The vast majority of our grid-scale storage of electricity uses this clever method. Electricity faces a fundamental problem that comes with pretty much any product that’s provided on-demand: our ability to generate large amounts of it doesn’t match up that closely with when we need it. The storage of electricity for later use, especially on a large scale, is quite challenging. That’s not to say that we don’t store energy at grid scale though, and there’s one type of storage that makes up the vast majority of our current capacity.

A weir is a small dam built across a river to control the upstream water level. Weirs have been used for ages to control the flow of water in streams, rivers, and other water bodies. Unlike large dams which create reservoirs, the goal of building a weir across a river isn’t to create storage, but only to gain some control over the water level. Over time, the term weir has taken on a more general definition in engineering to apply to any hydraulic control structure that allows water to flow over its top, often called its crest. In fact, the spillways of many large dams use weirs as control structures. So how do they work?

Engineers need to be able to predict how water will behave in order to design structures that manage or control it. And fluids don’t always behave the way you’d expect. On this episode, we’re talking about one of the most interesting phenomena in open-channel flow: the hydraulic jump.

Dams serve a wide variety of purposes from hydropower to flood control to storage of water for municipal and industrials uses. But when a dam’s useful purpose fades away, the structure itself still remains. Dams come in all shapes and sizes, but contrary to what you might think, the most dangerous dams are often the smallest, also known as low head dams.

Almost everyone agrees that flooding is bad. Most years it’s the number one natural disaster in the US by dollars of damage. So being able to characterize flood risks is a crucial job of civil engineers. Engineering hydrology has equal parts statistics and understanding how society treats risks. Water is incredibly important to us, and it shapes almost every facet of our lives, but it’s almost never in the right place at the right time. Sometimes there’s not enough, like in a drought or just an arid region, but we also need to be prepared for the times when there’s too much water, a flood. Rainfall and streamflow have tremendous variability and it’s the engineer’s job to characterize that so that we can make rational and intelligent decisions about how we develop the world around us.

The course discusses several Geopgraphical Information System (GIS) and Remote Sensing (RS) tools relevant for analysis of (problems in and aspects of) water systems. Within the course, several applications are introduced. These applications include GIS tools to determine mapping of surface water systems (catchment delineation, reservoirs and canal systems). The RS tools include determination of evaporation and soil moisture patterns, and measurement of water levels in surface water systems.

The course will discuss the objectives and functions of water management systems for irrigation and drainage purposes. Analysing system requirements in terms of technical engineering constraints, management possibilities and water users (wishes and options) is central. This includes the design and operation of regulation structures, dams, reservoirs, weirs and conveyance systems; balancing water supply and water requirements in time and space is a main focus of analysis too.

Water is essential for life on earth and of crucial importance for society. Also within our climate water plays a major role. The natural cycle of ocean to atmosphere, by precipitation back to earth and by rivers and aquifers to the oceans has a decisive impact on regional and global climate patterns. This course will cover six main topics: 1. Global water cycle. In this module you will learn to explain the different processes of the global water cycle. 2. Water systems. In this module you will learn to describe the flows of water and sand in different riverine, coastal and ocean systems. 3. Water and climate change. In this module you will learn to identify mechanisms of climate change and you will learn to explain the interplay of climate change, sea level, clouds, rainfall and future weather. 4. Interventions. In this module you will learn to explain why, when and which engineering interventions are needed in rivers, coast and urban environment. 5. Water resource management. In this module you will learn to explain why water for food and water for cities are the main challenges in water management and what the possibilities and limitations of reservoirs and groundwater are to improve water availability. 6. Challenges. In this module you will learn to explain the challenges in better understanding and adapting to the impact of climate change on water for the coming 50 years.
