This paper presents a combined downscaling and disaggregation weather generator developed for multisite generation of hourly precipitation and temperature time series over complex terrain. Daily regional weather variables are first generated from Generaliz ...
State-of-the-art Discrete Element Method (DEM) simulations of granular flows produce large datasets that contain a wealth of information describing the time-dependent physical state of the particulate medium. To extract this information, both comprehensive ...
This portable system offers fast deployment with no recalibration and maps both vertical and horizontal features while maintaning optimal flight parameters. The geo-referenced image and 3D point-cloud data can be processed into digital terrain models, digi ...
Individual points produced by airborne laser scanning (ALS) may have large variation in their accuracy, a fact that is often omitted in the subsequent derivation of digital terrain models. The accuracy of a single point is governed by three main factors: F ...
This portable system offers fast deployment with no recalibration and maps both vertical and horizontal features while maintaining optimal flight parameters. The geo-referenced image and 3D point-cloud data can be processed into digital terrain models, dig ...
The present paper describes observations, analyses and models of salt-marsh channel network and vegetation patterns with the aim of contributing to the development of predictive models of ecological and morphological co-evolution. Existing and new observat ...
Although landscape is not a recent notion, its place in environmental management is now of major concern. Unprecedented land transformations have become a source of worry in terms of impacts on the landscape. The dynamics are still poorly understood and ne ...
Drainage density (D-d), defined as the total length of channels per unit area, is a fundamental property of natural terrain that reflects local climate, relief, geology, and other factors. Accurate measurement of D-d is important for numerous geomorphic an ...
This paper presents a methodology for the precise registering of airborne laser data directly in flight with an accuracy that is sufficient for the majority of derived products, such as digital terrain models. We first present the strategy that integrates ...
