Dr Jason Julian an Associate Professor at Texas State University is a Fulbright Scholar who has already visited NZ in 2012 and is back here for the month of May. His background is in Geography, specialising in hydrology.

Dr Julian's studied the influence of catchment characteristics and land use change on optical water quality in New Zealand rivers.

Optical water quality (OWQ), or water clarity, is one of New Zealand's most valuable natural resources, as it influences numerous ecosystem processes and is a key component of aesthetics, recreation, and management of water resources. Given its relevance to so many environmental and socioeconomic values, NZ has placed great importance on maintaining its high level of OWQ. However, OWQ has been degraded in many waters across NZ as a result of land use change, most notably agricultural intensification/expansion. This project will use a unique OWQ dataset along with newly available geospatial data to investigate how land use change and other landscape characteristics affect OWQ patterns in NZ.

As a result of the project he says: "We have found some interesting results so far related to land disturbances associate with drought and grazing patterns, and connections with water quality."
