Water Balance Model for Small-Scale Water Harvesting Systems

Autor: Donald C. Slack, Vicente L. Lopes, Ignacio Sánchez-Cohen, M. M. Fogel

Publikováno v: Journal of Irrigation and Drainage Engineering. 123:123-128

This paper describes a simple, few-parameters simulation model for a water harvesting-strip farming system. The model includes runoff threshold functions for different soil types, and for different initial soil water contents. The evapotranspiration

Isotopic characterization of atmospheric nitrogen inputs as sources of enhanced primary production in coastal Atlantic Ocean waters

Autor: M. L. Fogel, Hans W. Paerl

Publikováno v: Marine Biology. 119:635-645

Current estimates indicate that atmospheric nitrogen deposition is responsible for 26 to over 70% of “new” nitrogen (N) input to North Carolina estuaries and coastal waters. Concentrations of N in coastal rainfall events in a 2-yr period (August
