Digital elevation models (DEMs) are very convenient for modeling water flow. Some of the applications include delineation of watersheds, flowlines, or deriving useful other useful measures such as the ‘height above nearest drainage’ (HAND, link to another post on this). As a consequence of climate change, the frequency of extreme precipitation events is expected to increase in the future. Therefore, knowing the whereabouts of water is highly relevant and an important tool for the management of surface water in the landscape.
Using machine learning and GIS to predict carbon dioxide in streams
Rain, rain and more rain - 2019 was a very wet year in Denmark and especially September and October were very rainy (DR news). The year ended with 905.2 mm which tied the previous record from 1999. The normal amount is around 700 mm. It continued to rain in 2020 with February and already on February 23 the previous record was surpassed (DR news). The extreme amount of water caused flooding in several parts of Denmark.
