COVID Resources. Reliable information about the coronavirus (COVID) is available from the World Health Organization (current situation, international travel).Numerous and frequently-updated resource results are available from this ’s WebJunction has pulled together information and resources to assist library staff as they consider how to handle coronavirus.

The ERHYM-II model was evaluated to determine if it was capable of simulating the water balance for honey mesquite shrub clusters, grass interspaces, and bare soil in south Texas. The simulated water budget was within 2 percent of the measured evapotranspiration for the shrub clusters and grass interspaces.

(5) ERHYM-II MODEL DESCRIPTION where Y is average above-ground biomass production (kg/ha). The RGC is used to indicate seasonal changes in standing live phytomass. The RGC is calculated with a modified Poisson density function (Wight et al., ) as: ERHYM-Il is a climatically-driven water balance model which functions on the plant community.

Williams Subsurface Protection and Remediation Division. All of the grassland systems studied are projected to lose soil carbon, with the greatest losses in the extreme continental grassland systems.

There are large differences in the projected changes in plant production for some regions, while alterations in soil C are relatively similar over a range of climate change projections drawn from various Cited by: Two computer models for predicting water movement, CREAMS and ERHYM-II, were calibrated and sensitivity tested for use in cool, semiarid environments.

The models were used to predict soil moisture, evapotranspiration, and runoff of two watersheds. Initial estimated soil moisture patterns from CREAMS did not fit field data. Adjustment of the snow melt routine in the model and use of field-based Author: John W.

Laundré. Modeling studies and observed data suggest that plant production, species distribution, disturbance regimes, grassland biome boundaries and secondary production (i.e., animal productivity) could be affected by potential changes in climate and by changes in land use practices. There are many studies in which computer models have been used to assess the impact of climate changes on Cited by: 11 Abstract of Thesis Presen ted to the Graduate School of the University of Florida in Partial Fulfillment of the Requirements for the Degree of Master of Science DEVELOPMENT OF A MANAGEMENT FO CUSED DECISION SU PPORT TOOL FOR OKEECHOBEE BASIN BEEF CATTLE AGROECOSYSTEMS By Sudarshan Jagannathan December Chair: Gregory A.
