Integrated coastal water monitoring

Geographical Information Systems (GIS) are important took for environmental monitoring and management. However, their limitations in dealing with complex, dynamic, and mission‐critical situations call for alternative approaches. Integrating GIS with dynamic simulation models offers one such solution. Numerical models that simulate physical, chemical, and biological processes greatly increase our understanding of the environment. Many of these models use refined forecast information to accurately predict processes that help in monitoring and managing the environment. Integrating these models with GIS offers new functionalities. The present research couples the MIKE21 comprehensive modeling system for two‐dimensional free surface flows with the spatial analysis strengths of the ArcView GIS. The southern coastal water system of Singapore serves as the study area. The aim is to develop a comprehensive software system that provides support for both environmental managers and land‐use planners in making their decisions.

Can Coastal Management Programs Protect and Promote Water-Dependent Uses?

Anecdotal evidence indicates that commercial and recreational water-dependent uses have been under development pressure in recent years, and in some cases have been converted to other uses. The conversion of water-dependent uses, which range from commercial shipyards to recreational marinas, may have many public costs, including the loss of access to public trust waters, the loss of jobs and associated economic activity, and the loss of traditional working waterfronts. This two-part study investigated the role of five coastal management programs in the northeastern United States in managing, monitoring, and protecting water-dependent uses. First, coastal managers in Massachusetts, Rhode Island, Connecticut, New York and New Jersey were interviewed to assess the conversion problem. Second, in collaboration with New York City-based Regional Plan Association, follow-up interviews were conducted with coastal managers and local planners in Connecticut, New York, and New Jersey to gain greater insight into the role of coastal management programs and local governments in managing and promoting water-dependent uses. This article presents select findings from this study and discusses recommendations for improving the capacity of coastal management programs and local governments to manage water-dependent uses for the benefit of the public.

Management of coastal eutrophication: Integration of field data, ecosystem-scale simulations and screening models

A hybrid approach for eutrophication assessment in estuarine and coastal ecosystems is presented. The ASSETS screening model (http://www.eutro.org) classifies eutrophication status into five classes: High (better), Good, Moderate, Poor and Bad (worse). This model was applied to a dataset from a shallow coastal barrier island system in southwest Europe (Ria Formosa), with a resulting score of Good. A detailed dynamic model was developed for this ecosystem, and the outputs were used to drive the screening model. Four scenarios were run on the research model: pristine, standard (simulates present loading), half and double the current nutrient loading. The Ria Formosa has a short water residence time and eutrophication symptoms are not apparent in the water column. However, benthic symptoms are expressed as excessive macroalgal growth and strong dissolved oxygen fluctuations in the tide pools. The standard simulation results showed an ASSETS grade identical to the field data application. The application of the screening model to the other scenario outputs showed the responsiveness of ASSETS to changes in pressure, state and response, scoring a grade of High under pristine conditions, Good for half the standard scenario and Moderate for double the present loadings. The use of this hybrid approach allows managers to test the outcome of measures against a set of well-defined metrics for the evaluation of state. It additionally provides a way of testing and improving the pressure component of ASSETS. Sensitivity analysis revealed that sub-sampling the output of the research model at a monthly scale, typical for the acquisition of field data, may significantly affect the outcome of the screening model, by overlooking extreme events such as occasional night-time anoxia in tide pools.     

铁路项目甲供物资清算实践与建议

为有效控制工程投资，目前我国铁路在建项目大多采用由铁道部组织建设单位采购，或由建设单位直接招标采购供应主要建设物资的管理模式。如何在项目实施过程中清算甲供物资费用，对确保项目的顺利进行和维护建设单位与施工单位的权益具有重要的意义。此文提出甲供物资清算模式存在的主要制度和操作问题，并据此提出解决问题的建议。     

ISO9001质量管理体系理论在工程监理中的管理应用

研究目的：ISO9001质量管理体系是国际上公认的、科学的、最先进的质量管理方法，监理企业如何正确理解和掌握ISO9001质量管理体系理论内涵及其在工程中的管理应用对企业的发展至关重要，因此有必要对ISO9001质量管理体系的八项管理原则、闭环式管理进行深入的阐述。研究结论：通过论述，得出监理企业应该正确贯彻ISO9001质量管理体系，使企业全员深刻理解ISO9001质量管理体系理论基础“八项管理原则”的内涵，提高贯彻国际标准的自觉性；实施P、D、C、A循环闭环式管理，强化管理过程控制，避免管理流于形式；认真进行管理评审，使企业监理服务质量得到提高，经济效益和社会信誉得到提升。
