Assessing Deposit Build-up in Corte Madera Flood Control Channel

The Corte Madera Flood Control Channel was designed to prevent waters from overflowing Corte Madera Creek in a highly populated area of Marin County. Since the channel was last dredged in 1990 approximately 5,400 cubic feet of sediment has accumulated. The accumulation of sediment is of concern because the sediment may reduce the effectiveness of the channel, posing a flooding threat to...

Tsunamis

The 2004 Indian Ocean, 2010 Chilean, and 2011 Tohoku disasters have shown how tsunamis are significant threats to coastal communities. To help U.S. coastal communities prepare for future tsunamis, we’ve completed projects related to population exposure and sensitivity, pedestrian evacuation modeling, and vertical-evacuation decision support.

A recent article of ours in the ...

Chiricahua Mountains - Reduction of Channel Gradients

Drainages in the Chiricahua Mountains are impacted by large rain events that cause gullying effects in the headwaters, overflow at road crossings, flooding of campgrounds, and overwhelming sediment loads at outlets (Chiricahua National Monument). Monsoon rains following recent fires cause severe flooding in most drainages and...

Aridland Water Harvesting Study

Most of western North America has been severely grazed by cattle, causing grasslands to deteriorate and desert scrub expansion. Climate in arid and semi-arid regions is often typified by short, intense rainfall events which contribute to short-term flooding and erosion. Associated arroyo cutting occurs when ephemeral creek beds are carved into the floodplain when erratic overland flow occurs;...

Remote Sensing Coastal Change

We use remote-sensing technologies—such as aerial photography, satellite imagery, and lidar (laser-based surveying)—to measure coastal change along U.S. shorelines.

Madeira Beach Video Remote Sensing

Video observations of the coast are used to monitor a range of coastal processes, for example changes in the shoreline position, both seasonally and due to long-term effects such as sea-level rise, and instances of beach and dune erosion during extreme storm events. Research is part of the ...

Ecology of Infectious Diseases

The public is most familiar with parasites' role in spreading infectious diseases to people and domestic animals. In tropical developing countries, malaria, schistosomiasis, and other infectious diseases cause significant human suffering. While most related studies focus on treating patients, Dr. Kevin Lafferty is studying how ecology of the local environment affects transmission of infectious...
