Summary Also known as Model type Single Model part of larger framework Note on status model Date note status model Technical specs Supported platforms Linux Other platform Programming language Other program language Fortran95 Code optimized Single Processor Multiple processors implemented Nr of distributed processors Nr of shared processors Start year development Does model development still take place? No If above answer is no, provide end year model development 2010 Code development status When did you indicate the 'code development status'? Model availability As code Source code availability (Or provide future intension) Through web repository Source web address http://www.glerl.noaa.gov/wr/lbrmexamples.html Source csdms web address Program license type Other Program license type other -- Memory requirements All memory is dynamically sized on the basis of the number of cells in the watershed, so memory requirements are scaled with the size of the watershed. Typical run time In/Output Describe input parameters For every cell in the watershed grid, daily precipitation and air temperature, solar isolation, elevation, slope, flow direction, land use, depths (cm) of USZ (Upper Soil Zone) and LSZ (Lower Soil Zone), available water capacity (%) of USZ and LSZ, soil texture, permeability (cm/h) of USZ and LSZ, Manning's coefficient values, and daily flows (Changsheng He and Thomas E. Croley II, 2007). Input format ASCII Other input format Describe output parameters DLBRM output includes, for every cell in the watershed grid, surface runoff to surface storage, infiltration to USZ, ET, ETP, percolation from USZ to LSZ, interflow from LSZ to surface storage, deep percolation from LSZ to groundwater storage, groundwater flow from groundwater storage to surface storage, surface moisture storage, USZ, and LSZ moisture storages, groundwater storage, and lateral flows from storages to adjacent cells for the surface (channel outflow), USZ, LSZ, and groundwater (Changsheng He and Thomas E. Croley II, 2007). Output format ASCII Other output format Pre-processing software needed? No Describe pre-processing software Post-processing software needed? No Describe post-processing software Visualization software needed? No If above answer is yes Other visualization software Process Describe processes represented by the model Precipitation enters the snowpack, if present, and is then available as snowmelt, depending mainly on air temperature and solar radiation. Snowmelt and rainfall partly infiltrate infiltrate into the soil and partly run off directly to surface storage, depending upon the moisture content of the soil. Infiltration is high if the soil is dry, and surface runoff is high if the soil is saturated. Soil moisture evaporates or is transpired by vegetation, depending on the types of vegetation, the season, solar radiation, air temperature, humidity, and wind speed. The remainder percolates into deeper basin storages that feed surface storage through interflows and groundwater flows. Generally, these supplies are high if the soil and groundwater storages are large. Finally, there is a flow into surface storage from the upstream cell, which is routed, along with all the other flows into surface storage, through the cell into the next downstream cell.
