Project B2-1: Effects of Green Infrastructure on Urban Systems

Water sustainability and protection from flood hazards are key challenges in sustaining urban areas in aB2-1 GI example changing world.  One solution that has been offered for both of these challenges is the implementation of a low-impact-development practice called green infrastructure (GI).  Green infrastructure can take the form of small or large detention basins that capture and infiltrate storm water.  GI can also take the form of green roofs, pervious surfaces, and other mechanisms to divert and infiltrate water in urban environments.

Specifically, our team is conducting both observational sciences and modelling to quantify the impact of GI on runoff quantity and quality in urban environments.  We are working with collaborators to then further understand how GI can influence flood response in urban environments and determine what level of hazard can be prevented through the use of GI.

These studies involve water quantity and quality observations in select cities to understand the observed impact of GI.  We are monitoring streamflow, nutrient export, and other water contaminants.  Furthermore, we are also continuing the development and implementation of modelling tools to pursue investigations into which strategies of GI implementation would be most effective at meeting societal goals.

The project will result in information that enables better implementation of GI at either local, lot or city-scale.  We have also an emergent citizen science aspect of our project where folks can take pictures of GI and observe how water presence changes over time. While our citizen science program is not yet active, we have some tests being developed for this upcoming spring (2017).

DATA NEEDS

We seek data about the implementation of GI in different cities in the US. Specifically geographic location data combined with what types of systems have been implemented.

 

DATA USE

We will use this data to develop cross city comparisons and modelling applications in the different cities

Kineros2 Model

We are primarily using the Kineros2 model which is used to model upland and channel environments in arid and semi-arid regions.  However, we are extending its application to urban environments in general.  The model can also model sediment, carbon and nitrogen cycling in these environments.

My research interest lies at the intersection of hydrology and biogeochemistry. In particular I am interested in how hydrologic processes play a fundamental role in controlling biogeochemical processes and fluxes at the catchment scale. My research group spans from field investigations designed to understand these controls at a mechanistic and process level to modelling studies focused on forecasting biogeochemical and water quality conditions at the catchment to basin scale. In particular on the modelling side my group works on developing model calibration and uncertainty techniques that can coexist with the both multi-dimensional and yet sparse data that is typically available for water quality modelling at the basin to catchment scale. My work has spanned environments as diverse as desert scrub and alpine ecosystems and from scales of single soil profiles to 10,000 square kilometer catchments.
