Unlike large boom pumps, which are self-propelled and require special transport permits, a trailer-mounted model can be easily hitched to a truck or other towing vehicle. ...
The State of Nevada faced pressures to meet an increasing number of regulatory requirements while their state continued to grow and develop. Several years ago, they saw value in centralizing and automating and decided to implement i-step. While the system helped with the centralizing and automation, it soon failed to keep up with the demands of the team as they enriched their strategies and ...

We are partners more than just equipment vendors as we work with clients for months before anything is put in the water, helping them with business planning, spatial modeling, permit acquisition and all the other aspects of starting a fish farm. ...
The study is intended to determine whether the United Nations Recommendations on the Transport of Dangerous Goods -- Model Regulations (Model Regulations) definition of aerosols maintains an equivalent level of safety to the definition in the HMR and to assess the risk associated with aligning the definitions. ...
The Euler-Lagrange approach was chosen to model the flow and sediment transport. The numerical model developed relies on the open source library OpenFOAM®, enhanced with new particle/wall interaction conditions to limit sediment deposition in zones with favourable hydrodynamic conditions (shear stress, turbulent kinetic energy). In particular, a new relation is ...
As it’s been over a year since my last air quality modeling-related 4TR article, I thought it appropriate to provide a general status report on the air quality modeling updates that have occurred over the last year. ...
A hydraulic model was developed in order to evaluate the potential energy recovery from the use of centrifugal pumps as turbines (PATs) in a water distribution network characterized by the presence of private tanks. The model integrates the Global Gradient Algorithm (GGA), with a pressure-driven model that permits a more ...
The TSRI is now evaluating the policy landscape and undertaking focused research activities to better understand issues related to grid connection of distributed electric generation, solar PV business models, and permitting processes. Issues raised in the 10 Questions framework catalyzed this research agenda. ...
LimnoTech’s expertise in sewer system and river modeling helped WASA make decisions about two complex programs: combined sewer overflow (CSO) control to improve local water quality, and nitrogen removal to help restore Chesapeake Bay. Problem To meet the Chesapeake Bay Program’s nutrient reduction goals, EPA Region 3 added strict nitrogen limits to the NPDES ...
If so, be aware that any stacks historically constructed at specific heights for the purpose of showing model-predicted compliance with air quality standards, a common practice tied to the process of obtaining a construction permit, may present a problem in future modeling analyses. ...
If these emissions exceed pollutant-specific thresholds, then air dispersion modeling may be required. Offshore Models There are several dispersion models available for modeling sources over water, including CALPUFF and OCD (Offshore and Coastal Dispersion Model). ...
The calibration of hydraulic models of water distribution networks (WDN) is of preeminent importance for their analysis and management. ...
Starting immediately, new major emission sources that apply for air construction permits must demonstrate compliance with the new standards using air dispersion modeling techniques that have not previously been used. ...
Compliance must be demonstrated by performing an air quality dispersion modeling analysis. Based on guidance provided by EPA, some states are requiring NO2 modeling analyses for all permit applications involving NO2 emissions, even for projects that previously might have been exempt from modeling requirements. ...

The huge number of species and reactions involved in the degradation of organic compounds does not permit explicit treatment in regional models, the use of condensed mechanisms is necessary. ...
To assist student understanding of heat transfer through woody stems, we developed an instructional package that included an Excel-based, one-dimensional simulation model and a companion instructional worksheet. Guiding undergraduate botany students to applying principles of thermodynamics to plants in nature is fraught with two main obstacles: (1) students have a limited ...
