Water world : An artificial shape of meaning

Eriksson, Julia January 2015 (has links)
Water World is a water reservoir in the shape of a mountain, with a steel grid body and a shell of shot concrete. It is situated in the national city park Lill-Jansskogen in Stockholm and the emergence of this project is the disrepair of an existing reservoir. Humans, like all things alive, are dependent on water. We survive approximately three days without water. The stored water is the start of civilization, the first of all functions in society we would not cope without in case of collapse. Instead of habitually reshaping nature in accordance with our needs and wishes, this reservoir mimics nature with synthetic means. It questions the idea that we by technical means could create an equilibrium between nature and late capitalist society. Our systems handling water enables modern life. Water World celebrates this function, and life. After construction the man-made surface is exposed to decay and with time the interior structure will stand as a ruin marking the end of the era of globalisation. / Water World är en vattenreservoar inkapslad i ett konstgjort berg, med en stomme av stål och ett yttre av betong. Reservoaren är belägen i Lill-jansskogen i centrala Stockholm, Sveriges enda nationalstadspark. Människan liksom alla levande varelser är beroende av vatten för sin överlevnad. Vi överlever ca tre dagar utan vatten. Det lagrade vattnet är början påcivilisationen, den första av samhällets funktioner vi inte skulle klara oss utan vid en eventuell kollaps. Istället för att vanemässigt forma naturen efter våra behov och önskningar försöker reservoaren efterlikna naturen med syntetiska medel. Den ifrågasätter idén om att vi med teknikens hjälp kan skapa en balans mellan natur och vår senkapitalistiska kultur. De system människan har utvecklat för att lagra vatten möjliggör våra moderna liv. Water World hyllar denna funktion, och livet. När konstruktionen är färdig kommer den av människan formade ytan med tiden förfalla och interiörens struktur lämnas som en ruin att markera slutet av eran av globalisering.

Finanční náklady na retenci vody v krajině a tvorbu mokřadů na území České republiky. / The costs of water retention in landscape and wetland creation in Czech republic.

ČERNÝ, Jan January 2011 (has links)
Different types of man-made retention systems (polder, small water reservoir, large water reservoir) have been characterized by means of their retention potential and cost of retention per one cubic meter. As part of these man-made retention systems, wetland area has been created. Its acreage and build expense has been counted up inreference to total area, which differed within various types of retention systems. The results of these calculations, Hessenian method, and the metohod of agricultural land use were used to evaluate natural river basin and its retention potential. The calculations reveal, that model locality of natural river basin has the lowest value, when used for agriculture cultivation. Hessenian method showed the highest value. The expense of substituting the natural retention of the model locality with different man-made retention systems is estimated to be 0.5?1.6 billion CZK.

Water and pollutant flowsthrough the MejdurechyeReservoir, Uzbekistan

Koutsouris, Alexander January 2008 (has links)
<p>Karakalpakstan, Uzbekistan, has faced water scarcity and low water during several years as a consequence of Uzbekistan’s extensive irrigation of cotton fields. The environmental status of the Mejdurechye Reservoir, which is the largest in the lower Amudarya Delta, is therefore of great local importance. This thesis quantifies pollutant mass flows through the reservoir, concidering for instance salt, DDT and Lindane (HCH). Surface water flow paths through Mejdurechye Reservoir are also conceptualized in order to provide suggestions for future a possible monitoring program.</p><p>Results show that chloride concentrations have decreased during July 2007-2008 with at least 10% in spite of a large specific evaporation and a reservoir volume reduction of at least 60%. The most important implication of this is that pollutants in the reservoir cannot have been subject of evapoconcentration during this period. DDT and Lindane have on the other hand increased with up to 50000% in concentration and 20000% mass compared to measurements dating back to 2002. A rough age estimation of DDT shows that the DDT has been mobilized recently. The results of this thesis may prove valuable when forming environmental policy plans and setting up future monitoring programs.</p>

Vandens telkinių pakrančių temperatūros kaitos režimas / Regime Of Temperature Change On Water Reservoir Riparian

Vaina, Karolis 15 June 2009 (has links)
Kiekvienas vandens telkinys daugiau ar mažiau veikia savo aplinką. Viena iš tokio poveikio formų yra poveikis mikroklimatui, atsirandantis dėl garavimo metu iš vandens. Visoms bendrijoms yra būdingi reiškiniai, suderinti su natūraliai pasikartojančiais procesais. Kiekvienai rūšiai būdingas nuoseklus augimo ir žydėjimo periodas, kurį daugiausia derina ir reguliuoja pagrindiniai aplinkos klimatiniai gradientai. Darbo objektas – Tyrimui pasirinktas objektas – Karkliškės tvenkinys esantis Akademijos miestelyje. Darbo tikslas – Nustatyti vandens telkinio pakrantės temperatūros variacija dirvožemio paviršiuje įvairaus nuolydžio ir orientacijos šlaituose. Darbo metodai. Buvo pasirinkti ir išmatuoti du tvenkinio šlaitai šiaurinis ir pietinis. Šiaurinis šlaitas buvo pasirinktas 25, o pietinis 37 laipsnių nuolydžio. Kiekviename variante buvo atliekami matavimai šešiose vietose. Matavimai buvo vykdomi nuo balandžio mėnesio 12 dienos iki spalio mėnesio 28 dienos, kas 10 dienų. Visi matavimai atlikti 10 valandą ryte. Iš viso atlikta 21 matavimas. Darbo rezultatai – Kontrastas tarp pietinio ir šiaurinio šlaito augalijos rodo, kad Šiauriniame šlaite, kuris yra šaltesnis ir drėgnesnis. Todėl nestebina ir atitinkami temperatūros bei drėgmės skirtumai. Bet jeigu padarę pjūvį nuo vieno šlaito iki kito, tirtume ir toliau pastebėtume labiau nuoseklų, o ne pertraukiamą mikroklimato ir augmenijos gradientą. Daugelis žolinių augalų formuoja žiedynus, žydi arba dera vėlai pavasarį. Tačiau... [toliau žr. visą tekstą] / Each water reservoir more or less influences its surroundings. One of the forms of influence is an effect on microclimate that occurs owing to evaporation. All communities have typical phenomena consentaneous with natural repetitive processes. Every species has characteristic successive periods of vegetation and bloom that are harmonized and adjusted by basic climatic gradients. Subject of research-The Karkliškės pond in Akademija small town has been chosen for the experiment. Aim of research-The purpose of the work is to establish the influence of temperature variation on flora in differently inclined and orientated slopes of a water reservoir. Eethodology-Two pond slopes – northern and southern – have been chosen and measured. The northern slope has incline of 250 and the southern one of 370. The measurements have been fulfilled in six places of each variant. The measurements were carried out from the 12th of April to the 28th of October every 10 days. All measurements were fulfilled at 10 am, altogether 21 measurements. Results of research-The contrast of flora between the southern and the northern slope shows that it is situated out of continuity due to position and orientation. Appropriate differences in temperature and humidity are observed too. However, if we made a section of both slopes we would observe more successive gradient of microclimate and flora. On northern slope, which is cold and wet, most grass form truss, blossom and crop in late spring. On dry and... [to full text]

Entre seus objetivos destaca-se a análise ambiental através da percepção de seus usuários, detectando o nível de informação dos mesmos acerca dos impactos gerados pela ocupação e intervenção antrópica e a caracterização da qualidade da água e seus reflexos na saúde humana, identificando o de interesse dos mesmos em participar de ações para melhorar a qualidade ambiental da área. Para sua realização desenvolveu-se pesquisa bibliográfica da temática, bem como um estudo de campo utilizando os seguintes instrumentos para coleta de dados: Questionário; Associação livre de palavras, Coleta e análise das águas do reservatório superficial Açude Grande. Esta pesquisa revelou que em seu entorno predomina a ocupação por edificações e as poucas áreas claras são desprovidas de mata ciliar e utilizadas para atividade rural (agricultura e criação de animais). Alguns dos entrevistados não apresentam relações afetivas com a área, no que se refere à qualidade ambiental demonstrando desconhecer a importância do reservatório para o ambiente em contrapartida demonstram um apreço por sua função paisagística. Para a caracterização da qualidade da água do açude foi procedida a sua coleta in loco e seqüencialmente a análise físico-química e microbiológica, no período de outubro de 2009 a fevereiro de 2010, respaldando-se na legislação vigente (resolução CONAMA 357/05 e portaria 518/04) onde se constatou que alguns parâmetros encontram-se fora de conformidade para consumo humano. Conclui-se que o açude encontra-se numa área com alto risco de poluição e/ou contaminação devido à crescente urbanização que vem sofrendo, evidenciando a necessidade de intervenções no que concerne a produção de um programa de recuperação da qualidade ambiental da área de seu entorno, que inclui desde a recuperação da mata ciliar até a implantação de programas permanentes de Educação Ambiental, voltada para a busca da consciência ambiental e o exercício de seus direitos como cidadãos. / This study was developed in order to diagnose the environmental impacts in the insertion area of urban surface reservoir Açude Grande in Cajazeiras city / PB and its surroundings. Among its objectives is to highlight environmental analysis through the perception of its users, detecting the level of the same information about the impacts generated by the occupation and anthropic intervention and characterization of water quality and its effects on human health, identifying the interest of them to participate in actions to improve the environmental quality of the area. For its realization was developed a literature search followed by the field study, where worked, using the following instruments for data collection: Questionnaire; free words association, with the terms inducers: Açude Grande, Environment, Collection and analysis of the waters of Açude Grande reservoir surface. This search revealed that around it dominates the occupation of buildings and the few bright areas are devoid of riparian vegetation and used for rural activities (agriculture and animal creation). Some of the interviewed did not have emotional relationships with the area, with regard to environmental quality showing disregard the importance of container to the environment in contrast show an appreciation for your landscape function. To characterize the water quality of the reservoir was performed to collect his loco and sequentially physico-chemical and microbiological, in the period 2009 October to 2010 February, supported in the legislation (CONAMA 357/05 and Decree 518/04) which found that some parameters are out of compliance for human consumption. It is concluded that the dam is in an area with high risk of pollution and / or contamination due to increasing urbanization that has been suffering, highlighting the need for interventions regarding the production of a recovery program of environmental quality in the area of their surroundings, ranging from the recovery of riparian vegetation to the deployment of permanent programs of Environmental Education, rooted in the pursuit of environmental awareness and exercise their rights as citizens.
