Water is very important for farming. Farm dams are crucial for irrigation, cattle, and keeping rural communities alive in Australia and around the world.
But every year, millions of litres of valuable water are lost to evaporation, especially in hot, dry places like much of inland Australia.
Earth dams are vital for water storage, flood control, irrigation, and environmental management. However, their safety and longevity are continually threatened by cracks and seepage—issues that, if neglected, can escalate into catastrophic failure.
Drawing on over 30 years of award-winning dam engineering experience, this in-depth guide provides a comprehensive overview of diagnosing, repairing, and preventing cracks and seepage in earth dams, integrating proven field practices, modern materials, and the latest diagnostic technologies.
Calculating the right dam size and capacity for a farm dam requires balancing water demand, evaporation losses, catchment hydrology, and site-specific engineering factors. Here’s a systematic approach refined over decades of agricultural water management.
Expanding an existing farm dam is a major investment that can transform your property’s water security, productivity, and resilience.
Faced with extended dry periods, many Australian farmers are considering repairing failing or leaking dams to boost their water supply for when the rain returns. However, dam repairs are typically complex and costly projects that should only begin when the root causes of failure and suitable restoration plans are clearly understood.
Evaporation loss from farm dams in Australia is a great challenge to water security, ranging from 9% to 36% loss of total volume of water in summer. Reliable quantification and prediction of losses are complicated by numerous factors that include meteorology, dam shape, and inaccuracies in measurement. This paper explores the complexities of evaporation estimation, the limitations of current practice, and the potential for improvement through advanced modeling and abatement technologies like floating covers and windbreaks. Understanding these dynamics is essential to effectively manage water in Australia’s agricultural regions.
The article discusses how climate change exacerbates heatwaves, droughts, wildfires, and floods. Rising temperatures, altered jet streams, feedback loops, and urban heat islands intensify heatwaves. Changes in precipitation patterns, evaporation rates, and weakened wet seasons worsen droughts. Climate change prolongs wildfire seasons, increases fuel dryness, and leads to more lightning strikes. Additionally, warmer air, sea-level rise, river flooding, and flash flooding contribute to more severe floods. The article emphasizes the need to reduce greenhouse gas emissions, promote sustainable land use, invest in climate resilience, advance climate science, and advocate for policy changes to address these challenges.
Earth dams are versatile structures that serve a multifaceted role in flood control and disaster management. Floods are one of the most devastating natural disasters that can wreak havoc on communities, causing immense damage to property, infrastructure, and, most tragically, human lives. The frequency and intensity of flooding occurrences have risen due to climate change and urbanisation, making it imperative for us to explore and employ effective flood control and disaster management strategies. Among the various flood control measures, earth dams have emerged as vital structures that play a crucial role in mitigating the impact of floods and managing disaster situations. In this thesis, we will dive deep into the significance of earth dams in flood control and disaster management, exploring their functions, benefits, and their role in safeguarding communities.
The New South Wales (NSW) Government is setting its sights on doubling the water supply from Sydney’s $2 billion desalination plant to counteract the anticipated rise in temperatures. According to the World Meteorological Organisation (WMO), Australia is on the verge of experiencing its hottest summer on record in 2024, which is expected to heighten the risk of drought.
Australia is in for a turbulent weekend with extreme weather on both coasts. The west battles a scorching heatwave, while the east faces heavy rains and flash flooding threats. Temperatures in Western Australia’s south-west may reach 39°C, but relief is expected next week. Meanwhile, the east anticipates widespread showers and thunderstorms. South Australia also faces thunderstorms, while Brisbane and the Gold Coast brace for heavy rain. Stay informed and safe amidst this weekend’s meteorological challenges
Preventing and mitigating dam siltation is essential to ensure the long-term effectiveness of these vital infrastructure projects.
Dams are critical infrastructure that provides a range of benefits, from water supply and hydroelectric power generation to flood control and irrigation. However, over time, they face a common challenge known as “siltation” or “silting up.” Siltation occurs when sediment, primarily sand, silt, and clay, accumulates in the reservoir behind the dam, reducing its storage capacity and effectiveness. In this article, I’ll look at the causes of dam siltation and discuss effective strategies and solutions to prevent and mitigate this problem.
Surviving with less water is a skill that can be valuable in various situations, from dealing with water scarcity in everyday life to emergency scenarios in the wild.
Water is essential for life. It’s not just vital for staying hydrated, but also for cooking, cleaning, agriculture, and countless other daily activities. However, in certain situations, such as during droughts, emergencies, or while exploring remote regions, access to ample water may be limited.
In this article, I explore essential strategies and give you tips on how to survive with less water, ensuring that you can adapt and thrive even when faced with water scarcity.
The unpredictability of the drought wreaking havoc in NSW is a stark reminder of the tenacity and will of the Australian people.
Australia, a country renowned for its stark environmental issues and contrasted beauty, is once again facing the terrible power of nature. Currently, towns and farmers in the state of New South Wales (NSW) are struggling due to an unpredictable drought, which poses a severe threat. We go deep into this dilemma in this blog article, telling the moving story of a farmer struggling against the wrath of nature.
Water is one of our planet’s most valuable resources, and managing it effectively is crucial. Dams play a significant role in water management, storing water for a variety of uses, including hydroelectric power production, drinking water supply, and irrigation.
However, dams are not immune to issues, and leakage is one of the most prevalent problems they face. While there are solutions available to address dam leakage, it’s essential to understand that Watersave, a polymer-based product known for its water retention capabilities, may not be the panacea for this particular challenge.
In this blog post, I’ll look at the complexities of dam leakage and why Watersave may not be the solution you’re looking for.
Dams are marvels of engineering. They provide a myriad of benefits like water storage, electricity generation, flood control, and even recreational opportunities. However, the construction of a dam is a complex process that requires meticulous planning, engineering expertise, and strict adherence to safety protocols. Let’s delve into the most common mistakes encountered in dam construction.
Dams are critical infrastructure that serve various purposes, from water supply to flood control and hydroelectric power generation. These structures are designed to withstand the test of time, but like any other infrastructure, they are not immune to wear and tear. Neglecting the maintenance and inspection of dams can lead to costly repairs, environmental disasters, and even loss of life. In this blog post, we will explore why investing just $500 in a site inspection of your dam can potentially save you thousands of dollars in the long run.
