📝 Overview

This project examines the spatiotemporal dynamics of flood risk within New York State's road networks, with a focus on the performance and behavior of large culvert drainage systems. It includes data preprocessing, hydrologic and hydraulic modeling, model validation, risk analysis, and visualization workflows used in the study.

📁 Repository Structure

The repository is organized into sequential modules that follow the full flood-risk modeling pipeline:

Core Modules

• 1. Data preprocessing/
  Preparation and cleaning of raw datasets, including formatting, filtering, and structuring data for scalable and parallel processing.

• 2. Hydraulic model/
  Implementation of hydraulic computations for estimating culvert discharge capacity.

• 3. Hydrologic model/
  Watershed delineation, hydrologic parameter estimation, and peak-flow calculations.

• 4. Validation/
  Evaluation and verification of hydrologic and hydraulic outputs against reference data and independent models.

• 5. Results/ Confident batch/
  Spatio-temporal flood-risk analysis results and generation of spatial and temporal visualizations across the study region.

Supporting Components

• A.1 AMC/
  Analysis related to Antecedent Moisture Conditions (AMC) and their effect on runoff and peak-flow estimation.

• Environment/
  Environment configuration file and dependencies required to reproduce the computational workflow.

• Image/
  Figures used in the README and related materials.

Note:
The folders are intended to be executed in order, starting from data preprocessing and proceeding through modeling, validation, and results generation.
