Terrain significantly influences the physical processes and human activities occurring on Earth’s surface, especially in mountainous areas. The classification clarification of topographic structures are essential for quantitative analysis surface patterns. In this paper, we propose a new method based digital elevation model to classify binary terrain structure. slope accumulation is constructed...

Landform classification is important for representing soil physical properties varying continuously across the landscape and understanding many hydrological processes in watersheds. Considering it, this study aims to use a geomorphology map (Geomorphons) as an input physically based model (Distributed Hydrology Soil Vegetation Model (DHSVM)) mountainous headwater watershed. A sensitivity analys...

This research was conducted in the coastal area of Parangtritis, Bantul Regency, Special Region Yogyakarta. study aims to describe hydrostratigraphy aquifers using Vertical Electrical Sounding (VES) geoelectric method, calculate volume availability and safe yield groundwater application, compare products with demand for water domestic tourism purposes. uses a field survey approach data analysis...

The objective of this study was to assess the relationship betweenvegetation, landform and physicochemical properties of soil. At the first terrainmap unit were provided using the landsat thematic mapper (TM) satellite images,aerial photograph, topographical and geology map. Field sampling was done in therepresentative area using plot sampling. 104 plots 100 m2 were sampled in eachplot landform...

Landscapes subject to constant forcing tend to evolve toward equilibrium states in which individual landforms have similar characteristics. Yet, even in landscapes at or near equilibrium, there can be significant variability among individual landforms. Furthermore, sites subject to similar processes and conditions can have different mean landform characteristics. This variability is often ascri...

A field study conducted through a series of four field campaigns between 2005 and 2007 investigated the potential for dust emissions around the Salton Sea in California, USA. This paper explores the landform related controls on fugitive PM10 dust emissions from soil surfaces surrounding the Salton Sea by measuring soil properties combined with estimating the in situ PM10 dust emissions using a ...

A raster grid with 1m spacing was created using simple kriging from LiDAR point clouds. The 2, 3, 4, 5, 8, and 10 m resolution were created from the original 1 m DEM using nearest neighbor resampling method. The derived DEM were used to study the sensitivity of terrain attributes while changing DEM resolution and possibly introduce a minimum required resolution for the study area. A variety of ...
