... storm runoff, and presenting both a challenge for soil conservation and a consequence of construction and maintenance. We used field mapping, remote sensing, and modeling to assess erosion along the roads and trails in Mount Diablo State Park, which encompasses the headwaters of several urbanized...

... lakes 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...

... a given runoff episode of indeterminate length during early Mars history. We included 13 systems containing both open- and closed-basin lakes, providing fully bounded precipitation estimates (coupled systems). We show that, on average, P T was ≳4 m and ≲159 m; however, local precipitation was spatially...

... 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...

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 ), respectively. The analyses and interpretation results are organized in the form of a hydrogeological conceptual...

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...

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...
