Multi-direction Stream Flowlines for the Upper East River Domain
This map represents estimated stream flowlines from a hydrologically corrected digital elevation model. The lines were derived in the GRASS GIS module r.watershed using a multi-flow direction algorithm that allows channel braiding. Each stream segment is identified by a unique integer.
Single-direction Flow Accumulation Map for the Upper East River Domain
This map represents estimated flow accumulation from a hydrologically corrected digital elevation model. The map was derived in GRASS GIS using a single flow-direction (D8) algorithm that does not allow channel braiding. Values represent the area (in square meters) of land that contributes flow to a
Multi-direction Flow Accumulation for the Upper East River Domain
This dataset represents estimated flow accumulation from a hydrologically corrected digital elevation model. The map was derived in GRASS GIS using a multi-flow direction algorithm that allows channel braiding. Values represent the area (in square meters) of land that contributes flow to a given cel
Surface Water Map at 1m Resolution for the Upper East River Domain
This map represents the estimated binary presence of surface water during the NEON Airborne Observation Platform campaign in July 2018. Values of 1 represent open water, values of 0 represent no water present. Surface water was mapped using imaging spectrometer data from the AOP, and combined with a
Colorado Potato Beetle Control; Asana Wettable Powder Efficacy Trial, Grand Forks, Nd, 1994
Abstract Certified B-sized potato seed was planted at the Red River Valley Potato Growers Research farm on 20 May. Soils were of a finely textured (clay) type. Plot size was 4 rows 36 inch wide and 25 ft. in length. Treatments were arranged in a RCB design, replicated 4 times. Insecticide applicatio
Colorado Potato Beetle Control; Furadan 4F Comparisons, Grand Forks, Nd, 1994
Abstract A field was planted on 11 May using certified B-sized Norchip potatoes. Soils are of a fine texture (clay), and were dry at planting time. Plots were 4 rows 36 inch wide, 25 ft. in length with a 6 ft. alley at the ends. Treatments were arranged in a RCB design, replicated 4 times. Soil trea
Wetlands of the Colorado River Delta Maintained by Agricultural Drainage Water
The delta of the Colorado River in Mexico historically contained 780,000 ha of riparian, marsh, and gallery forest habitat. Similar to other desert river deltas, such as the Nile and Indus, the lower delta of the Colorado River has been severely affected by the upstream diversion of water for human
Microdistributions, food resources and feeding habits of filter-feeding Trichoptera in the Upper Colorado River
A year-round study was conducted in the Colorado River, USA, to examine microdistributions and feeding habits of the filter-feeding Trichoptera (caddisflies) em Arctopsyche grandis /em , em Brachycentrus occidentalis /em and em Hydropsyche cockerelli /em . Only one significant relationship was found
