Global Relationships Between River Width, Slope, Catchment Area, Meander Wavelength, Sinuosity, and Discharge

Inferring air-water temperature relationships from river and catchment properties

Concentration-discharge relationships in runoff from a steep, unchanneled catchment

The observation that “old” water dominates storm runoff suggests that release of low-solute water from soils rather than rainwater must cause storm runoff dilution. This inference is supported by sprinkling experiments in an 860-m catchment in the Oregon Coast Range, in which .200 mm of both high and low ionic strength precipitation produced similar concentration-discharge trends. Rainwater che...

Medial Axis Approximation of River Networks for Catchment Area Delineation

The hydrological catchment areas are commonly extracted from digital elevation models (DEMs). The shortcoming is that computations for large areas are very time consuming and even may be impractical. Furthermore, the DEM may be inaccessible or in a poor quality. This chapter presents an algorithm to approximate the medial axis of river networks, which leads to catchment area delineation. We pro...

Recharge and discharge mechanism and dynamics in the mountainous northern Upper Jordan River Catchment, Israel

Experimental evidence for the conditions necessary to sustain meandering in coarse-bedded rivers.

Meandering rivers are common on Earth and other planetary surfaces, yet the conditions necessary to maintain meandering channels are unclear. As a consequence, self-maintaining meandering channels with cutoffs have not been reproduced in the laboratory. Such experimental channels are needed to explore mechanisms controlling migration rate, sinuosity, floodplain formation, and planform morphodyn...
