Recent guidance from Ofwat required a partial update of the tables. We'll provide a full and comprehensive update at a later date. Yamazaki, D. et al. A high‐accuracy map of global terrain elevations. Geophysical Research Letters. 44(11), 5844–5853 (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 would choose the WRX's Premium model with the standard six-speed manual transmission. It offers a good combination of equipment without getting too expensive like the loaded automatic-only GT model. Engine, Transmission, and Performance We will provide 1 in 500 year drought resilience From 2040. We may need to make further sustainability reductions to our abstraction licences in the 2040s (to be confirmed in 2026) which would need further Water Reuse schemes.Verdin, J. P. & Verdin, K. L. A topological system for delineation and codification of the Earth’s river basins. Journal of Hydrology 218, 1–12 (1999). 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. To accompany this statement, we have released a Periodic Indicative Notice (or PIN) via the UK Find a Tender service which outlines the process for third parties to engage with us to offer solutions as part of the WRMP24 process. We chose HydroSHED 9 and HDMA 11 databases for accuracy comparison. They are two widely used global hydrological data sets in which the secondary products (HydroRIVERS 34 and Stream layers) can provide us with an objective comparison. We refer to the comparison method in GRNWRZ V1.0 to compare the accuracy of our RN with HydroRIVERS and Stream layers. It should be noted that few rivers in Stream layers can meet the criteria for rivers at level 7 in GRNWRZ V2.0, so the rivers in Stream layers cannot completely cover the comparison points. Therefore, we only compare with HydroRIVERS at level 7. The comparison is made in the following way: Step 1. We randomly selected 400 rivers from L2-L7 RN of each continent, and three randomly points were generated at each river by ArcGIS (because the Level 1 RN consists of all Level 2 RN that flow into the same ocean, they are essentially the same rivers but divided by different criteria). Step 2. We imported these random points into Google Earth and manually marked the center point of natural rivers nearest to the random point. Step 3. We calculate the deviation distances from the center point obtained in step 2 to rivers in the other two data sets by ArcGIS. Then, we performed statistics in Excel to derive the comparison results.
