VIC Model / Distributed Hydrological Modeling Expert Needed We are seeking an experienced hydrological modeler with proven expertise in the VIC (Variable Infiltration Capacity) model and distributed hydrological simulation. This job is specifically for professionals who have previously worked with VIC, forcing generation, gridded climate inputs, hydrometeorological interpolation, and model calibration. ==================== PROJECT OVERVIEW ==================== This project involves building a full VIC-based hydrological workflow for the Shitoukoumen Basin (China). Core work includes: - Generating gridded (0.1° × 0.1°) meteorological forcing from 4 stations - Running VIC to compute daily evaporation for 1960–2020 - Performing calibration using reservoir inflow (1960–2016) - Producing VIC parameters, maps, inputs/outputs, and documentation ==================== TASK DETAILS ==================== 1. VIC MODEL EXECUTION (Daily Evaporation 1960–2020) - Use VIC model to compute daily evaporation for each grid cell. - VIC run must cover 1960–2020. 2. GRID DIVISION (0.1° × 0.1°) - Create the 0.1° × 0.1° grid for the basin. - Provide a grid-division map with IDs for confirmation. 3. METEOROLOGICAL INTERPOLATION (4 Stations → Grid) - Variables: precipitation, air temperature, wind speed (daily). - Stations: Changchun, Shuangyang, Yongji, Panshi. - Produce daily interpolated forcing for each grid cell. - Output each grid cell’s input table separately (Excel). 4. VIC SIMULATION OUTPUT (Per Grid Cell) - Provide daily evaporation results (1960–2020) for each grid. - Output must follow the required formatting (provided sample). 5. MODEL CALIBRATION (1960–2016 Inflow) - Use daily reservoir inflow data for the basin. - Deliver: * Calibration method description * Calibrated parameters * Simulated–Observed comparison plots * Evaluation metrics (e.g., NSE, R²) 6. VIC PARAMETER GENERATION (Per Grid Cell) - Required parameters include: d1, d2, d3, B, Dsmax, DS, Ws, etc. - Summary table (Excel) of all grid parameters. 7. LAND-USE & SOIL DATA PROCESSING - Land-use: University of Maryland 1 km land-cover data. - Soil data: HWSD (Harmonized World Soil Database). - Clip both datasets to the basin boundary. - Produce land-use map and soil-type map compatible with VIC. ==================== FINAL DELIVERABLES ==================== 1. Parameters for each grid cell (d1, d2, d3, B, Dsmax, DS, Ws, etc.) 2. Meteorological interpolation results for every grid cell. 3. VIC input/output files (per grid cell, Excel formatted). 4. All VIC model parameters, charts, evaluation metrics. 5. 0.1° × 0.1° grid-division map (for confirmation). 6. Calibration outputs using 1960–2016 reservoir inflow. 7. All project source files: - Scripts (Python/MATLAB/R/Fortran) - VIC configuration files - Run screenshots ==================== REQUIRED SKILLS ==================== - Strong background in hydrological modeling - Hands-on experience with the VIC model - Experience generating gridded forcing datasets - Spatial interpolation (IDW, Kriging, Spline, etc.) - Hydrological calibration experience - GIS Skills (ArcGIS, QGIS, GDAL) - Familiarity with UMD land-cover & HWSD soil datasets - Strong skills in Python / MATLAB / R / Fortran for automation ==================== WHEN APPLYING, PLEASE INCLUDE: ==================== 1. Your experience with VIC or similar distributed hydrological models. 2. Examples/screenshots of past VIC or hydrological modeling work. 3. Estimated timeline for the full workflow. 4. A fixed-price quote or reasonable range. 5. Any suggestions for workflow optimization. ==================== KEYWORDS FOR SEARCH OPTIMIZATION ==================== VIC model, Variable Infiltration Capacity, distributed hydrological model, hydrological modeling, evapotranspiration modeling, ET modeling, meteorological interpolation, gridded forcing, basin modeling, watershed modeling, hydrological calibration, land surface model, GIS, Python hydrology, hydroclimate modeling.
