Topographic Position Index (TPI) The topographic position index was derived to help us distinguish topographic features such as a hilltop, valley bottom, exposed ridge, flat plain, and upper or lower slope. It is calculated by comparing the elevation of each pixel to its surrounding neighbours. T...
How do topographic maps differ from other maps? What type of wave causes coastal erosion? What is soil liquefaction? What is being done to stop coastal erosion in Happisburgh? What is an alluvial plain? What type of regrowth harbors greater biodiversity?

Shifts in regulation and new flood hazard zones: The state of Rhineland-Palatinate, through its regional authority, issued new flood hazard maps (designated flood plain (HQ100) and high risk zone (see in detail [52,53])) a few weeks after the event that includes non-construction zones. The...
The eastern part of the district is composed of Precambrian metamorphic rocks that form steep terrain; the central part is a low plateau with Tertiary sediments and laterites; and the western part is a low plain covered by Quaternary fluvial or partly marine formations (Department of Mining and...
This paper suggests the necessary steps in flood inundation map preparation after determining the possible flood discharge. For this purpose, a set of critical cross-sections along the possible flood plain are taken in the field with surveying methods and measurements. The calculation of the average...
To propose a concept of their mutual diversity, twenty-nine permanent shallow flood-plain pools and oxbows in the river Luznice floodplain were analysed fo... D Pithart,R Pichlová,Bíl, Michal,... - Springer Netherlands 被引量: 51发表: 2007年 Review of applied-statistical methods for flood...
Integrated application of the analytic hierarchy process and the geographic information system for flood risk assessment and flood plain management in Taiwan. Nat. Haz. 59(3), 1261–1276 [15] Das, S., 2019a. Geospatial mapping of flood susceptibility and hydro-geomorphic response to the floods...
and the southeast is mostly plain. Beijing is located in the northern part of the North China Plain, adjacent to the Bohai Bay, bounded by the Taihang Mountains to the west and Yanshan Mountains to the north and northeast, with an average elevation of 43.5 m. The vegetation type is mostly...
The hydrogeomorphological flood hazard mapping in the alluvial plains of Rhumel and Boumerzoug is based on the identification of the functional geomorphological units of the flood plain by using topographic and sedimentological observations as well as the human activities information that allowed us to ...
