Better completion of fragmentary river networks with the induced terrain approach by using known non-river locations
We improve the precision of our induced terrain approach for completing fragmentary river networks by incorporating known nonriver location data. First, we reconstruct a terrain with known terrain attributes, and then we derive a network passing through all the segments using a river derivation scheme. The original implementation honors height samples and hydrological consistency constraints, w...
متن کاملCompleting Fragmentary River Networks via Induced Terrain
Fragmentary river segments have to be joined appropriately before becoming useful to addressing transportation problems like route planning and pollutant tracking. We suggest the induced terrain approach to complete the job with high accuracy and efficiency. By first approximating a terrain compatible with the partial river segment and height information, and then deriving a river network from ...

متن کاملCompleting river networks with only partial river observations via hydrology-aware ODETLAP
Fragmentary river segments have to be joined appropriately before becoming useful to addressing transportation problems like route planning and pollutant tracking. When height observations are available at the given river locations only, conventional terrain reconstruction techniques often fail to help to classify river/non-river locations at the tributaries. We propose using the hydrology-awar...
متن کاملMonitoring water quality of Prishtevka River based on microbiological parameters
Prishtevka River Basin in the upper part is characterized by hilly - mountain terrain, while the side stretched towards the city of Pristina to the estuary of Sitnica River is characterized by field terrain. 1.5% of the catchment area is situated at an altitude above 1000 m, 33.9% from 1000 m to 800 m, 20.1% from 800 m to 700 m, 25.2% from 700 m to 600 m, and 19, 2% at an altitude below 600 m. ...
