SBIR Phase II: Meshless Petrov-Galerkin Geo-Environ Technology For Wide Scale Field Uses

这项小型企业创新研究（SBIR）第二阶段提出开发一种无网格Petrov-Galerkin地质环境技术，用于大规模的现场应用。地下水供应日益受到有机、无机和放射性污染物的威胁，这些污染物是由于处置不当或意外排放而进入环境的。据估计，仅美国政府场地的修复费用就高达数十亿美元。无网格Petrov-Galerkin计算力学和航空航天技术的进步为大型地下水库的稳定精确模拟提供了简便的手段。拟议的无网格地下水模型- petrov Galerkin （MGM-PG）软件包将为高级水文学家以及地下水流域管理人员、供应商和现场水文学家设计。当前的软件进步将被接口，以方便各种应用程序的概念模型开发。MGM-PG的潜在市场包括：(i)地下水水库数量和质量管理；（ii）清理受污染场地；（iii）将丰水年剩余地表水储存于地下，并将其用于延长旱期（ASR项目）；（四）通过快速渗透和抽取项目安全处置处理过的废水（RIX项目）；（五）地表水和地下水的联合使用；（vi）堆填区；（vii）清理受污染的大型联邦设施。提议的技术适用于数千个EPA国家优先清单，以加快污染场地的清理，也适用于联邦机构、州、县、石油设施和化学工业耗资数十亿美元实施的地下水管理项目。在世界范围内，只有4-5个地理环境规范被开发用于各种各样的社会需求。MGM-PG将是一项新的技术进步，将促进新研究生的无网格进步而不是旧方法的培养。

This Small Business Innovative Research (SBIR) Phase II proposes to develop a Meshless Petrov-Galerkin Geo-Environ Technology For Wide Scale Field Uses. Groundwater supplies are increasingly threatened by organic, inorganic, and radioactive contaminants that are introduced to the environment by improper disposal or accidental releases. Estimates of remediation costs at U.S. government sites alone totals into the billions of dollars. Computational mechanics and aerospace advances in meshless Petrov-Galerkin provide easy means for stable accurate simulations of large groundwater reservoirs without grid generation. The proposed software package Meshless Groundwater Model-Petrov Galerkin (MGM-PG) will be designed for advanced hydrologists as well as for groundwater basin managers, purveyors, and field hydrologists. Current software advancements will be interfaced for easy conceptual model development for various applications.MGM-PG potential market includes: (i) groundwater reservoir quantity and quality management; (ii) cleanup of contaminated sites; (iii) storage of wet year surplus surface water underground and its uses for extended draught periods (ASR projects); (iv) safe disposal of treated effluents by rapid infiltration and extraction projects (RIX projects); (v) conjunctive uses of surface and subsurface water; (vi) landfill sites; and (vii) cleanup of large contaminated Federal Facilities. Proposed technology has applicability to thousands of EPA National Priority List for expedited clean up of contaminated sites and also for groundwater management projects that are implemented at a cost of billions of dollars by federal agencies, State, counties, petroleum facilities, and chemical industries. Worldwide only 4-5 geo-environ codes have been developed for wide variety of societal needs. MGM-PG will be a new technological advancement and will promote training of new graduate students in meshless advances rather than old methods.
