Educating the compassionate water engineer–a remedy to avoid future water management failures? / Former des spécialistes de l’eau citoyens–une solution pour éviter de futurs échecs en gestion de l’eau?

Abstract

Abstract The number of local and regional-scale water management failures appears steadily to increase despite an apparently higher level of engineering solutions at hand. The objective of this paper is to examine the challenges the existing education system needs to meet in order to produce water engineers capable of responding to the complexity of contemporary and future water problems in relation to societal needs. The next generation of water engineers may stay in their professional functions until 2040 or 2050. It is likely that in this period more critical water management and environmental problems will be experienced than have been encountered so far. The question then arises whether the present water engineers have the proper background education to understand environmental, hydrological, ecological and socio-economic problems to resolve related water management problems. Future water engineers must, to a greater extent, include socio-economic consequences in planned and/or designed water management systems and convey greater transparency regarding risks and societal effects.

测绘卓越工程师培养模式下测绘工程专业课程设置研究

测绘卓越工程师的培养是高校应对当前社会用人企业的人才需求而提出的一种新的概念,而课程设置的科学性是高等院校培养卓越工程师的一个重要环节。本文以本校的测绘专业为例,提出了课程内容设置依据以及新的课程实施方式,并对其进行了详细研究。     

白刺不同果实性状的遗传力估计及优良亲本选择

亲子回归法研究白刺果实不同性状遗传力的结果表明,果径、果形、果色、果味、核形和果实出肉率等性状指标的遗传力较高,说明这些性状变异的遗传贡献较大,可作为白刺果实类型划分的主要指标,其中果径、果味和出肉率可作为白刺果实品质评价和优良亲本选择的主要依据。以果径和出肉率为指标,用家系选择法选择优良亲本可获得较大的遗传增益,且两指标选择的亲本一致,选择效果满意。     

行业高校测绘卓越工程师多元化培养模式构建研究与实践

“测绘卓越工程师教育培养计划”是《国家中长期教育改革和发展规划纲要》高等教育改革和发展中具有战略性意义的一项重要任务。本文紧抓人才培养模式创新的关键性要素作为切入点,创建了一套行业需求为导向的测绘工程专业卓越人才培养体系,搭建“高工程素质、强实践能力”的人才培养模式,完善专业课程体系,加强师资队伍建设,强化多元实践教学,构筑创新实践平台,着力提高学生的工程意识、工程素质和工程实践能力。     

基于工程哲学视角的测绘卓越工程师综合素质的培养

工程哲学是对工程的反思和工程造物的思辨,从而对工程造物的主体——工程师的素质提出了反身诉求。基于工程哲学的视角审视工程师的培养,反思工程教育则具有现实意义。文章结合我国测绘工程师培养现状,以落实"卓越工程师培养计划"作为人才培养的节点,从工程哲学的层面厘清了测绘卓越工程师应具备的综合素质及其培养途径,为工程教育改革和应用型创新人才的培养展现了新思路。     

Ecological periodic tables for benthic macrofaunal usage of estuarine habitats in the US Pacific Northwest

This study shows that spatially and temporally recurring benthic macrofauna-habitat patterns validate the ecological relevance of habitat types to benthic macrofauna and suggest they can serve as elements in ecological periodic tables of benthic macrofaunal usage. We discovered patterns across nine habitat types (intertidal eelgrass [Zostera marina], dwarf eelgrass [Zostera japonica], oyster [Crassostrea gigas] ground culture, burrowing mud shrimp [Upogebia pugettensis], burrowing ghost shrimp [Neotrypaea californiensis], shell, sand, mud, and subtidal) on a variety of benthic macrofaunal community state variables in Grays Harbor, Washington, USA and compared them to those in Willapa Bay, Washington, USA. There were nominal differences in benthic macrofaunal Bray-Curtis similarity between all the habitats investigated except eelgrass and oyster in both estuaries. Across-habitat patterns on mean benthic macrofaunal species richness, abundance, biomass, abundance of deposit, suspension and facultative feeders, a dominance and a diversity index for the five habitats common to both studies were the same on a rank measurement scale: eelgrass ≈ oyster > mud shrimp > ghost shrimp ≈ subtidal. The patterns for most of the habitats and benthic macrofaunal measures were the same on a ratio measurement scale.     

Control of sediment dynamics by vegetation as a key function driving biogeomorphic succession within fluvial corridors

Riparian vegetation responds to hydrogeomorphic disturbances and environmental changes and also controls these changes. Here, we propose that the control of sediment erosion and deposition by riparian vegetation is a key geomorphological and ecological (i.e. biogeomorphic) function within fluvial corridors. In a 3 year study, we investigated the correlations between riparian vegetation and hydrogeomorphic dynamics along a transverse gradient from the main channel to the floodplain of the River Tech, France. Sediment erosion and deposition rates varied significantly along the transverse gradient as a function of the vegetation biovolume intercepting water flow. These effects, combined with the extremely strong mechanical resistance of pioneer woody structures and strong resilience of pioneer labile herbaceous communities, Populus nigra and Salix spp., explain the propensity of biogeomorphic succession (i.e. the synergy between vegetation succession and landform construction) to progress between destructive floods. This geomorphological function newly identified as an ‘ecosystem function’ per se encompasses the coupling of habitat and landform creation, maintenance and change with fundamental ecosystem structural changes in space and in time. Three different biogeomorphic functions, all related to the concept of ecosystem engineering, were identified: (i) the function of pioneer herbaceous communities to retain fine sediment and diaspores in the exposed zones of the active tract near the water resource, facilitating recruitment of further herbaceous and Salicacea species; (ii) the function of woody vegetation to drive the construction of forested islands and floodplains; and (iii) the function of stabilised riparian forests to act as ‘diversity reservoirs’ which can support regeneration after destructive floods. Overall, this study based on empirical data points to the fundamental importance of sediment flow control by pioneer riparian vegetation in defining fluvial ecosystem and landform organisation in time and in space.
