A survey of numerous field studies shows that nitrogen and phosphorous export coefficients are significantly d@erent across forest, agriculture, and urban land-cover types. We used simulah’ons to estimate the land-cover composition at which there was a sigt$cant risk of nutrient loads representative of watersheds without forest cover. The results suggest that at between 20 percent and 30 percen...

Abstract. We address, in this chapter, the identification of typical patterns that best characterize a set of sequences. More specifically, we focus on data-driven methods that search for the typical patterns among the observed sequences. In life course studies, such typical sequences serve, for instance, to describe ideal-type life trajectories; i.e., the common way(s) of organizing our life. ...

This paper is concerned with the summarization of a set of categorical sequence data. More specifically, the problem studied is the determination of the smallest possible number of representative sequences that ensure a given coverage of the whole set, i.e. that have together a given percentage of sequences in their neighborhood. The goal is to yield a representative set that exhibits the key f...

Monthly discharge is one of the most important factors considered in designs and hydrological works. Some watersheds are not equipped with needed hydrometric equipment. In such a case average monthly discharge could be estimated from regional monthly water balance models of representative watersheds. In this study, Thornthwaite & Mather (TM) model were used in the Pishkouh watershed in arid cli...

Urban development alters stormflow characteristics and is associated with increasing flood risks. The long-term evaluation of that exacerbate floods, such as peak time-to-peak at varying levels urbanization across different hydroclimates, limited. This study investigated the (1980s to 2010s) effects on key using observed 15 min streamflow data six broad hydroclimate representative urban watersh...
