Ski resorts are high water-consuming service industries, and understanding their water needs is crucial for sustainable water resource management. In this groundbreaking research, scientists from the China National Institute of Standardization have developed a comprehensive model to quantify the water demand for ski resort operations, from winter snowmaking to summer turf management. The study provides valuable insights into the complex interplay between ski resorts and agricultural irrigation, offering solutions for efficient water usage and conservation. By exploring innovative techniques like rainwater harvesting and reuse, the researchers are paving the way for a more sustainable future in the ski industry. This research not only strengthens the methodological foundation for water intake estimation at ski resorts but also offers practical guidance for implementing sustainable water management practices.

Unraveling the Water Challenges of Ski Resorts
Ski resorts are a popular destination for winter sports enthusiasts, but they also pose a significant challenge when it comes to water management. In China, where natural snowfall is often insufficient, ski resorts rely heavily on artificial snowmaking to ensure a thriving ski season. Additionally, the need for lush, well-maintained turf during the summer months adds to the water consumption at these resorts. As a result, ski resorts have become one of the most water-intensive service industries, with an urgent need for a comprehensive understanding of their water usage patterns.
Developing a Quantitative Model for Ski Resort Water Demand
To tackle this challenge, a team of researchers from the China National Institute of Standardization set out to construct a detailed, quantitative model for estimating the water demand of ski resorts. Using a Monte Carlo simulation, they examined the key factors influencing snowmaking water consumption, such as snow density, cumulative snow thickness, and water utilization efficiency.
The researchers found that the theoretical water demand for winter snowmaking ranged from 0.34 to 0.59 cubic meters per square meter per year (m³/m²/year), aligning closely with the national and local norms for water intake at ski resorts. Additionally, they explored the water requirements for summer turf management, estimating a demand of 0.12 to 0.30 m³/m²/year.
Unlocking the Potential of Ski Resort-Agriculture Interactions
The study also delved into the complex relationship between ski resorts and agricultural irrigation. While these two sectors may compete for limited water resources, the researchers identified an opportunity for mutually beneficial cooperation. By leveraging the slope drainage systems at ski resorts, the collected snowmelt and rainwater can be treated and reused for agricultural irrigation during the spring and summer months.
This innovative approach not only alleviates the pressure on local water resources but also promotes development’>sustainable future for ski resorts.
