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.
Measuring water quantity and quality in surface water (open channels, rivers, reservoirs, lakes, and estuaries) is one of the foundations of hydrological monitoring and has been a focus of OTT Hydromet since its first water current meters were designed in 1875.
Monitoring Sewage Flow is a critical tool for local governments, for water and waste-water utilities and for industrial plants. Sewage monitoring can prevent environmental disasters such as sewage overflow within populated neighborhoods or excessive waste flow into local lakes, rivers or sea. Sewage monitoring is also an important tool for short term and long term planning of the sewers infrastructure. Short term refers to just-in-time and cost effective maintenance. For example, sending the technical team to...
Research programmes demand both technology and affordable products to cover studies from rivers to full ocean depth. Valeport have gained significant knowledge through close collaboration with some of the worlds leading institutes. A clear example of this is our CTD sensor fitted to the seal tags of the Sea Mammal Research Unit (SMRU) of St Andrews University, Scotland as they monitor marine mammal behaviour within their oceanic environment, by obtaining oceanographic quality CTD casts.
Dissolved Species Analysis
Dissolved species analysis employing Hiden's high sensitivity membrane sampling technology for analysis of respiratory gases, hydrocarbons and sulphides is applied to a wide range of application areas including:
Ecolological studies in sea water
Bio fuel production from algae
Pollution monitoring in river, estuary and reservoir waters
Soil core analyses
Monitoring the dilution and movement of a tracer introduced into the water column provides an excellent means of determining the path that may be followed by a discharge and the rate at which dilution is likely to take place. Fluorescent dyes such as Rhodamine, Fluorescein or Agma are the most frequently used tracers for such investigations. Chelsea Technologies has been providing dye tracing systems for over 30 years. Typical applications include sub-sea pipeline leak detection, pollution studies, natural water...
