Gully head development represents a significant geomorphic process in a wide range of
environments. Several studies investigated the critical topographic conditions, expressed by …

Rivers are important agents of change that shape the Earth's surface and evolve through
time in response to fluctuations in climate and other environmental conditions. They are …

Forest management guidelines are designed to protect water quality from unintended effects
of land use changes such as timber harvest, mining, or forest road construction. Although …

A geometric framework for the automatic extraction of channels and channel networks from
high‐resolution digital elevation data is introduced in this paper. The proposed approach …

地形因素是影响土地利用空间布局的重要因素之一. 以湖南省浏阳市为例, 应用TM
遥感影像数据及DEM 数据, 在ArcGIS 空间分析模块支持下, 采用高程梯度 …

The search for the optimal spatial scale for observing landforms to understand physical
processes is a fundamental issue in geomorphology. Topographic attributes derived from …

The geometric complexity of stream networks has been a source of fascination for centuries.
However, a comprehensive understanding of ramification—the mechanism of branching by …

Extracting hydrologic and geomorphic features from high resolution topography data is a
challenging and computationally demanding task. We illustrate the new capabilities and …

From the origins of hydrology, the time of concentration, tc, has conventionally been tackled
as a constant quantity. However, theoretical proof and empirical evidence imply that tc …

Abstract Height Above the Nearest Drainage (HAND), a state-of-the-art topo-hydrological
index, has been increasingly used in geo-environmental studies. It describes the local …
