bioretention, its applicability to a hot and semiarid region has rarely been evaluated. Existing manuals are developed primarily by studies from temperate-climate regions and focus on residential–commercial uses (3–5). Therefore, bioretention research that addresses hotclimate areas and large-scale highway conditions is needed. To apply bioretention on highway roadsides, design specifications s...

[1] Water scarcity is a critical issue in semiarid regions; however, regional groundwater monitoring is extremely limited. This study evaluates the ability of the GRACE satellites to monitor groundwater storage in the semiarid High Plains aquifer, United States (450,000 km area), which is subjected to intense irrigation. GRACE-derived terrestrial water storage (TWS) is highly correlated with th...

In the arid and semiarid environments of the world, microhabitats serve as models for the structure of vegetation communities. The goal of this study was to identify differences in the structures of the herbaceous communities growing on a crystalline substrate and those growing on a sedimentary substrate in a semiarid region of northeastern Brazil. One hundred 1 × 1 m plots were established in ...

[1] Recent experimental and theoretical studies support the notion that bed load in mountain rivers can both enhance incision rates through wear and inhibit incision rates by covering the bed. These effects may play an important role in landscape evolution and, in particular, the response of river channels to tectonic or climatic perturbation. We use the channel-hillslope integrated landscape d...

Understanding how landscapes respond to climate dynamics in terms of macroscale (average topographic features) and microscale (landform reorganization) is of interest both for deciphering past climates from today’s landscapes and for predicting future landscapes in view of recent climatic trends. Although several studies have addressed macro-scale response, only a few have focused on quantifyin...

Gridded digital elevation data, often referred to as DEMs, are one of the most widely available forms of environmental data. Topographic analysis of DEMs can take many forms, but in hydrologic and geomorphologic applications it is typically used as a surrogate for the spatial variation of hydrological conditions (topographic indices) and flow routing. Here we report on a new flow routing algori...

Abstract The seasonal evolution of the ground thermal regime in cold regions influences hydrologic flow paths, soil biogeochemistry, and hillslope geomorphology. In mountain environments, steep topography produces strong gradients solar insolation, vegetation, snowpack dynamics that lead to large differences temperature over short distances, suggesting a need for high‐resolution, process‐based ...

The Columbia Basin of south-central Washington and north-central Oregon is a major potato-growing region in North America where more than 65,000 ha of potatoes are grown annually. The environment is semiarid (mean rainfall is between 15 and 22.5 cm), and the potato crop is irrigated mostly by center-pivot systems. Although the Columbia Basin is semiarid, potato production is annually threatened...

BACKGROUND At least 511 species of birds occur in the semiarid region of northeastern Brazil and many of them interact with human populations in a number of different ways, including their use in zootherapeutics and their links with local beliefs. OBJECTIVE The present work examined these types of birds/human interactions (use in zootherapeutics and their links with local beliefs) in the semi...
