Coastal floods are one of the most dangerous and harmful natural hazards affecting urban areas adjacent to shorelines. Rapid urbanisation combined with climate change and poor governance means a significant increase in the flood risk, posing a greater risk of devastation to coastal communities.

This e-learning module aims to contribute to capacity building of professionals involved in disaster risk management from extreme hydro-meteorological events.  The module represents the means to disseminate the concepts developed within the PEARL project ( It  draws upon the theory and practice concerning multi hazards, holistic risk assessment, development of strategies and selection of measures, and their implementation. There is a pool of case studies in Europe and also Internationally. 

spate irrigation

The Spate Irrigation Network, with support from UNW-DPC and in cooperation with UNESCO-IHE, has produced this series of lectures on Spate Irrigation Systems.

Over the past twenty years, the knowledge and understanding of wastewater treatment has advanced extensively and moved away from empirically-based approaches to a fundamentally-based ‘first principles’ approach embracing chemistry, microbiology, physical and bioprocess engineering, and mathematics. Many of these advances have matured to the degree that they have been codified into mathematical models for simulation by computers.

For a new generation of young scientists and engineers entering the wastewater treatment profession, the quantity, complexity and diversity of these new developments can be overwhelming, particularly in developing countries where access is not readily available to advanced level courses in wastewater treatment. This online course seeks to address that deficiency. It assembles and integrates the
postgraduate course material of a dozen or so professors from research groups around the world that have made significant contributions to the advances in wastewater treatment.

This internet-based curriculum in biological wastewater treatment consists of a more than 40 hours of video-recorded lectures by the author professors all compiled into a DVD package available to those registered for the online course, and of the textbook, lecture handouts, and tutorial exercises for students’ self-study.

The general objective of the Urban Drainage and Sewerage course is to provide an understanding of the basic principles and knowledge for the planning, design and construction of urban drainage and sewerage systems. The course is structured under 7 topics: introduction to urban drainage and types of sewerage systems, urban hydrology and hydraulics, dry and wet weather flow characterization, data collection and processing, design and modelling of urban drainage systems, advanced topics in urban drainage, case studies.

This OCW on Industrial Resource Management and Cleaner Production (IRM&CP) is directed at chemical and environmental engineers and scientists working in the urban or industrial water field and wanting to have a better grasp at the efficient dealing with water.

As such, this course will be of interest to participants who would like to get insight into cleaner production practices in process industries with emphasis in the fields of urban, municipal and industrial sanitation, resource recovery, process design and implementation.

This open courseware set gives an overview of the activities and involvement of UNESCO-IHE in the field of Faecal Sludge Management. Download the new book 'Faecal Sludge Management, systems approach for implementation and operation' below.

toilet Ecological or sustainable sanitation focuses on sanitation beyond providing people with a toilet. It wants to protect and promote human health by providing a clean environment and breaking the cycle of disease. More than that, it aims to be economically viable and socially acceptable; to be technically and institutionally appropriate; and to protect the environment and natural resources.

For many studies models are used or developed. During modelling courses not much attention is paid to the preprocessing of input data and parameters needed for the models. A lot of open source software is available for this purpose. Besides desktop tools with graphical user interfaces, scripting is very useful for processing large datasets and timeseries. With the skills learned in this course you will be able to more efficiently process your data and setup and improve your models.

The Hydrology and Hydraulics course provides lecture notes, presentations and assignments structured under 6 topics: hydrology data, engineering hydrology, free surface hydronamics, hydraulic laboratory, introduction to GIS and introduction to remote sensing.

The Computational Hydraulics course provides lecture notes, presentations and assignments related to the modelling of aquatic. The focus is on problems related to shallow water hydrodynamics and water quality, surges and groundwater. The course focuses in the development and analysis of numerical algorithms for fluid flow problems and the implementation of the computational methods on a PC.
