The surface features and soil pattern of the Hamilton basin [PDF]

open access: yes, 1967
The Holocene history of the Hamilton basin and development of the soil pattern are closely related. The basin was partly filled by the large alluvial fan of the Waikato River which partly buried a hilly, ash-covered landscape.

Advantages of regional development—A study on poverty alleviation in contiguous destitute areas

open access: yesInternational Studies of Economics, EarlyView.
Abstract The 2011–2020 period is the final stage of poverty alleviation in China, which emphasizes regional development. Using county‐level panel data from 2006 to 2015, we explore the impact of regional poverty alleviation policy on economic growth of contiguous destitute areas (CDAs) in China.

Double-diffusive convection • Buoyancy-Driven convection • Convection in an inclined porous slot [PDF]

open access: yes, 2013
The quantitative analysis of drainage system is an important aspect of characterization of watersheds. Using watershed as a basic unit in morphometric analysis is the most logical choice because all hydrologic and geomorphic processes occur within the ...

The importance of consensus science to managing phosphorus in the environment: SERA‐17 and the legacy of Andrew Sharpley

open access: yesJournal of Environmental Quality, EarlyView.
Abstract Phosphorus (P) loss from agricultural systems to surface waters, and ultimately, eutrophication, presents a wicked problem requiring transdisciplinary solutions. The mission of SERA‐17 (Southern Extension and Research Advisory Information Exchange Group‐17) has been to address this problem by developing “Innovative Solutions to Minimize ...

Denitrifying bioreactors and dissolved phosphorus: Net source or sink?

open access: yesJournal of Environmental Quality, EarlyView.
Abstract Understanding the world through a lens of phosphorus (P), as Dr. Andrew Sharpley aimed to do, adds a deeper dimension for water quality work in the heavily tile‐drained US Midwest where nitrate is often the nutrient of biggest concern. Denitrifying woodchip bioreactors reduce nitrate pollution in drainage water, but dissolved phosphorus ...
