Fourteenth Annual Report for the year ended 31st March, 1965

This is the fourteenth Annual report of the Cumberland River Board on information of its activities and responsibilities on river management in its area between the beginning of April 1964, to the end of March 1965. The report contains 5 main sections on water resources, land drainage, fisheries, pollution, and finally the expenditure and income for the 12 month period. The first area that the report deals with is water resources, which includes information on the completion of gauging stations, abstraction of water and rainfall and river flow. The section on land drainage looks at work on improvement schemes, floods and information on maintenance work carried out on rivers including Wampool, Waver, Wiza, Ellen, Cocker, Keekle, Marron, Ehen, Bleng, Esk, Mite, Caldew and Petteril. The fisheries section covers 5 districts of the River Eden, Esk, Derwent, Ellen and South West Cumberland. It includes angling information and a general report for salmon and sea trout, brown trout and freshwater fish. Fish disease and fish hatchery are also covered as well as Byelaws and fisheries protection. The fourth section on pollution deals with water quality and information on sewage and trade effluents. The River Boards preceded the Environment Agency which came into existence in 1996.

Avaliação de condicionadores em solo para uso em telhados verdes com vistas à retenção hídrica.

As inundações são fenômenos naturais que ocorrem devido às chuvas de grande magnitude, agravadas nas áreas urbanas pela impermeabilização do solo e ineficiência dos sistemas de drenagem. Os telhados verdes surgem como uma medida compensatória estrutural que pode reter parte da água precipitada, adiando o pico de escoamento. O objetivo deste trabalho foi de desenvolver uma combinação de solo e condicionadores para telhado verde, promovam um aumento relevante na capacidade de retenção hídrica e um maior adiamento do pico de escoamento das águas pluviais. Este estudo foi dividido em duas etapas. Na Etapa 1, foram analisadas, em colunas de percolação, três condicionadores nas seguintes concentrações: Gel retentor Stockosorb (2; 4; 6 g/dm3), Fertilizante de liberação lenta Osmocote (4,7; 7,1; 9,0 g/dm3) e Zeólita (30; 50; 70 g/dm3), em três eventos (regas) consecutivos de chuva simulada na intensidade de 57 mm/h. A avaliação das concentrações mais adequadas dentre as testadas para cada condicionante foi baseada nas análises referentes à retenção hídrica (altura do meio após a rega; tempo de adiamento do escoamento; mm retidos; intensidade da água percolada em mm/min) e à qualidade da água percolada (pH, oxigênio dissolvido, turbidez e sólidos). Na Etapa 2, foi avaliada, em vasos, a influência da presença de três espécies de plantas (Arachis pintoi; Raphanus sativus; Lavandula angustifolia) em dois tipos de meio: solo sem condicionadores; solo com condicionadores nas melhores concentrações indicadas na Etapa 1, sendo simulada apenas um evento de chuva de 57 mm/h. Foram analisados parâmetros biológicos (germinação; plantas sobreviventes; comprimento do caule e da raiz; pesos da biomassa do caule e da raiz); retenção hídrica (altura do meio após a rega; tempo de adiamento do escoamento; mm retidos; intensidade da água percolada em mm/min); qualidade da água percolada (pH; oxigênio dissolvido; turbidez; sólidos; nitrato; amônia; fósforo total). Os resultados da Etapa 1 indicaram que o gel promoveu de forma significativa um aumento na retenção hídrica, e adiou o início da percolação de água, além de promover ligeira elevação do pH na água percolada. A adição de zeólita resultou em um aumento significativo da retenção hídrica, porém tal aumento não é vantajoso visto que este representa um custo adicional que poderia ser reduzido com o aumento da proporção do gel na coluna. A adição de fertilizantes não promoveu mudanças na qualidade da água percolada. Na Etapa 2, somente o efeito da presença de A. pintoi (maior produção de biomassa de raiz e caule) e R. sativus foram avaliadas. A presença dos condicionantes no solo proporcionou um desempenho significativamente superior em relação a retenção hídrica (altura do substrato e adiamento do pico de chuva) e qualidade da água percolada (pH e turbidez) quando comparados aos testes realizados na presença somente de solo. O fertilizante influenciou nas altas concentrações dos nutrientes (nitrogênio e fósforo) na água percolado nos resultados. A presença do gel no substrato, resultou numa capacidade superior de retenção de hídrica, e consequentemente no adiamento do pico de intensidade de chuva. Sendo assim, recomenda-se a aplicação do gel em telhados verdes para futuros estudos em ambientes externos.

Report on proposed improvements to Teignmouth Harbour

This is the Report on Proposed Improvements to Teignmouth Harbour from 15th March, 1971 prepared for the Teignmouth Harbour Commission. It reviews the Scheme III Breakwater along the lines recommended by the Hydraulics Research Station and the implications of deepening the berths at the Eastern Quay to a depth of thirteen feet below chart datum. The layout of the Hydraulics Research Scheme III Breakwater, as described in Para.16 of their Report No. EX489 dated April 1970, is shown on the accompanying Key Plan to a scale of 1:2500. It contains a subsoil survey and boreholes structure. It goes through the permissible draughts of ships and turning area, training wall, deepening of the eastern quay dredging and sewage dispersal.

Proposed Environmental Quality Standards for Nonylphenol in Water

This is the Proposed Environmental Quality Standards (EQS) for Nonylphenol in Water produced by the Environment Agency in 1997. The report reviews the properties and uses of Nonylphenol, its fate, behaviour and reported concentrations in the environment, and critically assesses available data on its toxicity and bioaccumulation. The information is used to derive EQSs for the protection of fresh and saltwater life as well as for water abstracted to potable supply.Nonylphenol (NP) is used extensively in the production of other substances such as non-ionic ethoxylate surfactants. It is through the incomplete anaerobic biodegradation of these surfactants that most nonylphenol reaches the aquatic environment in effluents, e.g. from sewage treatment works and certain manufacturing operations. It was explicitly stated by the Environment Agency that the EQS was to be derived for NP and not Nonylphenol ethoxylates. However, since NP is unlikely to be present in the aquatic environment in the absence of other nonylphenol ethoxylate (NPE) degradation by-products, the toxicity, fate and behaviour of some of these (i.e. nonylphenol mono- and diethoxylates (NP1EO and NP2EO), mono- and di-nonylphenoxy carboxylic acids (NP1EC and NP2EC) have also been considered in this report. In the aquatic environment and during sewage treatment, NPEs are rapidly degraded to NP under aerobic conditions. NP may then be either fully mineralised or may be adsorbed to sediments. Since NP cannot be biodegraded under anaerobic conditions it can accumulate in sediments to high concentrations.

River Ehen and Calder sub catchment Management Plan

This is the River Ehen and Calder sub catchment management plan: Consultation Report September 1993 produced by the National Rivers Authority (NRA) North West Region in 1993. The report focuses on the management plan of both River Catchments Ehen and Calder, in North West England, UK. The Catchment Management Plan (C.M.P.) enabled the NRA to summarise the status of the catchment, identify the main issues and present its vision of the future. It provides a strategic policy framework for its Management and influences decision making leading to improvements in the water environment. The report contains sections on Description of Catchment, Catchment uses by NRA function, Target and objectives of the plan, Summary of Issues and Catchment Issues. The section on description of Catchment includes a general description, Transport, Geology, major services, summary of key details, area, topography, administrative details, main towns and population, water quality Sewage Treatment Works Trade effluent discharges, Water Resources, flood defence and land drainage and Fisheries.

River Irk intensive survey

This is the River Irk intensive survey produced by the North West Water in 1986. This report focuses on the Intensive Survey carried out on the River Irk on 15 April 1986. The river Irk was one of the most polluted rivers in North West Water's area. In dry weather the bulk of the flow in the river originated from the 3 sewage works within the catchment (Castleton ETW, Royton ETW and Oldham ETW). The river Irk was badly affected by numerous unsatisfactory storm sewage overflows (SSOs) within the catchment. Several sewerage projects had been carried out within the Irk catchment especially in the Middleton area, where earlier major redevelopment of the old town centre took place between 1969 and 1976, at which time the main sewers were reconstructed. The survey was designed to investigate the changes in the water quality of the river Irk which take place during wet weather. Because of manpower and analytical restrictions the study on Wince Brook and the river Irk upstream of Wince Brook was limited to their bottom reaches.

The Irwell. Story of an industrial river

This is the Irwell: Story of an industrial river document produced by the North West Water in 1979. This report is a leaflet format document. It focuses on the historical evolution of River Irwell, since it was “born” the river Irwell, about three hundred million years ago when shallow seas covered most of south east Lancashire and Europe to present years. It looks at Irwell’s pollution, highlighting the Irwell’s lower stretches were some of the region was the most polluted due to the population growth and establishment of industrial activities i.e. Lancashire’s great cotton industry, breach and dye works, paper mills, tanneries, chemical and gas works. Wastes from these industries were discharged directly to the river, together with crude sewage from an ever increasing population. However over the years the condition of the Irwell was gradually improved.

Regulação do saneamento básico no Brasil: os objetivos de política e as experiências nos municípios fluminenses

Este texto analisa os impactos da regulação sobre os serviços de saneamento básico no estado do Rio de Janeiro. Trata-se de um estudo geral do setor de saneamento básico desde a criação do Planasa até os dias atuais e da Lei n 11.445/07 que regula o acesso dos serviços de abastecimento de água, esgotamento sanitário, coleta de resíduos sólidos e drenagem de águas pluviais urbanas. No decorrer do trabalho são discutidas as transformações trazidas com a Constituição de 1988 e a Lei dos Consórcios Públicos. Destaca-se no último capítulo a tentativa de determinar uma possível relação entre a regulação e a expansão dos serviços de saneamento no estado do Rio de Janeiro.

River Yealm SAP Consultation

This is the River Yealm Salmon Action Plan Consultation document produced by the Environment Agency in 2003. The report pays attention on the external consultation of the River Yealm Salmon Action Plan (SAP). This strategy represents an entirely new approach to salmon management within the UK and introduces the concept of river-specific salmon spawning targets as a salmon management tool. The River Yealm Salmon Action Plan follows the format of those completed for the rivers Tamar, Lynher, Tavy, Camel, Fowey and Plym. It is the final one of seven action plans that will be produced for salmon rivers managed by Cornwall Area. The River Yealm SAP contains a description of the river catchment and highlights particular features that are relevant to the salmon population and the associated fishery. Notably there are potable water abstractions in the headwaters, workings for china clay on the main tributary, two inert waste landfill sites and an aggregate quarry adjacent to the main river and inputs from several Sewage Treatment Works (STW) and two industrial estates. The main River Yealm has been designated as River Ecosystem Class 1 for its water quality objectives. This is the highest water quality target set for rivers.

Análise socioambiental das sub-bacias do Rio Morto e do Rio Maracanã, Rio de Janeiro, a partir de indicadores ambientais e da percepção da comunidade do entorno.

O presente trabalho aborda duas sub-bacias hidrográficas do município do Rio de Janeiro através da apresentação de indicadores ambientais e da percepção de seus moradores. Destaca-se que a interação/utilização dos recursos no meio urbano em um município de alta densidade demográfica sofre reflexos principalmente do padrão de ocupação do território. As duas sub-bacias aqui analisadas, do rio Morto e do rio Maracanã, representam, respectivamente, bacias periurbanas e urbanas. Como indicadores ambientais são apresentados dados secundários, majoritariamente de órgãos públicos, como IBGE e INEA. A percepção dos moradores é representada pelas respostas a 210 questionários aplicados nas áreas das sub-bacias. Os principais resultados são apresentados ao longo do texto em mapas temáticos. Tanto entre os indicadores, quanto em relação à percepção, os serviços de saneamento demonstraram ter papel fundamental nas condições dos rios. Pequenos trechos mais carentes de cobertura de esgoto nas sub-bacias resultam em deterioração da qualidade da água, embora a cobertura de coleta geral apresente altos percentuais. Um ponto de destaque entre os problemas levantados através dos questionários é a ocorrência de enchentes. Dentre resultados positivos cita-se a cobertura de coleta de lixo, próxima a 100% nas sub-bacias. Uma matriz PEIR (pressão-estado-impacto-resposta) condensou as informações obtidas pelos indicadores e sinalizou os fatores associados. A matriz destacou para a sub-bacia do rio Morto o menor acesso ao abastecimento de água e à rede de esgoto, e para sub-bacia do rio Maracanã a degradação da qualidade da água, representada pelas baixas concentrações de oxigênio. Áreas com mais alta densidade populacional representaram a principal pressão exercida nas sub-bacias.
