A View of the River

Book Review

A View of the River by Luna B. Leopold, published by Harvard University Press.

Leopold,  A View of the River

Leopold, A View of the River

If you read Barry Lopez River Notes, this book is not that. There is a subtext that comes through—Leopold loved his work, the outdoors life of a river surveyor, and the rivers he studied—but this is not a book of naturalist poetry. What it is, is the digest of a lifetime’s study of the fluvial morphology of small rivers in America. Leopold indicates early on in the preface that he has not done much work on other continents, on big rivers or in tropical climates. However, these limitations acknowledged, much of what Leopold describes can be generalised into wider contexts. The main limitation for New Zealand readers will be the lack of any real discussion about braided rivers.

For students of hydrology and morphology this book could be a primer, or, I suspect, it contains important insights for expert readers too. I am just a student of river projects, and make no claim to any specialist knowledge, but the text is accessible throughout. You don’t have to be a scientist to get a lot out of this. It is a kind of exemplar too, because Leopold presents his findings eloquently, clearly, in plain English, and with plenty of illustrations. If you are a scientist I suggest you buy it, if you are an engineer I am not so sure.

I must give you some examples of Leopold’s knowledge, experience and vision. Hydro engineers will appreciate the value of complete records kept over an extended period of time; the question is always about that minimum flow in years of drought. In Chapter Two, River Measurement, Leopold is discussing the network of gaging stations: “The matter is complicated and will not be treated in detail here. But it is important to realize that many river gaging stations are so affected by the works of man that they do not provide a representation of the hydrology of the river basin”.  A few pages further in Leopold reveals himself as a very practical man, shunning the black art: “The easiest way to measure velocity is by floats, and the best float is an orange peel. It has just the right specific gravity to float nicely at the surface, it is brightly colored and thus easily seen, and it is readily available”. Later, near to the end, Leopold has possibly found some naturally occurring herbs: “The longitudinal profile of a river is concave to the sky”.

I am glad to have bought my copy of A View of the River. I dip into it when I’m in a dreamy mood, and every time I gain some small insight which seems valuable. It is not a thick book, but the text is reasonably dense, such that there is a lot of knowledge contained in just 298 pages.

Slice of the pie

I have to share this! What a great way to do the financials… “I have found over 30 years that most cost overruns can be estimated fairly well by taking the mid-range bid for installation services and then multiplying by Pi. It would be amusing if your formal research supported this anecdotal experience…” —Bill Sepmeier, DC Power and Light, Colorado

Water-mill, Dehradun

Watch this video about the water-mill at Dehradun. Features of this video I found really impressive were: grinding flour close to where you plan to bake the bread; unprotected drivebelts; flat belt drives; and the urban stream diversion channel. Go Manoj Kumar!

Urban stream diversion to water mill.

Just to follow on from that video, are flat belt drives still a good way to transmit power? Yes, they often are the best solution because they are easy to whip off one pulley and onto another, you can see the wear and tear and so plan for renewal, and they are very simple, so they very rarely go wrong. Here’s a good article on flat belt drives.

The fridge knows

I have been measuring what seems obvious, the temperatures in the door of my fridge. What I’m thinking is that if fridge habits could be clustered with television viewing habits a smart micro grid would know a lot about the behaviour of the occupants of a house. This data, along with meteorological data could be used to create a load profile of a) the individual and b) the collective users of a micro grid. This could be used to: make increasingly accurate predictions of the load requirement for purposes of machine downtime and water resource management; create simulations for use in education programmes aimed at improving customer load profiles; and build template profiles to be used in design and planning of other systems.

Blue Covenant

Book Review

Blue Covenant by Maude Barlow,  published by The New Press.

In hardback by The New Press

In hardback by The New Press

This 196-page hardback book is written by the distinguished and celebrated activist Maude Barlow. In the introduction the author describes herself as traveling to, “remote and often wretchedly poor communities around the globe,” and going, “deep inside the global institutions and halls of power”. Barlow writes from personal experience gained on overseas trips (she is Canadian), and from the experience of engaging directly with world politics and policy-makers. Thoroughly researched, this is not an academic book so much as documentary evidence put forward by a practical and sophisticated activist.

Barlow argues that “three crises are coming together globally around water” (video lecture): ecological,  human, and corporate.

Bore wells, shows Barlow, are depleting ground water faster than it can be restored. Water is being moved from one place to another, as in water that is taken from fresh water ecologies, moved to the cities, and then dumped in the ocean. Further, she describes the export of water in produce. She argues that the mismanagment of water is not a consequence of climate change, but one of the causes.

The human crisis Barlow introduces with a shocking statistic, that 2 billion people live in parts of the world that do not have access to clean water. The use of bore wells to access water means sources dry up quite suddenly, provoking aggression between neighbours and between neighbouring states.

The corporate crisis is in the shape of “big private sector interests moving in to create a water cartel” (video lecture). The World Bank is forcing the developing world to adopt a privatised water model. In Chapters 2 and 3 Barlow shows exactly how this has been done, and its consequences.

In the latter part of the book the author describes the rise of the “water warriors”. This emergent group is becoming increasingly cohesive and effective in resisting water privatisation thanks to modern communications networks.

This is not a thick book, nor a dense text, you can read it in a couple or three good sessions. It is a useful reference book to have on the shelf, full of useful examples and statistics. It  has a good references section and a comprehensive index. If you don’t think you have time to read the book go onto Google Videos and search for Maude Barlow and listen to her speak, she is sane and compelling.

The Sardar Sarovar Dam Project

Book Review

The Sardar Sarovar Dam Project by Philippe Cullet (Ed.), published in hardback by Ashgate.

Published in hardback by Ashton.

In hardback by Ashton

This 470-page hardback book is a collection of selected documents with explanatory text by Philippe Cullet. On his home page at the School of Oriental and African Studies, University of London, Dr. Cullet lists his interests as, “Law and environment, law and natural resources, intellectual property, water, human rights, international law, India.”

An overview in Chapter 1 reveals the scale of the Sardar Sarovar Dam Project, the second biggest of the proposed dams on the 1,312 km river which rises at Amarkantak in Madhya Pradesh and flows into the Arabian sea in the state of Gujarat. I chose to read Chapter 1 while flying above the course of the river in Google Earth. For the rest of the book Cullet allows the documents he has selected and retrieved to tell their own story.

The value of these documents for me has been: to know the facts; to note the use of language; to note the form they have taken; and to learn of the extraordinary influence exerted by the Narmada Bachao Andolan.

The Khosla Report of 1965 is here, as is the Morse Report of 1992, of course, that is what you would expect. Where this book becomes so valuable is in the other documents, otherwise inaccessible to students of river projects. For example, the responses from the ministry of Water Resources and the Government of Gujarat. A highlight for me is Mr Chitale’s letter to Mr Vergin of the World Bank in which he writes, “Concerned tribals have been fully compensated… there is no violation of human rights whatsoever so far as Sardar Sarovar Project is concerned.”

It is telling to read the language used to describe the between 250,000 and 500,000 people displaced by the project: PAP (Project Affected Person), PAF (Project Affected Family), and “eligible oustees”.

Running parallel to the story of the oustees, is one of  a “greater common good”. The rationale behind the project is to supply irrigation water, drinking water and power to a vast region that is desperately short of these resources. Whether, in a country known for high levels of corruption, the project can ever deliver even a small part of what it promised to anything like the type or number of people originally targeted to benefit remains to be seen.

This is a sociopolitical book, not an engineering book. It is not for the faint-hearted reader. It will be on my shelf as a useful source of reference for comparison statements. It documents a bleak episode in the history of the World Bank. Every university library needs a copy of this book, I doubt if many individuals do. It is well-structured with a Table of Contents, extensive References, and an Index.

HWP raising support?

High in our sky just now is the Hurunui project, known as the Hurunui Community Water Development, and trading as Hurunui Water Project Ltd (HWP). You can read the project description on MAF’s website. The Community Irrigation Fund (CIF) is “Helping rural communities adapt to climate change by assisting promoters of community water storage and irrigation schemes raise support” (MAF). HWP is using $50,000 of CIF funding to develop its case. In reality the CIF is not so much used to raise support as to fight opposition. This scheme is not popular with the non-farming community, and it prompts the challenge, “define your community”. The CIF “aims to build resilience in agricultural producers and rural communities, and ensure their long-term economic growth within sustainable environmental limits by reducing the risks they face from water shortages caused by climate change” (MAF). The question I want to ask: “Is drought on the Canterbury plain something new, or has it been a threat ever since early settlement?” Is the Canterbury Plain not in the rain shadow of the Southern Alps? Is this climate change… or is it simply the status quo? I’m following the work of  Dr. Andrew Lorrey who is extending records backwards by measuring the growth rings of ancient beech trees at Craigieburn Range in Canterbury (NIWA).
