Abstract

This repository contains the Monte Carlo simulation ensemble dataset supporting the manuscript "Probabilistic Assessment of Compounding Dam Breach and Flood Hazards in Ungauged, Data-Scarce Watersheds" submitted to xx.
The dataset includes Monte Carlo realizations and ensemble hydrographs generated for the Wadi Derna watershed (560 km², northeastern Libya) across three rainfall categories, produced using the probabilistic flood hazard framework developed in the associated manuscript. The framework propagates uncertainty through the full flood modeling chain, from rainfall–runoff generation through dam breach formation, using HEC-HMS with over 200 uncertain parameters sampled across 10,000 Monte Carlo realizations per rainfall category.

Contents
Monte Carlo Realizations:
Category 1 (50–200 mm): 10,000 parameter sets and corresponding model outputs
Category 2 (200–350 mm): 10,000 parameter sets and corresponding model outputs
Category 3 (350–500 mm): 10,000 parameter sets and corresponding model outputs

Ensemble Hydrographs:
Discharge hydrograph ensembles downstream of Al-Bilad Dam for each rainfall category
Summary statistics including the 5th, 10th, 50th, 90th, and 95th quantile traces for each category
