Abstract Recent forest inventories of North Carolina, South Carolina, and Virginia, included sampling for hydric vegetation, hydric soils, and wetland hydrology. Forest samples that met all 3 of these criteria were classified as forested wetland. This study characterizes wetland forests by extent, owner, age, forest type, physiography, volume, growth, and removals, and evaluates its contribution to the timber supply. Wetland stands comprise 8.1 million ac, or 17% of the forests in the 3 States. They are over 90% privately owned, they vary widely by type and physiography, and they contribute 21

Flash floods have led to disruptions of human activities and the destruction of properties particularly in the Nuweiba region of southeast Sinai.

Abstract Soil management decisions should consider physical potential of the environment, weather variability, and requirements of crops to maximize production to the potential limits.

Abstract:
<p>Understanding peatland coverage and characteristics is essential for improved utilization and conservation efforts. Peatlands in Bangka Belitung Islands, Sumatra, are under threat of illegal mining activities. Creating detailed maps is challenging in Indonesia amid low accessibility, yet the physiographic approach provides an alternative strategy in peatland map provision. This research aims to update peat data in the Bangka Belitung Islands Province, create peat soil maps at a scale of 1:50,000, and estimate peat soil carbon stocks. This research started with a base map using a 1:50,

The mountainous Samian Watershed hosts important rivers recently, significantly triggered by fast and unplanned urbanization, population growth, environmentally hazardous industrialization, and inappropriate dam construction. Nonetheless, this watershed has not yet been evaluated through the lens of river restoration. Therefore, this study aims (1) to apply the River Restoration Index (RRI), (2) to assess the significance of each river restoration criterion and sub-index, and (3) to identify priority hotspots for immediate restoration efforts across 27 sub-watersheds in this case study.

Abstract. This paper presents a detailed analysis of 10 flash flood events in the Mediterranean region using the distributed hydrological model MARINE. Characterizing catchment response during flash flood events may provide new and valuable insight into the dynamics involved for extreme catchment response and their dependency on physiographic properties and flood severity. The main objective of this study is to analyze flash-flood-dedicated hydrologic model sensitivity with a new approach in hydrology, allowing model outputs variance decomposition for temporal patterns of parameter sensitivity

AIM: The reservoirs of the medium and low Tietê River are disposed as a "cascade series", in which time, physiographic features and influence from drainage basins present differences that determine variability in their dynamics. These reservoirs are submitted to different impacts from the urban centres which they drain, and also from agricultural activities.Considering these features, the aim of this work was to characterize the Medium and Low Tietê river stretches by limnological analysis (including water and sediments) considering dry and rainy seasons evaluating changes along the reservoirs

Non-Newtonian debris flows represent a critical challenge for hydraulic infrastructure in mountainous regions, often causing significant damage and service disruption. However, current models typically simplify these flows as Newtonian, leading to inaccurate design assumptions. This study addresses this gap by comparing the hydraulic behavior of Newtonian and non-Newtonian flows in an alluvial fan, using the Amoray Gully in Apurímac, Peru, as a case study. This gully intersects the Interoceánica Sur national highway via a low-water crossing (baden), making it a relevant site for evaluating deb

Abstract:
Gravel barriers represent physiographic, hydrographic, sedimentary, and ecological boundaries between inshore and open marine offshore environments, where they provide numerous important functions. The morphosedimentary features of gravel barriers (e.g., steep, energy reflective form) have led to their characterization as effective coastal defense features during extreme hydrodynamic conditions. Consequently, gravel barriers have often been intensively managed to enhance coastal defense functions. The Blakeney Point Barrier System (BPBS), U.K., is one such example, which offers the opportunity
