Soil Evaporation Measurements and Model Predictions for an Underground Dam in Brazil

1,800 mm per year of potential evaporation was measured using the Portable Chamber method in a semi-arid region of Pernambuco State, Brazil. The dataset likely contains soil evaporation values predicted by the SiSPAT model and measured directly under different water table depths. This research was conducted by Fernandha Batista Lafayette and is available via Open Access.

Use Cases

• Validate soil evaporation models based on direct field measurements from the Portable Chamber method.
• Analyze the impact of water table depth on evaporation rates in semi-arid soils.
• Compare the performance of the SiSPAT model against empirical data for different environmental conditions.

Strengths

• Includes direct field measurements using the Portable Chamber method, which allows real-time estimation.
• Model predictions from the SiSPAT model showed a difference of only 1.43% and 4.44% from measured values for specific water table depths.
• Soil hydraulic properties were determined using the Beerkan method to support modeling.

Limitations

• Row count and specific column definitions are unknown, limiting suitability assessment.
• Last update date is unknown; freshness unverified.
• Geographic coverage is limited to a specific semi-arid region in Brazil.
