openLISEM ============ Date: 201201 ============ For questions contact v.g.jetten AD utwente.nl NOTE: only a 64bit version exists, 32 bit is not supported NOTE: The code since version 5.6 is compilable under linux (checked for Ubuntu) NOTE: since version 6 it is fully parallel and developed with MSYS2.0, and openmp version 6.61-6.63 - fixed small bug when using culverts (add rain to overland flow and not channel when culvert) - fixed error in infiltration version 6.5-6.6 - SWOF sediment changed fully parallel computing - maximize parallel comnputing efficiency in all processes - Diagonal (LDD) flow with SWOF when pit in X or Y dircetion using user defined pit threshold - icon changes - NOTE Swatre has not been checked for a while version 6.2-6.4 - bug fixing in sediment - corrections in SWOF 2.0 so that it behaves more as the old SWOF, better now - interface changes - checked infiltration and percolation - further openMP related optimizations version 6.1 BETA (warning: new dlls, do NOT mix with pre 6.0 versions) - fixed bug in getting values from Riemann solver. This was solved before but reappeared! - SAFEST choice for flood modelling is the SWOF without or with MUSCL. SWOF 2.0 is experimental version 6.0 BETA (warning: new dlls, do NOT mix with older versions) - extensive rewriting of the code to use parallel processing with openMP - changed compilation to MSYS so the newest versions of QT and MINGW are used - new 2D flow process (very fast), still being tested version 5.97-5.98 beta - Bug-fix: file runoff.map did not show flood when choosing kinematic+dynamic flow - flow to channel with kin V using perpendicular angle and from channel with gravity - spurious velocities as a result of SWOF limited to sum of kinematic velocity+pressure velocity - Advanced options for SWOF stuff - Outlet shows numer when hovering with the mouse over it - better dealng with highDPI screens version 5.96 - Bug fix: flood height total in mm not reported on screen - Bug fix: did not show all outlets as dots in map display - Bug Fix: Initial food height (whinit.map) was not activated - Interface more consistent on 1D, 1D+ and 2D flow, flood threshold only for 2D - Corrected help files for global options version 5.91-5.95 - fixed: bug in 2D dyn ewave seidment: flow detachment was not working - fixed: impermeable lower boundary was always off - extended options and checked working of sediment traps and grass trips - 3 flow options: 1) kin wave (no flooding); 2) kin wave and flooding from channels; 3) full dynamic wave - river vector display can be toggled and line size adjusted version 5.7-5.91 - fixed buggy 1d kin wave and 2d flood for sediment - revived option kin wave only - cosmetic and code cleaning version 5.5-5.7 - Fixed all sediment MB errors, both simple and two phase flow (suspended and bedload) for 2D flow - Channel displayed as vector and culverts as white dots - colours close to QGIS palettes Still buggy: 1D kinematic coupled to 2D flow for both water and sediment, and sediment classes version 5.5 - Added subsurface stormdrains: kinematic wave on a subsurface LDD network (lddtile.map) with inlets, diameter (pipe), mannings n, gradient - Cleaned up everything so that it compiles under QT 5.13, QWT 6.1.4, mingw 73, revised LISEM_EXTERNAL (no fern) version 5.4 - fixed a bug in SWATRE where the infiltration form SWATRE was not properly subtracted from the surface water layer - Fixed a bug in Green and Ampt using Psi in the wrong units (cm vs. m) - made the calibration for psi also count for SWATRE (this value is multiplied with the inithead maps) - fixed a small bug where the screenshots were not in the right directory version 5.31 - fixed a bug in SWATRE where the infiltration form SWATRE was not properly subtracted from the surface water layer - made the calibration for psi also count for SWATRE (this value is multiplied with the inithead maps) - fixed a small bug where the screenshots were not in the right directory version 5.3 - Fixed a bug in percolation for a 2 layer Green and Ampt infiltration, where the percolation flux was not converted from mm/h to m/s - Fixed a bug that prevented the kinematic wave from causing floods - Added theta1 and theta2 to the output screens when using G&A version 4.94-5.2 - fixed a bug in SWATRE, water level infiltration was not adjusted after infiltration - courant values between dynamic and diffusive wave mixed up in run file - fixed code on reporting cumulative erosion values (may need more work) - added momentum and soil moisture to screen map display - merged output flooding and water height parameters, they were the same anyway - difference between runoff and flood is user choice on water level - Interface: all ',' in the run file replaced with ';' and decimals are always read as '.' - Interface: reset button per tab for default values and better help information - Interface: added variables to map display - Interface: Geotiff file can be used as background NOTE: mass balance errors in erosion modules still possible version 4.92-4.93 - fixed a bug in boudary conditions dynamic wave sometimes causing too much vertical flow - fixed a coding error in erosion slowing down calculations - some interface cleanup (Heun in dynamic wave is not useful) - multicore remains more unstable than single core, and less accurate - Possible bug: flood deposition can become negative and positive (only negative allowed) version 4.91 (180119) - fixed a bug in the screen output causing negative values of discharge and a large mass balance error. Note: when you select dynamic wave flow, the flood height in mm reported is not part of the mass balance, as it is already included in overland flow. version 3.99-4.9 (180116) - added dynamic wave for overland flow, three numerical solutions now: kinematic (using LDD), diffusive and dynamic (using DEM). - Flooding is always solved with a dynamic wave, channel flow is always kinematic. - Random roughness and surface storage slightly changed to avoid bugs in the dynamic wave solution - Multi CPU Core application for paralklel computing. If this gives problems, select only 1 core. - small bugfixes version 3.97 - 3.99 (170308) - BugFix: Calibration factor for Cohesion and Aggregate stability (they were reversed) - BugFix: in Channel Cohesion, soil sohesion was used instead of channel cohesion - BugFix: cleaned up litter interception, roof interception and effect of raindrums - BugFix: ensures that screen information, file and map output is all the same - Added: Fixed bilinear interpolation for sediment, other options give mass balance errors - Added: EXPERIMENTAL: an empirical factor (1-99) to increase the flow in the direction of the steepest resistance slope for diffuse overland flow. - Added: calibration factor for channel cohesion - Added: if the cohesion of slopes or channels is negative, the detachment is assumed to be zero. Deposition will take place - Added: total interception (roofs, canopy, litter, randrums) to the screen output (in mm) - Added: the possibility to write GeoTIFF files for the main map outptu. GTiff is not georeferenced). Tif input is also automatically possible (experimental) - Added: small interface changes to deal with low resolution screens version 3.96 (170211) - Fixed a bug in coupling overland flow and flood water - fixed a bug in automatic adjustment of legend when switching maps version 3.95 (170214) - Fixed a bug in flowboundary conditions - Fixed a minor bug in 2D dynamic flow - Added GeoTiff writing for main output maps (not timeseries) - Added 3 missing fluxes (in mm) to report with totals Version 2.03-3.94 (170212) ================================================================================================================================================ The following features are inplemented in the course of 2015 and 2016: - Multiple catchments can be done in one simulation (limited by PC memory) - Spatial rainfall from rainfall maps (e.g. model results or satellite images) - 1D kinematic wave for runoff and channels based on a usr defined network - Diffusive wave 2D runoff, uses the DEM directly (does not use the LDD which is reserved for the Kinematic wave) - Dynamic wave shallow flooding, based on the FULLSWOF project: https://www.univ-orleans.fr/mapmo/soft/FullSWOF/ - Sediment dynamics (erosion, transport, deposition) for splash, runoff, channel flow and flooding - Flow barriers (walls) can be defined to close areas in 1-4 directions, e.g. as flood protection walls of a given hieght - Channels can be wider than a gridcell - Channel stationary baseflow can be added - Sediment transport for suspended matter only, suspended matter and bedload movement, choice from different transport equations - Sediment transport for a median grainsize class or multiple classes (based on D50-D90 or user defined) - All fluxes are made visible as maps on screen while running, and saved to files - Hydrographs and sedigraphs from multiple observation points and outlets can be shown onscreen while running, and saved to files Because of diffusive runoff the range of resolutions can now be larger, LISEM is being tested from 1 cm gridcells (2 m2) to 20m gridcells (600 km2) 1) The openLISEM model ====================== This is the event based spatial runoff and erosion model openLISEM. Thank you for downloading. openLISEM simulates the spatial dynamics of surface runoff and erosion for catchments of 1 ha to 500 km2. It is based on the LISEM model that is available here: www.itc.nl/lisem. Details about the theory and dataset for now can be found on this website (although a bit outdated). openLISEM uses the freeware GIS PCRaster (http://pcraster.geo.uu.nl) for database creation and analysis of the results. 2) Terms of use =============== This software is free and open source, hosted by sourceforge.net. The project details can be found on: http://lisem.sourceforge.net It is distributed under the GPLv3 licence, distributed with this package Good Luck Victor Jetten Chair Natural Hazards and Disaster Risk Management Department of Earth Systems Analysis Faculty ITC, Twente University, the Netherlands v.g.jetten AD utwente.nl
