... Caribbean (SWC) experiences stable temperatures without significant upwelling (27–31 °C; Kaufmann and Thompson, 2005 ), resulting in very low levels of planktonic nutrients. In contrast, nutrient contents during the rainy season increase four-fold, fed by terrestrial runoff, leading to a peak in planktonic...

..., we used a debris-flow inventory from this period of dry and wet extremes to examine the processes and climatic controls underlying the regionwide debris-flow response. Results reveal shallow landslides and surface runoff as two distinct initiation mechanisms, linked to different geologic settings...

... ). These alterations induce greater runoff and flooding potential ( Ebel et al., 2012 ). The extent of impacts often increases with the severity of burn ( Doerr et al., 2006 ; Moody et al., 2008 ; Ryan et al., 2011 ) and rainfall intensity ( Moody and Martin, 2001a ; Moody et al., 2013 ). Dry-season flow can remain...

...I. Chenini; L. Kouzana; M. H. Msaddek ABSTRACT Urbanization modifies the natural water cycle. In this study, a weighted-rating multicriteria analysis was adopted to quantify the runoff index and to assess the impact of urbanization on the water cycle. The considered parameters are (1) slope, (2...

..., facies and architectural analyses shed light on the original morphodynamics and on factors of bedrock inheritance. Our results substantially underline how fine-grained, runoff-dominated deposits can be linked with alluvial fan systems if a clear geomorphological context is available. Supportive field...

... Snow and ice are important parameters which control the Earth’s energy balance. Meltwater from snow and ice play a significant role in river discharge. A large source of runoff and groundwater recharge in mountainous areas is melting snow and ice at higher and middle elevations. Barnett et al...

Transportation-specific runoff and landslide designs require similar data, and many of the standard design calculations used in transportation projects are necessary for landslide-specific surface water control (e.g., peak discharge, flow velocity, etc.).

... initial plan was to get a quantitative understanding of which minerals provided the solute in runoff from Haut Glacier d’Arolla, and to determine how much chemical weathering the warm ice cube in the Alps was undertaking.

... was much higher. We referred to this as a “Variable Pressure Axis” (or VPA) and concluded that it marked the location of a major subglacial drainage channel fed by supraglacial runoff ( Hubbard et al. , 1995 ).

... ). This strongly suggested that there was something unique about glacial runoff that made it a more important vector for the export of organochlorine compounds than runoff in streams fed largely by extra-glacial snowmelt. Completing the organochlorine budget for Bow Lake, Jules found that gas absorption from...

...”, when the snowpack was being removed from the glacier by melting. The runoff volume generated by a glacier this size made it an even bigger challenge to monitor from a hydrological perspective. We did eventually find a way to work there using a combination of judiciously placed camp sites, skidoos...
