Ecological Characteristics of Stream Reaches With and Without Low‐Tech Process‐Based Restoration in a Wildfire‐Affected Catchment

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Low‐tech process‐based stream restoration (LTPBR) is increasingly implemented following wildfire, underscoring the need to evaluate restoration outcomes in burned catchments. To help address this need, we measured abiotic and biotic characteristics of a reach that received LTPBR, an untreated reach, and a reach with relict beaver activity that

Computer analysis and mapping of gypsy moth levels in Pennsylvania using LANDSAT-1 digital data [PDF]

open access: yes
The effectiveness of using LANDSAT-1 multispectral digital data and imagery, supplemented by ground truth and aerial photography, was investigated as a new method of surveying gypsy moth (Porthetria dispar (L.)) (Lepidoptera; Lymantriidae) defoliation ...

Geomorphic Responses to Post‐Grazing Recovery and Stream Restoration in Semiarid Grassland Streams

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Semiarid grassland streams are sensitive to land use, climate, extreme discharges, and internal geomorphic thresholds that drive episodic erosion. Rooted in a process‐based philosophy and commonly applied to historically wood‐rich, beaver‐modified systems, low‐tech process‐based restoration using structures is increasingly being extended to ...

Characterization of Landsat-7 to Landsat-8 reflective wavelength and normalized difference vegetation index continuity

open access: yesRemote Sensing of Environment, 2016
At over 40 years, the Landsat satellites provide the longest temporal record of space-based land surface observations, and the successful 2013 launch of the Landsat-8 is continuing this legacy. Ideally, the Landsat data record should be consistent over the Landsat sensor series.

Addressing Biases in Ice Jam Observations by Integrating Multi‐Source Data in a Forested Fluvial Landscape, Southern Quebec

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Exhaustive long‐term and large‐scale ice jam records are scarce in most cold river environments. Many discrete events occur in small, sparsely populated river systems and are poorly represented in open‐source databases. These observation biases are transferred to predictive models of ice jams and the collective understanding of their formation
