Create the original river. The original rivers were firstly automatically generated based on DEM by the hydrological module of ArcGIS, through several calculation process of filling depression, flowing direction, flowing accumulation, and crating river network, similar to most studies 2. The area threshold of rivers was judged by the National River Code of China, which stipulates that the catchment area of major rivers is larger than 1000 km 2. The ASTER GDEM at resolution of 30 m was resampled into 90 m as same as the SRTM data before creating the river. HDMA river data, the global river data released by USGS in 2017, is currently widely used in the world and has a certain reference value, which was used for accuracy comparation 13. Jenson, S.

Verdin, K. L., Hydrologic Derivatives for Modeling and Analysis—A new global high-resolution database. US Geological Survey(2017). In line with Ofwat’s Water Resources Market Information guidance, the information below has been provided to enable third parties to begin to identify opportunities and put forward proposals to us to supply water resources, or provide demand management or leakage services. We have just submitted our Northumbrian Water and Essex & Suffolk Water draft Water Resources Management Plan 2024 (WRMP24) to Defra. A summary of our WRMP24 Best Value Plans is provided below. Northumbrian WaterAt present, scholars and institutions around the world have developed numerous hydrological spatial databases at national, continental and global scales. For example, Seaber et al. constructed the hydrological unit maps of the United States in 1987, which was adopted and affirmed by the Federal Government of the United States and the United States Geological Survey (USGS) 7. In 1996, the Global River Network and Watershed Boundary Data Set (HRDRO 1 K), derived from the USGS’ 30 arc-second digital elevation model of the world (GTOPO30, about 1 km), has been produced by the EROS Data Center of the United States Geological Survey and the United Nations Environmental Program/Global Resources Information Database (UNEP/GRID) 8. From 2006 to 2008, the World Wildlife Fund (WWF), the USGS, the International Centre for Tropical Agriculture (CIAT), the Nature Conservancy (TNC) and Kassel University in Germany have produced a global hydrological data and maps-based (HydroSHEDS) at multiple scales, from the 90-meter resolution data (SRTM) 9. The “stream burning” method was employed to modify the surface elevation where only the large rivers and lakes located 10. Based on the HydroSHEDS data and hydraulic geometry equations, Andreadis in 2013 developed a simple near-global database of bankfull widths and depths of rivers 11. And Bernhard Lehner integrated and enhanced the HydroSHEDS with a new river network routing model (HydroROUT) 12. In 2017, the USGS has developed a new global high-resolution hydrologic derivative database, entitled Hydrologic Derivatives for Modeling and Analysis (HDMA) 13, based on HydroSHEDS, GMTED2010 (Global Multi-resolution Terrain Elevation Data 2010) and SRTM (Shuttle Radar Topography Mission) data. Encouraging third parties to submit bids for solutions covering water resources, demand management and leakage services that create value for customers is very important to us. These solutions will help us meet our future water needs, as identified in our Water Resources Management Plan, and benefit our current and future customers. Our Bid Assessment Framework (BAF) will provide clarity to third parties on the process that we will apply and how bids will be assessed in line with our key principles of transparency, equal treatment, non-discrimination and proportionality. Capacity Available - LoS improvement required = Capacity Available to meet 2032 population targets - Level of service (LoS) improvement required. Leakage reduction and/or capital investment will be required to maintain/improve levels of service as demand increases. These proposals will be developed & prioritised through the National Water Resources Plan and investment planning process. Lehner, B., Verdin, K., Jarvis, A.

We use the L1 WRZ in GRNWRZ V1.0 to determine the initial boundaries and expand it by 50 km to form a buffer. Then, we use them to generate basins and select the complete zone with an area larger than 500000 km 2 as SWRZ. Next, we select the zone composed of several basins of exorheic rivers with a total drainage area of smaller than 500000 km 2 between two adjacent SWRZ as MWRZ. For the endorheic basin, we obtain L2 WRZ through the methods proposed in our previous research 28. Specifically, we expand the boundary of the endorheic L1 basins in GRNWRZ V1.0 by 50 km to form a buffer. Then, we remove the elevation data in the lake area by the land use data 29, creating an outlet for flow for the internally-draining basin, and then we get sub-basins by ArcGIS hydrologic tools. Finally, we combine flow accumulation to dissolve all sub-basins to form L2 EWRZ and SDWRZ. As a fundamental computing unit, the L2 WRZ can perform high-efficiency calculations within limited computer memory, reducing the calculation pressure and the uncertainty of the calculation process caused by hardware limitations.

We've made minor changes to the cover sheet, changelog and Table 8 in each file. This is to reflect the current position of WRMP19 schemes. Information on the water market and the bid assessment process if you have suggestions for new solutions or ways to manage our current water more effectively

Water is essential for everyone. Every day we turn on our taps to fill glasses of water, make cups of tea, wash, cook and clean. We rely on water to run our schools, hospitals and businesses – not just ones we usually associate with water, like car washes and hairdressers, but every industry. It’s also essential for a healthy environment and a prosperous economy. Stein, J. L. An enhanced Pfafstetter catchment reference system. Water Resources Research 54, 9951–9963 (2018).

Our Water Resources Management Plan 2024

We've provided information on key market factors plus our water resources position for each of the six water resource zones (WRZ) in our supply area.This information is in industry-standardised spreadsheets, for the dry year annual average (DYAA) and dry year critical period scenario (DYCP), using templates provided by Ofwat. Major changes from our WRMP19 tables are in the columns for 2020/21 and 2021/22 data in Tables 5, 6 and 7. The values from WRMP19 have been overwritten with figures from our annual reporting.
