Abstract:
... Freshwater discharge through the estuarine reach is always affected by tides and often composed of multiple distributary channels. The current estimation of freshwater input to the ocean by large rivers, therefore, is usually based on discharge measured at some distance upstream of the river mouth. Thus, records, however, may not truly reflect the river discharge to the ocean. In this paper, we co ...

Abstract:
... This paper investigates the implementation of “one village, one product” (OVOP) in four peri‐urban villages in China's Yangtze River Delta. China's agricultural transformation, including the introduction of new corporate actors and the growing pressure of market discipline, has challenged the relevance of villages in the organization of agricultural production. In response, village cadres in thous ...

Abstract:
... The landscape morphology of the Aspromonte Massif, southern Italy, shows hanging low-relief surfaces that correlate with uplifted landsurfaces which are preserved all around the massif. The drainage network has deeply incised the high-standing low-relief landscapes, seen here as being the remnants of phases of relief smoothing prior to strong uplift that has affected the area since the Middle Plei ...

Abstract:
... River plumes are important carriers of terrigenous materials being transported into coastal seas. Previous studies of river plumes focused on large and single river plumes and paid less attention to the plume-to-plume interactions among the small river plumes. In this study, we used the ROMS (Regional Ocean Modeling System) model to study the plume-to-plume interactions in the Pearl River Delta ar ...

Abstract:
... This research introduces a new type of spur (trapezoidal shape) for control of lateral migration of river bend. Trapezoidal spurs (TS) were installed at four different spaces (4L, 5L, 6L, 8L) in a 90 degrees river bend. The same tests also repeated by installing the traditional types of spurs (rectangular shape) for comparison. TS were attached to the flume bank with angle of 30° from bank to the ...

Abstract:
... The Madeira River thalweg includes two pool-to-pool spacing periods. First, standard pool-crossing sequences form 6 to 8 m deep pools. These pool-crossing sequences recur approximately every six channel widths (9.7 km or 6.8 W), on average. However, the Madeira study reach (between Manicoré and Porto Velho in Northern Brazil) is relatively straight, making these pools more frequent than meanders. ...

Abstract:
... For many river basins, flood maps have not been developed, especially in developing countries. Generally, flood hazard maps are generated by a modeling process based on past flood events and require a large amount of input data for the basin. The present study aims to delineate flood-prone areas in the Mekong River Basin from geomorphological features by using linear binary classifiers and receive ...

Abstract:
... During the Late Pleistocene, strong erosional riverine environments led to the widespread occurrence of landslides along the river valleys in southwestern China. Such landslides along the middle reaches of the Dadu River often caused large-scale dammed lakes. In this study, the typical large-scale Jiajun landslide and its associated dammed lake were investigated. The relatively complete sedimentar ...

In reality, however, observing natural processes of a neck cutoff is very difficult. In this study, we artificially triggered neck cutoffs by excavating a 0.4 m (width) × 0.5 m (depth) ditch to connect the beginning and ending of two highly convoluted bends along a meandering trib ...

Pleistocene key sections of the Northern Caspian Lowland are characterized by the incompleteness of the geological record, which is presented in depositional breaks, their duration, causes, and types. Depositional breaks occurred in all periods of the Middle and the Late Pleistocene and occupied various time intervals, usually quite continuous – from ∼180 ka (Cherny Yar) to 100–110 ka (Alexandrov ...
