Product Information

E5M2 - it consists of 1 sign bit, 5 exponent bits and 2 bits of mantissa. It can store values up to +/-57344, +/- inf and nan. The tradeoff of the increased dynamic range is lower precision of the stored values. Observed free-surface elevation hydrographs are calculated from Environment Agency measurements of water depth and riverbed elevation above mean sea level ( Environment Agency, 2020). https://www.paraview.org/, last access: 28 April 2023) to plot the non-uniform grid and data. Also, the Predicted water level and velocity hydrographs are shown in Fig. 11. The water level hydrographs show that water ponds in small topographic depressions at point 1 (Fig. 11a), point 3 (Fig. 11b) and point 5 (Fig. 11c). Point 7 is positioned near the steep valley slope and is only inundated between t=1 h and t=8 h (Fig. 11d). At both resolutions, water levels predicted by all solvers agree closely with existing industrial model results at points 1, 3 and 7 (Fig. 4.16 in Néelz and Pender, 2013).

flows. The same tendency is observed for the larger ε = 10 - 3 , with a more notable loss of accuracy in maximum flood extent You must apply for the fee waiver before you make your FLR (FP) application.

Section 3 evaluates the DG2, FV1 and ACC solvers across three flood inundation test cases. The first two cases reproduce Environment Agency benchmark tests ( Néelz and Pender, 2013): the first case simulates a slowly propagating wave over a flat floodplain, measuring computational scalability on multi-core CPU and GPU architectures and comparing the spatial grid convergence of DG2, FV1 and ACC predictions; the second case simulates a rapidly propagating wave along a narrow valley with irregular topography, assessing the solver capabilities for modelling supercritical flow. The final case reproduces fluvial flooding over the 2500 km 2 Eden catchment in north-west England, caused by Storm Desmond in December 2015 ( Xia et al., 2019). This is the first assessment of a DG2 hydrodynamic model in simulating a real-world storm event at catchment scale, with overland flow driven entirely by spatially and temporally varying rainfall data. Concluding remarks are made in Sect. 4. On each grid, the water depth cross section is measured along the centre of the domain (Fig. 7). DG2, FV1 and ACC cross-sectional profiles at the standard grid spacing of Δ x=5 m agree well with industrial model results (Fig. 4.13 in Néelz and Pender, 2013). Differences are most apparent in the vicinity of the wave front, near x=400 m. The solvers are parallelised on multi-core CPU and Nvidia GPU architectures and run existing LISFLOOD-FP modelling scenarios without modification.

Training large models more stably with automatic loss scaling

At a 5 times finer resolution of Δ x=1 m, all solvers predict a steeper wave front, although the FV1 wave-front prediction at Δ x=1 m is still relatively smooth, being closer to the ACC prediction at Δ x=5 m.

As of the 6 April 2023 there is no longer a lifetime allowance (LTA) charge. However, for the 2023-24 tax year the concept of lifetime allowance remains, and benefits crystallising still need to be measured against the lifetime allowance. Where river channel widths are close to or smaller than the grid spacing Δ x, hydrograph predictions are especially sensitive to the channel geometry as resolved on the computational grid. A member must give their scheme administrator the FP 2012 or FP 2014 certificate reference number or the FP 2016 reference number (HMRC does not issue a certificate for FP 2016); this is the minimum legal requirement. The scheme administrator may ask to see a copy of the FP 2012 or FP 2014 certificate or the correspondence from HMRC telling the member their reference number for FP 2016. At the standard resolution of Δ x=5 m, FV1 predicts a wave front about 50 m ahead of ACC or DG2, and the FV1 solution is much smoother.In contrast, the DG2-CPU and FV1-CPU solvers achieve close-to-perfect scaling up to 4 CPU cores, with synchronisation overheads causing only a small decrease in scalability thereafter. Informed by the findings of Ayog et al. ( 2021), the automatic local slope limiter option in LISFLOOD-DG2 is deactivated for the flood-like test cases presented in Sect. 3. The ACC, FV1-CPU and DG2-CPU solvers are run on a 16-core CPU, while the FV1-GPU and DG2-GPU solvers are run on a single GPU. Runtimes are presented relative to ACC for (b) FV1 and (c) DG2: values greater than 1 represent a slowdown relative to ACC; values less than 1 represent a speed-up relative to ACC. Spatially adaptive solvers ( Kesserwani and Sharifian, 2020; Özgen-Xian et al., 2020) and non-uniform meshing techniques ( Kolega and Syme, 2019) offer another alternative to improve flow predictions by selectively capturing fine-scale channel geometries, and such methods are under development for inclusion in a future LISFLOOD-FP release.
