Hi, I can work through the GeoHMS correction first, then carry the cleaned watershed setup into HEC-HMS for rainfall–runoff and reservoir routing, and finally move the routed flows into HEC-RAS for the downstream hydraulic and levee water-level analysis. The workflow will stay traceable so the model files, code, and data package are runnable and easy to review. My approach would include: - Checking DEM preprocessing, stream burning, and watershed delineation in ArcGIS/GeoHMS - Correcting subbasins, reaches, junctions, and hydrologic parameter inputs in HEC-HMS - Setting up reservoir operation/routing and comparing pre- and post-operation flood response - Preparing HEC-RAS boundary conditions, profiles, and time-series outputs for downstream analysis - Organizing source code, model files, and input/output data with clear run steps and QA checks I have more than 10 years of GIS and remote-sensing experience, with strong practical work in ArcGIS Pro, QGIS, spatial analysis, geodatabases, Python, and ArcPy, which is useful.

@bohdan38

Hi, Your project requires an integrated GeoHMS-HEC-HMS-HEC-RAS workflow, not isolated model setup: watershed correction, rainfall-runoff simulation, reservoir routing, and downstream water-level analysis must remain consistent across each stage. The implementation would focus on checking DEM preprocessing and stream networks in ArcGIS/GeoHMS, validating HEC-HMS basin and meteorological parameters, configuring reservoir operation scenarios, then transferring hydrographs and geometry into HEC-RAS for hydraulic calculations and time-series extraction. Model assumptions, inputs, and outputs would be organized for reproducibility. Similar work includes hydrologic and hydraulic workflows involving watershed delineation, flood simulation, reservoir routing, and river modeling. The supplied documents and data can be reviewed to align the implementation with the required research methodology. The first milestone can deliver corrected model files, runnable configurations, key results, and concise documentation within 7 days, with clean structure for later paper preparation. Best regards, Bohdan

@azwa04

Hi, can you share the existing GeoHMS/HEC-HMS/HEC-RAS model files and input datasets so I can first verify where the watershed, routing, or hydraulic setup needs correction? I’ll check the DEM/watershed delineation and river network, validate rainfall-runoff and reservoir routing, then run the pre/post-operation HEC-RAS simulations and downstream water-level analysis. I’ll return runnable model files, source/data files, and clear research-ready results. Azwa

Hello, Primary risk in projects like this is misaligned river network topology from automated GeoHMS delineation that cascades into incorrect HEC-HMS hydrographs and HEC-RAS water-level time series. I will prioritize DEM preprocessing, stream burning, and manual network correction so the upstream inputs driving reservoir routing are physically consistent before any simulation runs. I have executed multiple watershed-to-river modeling workflows combining ArcGIS/GeoHMS delineation, HEC-HMS rainfall-runoff simulation, reservoir routing and operation, and HEC-RAS unsteady hydrodynamic runs. Typical deliverables I produce include corrected GeoHMS shapefiles, HEC-HMS project files with calibrated loss and transform parameters, reservoir operation rule tables used in routing, HEC-RAS geometry and plan files, and time series of downstream levee water levels. I routinely prepare runnable model packages that include source code and scripts for preprocessing DEMs and automating model runs. My first step is a quick data audit and targeted GeoHMS network correction on your DEM and stream layer so subsequent HEC-HMS simulations use correct subbasin and reach connectivity. I will then implement reservoir operation rules in HEC-HMS, run event simulations, export hydrographs to HEC-RAS, and produce levee water-level time series from an unsteady HEC-RAS run. - Do you have the raw DEM, existing GeoHMS outputs, and historical rainfall/gauge records available for the project? - Are reservoir operation rules provided as rule curves or should I derive operational policies from historical releases? Happy to connect for a short call to walk through the approach. Matthew Reese

Hi, I notice the task involves integrating GeoHMS, HEC-HMS, and HEC-RAS for watershed modeling and reservoir routing, which requires careful handling of hydrologic and hydraulic numerical modeling. I'd approach this by first checking and correcting the GeoHMS model, then using HEC-HMS for flood simulation and HEC-RAS for river hydrodynamic simulation. My focus will be on ensuring accurate reservoir operation and flood modeling. In my experience, a common mistake in such tasks is incorrect watershed delineation, which can lead to inaccurate flood modeling results. I'll make sure to carefully preprocess the DEM data and perform stream burning to ensure accurate watershed delineation. The client can expect a thoroughly researched and accurately modeled outcome, with deliverables including source code, model files, and data, all guaranteed to be runnable.

@markkien

Glad to meet you, The main problem of this project is that it requires a highly complex integration of GeoHMS, HEC-HMS, and HEC-RAS models, which demands a deep understanding of hydrologic and hydraulic numerical modeling. I will implement this by designing a modular architecture that separates the GeoHMS watershed correction, HEC-HMS flood simulation, and HEC-RAS river hydrodynamic simulation into distinct components, ensuring consistent data flow and logic. I will reuse existing ArcGIS/GeoHMS tools for watershed delineation and DEM preprocessing, while developing custom scripts for reservoir routing and operation. I will also implement robust consistency checks and edge cases for flood inundation modeling. The deliverables will include the source code, model files, and data, with guaranteed runnable source files, along with a research paper detailing the results and methodology.

Hi, there I have worked on technical modeling workflows where geospatial preprocessing, numerical calculations, structured data processing, and reproducible simulation outputs needed to remain consistent from input data through final results. For this research task, I am planning a reproducible workflow covering DEM preprocessing, watershed and stream-network validation, GeoHMS/HEC-HMS parameter setup, rainfall-runoff simulation, reservoir routing/operation scenarios, and HEC-RAS hydraulic modeling. Model inputs, boundary conditions, time-series outputs, and scenario comparisons can be organized so the delivered project files remain traceable and runnable, with Python used where automation or result processing is useful.
