Dendrochronology is the science that uses tree-rings dated to their exact year of formation to analyze temporal and spatial patterns of processes in the physical and cultural sciences. There currently is no published record for tree-ring studies using Eastern Red Cedar in the Upper Mississippi River Valley in Wisconsin. Therefore, this study develops a chronology from treerings using Eastern Re...

Traditionally, wines are produced in temperate climate zones, with one harvest per year. Tropical wines are a new concept of vitiviniculture that is being developed, principally in Brazil. The new Brazilian frontier is located in the northeast region (São Francisco River Valley) in Pernambuco State, close to the equator, between 8 and 9 degrees S. Compared with other Brazilian and worldwide vin...

This study investigates the dispersal of the Hudson River outflow across the New York Bight and the adjacent innerthrough midshelf region. Regional Ocean Modeling System (ROMS) simulations were used to examine the mean momentum dynamics; the freshwater dispersal pathways relevant to local biogeochemical processes; and the contribution from wind, remotely forced along-shelf current, tides, and t...

.b rom time to time the existence of typhus has been recorded in Kashmir. In the winter of 1942-43, an epidemic of typhus occurred in Kashmir, and this paper is based on a study of this epidemic. Kashmir is a large valley at about 5,500 feet surrounded by high mountains 12,000 feet high. In the main valley runs the Jhelum river and the tributaries of this river descend from smaller valleys lyin...

Detailed topographic data collected with an airborne laser scanner can help determine the extent of bank erosion and identify banks that are more vulnerable to bank collapse and thus require stabilization efforts. The Minnesota River which flows through a 95% agricultural watershed has been ranked among the top 20 most polluted rivers in the U.S. Greater than 50% of the sediment load carried by...

River classification is a very useful tool for river management yet still a difficult task. This paper proposed a new decision classifier (DCF) to classify rivers for Chinese river management based on existing classification systems. Aimed at river function management, the DCF with the five-layers frame was developed on reach level in a spatially nested pattern that from top to bottom are natur...

Like many montane rivers in the western U. S., the Middle Fork of the John Day River is characterized by alternating narrowand wide-valley segments. Although the river has a low gradient (generally < 0.01) alluvial channel, changes in valley width exert a clear infl uence on channel morphology. A spatial hierarchical model of channel morphology was applied to the Middle Fork to understand reach...

In‐channel large woody debris (LWD) promotes quality aquatic habitat through sediment sorting, pool scouring and in‐stream nutrient retention and transport. LWD recruitment occurs by numerous ecological and geomorphic mechanisms including channel migration, mass wasting and natural tree fall, yet LWD sourcing on the watershed scale remains poorly constrained.We developed a rapid and spatially e...

Glacial mapping combined with cosmogenic exposure dating provides the first detailed assessment of the late Pleistocene glacial history in the northeastern Brooks Range, Alaska. Former ice limits were identified in the Okpilak, Jago, Aichillik, Egaksrak, and Kongakut River valleys. Relative-weathering data support our correlations with the wellstudied glacial sequence of the central Brooks Rang...
