Regenerative Energie
The exponential model is the simplest and commonest model for landfill waste flushing. It has had a long use, often alongside more complex semi-empirical and physically-based models (Demetracopoulos et al., 1986; Gönüllü, 1994; Lu et al., 1981; Reitzel et al., 1992; Robinson et al., 2004; Straub and Lynch, 1982). Although there has been a rapid introduction of new transport models for wastes, the exponential remains the primary model for landfill ‘source term’ flushing (for example in LandSim, Drury et al, 2003). It is therefore timely to assess how this model relates to other conceptualizations, with particular regard to ensuring it makes accurate (or, at least, slightly conservative) predictions.
As landfill science moves progressively towards understanding the physical mechanisms within the landfill system ‘black-box’ there is an increasing need to relate tried and tested empirical approaches with recent developments. In this paper we consider the physics of conservative solute flushing in relation to exponential representations. This paper identifies three key approaches to the exponential model, identifies certain datasets in which there are difficulties with the model and finds that the issue of scale may remain a continual problem in making reliable long-term flushing predictions.

Die innerstaatliche Umsetzung des Pariser Klimaschutzübereinkommens

Like all public international law treaties, the Paris Climate Accords rely on national law for their implementation. The success of the agreement therefore depends, to a large extent, on the stepstaken or not taken by national governments and legislators as well as on the instruments and mechanisms chosen for this task. Against this background, the present article compares different approaches to the implementation of the Paris Agreement, using court decisions as a means to assess their (legal) effectiveness.
