Understanding urban assets : using remote sensing to manage stormwater run-off
… growth is also causing increases in stormwater run-off. High levels of run-off are in turn having adverse effects on these communities environment health, as it is degrading local water quality and damaging stream channels. Development in many of these same communities is causing them to fall …

SOIL PHOSPHORUS AND NITROGEN EXPORT AND RETENTION IN RAINFALL RUN-OFF FROM MANURED LANDSCAPES
Rainfall run-off from manured agricultural fields can be high in nitrogen (N) and phosphorus (P) due to excess nutrient application that is unused by crops. This can pose the risk of eutrophication of nearby surface water bodies receiving run-off. The objective of this study was to determine the …

Characterization of Bacterial Transcriptional Regulatory Networks through Genome-Wide in vitro Run-Off Transcription RNA-Seq (ROSE)
… these approaches, a new method called ROSE (Run-Off transcription/RNA-sequencing) has been developed for characterizing bacterial promoters genome-wide. This method involves in vitro transcription coupled to transcriptome sequencing specific for native 5′-ends of transcripts. This method is …

A study of flash floods on a small drainage area
… of the actual amount of water passing as run-off during the storm, as well as the peak rate of flow. All the available data have been reviewed with the above purpose in mind. The unit graph method has been applied to this investigation as the most logical method of solution. With the data …

Estudo de previsão de cheias em tempo real com modelos empíricos e semi-conceitual
… models were tested: a semi-conceptual rainfall run-off model, and ARIMAX empirical model and a conjugation: a rainfall run-off model for streamflow forecasting and and ARIMAX for error forecasting of the semi-conceptual model. The models were tested with date from Ibirama basin, in the Itajaí …

Influences of forests on invertebrate communities in Icelandic streams
… is composed of solid basaltic rock with direct run-off streams. The streams drain treeless, birch and conifer forested catchments. The bedrock of the southern research area is porous hyaloclastite, and the streams are spring-fed. These streams drain two different types of catchments: barren land …

Imputação de dados em séries temporais: uma proposta de correção para o atraso nas notificações dos casos de COVID-19 por data de início dos sintomas via Modelo Estrutural
… atraso em um arranjo conhecido como triângulo de run-off, no qual as linhas representam as datas de ocorrência dos eventos e as colunas correspondem aos atrasos. Neste trabalho, convenientemente utilizaremos uma reorganização dos dados do triângulo de run-off em um vetor obtido pelo empilhamento …

An integrated modelling approach for sustainable management of semi-arid and arid rangelands
… slope where vegetation cover serves to obstruct run-off and decreases evaporation from the soil. Disturbances like overgrazing influence these positive feedback mechanisms by affecting vegetation cover and composition. In the second part, I present a modeling approach that has the power to …

Hydrochemistry in an Alpine Karst System, Sequoia and Kings Canyon National Parks, California
… The data show a system with a pronounced spring run-off, extended periods of base flow quiescence, storm responses tied to precipitation as rain or as snowfall, and clear diurnal and seasonal patterns of discharge. pH and spC values show an inverse relationship to discharge and temperature, which …

Effects of road salt on photosynthetic and enzyme activity of stream biofilms
<p>Road salt application and salt-laden run-off are common, yet little information exists about its influence on periphyton. I measured extracelluar enzyme activity and photosynthetic activity of natural winter stream periphyton communities under various short-term laboratory salt exposures. The …

Investigation of closure techniques for the Rusal Aughinish Bauxite Residue Disposal Area (B.R.D.A.) and the impact on the surrounding environment post-closure
… in 2006. Space to store residue was estimated to run out in 2011, thus requiring the construction of the extra 80 hectares which needed planning permission and an extension of the licence. It was vital to get planning permission and licence extension. There is a large volume of residual …

Smart Wall Outlet Design and Implementation for the DC House Project
… everyday AC appliances are designed to operate off of 120V coming from the wall outlet in our homes. This voltage is a standard set from our established infrastructure. Unlike AC devices, DC devices do not have any set standard of voltage they all will run off of. This presents a problem for the …
