Abstract Understanding patterns of expansion, contraction, and disconnection headwater stream length in diverse settings is invaluable for the effective management water resources as well informing research hydrology, ecology, biogeochemistry temporary streams. More accurate mapping network quantitative measures flow duration vast regions facilitate implementation quality regulation other policies to protect waterways. We determined connectivity wet geomorphic channel 3 forested catchments...
Abstract Looking across a landscape, river networks appear deceptively static. However, flowing streams expand and contract following ever-changing hydrological conditions of the surrounding environment. Despite ecological biogeochemical value rivers with discontinuous flow, deciphering temporary nature quantifying their extent remains challenging. Using unique observational dataset spanning diverse geomorphoclimatic settings, we demonstrate existence general hierarchical structuring network...
Abstract A critical challenge for the Earth sciences is to trace transport and flux of matter within among aquatic, terrestrial, atmospheric systems. Robust descriptions isotopic patterns across space time, called “isoscapes,” form basis a rapidly growing wide‐ranging body research aimed at quantifying connectivity Earth's However, isoscapes rivers have been limited by conventional Euclidean approaches in geostatistics lack quantitative framework apportion influence processes driven...
Abstract Despite the advancement of remote sensing and geospatial technology in recent decades, maps headwater streams continue to have high uncertainty fail adequately characterize temporary that expand contract wet length. However, watershed management policy increasingly require information regarding spatial temporal variability flow along streams. We used extensive field data on stream length at different flows create logistic regression models network dynamics for four physiographic...
AbstractLarge wood frequency and volume were examined as a function of landscape characteristics at different spatial temporal scales in 50 reaches the Upper Little Tennessee River basin with drainage areas ranging from 0.3 to 30.1 km2. Riparian forest cover was described laterally reach scale longitudinally 1 km upstream all tributaries. analyzed geomorphic additional variables isolate factors that most influence streams. Forested area immediately surrounding strongest predictor volume,...
