Spatiotemporal processes that contribute to hydrologic exchange between hillslopes, valley bottoms, and streams

Spatiotemporal processes that contribute to hydrologic exchange between hillslopes, valley bottoms, and streams

Quantifying how watershed structure influences the exchanges of water among component parts of a watershed, particularly the connection between uplands, valley bottoms, and in-stream hydrologic exchange, remains a challenge. However, this understanding is critical for ascertaining the source areas and temporal contributions of water and associated biogeochemical constituents in streams. We used...

Is a vaccine one of the factors that will contribute to the end of the Pandemic?

The covid-19 pandemic began in China in November 2019 and spread globally by March 2020.[2] In India Vaccine research, trials, and production were ramped up gradually. The Covishield vaccine trial was completed by December 2020 and the mass vaccination program started in January 2021. The mortality was far more in western and European countries (despite better health infrastructure) than in Asi...

9 Hydrologic Processes

A catchment is a basic unit of landscape particularly for investigations of hydrologic processes. Typically, the topographic boundary of a catchment coincides with the hydrologic boundary causing any precipitation falling on to the catchment to be routed to a stream where it is transported out of the catchment. Fundamental components of the hydrologic cycle, such as precipitation, runoff and ev...

Variability in isotopic composition of base flow in two headwater streams of the southern Appalachians

We investigated the influence of hillslope scale topographic characteristics and the relative position of hillslopes along streams (i.e., internal catchment structure) on the isotopic composition of base flow in first-order, forested headwater streams at Coweeta Hydrologic Laboratory. The study focused on two adjacent forested catchments with different topographic characteristics. We used stabl...
