This paper intends to investigate the time scales of land surface hydrology and enhance the understanding of the hydrological cycle between the atmosphere, vegetation, and soil. A three-layer model for land surface hydrology is developed to study the temporal variation and vertical structure of water reservoirs in the vegetation–soil system in response to precipitation forcing. The model is an ...

Disturbance plays a fundamental role in determining the vertical structure of vegetation in many terrestrial ecosystems, and knowledge of disturbance histories is vital for developing effective management and restoration plans. In this study, we investigated the potential of using vertical vegetation profiles derived from discrete-return lidar to predict time since fire (TSF) in a landscape of ...

In order to investigate the influence of the vertical variation of porosity on open-channel flow with submerged vegetation, vertical non-homogeneous stumps and stems in submerged vegetation flow are simulated with truncated cones in a laboratory flume. First, porosity is defined as a function of water depth. A new governing equation for vegetation flow is established on the basis of the poroela...

The aim of this study is to understand the relationship between radar backscattering (σ ̋, β ̋ and γ) of a multi-polarized Radarsat-2 C-band image with the structural attributes of regenerating mangrove vegetation located at the mouth of the Amazon River. CBH (circumference at breast height), height and species data were collected to characterize vegetation structure and above-ground biomass (AGB...

Measures of forest structure provide an important indication of productivity, health and the growth stage of a forest. Using traditional field-based approaches, extraction of such structural parameters is often time consuming and labour intensive. Remote sensing is a cost effective technique for mapping and interpreting some features of vegetation; and LiDAR provides highly accurate measurement...

LiteMapper-5600 is a new high-accuracy airborne LIDAR system for corridor and wide-area mapping of terrain and vegetation with a unique feature: it digitizes the echo waveform of each measurement. This paper outlines the system and its components, presents first samples of data that were collected recently with a prototype in flight tests, and analyzes system performance. It highlights applicat...

State of the Problem Lidar remote sensing provides measurements of horizontal and vertical vegetation structure of ecosystems which will be critical for estimating global carbon storage and assessing ecosystem response to climate change and natural and anthropogenic disturbances. However, no consistent approach currently exists to derive the lidar based vegetation structure information required...

Landscape changes associated with urbanization can lead to many serious ecological and environmental problems. Quantifying the vertical structure of the urban landscape and its change is important to understand its social and ecological impacts, but previous studies mainly focus on urban horizontal expansion and its impacts on land cover/land use change. This papers focuses on the residential l...
