Urban Hydrology
Urban Hydrology deals with the specific aspects of the hydrological cycle in urban and industrial settings. This includes all natural water flows as well as the consideration of precipitation, storm water, groundwater, rivers, and lakes, but also the infrastructure and systems for water supply and sanitation in a city.
OTT sensors and systems provide input data for addressing the various water-related tasks in urban areas, including:
- Acquisition and transmission of rainfall and runoff data for sewage networks and stormwater retention basin management
- Remote monitoring of the water supply infrastructure in order to recognize problems in the pipeline system to prevent and resolve issues of water supply shortage, and minimize costs caused by damage to the water supply system
Hydrolab water quality probes can also measure the effect of urban and industrial activities around surrounding water bodies.
