Available in PDF, EPUB and Kindle. Book excerpt: This report describes a computer program entitled 'Simulation for Harvesting of Aquatic Plants (SHAP), ' and provides instructions and guidelines in planning for mechanical harvesting of plant-infested areas. The model provides a stochastic simulation that evaluates the harvesting system. SHAP utilizes linear programming theory for network flow analysis and queuing theory and is designed for using minimal input data in a conversational manner; that is, the user interacts directly with the program and receives output immediately. The model has been verified using field data collection records. The terrain subroutine organizes irregularly shaped plant-infested areas to be harvested into a distance-flow network (grid). The harvesting subroutine directs the harvesting procedure., The harvester (Aqua- Trio Equipment Co.) mows the aquatic plants; the transporter loads the plants and takes them to the conveyor located on the shoreline. The plants are then transferred from the transporter, via the conveyor, onto a dump truck for disposal at a convenient location. When the mowing, transporting, and disposal operations area complete, the statistics of time and queing operations for each component are computed. Operational costs are complied for each component (default 1977 dollars), including labor, supplies, and power costs required by the harvesting system. No prior experience with computer programming is required since all commands necessary to use SHAP are presented in this report. (Author).

This book was released on 1983 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: To determine the operational time required to mechanically control nuisance-level growth of aquatic plants in Buffalo Lake, Wisconsin, a computer model (HARVEST) was used which simulates all important steps in a mechanical control operation. Model inputs include plant density, distance to nearest disposal site, and mechanical and performance specifications for the harvesting system used. Plant densities were determined at two different times during the growing season by conducting a quantitative field sampling program coupled with aerial photography. A treatment area was selected which consisted of boat lanes covering approximately 20 percent of the area in the eastern two thirds of the lake. The Aquamarine H8-650 and H-400 harvester were selected for simulation. Mechanical control operations were simulated in the treatment area for the two summer periods using each harvester working alone and with a single Aquamarine T-650 transport unit. Surface-topped growth of aquatic plants within the harvestable portion of Buffalo Lake during early and late summer periods covered 35 and 50 percent, respectively, of that area. Harvestable density within the treatment area during early and late summer periods averaged 5.9 and 7.9 tons/acre, respectively. Coontail (Ceratophyllum demersum) was the dominant plant species encountered. Predicted control operation times ranged from 215 to 440 hr for the early summer period and 297 to 627 hr for the late summer period. Predicted production rates were greatest for the H8-650 harvester working with a transport unit.

Download or read book Handbook of Environmental and Ecological Modeling written by Sven E. Jorgensen and published by CRC Press. This book was released on 1995-12-13 with total page 698 pages. Available in PDF, EPUB and Kindle. Book excerpt: With descriptions of hundreds of the most important environmental and ecological models, this handbook is a unique and practical reference source. The Handbook of Environmental and Ecological Modeling is ideal for those working in environmental modeling, including regulators and managers who wish to understand the models used to make assessments. Overviews of more than 360 models are easily accessed in this handbook, allowing readers to quickly locate information they need about models available in a given ecosystem. The material in the Handbook of Environmental and Ecological Modeling is logically arranged according to ecosystem. Each of the sixteen chapters of the handbook covers a particular ecosystem, and includes not only the descriptions of the models, but also an overview of the state-of-the-art in modeling for that particular ecosystem. A summary of the spectrum of available models is also provided in each chapter. The extensive table of contents and the easy-to-use index put materials immediately at your fingertips.
