... construction; and the parking lot in front of the emergency room entrance documented the presence of a doline shaft system (i.e., inter-connected sinkhole). Groundwork for the construction of the new emergency room included grading and leveling of the property. Surface water runoff entered the construction...

... recharged primarily from snowmelt within the last 70 years, while up-gradient surface water is seasonal runoff from rain and snowmelt. Continuous monitoring of dissolved oxygen (DO) mean concentrations (up-gradient = 1.6 mg/L and down-gradient = 5.7 mg/L) indicated that surface water up-gradient from...

... formed by other processes and underlain by other bedrock lithologies lower in phosphorous. These unusually high biogenic sediment accumulation rates produce highly resolved, often annually laminated sedimentary sequences. The result is a high-resolution temporal matrix for the runoff-intensity signal...

... collected were collated, plotted, mapped, analysed and interpreted with the aid of software programs such as AquaChem, ArcGIS, SPSS and PHREEQC. Runoff and evapotranspiration rates were calculated using the SCS Runoff Curve Number method ( SCS, 1986 ) and the FAO Penman-Monteith method ( Allen et al., 1998...

...-fold, fed by terrestrial runoff, leading to a peak in planktonic productivity ( D’Croz et al., 2005 ). In contrast to the SWC, trade winds during the dry season in the tropical eastern Pacific (TEP) drive strong coastal upwelling in areas like the Gulf of Panama ( Fig. 1 ), bringing deep, cool...

... increased the susceptibility of steep slopes in Santa Barbara and Ventura Counties to debris flows. On 9 January 2018, before the fire was fully contained, an intense burst of rain fell on the portion of the burn area above Montecito, California. The rainfall and associated runoff triggered a series...

..., 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...

... includes data from the gauge named “UCD-USGS-2,” closest to the study reaches reported ( Fig. 2 ). In the absence of actual field data for runoff and sediment transport in study channels, data from these gauges provided a proxy for the exceedance threshold discharges that mobilize coarse sediment in step...

... a c. 10–20 cm deep channel during late summer (January–February) runoff, these small channels seldom persist through multiple seasons, because they are seasonally muted and filled with aeolian deposits. We briefly discuss the application of these results to the study of gully systems on Mars...
