I am helping conduct an EPA Wetland Program Development Grant's study that is monitoring the impacts of urbanization on the microclimates and vegetation dynamics within the riparian areas of ephemeral streams.


The Walnut Gulch Experimental Watershed

Synopsis: 
At the Walnut Gulch Experimental Watershed researchers consider the effects of land use change on hydrological processes.
The Walnut Gulch Experimental Watershed surrounds the historic city of Tombstone in southern Arizona. The USDA - Agricultural Research Service established the watershed in the 1950s to study floods and the impact of soil and water conservation projects on runoff.

Trade-offs in Stormwater Recharge

Short Description: 
In Watershed Resources, a new project looks at the potential trade-offs in recharging our groundwater with stormwater runoff.

During Tucson's dramatic monsoons our streets are scoured by stormwater. The water drains down storm sewers, gullies and washes, and eventually to areas that could be used for recharge. Should the city actively recharge our depleted groundwater with storm runoff? Through the project ‘Tradeoffs of Enhanced Urban Runoff-Recharge and Water Quality', SNR Assistant Professor Kathleen Lohse is finding out if pollutants, metals, pathogens and nutrients in storm runoff present a challenge to stormwater recharge.
