A rights-based approach to water allocation and trading would allow water agencies that proactively invest in conservation to receive a larger dry-year allocation, making it possible to store the water they save for their own use or sell the water to other cities during dry years. This system would create incentives for agencies to conserve even in wet years. Working with our client, the Long Beach Water Department, our team investigated the possibility of a market for inter-city water trading in Southern California. While ag→ag and ag→urban water transfers are becoming commonplace, robust urban→urban markets are still rare. The service area of the Metropolitan Water District of Southern California provides an ideal substrate for such a market due to its shared infrastructure, which eliminates the conveyance issue and enables 'paper water' trades. See our website for more information.
We presented our research at AWRA's Spring Conference: Water for Urban Areas: Managing Risks and Building Resiliency (Los Angeles, 2015).
Our team also participated in a panel entitled Market-based Approaches to Water Management at the 2015 California Water Policy conference.
Using statistical techniques like time series analysis, I analyzed the water department's customer data to identify usage patterns that represent different types of leaks. The goal was to create an algorithm that can spot leaks as they occur and identify when customers repair them.

The impact of dam removal on marine-derived nitrogen in tree-rings | Elwha River, Washington
"The ongoing removal of two ~100-year-old dams on the Elwha River in Washington state provides an opportunity to study whether the sequestration of marine nitrogen in tree rings can provide a useful historical record of salmon returns. By measuring δ15N, δ18O, and C:N ratios in increment cores from Sitka spruce, we plan to observe the migration of marine-derived nitrogen through the ecosystem in real-time, shedding light on open questions about the utility of tree rings as a tool for studying salmon returns."
"Imagine a plan to divert water from the Canadian Rockies to the Great Salt Lake in Utah, and you’ll have some idea of what Sanusi Imran Abdullahi is proposing. Abdullahi, the Nigerian-born executive secretary of the Lake Chad Basin Commission, is in charge of saving one of the world’s most endangered water bodies, central Africa’s Lake Chad. Threatened by a perfect storm of climate change, overwithdrawals, and a rapidly growing population that depends on fishing and farming, Lake Chad has shrunk to 1/10th of its size over the last 50 years.
With some scientists predicting the lake will disappear entirely by 2030, Abdullahi is now banking on a dramatic last-ditch effort to rehabilitate the basin: a massive diversion of water from the Congo River watershed, 1000 km away, into the Chari River which feeds the lake. If completed—an increasingly unlikely prospect given violence in the Central African Republic—this would be the largest interbasin water transfer in the world."
