A rainwater tank (sometimes called a rain barrel in North America in reference to smaller tanks, or a water butt in the UK) is a water tank used to collect and store rain water runoff, typically from rooftops via pipes. A rainwater catchment or collection (also known as rainwater harvesting) system can yield 2358 litres (623 gal) of water from 2.54 cm (1 in) of rain on a 93 m2 (1,000 sq ft) roof. Rainwater tanks are devices for collecting and maintaining harvested rain. Rainwater tanks are installed to make use of rain water for later use, reduce mains water use for economic or environmental reasons, and aid self-sufficiency. Stored water may be used for watering gardens, agriculture, flushing toilets, in washing machines, washing cars, and also for drinking, especially when other water supplies are unavailable, expensive, or of poor quality, and when adequate care is taken that the water is not contaminated and is adequately filtered. Underground rainwater tanks can also be used for retention ...

In statistics, overdispersion is the presence of greater variability (statistical dispersion) in a data set than would be expected based on a given statistical model. A common task in applied statistics is choosing a parametric model to fit a given set of empirical observations. This necessitates an assessment of the fit of the chosen model. It is usually possible to choose the model parameters in such a way that the theoretical population mean of the model is approximately equal to the sample mean. However, especially for simple models with few parameters, theoretical predictions may not match empirical observations for higher moments. When the observed variance is higher than the variance of a theoretical model, overdispersion has occurred. Conversely, underdispersion means that there was less variation in the data than predicted. Overdispersion is a very common feature in applied data analysis because in practice, populations are frequently heterogeneous (non-uniform) contrary to the ...

To characterise atmospheric input of chemical contaminants to urban rainwater tanks, bulk deposition (wet + dry deposition) was collected at sixteen sites in Brisbane, Queensland, Australia on a monthly basis during April 2007-March 2008 (N = 175). Water from rainwater tanks (22 sites, 26 tanks) was also sampled concurrently. The deposition/tank water was analysed for metals, soluble anions and selected samples were additionally analysed for PAHs, pesticides, phenols, organic & inorganic carbon. Flux (mg/m2/d) of total solids mass was found to correlate with average daily rainfall (R2 = 0.49) indicating the dominance of the wet deposition contribution to total solids mass. On average 97% of the total mass of analysed components was accounted for by Cl− (25.0%), Na (22.6%), organic carbon (20.5%), NO3− (10.5%), SO24− (9.8%), inorganic carbon (5.7%), PO34− (1.6%) and NO2− (1.5%). For other minor elements the average flux from highest to lowest was in the order of Fe , Al , Zn , Mn , Sr , ...

For a correctly specified model, the Pearson chi-square statistic and the deviance, divided by their degrees of freedom, should be approximately equal to one. When their values are much larger than one, the assumption of binomial variability might not be valid and the data are said to exhibit overdispersion. Underdispersion, which results in the ratios being less than one, occurs less often in practice. When fitting a model, there are several problems that can cause the goodness-of-fit statistics to exceed their degrees of freedom. Among these are such problems as outliers in the data, using the wrong link function, omitting important terms from the model, and needing to transform some predictors. These problems should be eliminated before proceeding to use the following methods to correct for overdispersion. ...

Our results suggest a consistent tendency for mammalian assemblages to be more phylogenetically overdispersed than expected by chance, and that this tendency is only detectable by pooling many assemblages. This pattern is seen both across the whole phylogeny (NRI/NRI results) and at the tips (NTI/NTI results). Additionally, the three clades analysed do not have significantly different NRI% or NTI values suggesting that this could be a general, rather than a clade-specific mammalian pattern.. The traditional interpretation of phylogenetic overdispersion is that competition among ecologically similar close relatives has led to exclusion of the inferior competitors and hence an assemblage with more distantly related species than expected. This fits with the predictions of earlier non-phylogenetic studies looking at how competition structures mammalian communities and with the results of Houle (1997), who found that primates that were phylogenetically too close did not coexist. However, if traits ...

package, and available in Stata.. If your data are over-dispersed, try NBR, and compare the log-likelihoods (e.g. via AIC/BIC, etc.), and you can also get the statistical significance of the dispersion parameter from the NBR. From what I can tell, there is no disadvantage of using the NBR model relative to the Poisson model - so when I have overdispersion (in my limited experience, this has always been the case!), I simply use NBR and dont think twice. I could be wrong and would welcome others thoughts. One of the downsides to the quasi-poisson is that it doesnt allow you to get likelihood-based stats, like the AIC/BIC. NBR uses MLE so it does.. This is a wonderful reference walking through how these models are used; its an R vignette, but even if you dont use R it should be very useful.. ...

INTRODUCTION. The Department of Water Affairs (DWA) aims to provide all South African citizens with access to basic water and sanitation services by 2014. The provision of potable water to rural communities has been recommended as a priority by the Department for achieving this goal. Rainwater harvesting (RWH) has been earmarked as a short-term intervention to provide water, especially to dispersed settlement areas (DWA, 2009), and in the 2011/12 financial year the DWA installed 8 068 RWH tanks in 8 provinces. Of these tanks, 6 308 were installed to provide access to a water supply and 1 760 tanks were installed for food production (DWA, 2012). However, possible health risks associated with the consumption of harvested rainwater remain one of the major obstacles hampering the large-scale implementation of RWH systems, as microbial and chemical contaminants have previously been detected in rainwater tanks (Spinks et al., 2006; Sazakli et al., 2007; Lee et al., 2010; Ahmed et al., 2012; Huston et ...

A large number of methods for the analysis of the spatial structure of natural phenomena (for example, the clumping or overdispersion of tree stems, the positions of veins of ore in a rock formation, the arrangement of habitat patches in a landscape, and so on) have been developed in a wide range of scientific fields. This paper reviews many of the methods and describes the relationships among them, both mathematically, using the cross-product as a unifying principle, and conceptually, based on the form of a moving window or template used in calculation. The relationships among these methods suggest that while no single method can reveal all the important characteristics of spatial data, the results of different analyses are not expected to be completely independent of each other.. ...

Rapid estimation of national rainwater yield for low and high performance scenarios is derived using Taylors Hyetal Index (THI). Stochastic representations of the modes of failure of rainwater harvesting (RWH) systems is the foundation of THI. THI holds a strong regression to RWH performance for 7,000 variations in the national residential built environment (r2 = 0.96). A small subset of 34 variations is presented in this summary paper. THI is based on inspecting daily rainfall data from the Bureau of Meteorology, which enables rapid and accurate rainwater yield estimation at potentially any location throughout Australia. A review of the Queensland RWH mandate, using THI, has demonstrated many locations can achieve or are close to achieving their water saving targets. The worst performing region is South East Queensland, which is also an area of high population and municipal water demand. This region is also able to significantly exceed their water saving target, when adopting a RWH system ...

Benefits of Rainwater Harvesting: Berkeley averages roughly 20 inches of rain a year. That rainwater currently flows off your roof, into a stormdrain and out to the San Francisco Bay. Harvesting rainwater helps conserve water and can save you money on your water bill. Using rainwater to water your garden helps replenish local aquifers and reduces the amount of stormwater that drains into the Bay. The harvested water is low in sodium, and chloramine and fluoride free. Rainwater Catchment System Requirements: The easiest, most low-tech system is a rain barrel attached to your downspout that has a spigot and hose out to your garden; no water treatment is necessary. Most simple rainwater catchment systems will not require any permits. More complex systems can involve plumbing and electrical work, soil excavation or other structural work. For rainwater collection projects of this scale, consult a professional to review design, construction and safety considerations, and note the following review and ...

When collecting rainwater it is very important to keep the water clean and safe. The first spell of rain carries a relatively larger amount of pollutants from the air and catchments surface. Without a first- flush system this will be washed off the roof and directly into your rainwater tanks causing the water to become dirty and possibly dangerous. The First- Flush Diverter is installed anywhere before the inlet of the water tank and the runoff from the first spell of rain is flushed out by using a first-flush before rainwater entering to the system or storage tank. There are several possible choices to selectively collect clean water for the storage tanks. The most common is the down-pipe flap. With this flap it is possible to direct the first flush of water flow through the down-pipe, while later rainfall is diverted into a storage tank. The filter is used to remove suspended pollutants from rainwater collected over roof. A filter unit is a chamber filled with filtering media such as fiber, ...

Applied to high-resolution Hi-C data in a lymphoblastoid cell line, HiC-DC detects significant interaction

We found no evidence that calf:cow ratios declined with Date as would be expected if calf mortality were occurring during surveys. However, the timing of calf mortality is not well understood and the majority of calves may die before surveys began. Calves are believed to be born between 15 April and 12 June, most commonly between 30 April and 25 May (Fay 1982). Surveys occurred between 12 July and 12 September, so calves must survive between ~1.5 and 4.5 mo to be sampled. Because the calf:cow ratio includes the effects of both birth rate and survival, the calf:cow ratios we estimated are an underestimate of the true birth rate. More samples are required to estimate the calf:cow ratio. at a specified level of precision when the ratio is small or when overdispersion learn more is high (Fig. 5). More samples are needed when the ratio is small because the standard deviation of a binomial variate Palbociclib increases relative to its mean. as the mean value decreases. While the maximum number of cow ...

Likelihood based inference for correlated data involves the evaluation of a marginal likelihood integrating out random effects. In general this integral does not have a closed form. Moreover, its numerical evaluation might create difficulties especially when the dimension of random effects is high. H-likelihood inference has been proposed where the explicit evaluation of the integral is avoided. The approach also allows extensions handling e.g. (1) complex design experiments, (2) REML type of inference beyond the class of a linear model and (3) overdispersion modeling. The h-likelihood approach to multivariate generalized linear mixed models is extended. The h-likelihood computational algorithms is blended with a Newton-Raphson procedure for the estimation of the correlation parameters. This allows that components of the joint model are interlinked via correlated Gaussian random effects. Further, correlated random effects are allowed within each component. This approach can serve as a basis for ...
