Inverse flood risk modelling under changing climatic conditions
One of the most significant anticipated consequences of global climate change is the increased frequency of hydrologic extremes. Predictions of climate change impacts on the regime of hydrologic extremes have traditionally been conducted using a top-down approach. The top-down approach involves a high degree of uncertainty associated with global circulation model (GCM) outputs and the choice of d ... read more >>

The Next Step in California's Central Valley Flood Management: Connecting Costs and Benefits
Historically, large expanses of California's low-lying Central Valley flooded nearly every winter. Over the past 150 years, individuals, communities, and state and national agencies have increasingly altered the landscape with levees, reservoirs, and bypasses to support agriculture and urban centers. The Central Valley's flood protection infrastructure and the institutions that manage flood risks ... read more >>
System for Treating Flue Gas Desulfurisation Scrubber Wastewater
Scrubbers are used in U.S. power plants to meet emissions standards set by the U.S. Environmental Protection Agency (EPA). Flue gas systems frequently use limestone-forced-oxidation (LSFO) scrubbers to convert SO2 in the flue gas to gypsum, which can be sold for wallboard manufacturing, cement additive, or agricultural applications, thus turning a waste stream into a usable resource.
The prope
