Drought conditions continued to increase across the United States. Over this past week, DSCI (drought severity and coverage index) increased from 41 to 48 – the highest it has been since mid-February of this year. The percent area of D0 (abnormally dry), D1 (moderate drought), D2 (severe drought), and extreme drought (D3) expanded across the U.S. A weakened Hurricane Dorian tracked northeastward along the Atlantic Coast, inducing rainfall that accumulated in some coastal locations,...

As dam owners across the country have learned in dramatic fashion, disasters usually happen quickly though the conditions that cause them typically build up over time.

Whether your emergency results from a hurricane, a spillway collapse or vandalism, you as a dam owner/manager can be ready with a well-developed, up-to-date and practiced Emergency Action Plan.

Our guidance for knowing what to consider, how to prepare and how to respond recently was featured...

Desalination remains a practical and affordable solution for water supply. Next in our Sustainable Water Management Series, representatives from the Texas Water Development Board, City of Corpus Christi and Freese and Nichols weigh in on the successes of desalination so far in Texas. They’ll also cover the scientific and policy lessons learned so far.

Texas Brackish Groundwater Science and Policy: Texas Water Development Board’s Innovative Water Technologies group was formed to educate the...

Overall, oceanic and atmospheric conditions were consistent with a transition to ENSO (El Niño/Southern Oscillation)-neutral. The August 2019 Climate Prediction Center update indicated that El Niño has transitioned to ENSO-neutral, which is most likely to continue through the upcoming 2019-2020 winter in the Northern Hemisphere (50-55% chance).

According to the National Oceanic and Atmospheric Administration (NOAA) U.S. Seasonal Drought Outlook update covering August through November, existing drought...

In high-rate activated sludge (HRAS) systems, extracellular adsorption and intracellular storage have been referred to as the dominant mechanisms for capturing organic carbon from wastewater.

However, the quantification of storage products under short sludge retention time (SRT) of HRAS systems has rarely been studied until now. Since the measurement of storage products is complex and dependent on several variables, alternative solutions for substrate removal through storage are required to understand the high-rate...
