Curiosity rover has found pebbles that appear to have been rounded by streamflow, according to a release from University of California Davis. Experts say the finding represents the first on-site evidence of sustained flowing water on Mars. 
 The rounded pebbles discovered are only known to form when transported through water over long distances. Their discovery supports theories that the red planet could once have supported life. 
The smooth rocks were found between the north rim of the planet’s Gale Crater and the base of Mount Sharp, a mountain inside the crater. Researchers say they chose Gale Crater for study because there was a sediment deposit there that typically requires water to form.
Read MoreStudy suggests small dams have more negative effects than large dams
A recent study suggests that small dams may have a greater impact on rivers than large dams, as they divert more water away from rivers, according to a press release from the American Geophysical Union. 
 Researchers from Oregon State University studied China’s Nu River, which is home to a variety of dams in the river main stem and its tributaries. In total, 31 small dams were evaluated and compared to four large dams in the main river stem. 
 The research team compared dam impacts to habitat loss, river channel lengths, land affected and landslide risks among 14 total factors. They found small dams had a greater negative impact in nine out of 14 categories. 
Small dams, used to divert water to hydropower stations, had some of the most profound impacts on rivers.

University of Delaware scientists are studying the impacts that rising sea levels might have on marsh ecosystems in the future, the University of Delaware has reported. 
 Scientists predict that rising sea levels could convert marshes into intertidal flats. These conversions could drastically change land composition by stripping sediment from the land, which could alter water quality by exposing substantial quantities of sequestered carbon and pollutants. 
Researchers are monitoring the fluctuations of water flow and sediment concentrations in Delaware’s Brockonbridge Marsh.
