  Data from 13 catchments with no arable land in Northern Scotland were used to develop empirical linear regression models of average monthly NO3 − concentrations and average summer and winter concentrations for NH4 +, dissolved organic N (DON) and dissolved organic carbon (DOC) as a function of catchment characteristics. All catchments displayed a pronounced seasonal NO3 − by: Recommended water quality limits for rivers and streams managed for Aquatic Ecosystem Health in the Wellington Region June Report prepared for Greater Wellington Regional Council by: Dr Olivier Ausseil Senior Water Quality Scientist Aquanet Consulting Limited Peer-review: Dr Ned Norton, Resource management Consultant, NIWA.

Urbanisation and agriculture represent a dramatic example of human interference in catchment hydrology. The impact of agricultural, domestic, industrial and municipal activities on river flow and water quality within the Upper Manyame Catchment Area (UMCA) was assessed using 7-year nitrate, phosphate and water flow rate data, collected by the Environmental Management Agency (EMA).   Nitrate contamination in groundwater is a worldwide problem especially in agricultural countries. Environmental factors, such as land-use pattern, type of aquifer, and soil-drainage capacity, affect the level of contamination. Exposure to high levels of nitrate in groundwater may contribute to adverse health effects among residents who use groundwater for by:

8 CATCHMENT HEALTH (WATER QUALITY) ENVIRONMENTAL ISSUES GMP 2: NATURAL ENVIRONMENT Ensure settlement growth protects and, where possible, enhances natural features and ecological values of the catchments. As discussed previously in Section 3, water quality is one of the major indicators of the health of a Size: 26KB. Measurement showed that the river level rose by 9 or 10 inches (23 or 25 cm) for every inches ( mm) of rain falling on the river's catchment area. The arrival of railways in the area resulted in a rapid decline of river traffic.⁃ location: Ropsley and Boothby Pagnall.

Thus, for the permeable sub-catchments of the Thames (the Dun, Kennet, Lambourn and Pang), the mean nitrate concentration is around mg NO 3 l − 1 with a range in mean nitrate concentration across the sites of to mg NO 3 l − 1; mean minima and maxima are 20 and mg NO 3 Cited by: The aim of the present study was to determine the variation in concentrations of N and P in samples of river water collected from a range of sites located throughout a mixed land-use temperate catchment area.

The concentration, flux and chemical form of N and P are related to catchment attributes such as land use and soil by: An upper limit on the total annual mass of nitrate removed from river water entering the floodplain aquifer was estimated for the study site ( × 10⁴ kg), which was three orders of magnitude.

Nene Catchment Partnership - Your Water Catchment River Nene Whilton Branch (Upper) The Whilton Branch is a tributary of the River Nene. The water catchment of the Whilton Branch (Upper) is highlighted in black on the map above. This bulletin provides a summary of the available water quality data for the catchment, and some of the.

The impact of agricultural, domestic, industrial and municipal activities on river flow and water quality within the Upper Manyame Catchment Area (UMCA) was assessed using 7-year nitrate, phosphate and water flow rate data, collected by the Environmental Management Agency (EMA).

Consequently, the study serves to focus attention on the long-term increases in nitrate concentration reported in major UK aquifers and the ongoing and chronic impact this trend is likely to be having on surface water concentrations.

For river environments, where groundwater is a source, such trends will mask the impact of measures proposed to reduce the risk of nitrate leaching from agricultural by: Natural concentrations of orthophosphate vary from catchment to catchment depending upon factors such as geology and soil type.

Natural ranges are considered to be approximately 0 to 10 µg P/l. Concentrations of nitrate below mg N/l are considered to be natural or background levels for.

The impact of agricultural, domestic, industrial and municipal activities on river flow and water quality within the Upper Manyame Catchment Area (UMCA) was assessed using 7-year nitrate, phosphate and water flow rate data, collected by the Environmental Management Agency (EMA).Cited by: the data show that Denmark, a country with intensive agriculture and only small rivers, has the highest river nitrate levels; data from five countries on river nitrate levels and agricultural land use in the rivers' catchment areas show a direct link, with small rivers in most agricultural catchment areas showing median concentrations above the.

The impact of agricultural, domestic, industrial and municipal activities on river flow and water quality within the Upper Manyame Catchment Area (UMCA) was assessed using 7-year nitrate.

Concentrations of nitrate-N in the river followed a pronounced seasonal cycle, with maximum concentrations between 10 and 15 mg/L occurring in the spring and minimum concentrations of 0. All river level data, flood warnings, forecasts and alerts are supplied by the relevant national environmental agencies and the Met Office.
