Mathematical Simulation Tools for Developing Dissolved Oxygen TMDLs.

Vellidis, G.; Barnes, P.; Bosch, D.D.; Cathey, A.M. - 2006

established DO standards. Regulators and other professionals are increasingly relying on mathematical simulation models to develop … application. The goal of this article is to provide a guide to mathematical simulation models available for developing DO TMDLs …. Four commonly used DO simulation models (QUAL2E, HSPF, EFDC, and WASP) are described in detail, while the characteristics …

Uncertainty in TMDL Models.

Shirmohammadi, A.; Chaubey, I.; Harmel, R.D.; Bosch, D.D.; … - 2006

Although the U.S. Congress established the Total Maximum Daily Load (TMDL) program in the original Clean Water Act of 1972, Section 303(d), it did not receive attention until the 1990s. Currently, two methods are available for tracking pollution in the environment and assessing the effectiveness...

Historical disturbance regimes as a reference for forest policy in a multiowner province: a simulation experiment.

Thompson, J.R.; Johnson, K.N.; Lennette, M.; Spies, T.A.; … - 2006

Using a landscape simulation model, we examined ecological and economic implications of forest policies designed to emulate the historical fire regime across the 2 x 10⁶ ha Oregon Coast Range. Simulated policies included two variants of the current policy and three policies reflecting aspects...

The Non- and Semiparametric Analysis of MS Models : Some Applications

Melenberg, Bertrand; Li, Y.; Donkers, A.C.D. - Tilburg University, Center for Economic Research - 2006

This paper illustrates how to compare different microscopic simulation (MS) models and how to compare a MS model with real data in case the parameters of interest are estimated non- or semiparametrically.As examples we investigate the marginal single-period probability density function of stock...

Time to burn: Modeling wildland arson as an autoregressive crime function.

Prestemon, J.P.; Butry, D.T. - 2005

Six Poisson autoregressive models of order p [PAR(p)] of daily wildland arson ignition counts are estimated for five locations in Florida (1994-2001). In addition, a fixed effects time-series Poisson model of annual arson counts is estimated for all Florida counties (1995-2001). PAR(p) model...
